SIMPLER VERSION FAQ:
This simpler version is easy to use and takes the guess work out of a
frustrating process that can drive you to drink. That is to say, the
FULL VERSION requires some tedious work setting the TX USER EQ for best
I guarantee you will get results, but the EASY USE VERSION will start
you on your way...
USING SIMPLER VERSION:
Click the DOWNLOAD button located above. Be sure you download the EASY
Save to a directory in your DOCUMENTS. (I suggest
you name the directory Kenwood.)
Unzip the files to a directory inside the Kenwood folder.
(I suggest you name it DSPmodifier.)
Install the files on your computer, remember where you placed the
Run the PROGRAM and follow the menus. Be sure your Kenwood is
communicating with your PC.
Read the following FAQ for running the EASY USE ("Xpress" DSP Modifier).
READ FIRST: If you have not setup your SERIAL
CONNECTION do it now...
READ SECOND: If you have not verified
communication with your Kenwood...STOP.
(1) Make sure that you have a straight through 9 pin DB-9 connector from
the serial port on your PC to the Kenwood TS-2000 DB-9
connector. (Read FAQ below)
(2) Match the COM PORT settings of your PC with those found in MENU 56
on your 2000. The most reliable connection is 9600 BPS. Be sure that
this speed is the same as your COM PORT settings on your PC. If you are
in doubt, please read the PC-SERIAL INTERFACE tutor found further down
on this web page.
(3) Open the KENWOOD DSP MODIFIER program. Make sure the communication
is functioning properly. The program will let you know if connection has
(4) Click on the CONNECT ICON. If your PC is communicating with your
2000, the CONNECT INDICATOR will turn "RED".
NOTE: You may have a ERROR pop up as soon as
you start the program. That is if your DEFAULT COM PORT is set to
anything other than COM1. In the program select your COM PORT and click
"Connect"...the RED INDICATOR should turn on.
(5) Select the SCHEME of your choice and click on UPDATE. The UPDATE light will flash "GREEN" for a few
seconds. It only takes a matter of seconds and mainly depends on the
speed of your PC. When the flashing stops (30 seconds at most) the USER
DATA has been updated and your 2000 is ready.
(6) Close the program now...
Enter the MENU BUTTON your 2000 and set the menus
listed in steps 7 - 9.
(7) MENU 20 on your 2000. Using the +/- keys
(right side of main dial) now set the RX EQ to "USER".
(8) MENU 21 on your 2000. Using the +/- keys (right side of main dial)
now set the TX EQ to "USER".
(9) MENU 22 on your 2000. Using the +/- keys (right side of main dial)
now set the TX BANDWIDTH to "3.0".
Good Luck and have fun using the USER SETTINGS. Remember that if
the EQ is not as you like it, step up to the plate and download the FULL
should give you an idea of the increase of the RX BANDWIDTH that you
will gain using the EASY USE version.
The TX BANDWIDTH will extend to 3.3 when you set the MENU (22) to 3.0.
This will help your TOP end EQ audio frequencies.
Please be sure not to be a frequency HOG. If you are contesting or down
in the 75 METER DX WINDOW, back the MENU down so you are not
Here is the BOTTOM LINE...
The KENWOOD algorithms are "secret code or something"...and I not sure
why. There are no help files listed or available from KENWOOD and when I
tried to get information from their technicians, they simply told me
this was not available...to anyone but KENWOOD certified technicians.
There are no help files for any of the MODIFIER programs. The EXPRESS
version is the best way to go if you are not a computer GURU.
I did notice that the memory offset markers highlighted in YELLOW make
the most difference to the EQ setting. That means 10001000 or 20002000
or 300030000 up to F000F000 will get you started. You cannot do this
without a spectrum analyzer to see the curve as shown above. However
using one of the available computer audio spectrum programs (Sound Card
Oscilloscope) you might get closer than a mile...Throwing numbers at a
wall will accomplish nothing. You should analyze the files included and
listen to the results. Too mich bass, to much mid, pinched sound in the
high end, whatever and then go from there. There is another application
that may help you. I will post it at the end of this article.
