Re: Noise in receivers
VERY interesting David. I guess its like the audio quality in TV's.... gets least design thought...the front end FET indeed is given the same voltage on G2 as the later I.F devices. I guess its a case of... if it works.. ish..get on with designing something else... its only Amateur product.
To compare two receivers (FRG7's)with decidedly different apparent gains, is to disconnect the AGC and check each stage to see where things change appreciably, or is it a subtle change which is accumulative. I then wonder if the "Good" receiver has been "tweeked" and I am looking the wrong way.
Still it keeps me off the streets.
