[Boatanchors] BC-639 Military Receiver

[Joe Walden]

Hello again,from w5jdy in Okla.   I have completed restoration (all caps and
realignment) of an old BC-639 Military AM Receiver.   It tunes from 100mc to
155mc  It is working quite well with about 1 microvolt sensitivity but there
is a lot of noise Not in the radio but with the antenna connected.  I saw a
BC-639 Radio many years ago that had a 6H6 noise limiter built in it. It was
under the chassis,it was original and came from the military that way. I
would like to find a schematic of that model radio. I will build a noise
limiter in the one I have. Kind of stupid aint it?. The one I saw was
exactly the same as the BC-639 I have and had the schematic with the noise
limiter in the cover.  Just re-inventing the wheel in Okla. Joe
