Using SunSDR2 pro with KPA500

[Stephen G4SJP]

Does anyone have any experience of fully interfacing this SDR with the
KPA500 please?  I confess to be rather confused.  I am looking to configure
the Ext Ctrl tables with the BCD values that the KPA500 requires for band
switching etc.  I understand what BCD is, but in this context I'm confused
as to how to define it in the SDR's setup.

Thanks and 73

Stephen, G4SJP

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.

You might want to try the forums for the SDR  radios because their have been discussions on this very topic.  Hope this helps.
