Not sure what it's called, I've been searching with various syntax, but not finding it. I saw a mod somewhere for the RCI 2950 ilk that would stop the "drop out/muting" between channels as you spin the knob. Is anyone familiar with that mod?
!!!???Also found c89 & c90 backwards from the factory (bfo & if injection ratio)
!!!???
Yeah, I saw a post about this and realized I've corrected this in a bunch of old Heathkit HW-101 rigs over the years. Sounds like an agc problem, but the bfo energy should be 3-5 times that of the I.F. level in the detector. A lot of HW-101's will be more like 1:1, and it makes SSB sound horrible and metallic, almost like an AGC problem. Increase the bfo injection level and it really cleans up the detected signal. The post I saw about the RCI rigs stated that C89 was supposed to be 5pf, c90 was 10pf...but they were reversed and the BFO level was too low. I checked mine, sure enough
tweek,
glad i could be of some help.
looks like you're no slouch when it comes to radio knowledge!
we can always use people around here that can answer questions and teach.
we also love it when people with experience post up the mods that they like to do.
hope to see you around soon!