Remember these mods are NOT firmware updates, they are nothing more than
a FILTER COMMAND when in USER MODE under MENU 21 and 22. In other words,
no matter what you do you cannot hurt the radio, and, keep in mind, you
do not have to open the radio.
If you do a full radio reset, you will return the radio to USER MODE all
ZERO's and the DSP Modifier will have to be executed again. This also
removes any MEMORY PRESETS you have placed in the radio, so as you can
see, the DSP Modifier does no more than send a MEMORY SETTING to the
offset for the "USER" DSP.
Give it a try...you have nothing to lose and you might stumble on a
great EQ setting for that D-104 you are using...
The FULL version listed below requires TRIAL and ERROR for the best
results. Have at it and see what happens.
THE FULL VERSION:
READ FIRST: If you have
not setup your SERIAL CONNECTION do it now...
READ SECOND: If you have not verified
communication with your Kenwood...STOP.
There are no directions available for the FULL VERSION, so I
will get to it for you. I recommend this modification program over the
EASY USER version because you have better control of the results. Later,
on this page, I will explain the SERVICE
After you have downloaded the FULL VERSION from above and installed it
as required, turn on your 2000 and execute The DSP-MODIFIER program.
You will see the screen to the LEFT. The CONNECT RED INDICATOR SHOULD BE
ON. The com=port should match your PC and the BAUD rate should match
MENU 56 on your 2000. If all is properly set you are ready to use the
Before you make any changes, select the DROP DOWN MENU in the "Command
Viewer" panel. I recommend you start with N3GX PRO. You will see a
series of 2 BYTE offsets in the blue box. Since the EQ is a 16 bit
adjustment, OFF will display all ZERO's from 01-16. Note that all 16
offsets are changeable.
NOTE: N3GX GOLD is designed for the HEIL GOLD
You may adjust any of the OFFSETS for best match to your
microphone for your voice. The procedure is time consuming.
To edit one of the lines, you select that line in the DROP DOWN box and
enter 0-F (16 bit offsets) in the (2) 4 BYTE registry editor box and
click "Accept Changes".
The OFFSET FILE is a TXT file, but it is not located on your computer
and you must create one. In the command viewer, select "OFF". All the
offsets will read "0". Now select a line to edit and "Accept Changes".
Problem is...This may or may not work depending on the Service Pack
installed on your XP system. It may not edit at all in Vista or Win 7.
NOTE: I found this to be the SLOW way to
accomplish the results you are looking for. So I recommend using the
NOTEPAD editor. Follow along as explained here...One more thing I
noticed...the "Update" GREEN indicator will flash on and off and never
stop. Before you click "Update" uncheck "Auto". The offset will be
written in 2-3 seconds.
Forget the EDIT LINE pane because it is truly a PAIN...Select "OFF" for
all "0" and and click "Save" "FILE". Now give this file a NEW NAME.
("EQtest01" would be a good name.) and save it to:
C:\Program Files\DSP_modifier on your system. Now open that file
with NOTEPAD, you will see a string of "0" across one line. Remember
that each line is (2) 4 bit segments or 1 BYTE. To modify line 3, count
16 "0" positions and replace the next 8 BITS with your entry. SAVE the
file and in DSPmodofier click "OPEN" file. the offset you created should
be your entry for line "03".
NOTE: I have added a small file for you to
K3HKR01.txt is located on this website. This file is simple.
It uses 0-F for each SEGMENT. You can save this file to the above
address and click "OPEN" select K3HKR01 and the results will appear in
the blue box above.
