[Milsurplus] Beacon Band Tuner

[Tom Brent]

Hue:

The tuner in your photo that is marked for use with the ATR-11 appears
identical to the one I have for the AR-15, at least externally. The one I
have uses one each 12SK7 and 12SA7 tubes, indicating RF and
oscillator/mixer stages only. I would assume the output is fed to the 1st
IF stage in the AR-15 receiver or possibly just straight into the antenna
stage. The Amphenol connector on the back of my tuner has the same pin
configuration as front panel connectors on the ATR-11. It seems reasonable
that identical or at least very similar LF tuners could have been used for
both radio sets.
