I tried a cheap TQ2SA SMD relais for RF switching. The circuit was using the 2 switches as one SPDT switch with the unused output connected to ground.
Find some pictures attached. For low power it should be possible to use the relais up to 70cm (ok, 30dB isolation only). On 2m and below it works with good results…
During July V/U/SHF contest another 43km laser communication trial with DK5WMA.
Locations were JO60LK and JO60MT during the sunset.