If you "OPEN FILE" K3HKR01.txt, you will see 8 BITS, "0" - "F" in each
corresponding SEGMENT of the MEMORY REGISTER. Yes you could write this
to your 2000, it will not hurt anything, but you may get very strange
audio reports. Using your NOTE PAD, replace any of the SEGMENTS with any
8 BIT combination "0" through "F". Save that file with a new name
("EQtest02"). Now "OPEN" that file and verify your changes. To begin...I
suggest you use "N3GX PRO" as a starting point and "Send Command to
Radio"...Check your settings and be sure that you set MENU 21 and MENU
22 ("+"/"-" key) to "USER". Now listen to the results on a separate
receiver or have a friend listen and report.
NOTE: Please use your dummy load.
If you have any computer savvy you can do this after about 2 hours of
experimentation. Using an oscilloscope will help, or use one of the
"sound card" scopes available on the Internet. If you would like to
upload your file settings to the website for others, simply send the
.txt file to the WEBMASTER. I will archive it and place it here for
others to use.

PC SERIAL INTERFACE: HOW TO USE
INTERFACE for your TS-2000 is well defined in your user manual. The DB-9
connector is located at the LOWER LEFT hand side of the rear panel. In
your manual the location is noted on page 13 of section 4 and it is
clearly shown. There are no fancy plugs to buy and certainly nothing too
serious about it's use. The functions are explained on page 50, while
the connections for additional data ports is explained on page 93.
Here is where you may become confused, if you are computer savvy you
will certainly understand that the COM PORT on your PC is also a 9 PIN
connector. This connection may be found on the rear panel of the MAIN
BOARD or a separate PCI interface that supplies 1 or 2 of these ports.
Many early computer models maintained a serial port, however today's
models, especially lap tops do not. Today the standard is USB and it too
becomes a slippery slope for the computer novice. If USB is your only
alternative, follow these simple instructions. If you have a DB-9 on the
computer, you only need a FEMALE to FEMALE direct connection serial
(1) Purchase the KEYSPAN USA-19HS USB to SERIAL adapter. This will
extend your USB out of the computer and allow proper handshake to any
serial device that uses DB-9 connector.
NOTE: There are other units on the market and
Radio Shack has one in it's catalog. This one does not work !! Some of
the other less expensive units may function, but these are not RF
friendly and they also radiate big time, causing EMI interference on
your favorite frequency (especially VHF). Do not waste your time or
money, go get the KEYSPAN.
(2) Now you have a DB-9 connector, but note that you have MALE pin-outs
on both. The radio and the PC (or
your KEYSPAN) will look identical and that ain't going to cut it. You
need DB-9 to DB-9 straight through cable.
Here we go again...You can purchase one of these, but they must be pin
to pin identical and that is often not the case.
NOTE: Radio Shack has a DB-9 female to DB-9
female cable that will work fine. However it is expensive and you can
build one cheaper if you are good with a soldering iron.
Purchasing a FEMALE to FEMALE cable will be a caution. What you get is a
molded cable that in most all cases has PINS 2/3 reversed on one end (3
to 2). This is normal for most applications, but not 2000 CAT. Here is
how you can get around this problem. You need a FEMALE DB-9 to FEMALE
DB-9 cable. As noted, RADIO SHACK has these cables, but you can purchase
everything you need for far less. Two connectors, two covers and 3 feet
of (20 Ga.) 10 wire serial cable and two EMI snap chokes. All this is
available at most electronics stores and yes at "The SHACK"
(3) Now carefully design your cable and be sure to include EMI chokes on
BOTH ENDS. You must wire each pin direct. That is PIN 1 to PIN 1, PIN 2
to PIN2 and so on...When you are completed the last wire remaining
should be connected to the shield. That may be the actual shield that is
around the jacket of the cable.
NOTE: I did not have a shield, so if simple
removed the shield from RG-8X and slid the DB-9 cable through the shield
before I started wiring.
Take a look at the connector above, PIN 5 is SIGNAL GROUND, that is not
CHASSIS GROUND, because SERIAL LEVELS are not TTL levels and you must be
sure that you do not confuse SIGNAL GROUND with chassis ground.
