New Kenwood TS-590 Setup Recommendations
Kenwood's exciting new TS-590S transceiver promises to be popular among active operators throughout the world. We are already getting a lot of questions about the best "settings" for the on-board DSP microphone equalizer.
The TS-590S does have a very sophisticated software-programmable equalizer system, but that's not required in order to get on the air while sounding great.
Menu items 25 and 26 set the transmitter's bandwidth. Leave them at factory defaults to get started; they'll set you up for a low-end cutoff of 300 Hz, and a high-end cutoff of 2700Hz.
Now go to Menu #30, and select "C" ("Conventional"), which will give the audio frequencies above 600Hz a slight (3 dB) boost. That will be good for starters. You may also select "HB2" (High Boost 2) if you're using a wide-range microphone, like the PR 781, on the TS-590. The High Boost 2 selection will suppress the lower frequencies, and give you more "sparkle" on the high side, for good communication-quality audio.
Ultimately, though, much of the fun of acquiring a new radio is the experimentation with its many features. Read the operating manual, especially on page 32, and then try out the many available bandwidths and equalization possibilities. Listen to yourself on a separate receiver, with its antenna disconnected and its noise blanker turned off, to know exactly how you'll sound to others listening to you on the air.
For best results please consult your manual.
