[Elecraft] Kenwood TS-590SG with KPA500 amp?

[Cliff Frescura]

I have an old TS-940 working with the KPA500.  I used the ACC amp
connections on the back on the Kenwood for PTT, which I believe is a DIP
mechanical relay - not loud at all.  In addition, the KPA500 sniffs the
RS-232 line between the Kenwood and my logging PC running DXLabs to
automatically switch bands on the KPA when the frequency changes via the
computer or via the radio.  

73,

Subject: [Elecraft] Kenwood TS-590SG with KPA500 amp?

Hello all:
I have a KPA500 on order to use with my Kenwood TS-590SG (and with my
Elecraft KX3). I would appreciate any suggestions on the best way to
interface the TS-590SG and the amp.
In reviewing the Kenwood manual and some of the Yahoo groups, it appears
that there are at least two ways to interface to the amp. The 590SG offers a
mechanical relay as well as a solid state relay for amplifier switching.
The mechanical relay is apparently fairly foolproof but is noisy. The solid
state relay is quieter or near silent but apparently has some issues in
keying the KPA500. I don't do CW, so rapid keying is not really an issue
with me.
I would appreciate any advice on the best way to interface these two. I
attempted a cursory scan of previous mail list posts but the number of
postings is voluminous. IS THERE A QUICK WAY TO SEARCH PREVIOUS POSTS?
Thanks all in advance for your responses!Steve, N5SKHWeatherford, TX