(4) Ok you should be ready to test your cable and set up your radio
connection, but before you do, just in case you have a DB-23 connector
on your computer (I certainly hope not) you can search the Internet for
cable pin-outs. I will add a cable pin-out image here ASAP. If you have
no other choice, I suggest you upgrade now!
Sorry about that...To continue you must understand your serial ports. On
most XP class computers (and above) there will not be a DB-9 connector,
so have your KEYSPAN installed and setup. This is easy, the KEYSPAN
adapter when installed and the drivers prepared properly, your
USB-SERIAL adapter will show in the "My Computer" - "View System
Information" - "Hardware" (tab) - "Device Manager" (button) - "PORTS"
(Com and LPT) "+". Here you should see the KEYSPAN device and the COM
PORT it represents (COM 1,3 or 2,4). Now double click on the device (KEYSPAN)
and the dialog box will appear. Click the PORT SETTINGS (tab) and be
sure to set the parameters as follows: (top to bottom) 9600, 8, none, 1,
none. Now click the ADVANCED (button) and select from DROP DOWN MENU,
any available COM PORT (1-4). Click "OK" and back out.
(5) You are ready to set the TS-2000 in MENU 56. Set the COM
COMMUNICATION to match the KEYSPAN setting at 9600 BPS. This is all you
need to do.
NOTE: You need a communication program to talk
to your 2000. I suggest the KENWOOD ARCP program or HAM RADIO DELUXE.
HRD version 5.0 is a perfect match for the TS-2000. It is easy to
download and install. You can find the DOWNLOAD link on this website or
search HAM RADIO DELUXE on the Internet.
The ARCP application from KENWOOD has a few extras that HRD does not,
but it looks "butt ugly" and it is hard to use. HRD on the other side of
the coin is loaded with lots of applications that run in the back ground
and can be a bit cumbersome. You make your choice, I personally like HRD...and
for this test, it will it is the best application to use.
Turn on your 2000 and then execute HRD. The CONNECT screen appears.
Select a connection TS-2000 and assign the COM PORT your SERIAL or
KEYSPAN adapter is using to communicate. Select the BAUD RATE (9600)to
match your 2000 and then click "connect". You will be prompted if
something is wrong, else you will see the HRD screen with your 2000
frequency listed there.
NOTE: This is not an HRD tutorial. If the
connection fails you have done something wrong. You are
not using a PIN to PIN direct cable or the USB-serial adapter you chose
is not functioning. If you set everything as directed, you will have a
connection. HRD should read TS-2000, COM(n), 9600, - , X, - , X
where the "X" is CTS and RTS (clear to send/ready to send). There is no
error checking for HRD the program "assumes" the connection is present
and maintains CTS/RTS as HIGH all the time. HRD errors will only appear
if the connection drops or is intermittent beyond 500MS.
(6) If you can spin the dial and HRD follows, you are connected to your
2000 and all is functioning properly. I suggest you play with HRD...it
is not the only way to really enjoy your TS-2000, but it is one very
nice interface for the contest user. Virtual sliders, track ball support
and bright buttons replace
menu and radio functions, and there are a few items you cannot do directly,
that HRD can do with a "mouse click".
(7) Now download the suggested programs and prepare to use the DSP
Modifier to set your TX/RX EQ. These programs will communicate and
function as explained only when your computer is connected and the 2000
is ON. If HRD executes properly, your computer and 2000 are
communicating as required.
PC SERIAL CARDS:
The problem many of us face today is the lack of a SERIAL PORT on the
rear apron. Most mother-boards have a set of pin headers that can be
connected to a generic HEADER INTERFACE. The one I have purchased that
works on Intel Main Boards, is the StarTech PLATE9M. This is available
and can be purchased on-line or at any reputable computer outlet. You
can check out the interface configuration on the website. Simply search
the model number above.
is another item you can purchase as well if you need more than one COM
PORT. Some of us control two radios and that will require COM1 and COM2
interfaces. If that is your situation you can purchase a PCI-SERIAL
interface card, also from StarTech. The PCI1S550_LP is a low profile
(single) COM PORT that uses the standard PCI slot. The PCI2S550_LP is a
dual port card. All information is available on the StarTech website.
