Hi All;
Before I start to build a Breadboard Oscillator circuit.. I though I would ask --
What steps would Everyone suggest I take in finding and or eliminating where the problem might be ??
By having a checklist I can go thru it and "say" I've done that or I need to do that, or I didn't think of that..
I just want to make sure I have done or tried everything that would logically be done to find the problem..
I have sound going thru the Audio stages and IF going thru the IF stages, and get the output on the speaker from it.. I can pass IF (460KC) thru from the antenna.. And some but not regularly I could get a station to come in.. But, not at present.. When looking at the Oscillator I can get a variable frequency, not necessary the correct one.. But, it did oscillate..
My next step would be to build the front end: Antenna to RF to Oscillator to Mixer circuit on a seperate wooden board.. And subb it in..
What suggestions does everyone have ???
THANK YOU Marty
