Isn't it the truth. The MASTR PRO used to do .5uV / 20 db on VHF with NO problem tuned by the book, but UHF was a bit touchier it took the added tuning devices of a few rubber fingers and several prairs to get .5uV. AND the UHF transmitters could get really nasty. AND we were thankful for EVERY tenth of a microvolt that we could get. OH Remember the PRogress Line.... and the PRE Progressline and how bout them TPLs (Tolet Paper Lines). I hated the dyno-motors. 73 AC0Y