These work very well and are easy to install into any PC that uses a
standard PCI slot.
The cable issue can be frustrating. You can roll your own or simply
purchase one from StarTech. The cable must be 9 pin to 9 pin direct. No
crossover, female to female. This is NOT A NULL-MODEM CABLE. It
is wired DIRECT all pins 1-9 on both female ends. The StarTech works
fine. The Radio Shack cable is expensive, but it will work with any
Kenwood. The USB adapter from Radio Shack will not work properly so do
not purchase that adapter for the Kenwood interface.
Note that the Intel boards will support both
these items. I use the Intel DH55HC series main board with 3 PCI slots.
I run the TS-2000 at 19200 BAUD with the Kenwood ARCP software almost
exclusively. I update the radio output, frequency and S-meter to my
webcam. The serial connection has never failed. Works great with HRD as
NOTE: Do not contact me with questions
regarding any of the suggested downloads. Please read the disclaimer
below. Please understand that Kenwood, N3GX, HRD and K3HKR are not
responsible for errors encountered. You make any modifications to your
TS-2000 understanding that you alone are responsible.

ARCP TUTORIAL -
How to use this control program for your
The ARCP program written by
Kenwood for your TS-2000 is a rather nice program with a few great
features that other ARCP's do not have. The single most useful feature
is the TX/RX EQ control feature. This program allows you to create an
abundance of EQ and FILTER settings for the DSP your radio uses to
enhance audio IN and OUT.
There are a few other useful items as well and all of this can be
controlled by using a simple interface or serial cable between your
computer USB or serial port and the DB9 input to your TS-2000. The ARCP
can be used in conjunction with the DSP modifier application. Both are
interesting and the DSP modifier allows you to SAVE any setting you
create. I will explain the work around for this a little later.
There are a few items that you must overlook however. First of all the
program is not very neat, or at least not as neat as the TS-2000 layout
or Ham Radio Deluxe ARCP.
The interface is simple, yet effective. Some of the buttons are out of
place and the display can not be configured. The HELP console is not
much help at all. The display uses an ugly AMBER-PEACH color with a rather simple FONT for the items on the
panel. While it is ugly, it is functional and you will find a world of
uses for it, especially if you are on CAM RADIO NET.
Lets get down to business...you must first have the S/N for the original CD
that came with the radio. That is to say, the B-2000 users received the ARCP Ver. 1.02 back in 2001 when the B-2000 was very popular. The first
ARCP was basically the same as today and you will need that CD with the
REGISTRATION NUMBER in order to use the latest ARCP Ver. 1.10. This
version contains a few .DLL files that will allow the ARCP to be run
with Vista and Windows 7. The early TS-2000 (X) users had to pay 39.95
for the ARCP program CD. This was available from the dealer or straight
from Kenwood. You can still get the program, but I suggest you search
around a little, the original CD should be out there and available at a
Now that you have installed the original program, download the
update and follow instructions to install it over top the OEM
application. The latest version is Ver. 1.10, as I mentioned above and
it looks like this:
This is the ARCP application from
Kenwood...Take a minute and look around before I explain this app from

The Kenwood TS-2000 has
several MENU FUNCTIONS, sixty two (62) in all and a few SUB MENU
Getting to these functions is easier in ARCP than using the FRONT PANEL
on your radio. If you are using a B-2000 you may not have a control head
so the ARCP is the only way to go. From the ARCP, select Radio / Menu
and the MENU WINDOW appears as below...
MENU panel lists all your TS-2000 choices
from "00" to "62" and includes, in letters, the SUB MENUS. In the
picture here we have highlighted the FM MIC GAIN menu and we have set it
to MID. In the radio MENU the function requires nothing more than to
select the setting. The change is automatic.
