[Elecraft] Using SunSDR2 pro with KPA500

[Don Wilhelm]

Stephen,

What is needed is a KeyOut from the driving transceiver - that is an 
output which is grounded when the driving transceiver goes to transmit.
The KPA500 will frequency sense if it receives a short burst of RF, so 
the band data is not necessary, just connect the transverter and 
amplifier in the Basic Configuration.

You will have to consult with the SDR transceiver folks to see if there 
is a KeyOut connector (I did not see one when I looked a some of the 
ads).  Without that, the SunSDR2 cannot key any amplifier.
