Hi All;
THANK YOU Brenda Ann, that is exactly what I need to know.. So I have it correct.. Sorry about the confusion about the 1010KC, that is the Frequency that I have my Oscillator set to, If my math is correct..
1010KC - 460KC (IF Frequency) == 600KC.. or 600KC + 460KC = 1010 KC.. Right now I am persuing why I am NOT getting a louder tone from the Audio Amplifier, than I am..
I found out why my audio wouldn't go thru, I had the "Tone Control" on the wrong setting, the tone control was filtering out the Audio "HUM" I was sending to the Radio..
I can now send from my 1st IF all the way thru the Radio, but not a signal fed from the "RF" Grid of the mixer Tube, it comes thru but very weak..
THANK YOU Marty
