[Elecraft] high input SWR KPA500

[Steef PA2A]

John,

it is the same with all transceivers. In standby everything is OK and 
input power is shown on the KPA screen. But in operating mode the signal 
blocks somewhere. The RF of the TS590S doesn 't even switch the band 
filters of the KPA while it does switch them in standby mode. I suspect 
the input relay or circuit. There may have been DC in the coax line 
caused by a remote beverage switch.

The amp shows 0.5 Ampere current when PTT is applied. Not very much so 
there may be more trouble.

CU all in the PACC, starting within a few hours!
