Weak reception 42-355
#3

Chuck,

Thanks for the pointers. I found an open at pin 4 of the antenna coil (part #5). After I fixed that and repeated the alignment everything on the AM and SW bands seems to work perfectly. There isn't any noticeable difference when I touch the loop antenna.

The coil fix seems to have reduced the FM sensitivity. Before, I was getting five stations all across the band, but now I only get the strongest one. That's OK, because I never expected to pick up modern FM stations on the old pre-war band. Maybe the open coil changed the FM reception in some way. I didn't do the FM alignment because I found the instructions confusing. It says to connect the signal generator to "2nd IF FM input connection." I assume that means the 2nd IF transformer, not tube, but I don't know what the FM input connection is. (Unless maybe it is grid 2 of the 1st 7V7 tube?)

Thanks again. I'm really enjoying this radio.

John Honeycutt
