Philco 37-60: Opened Antenna Transformer/Coil - Repaired
#4

Hey hey, the coil is done. I installed it, reassembled the radio and it plays. After an alignment, I'm picking up stations from 1600 down to 700 khz without an antenna, so sensitivity and selectivity is good. But, I'm ran into an issue during the alignment. I begin to loose signal right around 700 khz. I can't hear KFI 640 and motorboating begins softly around 600khz and roaring when it gets to the lower end.

The other problem is howling around 7mhz on SW. First encounter this during alignment.

I would appreciate any suggestions. I'll probably go over the work my colleague did on this radio. There are a couple of original micas still in the radio that needs to be checked.
