Completed testing of the home lab stock small RF amplifiers today with the goal of identifying (and fixing or getting rid of) any defective amps. Some of these cover up to 18 GHz although I can only test easily up to 6 GHz with the Pluto SDR and SATSAGEN. Found one bad ZFL-2000 amp amongst those tested (it has a bad stage and likely toast). Plan to test the lab’s larger RF amplifiers before the next local ham fest coming up in September. #HamRadio #TestEquipment #RFAmplifiers #RFTest
