FWIW I'm using a Diplexer on the 145 MHz before the pre-amp, this knocks out the 3rd harmonics. My WIMO crossed Yagis are 2m apart on a fiberglass boom, the SDR is not being overloaded at all.

TX: 100W LSB, TS-2000
RX: NetSDR + RFspace's own down-converter.

When it stops raining & 1 remember I'll take a photo.

The system is working very nicely on FO-29. Total North Americans worked in the last few days - just the one! There's a pass in 150 minutes which would be nice for working into New England and the frozen North :) .

Steve, I have been looking at those same relays.  My biggest concern has been protecting the SDR's & FUNcube Dongle from any RF transmissions.
