Re: Only noise when connected to the antenna #v6

More than likely, your IF oscillator frequency is off and the Xtal filter attenuates the incoming signals as a result. Try calibrating the BFO oscillator. 73's Ron N7FTZ On Mon, Mar 2, 2020 at 3:03 PM Jonathan Kayne, KM4CFT <jzkmath@...> wrote: It seems that somehow there is a bunch of noise making it into the radio. Just running it through the 1st conversion seems to bring the noise floor up enough for any reasonable signal to have adverse affects on the performance as seen by these two pictures! This was at the antenna connection so somehow noise from the 1st conversion is bleeding into the circuit making it too noisy to use.? |
