Peripherally related...
I have a new-to-me Bird 8890 load.? It's rated VSWR 1.1:1 to 1 GHz, but sweeps substantially worse, rising to nearly 3:1 at 435 MHz.
I've taken the load assembly out of the oil and there's no obvious physical damage.? The load does test 50.02 ohms at DC.
Any suggestions on what to try in order to get this bad boy back online?
Thanks,
