If you own a Kenwood TS-2000 transceiver, you probably already discovered that it contains powerful DSPs (digital signal processors). They are used at several points in the signal path, and also the audio from the microphone and to the loudspeaker gets processed by a DSP. The radio allows activating a user defined profile for the audio (“USER” in menu #20 for RX and menu #21 for TX), unfortunately Kenwood decided not to provide any kind of equalizer software, perhaps to push the TS-590 a bit.
Alex N3GX wrote a software called “DSP Modifier” a few years ago, and included four very nice profiles. They give a much better sound, compared to the built-in settings of the TS-2000. Unfortunately it is absolutely unclear how Alex created the profiles. Furthermore his software requires to enter signed hexadecimal numbers, which is not user friendly at all.
So I decided to write a similar software and use sliders instead. After finishing the programming I discovered that there is no simple relationship between the numbers and the audio spectrum. At least I recognized that we have 32 WORDs instead of 16 DWORDs. So the current version got 32 sliders.
You can download it directly here:
The usage of my software, called “TS2000EQ”, is more or less self explaining. Select the com port and the baud rate (see menu #56 in the TS-2000) and click on “Connect”. Then select “Send EQ” or “Recv EQ”, depending on what equalizer you want to modify (TX or RX). And load a predefined setting as a starting point. If you select the check-box “Automatic”, every slider movement will be directly written into the TS-2000, and you immediately hear the result. The software stores the last settings in the Windows Registry.
Please let me know if you understand how the sliders representing the 32 values influence the audio spectrum.