To select the RX EQ function, we would select "20" and in the sub
selector, our choice from "OFF" to "USER". Same for the TX EQ. Unless
you have a great mind and can remember these MENU choices, this is the
best way to make TS-2000 changes.
One thing to remember about ARCP programs, they all have
limitations. Ham Radio Deluxe has some neat little provisions that will
come in handy, but it is not as extensive as Kenwood's program. HRD is
configurable, this one is not. HRD cannot EQ your radio, this one can.
You can use the N3GX DSP Modifier, but in order to change the EQ you
will have to jump through a few hoops to get there. I suggest you stert
here and gain confidence with your radio. I do not believe the TS-2000
will satisfy many users who do not have a computer, it is as simple as
that. But, remember the SDR radios like FLEX and others, you have no
choice but to interface with your PC, and if yours is slow, well it just
is not going to make the grade.
NOTE: There are two types of computer based
radios...the SOFTWARE DEFINED RADIO and the SOFTWARE CONTROLLED RADIO.
The Kenwood TS-2000 is an SCR.
The Digital Signal Processing functions of the TS-2000 are
very useful but Kenwood has left some mystery for a few of us to solve.
N3GX did some of this for us with the DSP modifier, but he left no
tracks to follow. He has no problem with that and I do not either. He,
after all, created the program for himself. He was not greedy but he did
only what he needed to accomplish what he wanted...end of story.
The DSP AF-EQ functions can be found at radio MENU numbers 20 and
21. They each have five selectable positions plus OFF. The USER selection
is one you can design and create personal settings using the ARCP
program. First, with the ARCP running, select from the DSP MENU,
the AUDIO EDITOR / Samples function. You should have a window pop
up that looks like the one below.
There is a DROP DOWN MENU titled (Type). Click on that and select "High
Boost", now use the (Set) selector and choose RX EQ. Now click on
"WRITE" button and confirm the write function. If you are not in the
USER MENU on the RADIO RX EQ, nothing will happen. Go to the MENU
FUNCTION as explained above and select No. 20 and set the EQ = USER. Now
repeat the steps above and you should notice the change almost
instantly. If not, select "Bass Boost 2" and WRITE. You may play with
this function as much as you wish...you cannot hurt anything in your
radio. This is just like inserting a frequency into the radio memories.
It will remain until changed or you do a MEMORY RESET. (Turn on the
radio while pushing the A=B button on the TS-2000 front panel.) You will
lose your EQ setting, but in the next step I will show you how to SAVE
it to a file and re-call the EQ SETTINGS later.
DSP Design Function:
From the DSP MENU, select AUDIO EDITOR / Design. This
will initiate the design window shown here...
is way cool, even though it is a bit mysterious. I told you it would be,
but if you have ever set up a BANDWIDTH filter this should look
There are three MENUS to choose from..."FILE" will allow you to
LOAD and SAVE all filter design (.UDD) files you create. You can also
select an EXIT function from this MENU.
The "DESIGN" MENU offers the "Filter Type" - "Cutoff Freq.1",
"Cutoff Freq.2" plus the "Attenuation". These functions are all
available from the DESIGN CENTRAL window. The "Set" MENU is the WRITE to
radio function that will store your design in the USER RX/TX EQ MEMORY.
Now the MYSTERY...LPF = Low Pass Filter, HPF = High Pass Filter,
BPF = Band Pass Filter and BEF = Band Edge Filter. You can select any of
these and make a series of adjustments. Each adjustment will offer you
changes that can be profound or just simple settings. The first thing
you must do is learn how to create a .UDD file and save it. I created a
"UDD File" folder in the Documents directory and that is where I placed
First I created a simple "TEST.UDD" file which was basically
designed from BEF "Attenuation" = 99 and BPF "Attenuation" = 99. I then
saved that file as "TEST.UDD". Next I created an EXCEL FILE "UDD.XLS"
and made note of the changes. Next I did the WRITE to the radio...it did
exactly what I expected, attenuated the receive signal.
