Re: Noise Level K3S Higher with Preamp Off using LoG Antenna

Bob McGraw - K4TAX

Just looking at the block diagram, it appears that the RX ANT  path is the same as the normal receiver path except for a switching point. 

I can't imagine using the preamp on 75M unless your noise floor is less than -130 dBm.
