1st thanks everyone for the help.Yes, have had bad solder joints, and yes my gen is off. I have a DVM with a freq counter so I have been checking it every time. So I got back 810 but thats it.
I HAVE A DEFINITE PROBLEM IN ONE SECTION. WHO CAN HELP??
2nd step on tuning, 18Mc on SW. My gen can do 15M. I get it on another radio that has SW. Nice loud wine from across the work bench. HERE IS THE PROBLEM. I CAN get that signal on the 40-180 at 15M but it is soooo weak. I literally hang the signal generator's loop antenna on the SW antenna on the 40-180. I try to adjust the 21A tuning condenser like directions say, tune to second peak. I AM LUCK if I get the first Peak in weak with volume all the way up. THIS I THINK IS MY PROBLEM. What gives?????
NO second peak, first one weak with antenna right on radio antenna.
I scrubbed all condensors, checked all new wires, caps are good, resistors are good, right up to the 1232 tube. CHecked for continuity at band switch, checked for ground on chassis to variable tuning condensor, good. Wires from tuning condensor to small coil in chassis good. What am I missing????
Get 1st step in tuning good. 455kc, 2nd IF can peaks, 1st IF can also has peak on 30, and 30B really makes little difference.
Swapped out 7C6 and 7B7 and 1232 NO difference. 7B7 swap made 810 quite again so switched it back to original.
I also swapped in new wire for SW antenna above chassis in case.
STUCK STUCK STUCK, NO second peak at 15Mc on SW band. WHat gives? thank you for any help. Joe