So what do I do now ?? Well you can undo the changes and SAVE a new
file, or simply WRITE the old settings to the radio, the signal levels
should all return. What you should have learned was making the changes
will effect the USER EQ setting instantly, but it will not effect any of
the other settings. You should have also noticed that the CURVES changed
with these adjustments. These UDD files can be opened and viewed in an
editor. They are basically TEXT files, but that is where it all ends. By
saving the OEM files with a filename, I can read these and then check
the range of adjustments, but that will take some additional
understanding of how Kenwood uses the information in the file and that
is the problem; they are not offering this information.
NOTE: I will try
to explain the above, but Kenwood is not going to reveal the information
to anyone (I said that earlier) so take it with a grain of salt.
So let us continue...The LINES in the above file represent POINTS
along the curve. If you look at the SAMPLE window you can clearly see
this. The problem is, something is missing in the plot. That is right,
the GRID index information that would be listed on the LEFT SIDE of the
graph. In order to PLOT the graph, we need to know TWO index points. The
.UDD file seems to be missing the "Y" information. This is the same for
all the plots, LPF through BEF. However do not read anything into the
graph...ATTENUATION will manage (1 - 99) this for you.
Gathering more information reveals:
LINE 1 represents the filter type, meaning "1" is the LPF, "2" is the
HPF, "3" is BPF and 4 will be the BEF.
LINE 2 represents the LPF setting (effected by HPF
LINE 3 represents the HPF setting (effected by LPF
LINE 4 represents the BPF setting, but adjusting this setting will also
effect the LPF and HPF as well.
LINE 5 represents the ATTENUATION setting you chose for your design.
This adjustment will not effect any of the other 4 "Types". I suggest
you set the ATTENUATION at "1" for your experiments.
NOTE: You must remember that if you are going
to "Design" DSP EQ files, you should save them with "TX" or "RX"
somewhere in the filename. (Example: RXTEST2.UDD would be your "Receive
EQ" second TEST file.)
I have searched the entire Internet looking for .UDD files. I have
found nothing and I don't think you will either because most Amateur
Radio operators are not going to take the time to gather this
information, let alone offer the results to anyone. You must understand
LOW PASS and HIGH PASS filters and how they effect BAND PASS. This
information is not covered here because the Internet can do that for us.
Use your browser "search engine" to find articles explaining Start with
the BAND PASS FILTER, it is the easiest to understand. Now try building
your own BPF for the Kenwood. Go ahead, "Write" it to the radio. Did
anything happen ???
Several of the features displayed above have additional details here...
Tuning: This is the poorest excuse
for a RADIO DIAL that I have ever encountered. There is however a good
way to use this button. Clicking on the KNOB (???) will toggle the color
GREEN and the knob can be manipulated to turn almost like the real
dial...yeah sure, but fear not, if you have a wheel mouse a simple click
will activate the wheel and you can tune up or down the band using the
WHEEL on your mouse. Better yet...there is a USB JOG SHUTTLE that looks
and feels like a DIAL, this can be used to TUNE the ARCP, just like a
real main dial. This is very cool if you are using remote operation from
your work computer.
SATELLITE OPERATION: Is a
click away for those of you who have the "X" radio. If you do not, you
will simply be taken to the SPLIT 70 Cm mode with 2 Meters. You can
access this menu function using the TX RX
/ Satellite selection. The More about this function in your
The real difference for your TS-2000
comes after you make a few modifications. These are simple but they do
require some surface mount technology understanding and a good CERAMIC
tip, low wattage pencil iron. If you need a service manual, you can get
that here as well, from our DOWNLOADS section.
RX/TX Modification: This mod requires you to open the radio. Remove
the TOP and BOTTOM covers. Set them aside along with the hardware. If
you look closely along the sides of the radio near the front panel, you
will see four (4) screws that hold the CONTROL HEAD in place. Remove
these, two on each side. Now carefully pull the control head straight
out from the chassis, be careful, there is a ribbon cable (CN4) that
connects the head to the control board.
