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

[Steven C Veal]

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
