Quick update and more interesting info.
As mentioned I have been running this 80 in my shop down in the basement, with a 20 ft antenna and ground to a copper pipe. I have been getting in AM 1370, 1230 anything high end of the dial coming in STRONG and great but 800 and 760 (stations usually equal to 1370) where fairly weak, like 60%.
So curious about my correct IF I took the radio to check the LO with the only digital radio I have in my car out in the garage. So I set the 80 next to the car antenna, hook up the 80 antenna (but with NO ground) and turn it on AM 800 so I can get a nice 450 or 460 above that easily. Well BLOW ME OVER....that AM 800 was SOOOO strong and clear as was 760 it knocked my socks off!! I go to try 1370 and 1230 and ffffftttttt NOTHING....or almost nothing. I'll be d**ned! LOL....
Long short my LO seems to be 460 and I take the radio back down to the basement and the previous set up and voila it is back to strong on 1370 and weak ish on 800 again.
So any ideas? Is this just position and placement of the antenna? Antenna length? Could it be something with the antenna coil I re-wound? or is it just the nature of the beast being a 4 tube regen.
Looks like the fiddling around continues!
