[Elecraft] KAT500/KPA500 with Icom 7600 accessory cable

[Ken B]

Thanks for the suggestion 
Sorry for the delay the wife and I went out. The only way I can get it all to work properly is to:- Remove AC power from the AMP (simply turning it off dowes not work) - On the radio (icom 7600) select the band (ensure auto tuner on Radio is off) - On Radio select AM and depress PTT - While holding PTT, hit the tune button on the KAT500 - Let if get to 1.2 and stop - Let go PTT and select SSB on Radio- Plug in AC power to KPA and power on - On KPA select the proper band- On the KPA select operate from Standby   
All works until I change bands then it is start from the top Cleared all memory 
Wish Elecraft was open on Monday. 
ThanksKen

Ken,

If that Send cable is the only one you have connected between your Icom 
and the KAT500, you need to feed a bit of RF to initiate a TUNE

The KAT500 will first look for a saved L/C combination for that antenna 
and frequency and will switch to that rather than doing a TUNE.  
Secondly, it will compute the SWR and if it is below 1.5, it will go 
into bypass - no tuning is necessary.

Is it possible that either one of those conditions exist?

73,
Don W3FPR
