actually that is just as good as any way. the monitor itself is wideband from 200khz-54mhz the RFA-1 is what makes it a super sensitive and selective receiver and monitoring system :) the rfa-1 is a simple device so if there is no burnt part and the test points check out than it is probably good. I traded the Belar to the Delta monitors and the belars are in use at a actual am station. and the delta's just came from that station and they are working condition. i saw the delta in place and in operation a month or so ago and it was working perfect then.
