DSP MODIFIER (Free of charge written by N3GX)

Be sure you read this first:
All the applications found on this document will require PC-SERIAL communication with your TS-2000 CAT input. If you have never done this before, I suggest you read my small tutorial posted here. Please read the DISCLAIMER located at the end of this page...Thank you


Here is the N3GX DSP MODIFIER, download for 3.3 KHz Transmit with 4 KHz Receive and USER EQ settings.
(1) FULL VERSION by N3GX, please click the DOWNLOAD.            
(2) EASY USE VERSION by N3GX, please click the DOWNLOAD. 

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 results.
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 USE VERSION.
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 executables.
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 been made.
(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 VERSION.

This 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 interfering.










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 MONITOR application.
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 program.
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 LINE microphones.
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 download. 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.

To Be Continued...If you can add something here, please email the WEBMASTER.

PC SERIAL INTERFACE: HOW TO USE

The 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 cable.
(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 from www.StarTech.com 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.
There 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 well.

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.

HAVE FUN- K3HKR

   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 reasonable price.
   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 top down.

The Kenwood TS-2000 has several MENU FUNCTIONS, sixty two (62) in all and a few SUB MENU functions also.
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...
The 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...
This 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 familiar.
   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 the folder.
   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.