The 3 resistors we want to remove are located on this board in the
LOWER LEFT hand corner, just right of the FAN. You should see a series
of JUMPERS. These are SURFACE MOUNT resistors.
You will be removing three of these resistors. Be careful to HEAT only
the resistor. Using a set of tweezers, remove the resistor from each of
the SM pads.
Now reverse the steps and re-assemble your TS-2000. For these new
functions to operate, you must do a CPU reset, so turn on the TS-2000
while holding the A=B key in. This reset will erase any memories, but if
you use the MCP-2000 program, you should already have a backup of those
memories and can simply re-program the radio.
(R52) will expand the RX frequencies. This will allow you to hear
220 MHz and a few other frequencies that are useful as SWL or WEATHER
stations. You will now receive SUB-BANDS that lie between 118 to 174 MHz
and 220 MHz to 512 MHz. This is not an increase in receive potential,
but it will allow you some flexibility in the VHF/UHF bands.
(R53) will expand the TX frequencies. Removing this resistor and
you can operate MARS or 60 Meters which will be undergoing some FCC
changes this Fall. You can operate 100 watts on 60 Meters after the
changes and one new channel will be added. This alone will make your
TS-2000 more flexible. The new transmit frequencies are: 1.7 - 30 MHz,
49 - 54 MHz, 152 - 152 MHz and 420 - 450 MHz. The additional HF
allowance is worth your time and energy.
will expand the special features: These are SkyCommand, External
Remote Operation and Cross-Band Repeat. All of these specific features
are listed on the Kenwood website, but basically SkyCommand puts an HF
rig at your finger tips as long as you have a Hand Held 2M FM radio to
control the TS/B-2000. The next feature is CROSS-BAND Repeat...this
function allows you to use the TS-2000 like a repeater. You can operate
10 Meter FM from your UHF 440 handheld. You can operate a SSB net too.
The CROSS-BAND function is documented in the user manual. There is also
an EXTERNAL REMOTE function that you can use. From any PC via the
Internet, you can operate your TS-2000 at home. Sending commands to the
radio can be done by using the ARCP program directly on your REMOTE PC
desk top using one of the REMOTE DESK TOP applications available on the
Internet. As you can see, it is worth your effort making these three
The images above along with this picture of the actual resistors located
on the CONTROL BOARD will help you complete the steps above. Start with
R53 and then R52. This will allow the solder to be removed and you will
have a clean set of PADS if you ever decide to undo these changes. The
cable CN4 is the main cable for the CPU and READ-OUT boards inside the
head. Be sure not to damage this cable and be certain no solder splashes
come in contact with the connector. You are working in a small area here
and a little caution will result in a job well done. Please no 125
watt solder guns in here.
I hope you enjoy these modifications. I will listen for
you on 60 Meters...K3HKR

Please follow these links for additional details.
The Memory Control is available here...
Download the software and
un-zip to a folder of your choice.
Using of the
program is rather self explanatory.
First the "Menu", where you can look at all TS-2000 menus that are set
in your radio. You can make changes from here without having to play
with the MENU button on the radio. This is the same as the MENU CONTROL
in the ARCP application.
Set the KEY ILLUMINATION on the fly, and turn it off during daylight
hours. Set the SIDE TONE volume or BEEP VOLUME all in the same manner.
You can then turn the volume down for late evening operation.
Menu "B" is also easy to use but best of all, you have access to DCD
sense and TNC control. At the click of a mouse. Try that during a
contest when you need to change a value quickly.
You can Even set a comment to display as a reminder next time you use
the MEMORY CONTROL.
The "Memory" settings are simple. Highlite the CH (channel) you desire
and "double click" on the choice. A smaller POP-UP will appear and you
simply edit your frequency and other information that will support MAIN
or SUB band operation. Yes, you can set tones for repeater operation as
The rest is simple stuff...have the radio on and COM PORT
communications running. Do your thing. You will enjoy the flexibility of
the MEMORY CONTROL PROGRAM from Kenwood.
