[Milsurplus] Looking for a Navy ATD Transmitter

[George Babits]

Yup, the TA-12 is something that will do the job just fine.  I had a dozen 
of them (G models) and nobody wanted them at $100.  I kept two for myself 
and gutted the rest.  I have the loading coil too, but I doubt that would be 
needed with an antenna over 2 or 300 feet.  That loading coil was for short 
antennas found on aircraft.  Hope to get mine on the air this winter.

73,

The ATD CRR-52253 came standard with these TUs:
CRR-47208    540-1500 kHz
CRR-47209  1500-3000 kHz
CRR-47210  3000-9050 KHz  (2)


For 200-540 kHz coverage one needs transmitter TU CRR-47207 and antenna TU 
CRR-47206.  These are not rare, but they aren't really common either. 
Finding the transmitter will be a lot easier than finding a CRR-47207.


A T-47 or T-47A/ART-13 with O-16 or O-17 would likely be easier, but 
absolutely mandatory is the CU-25 or CU-32 external PA tank and antenna TU. 
These CUs are not super common.


A Bendix TA-12B, C, or G with MT-53B antenna loading coil is probably the 
easiest  operated, most common, and smallest old military MF transmitter to 
put on 472 kHz.  The MT-53B is nothing but a series indictor, so it is 
easily to substitute.


Good luck.

  Looking for a clean, unhacked

  Navy ATD Transmitter. It should

  have 200 to 540 Kc capability.


  Anyone have one they will want

  to part with ?


  The closer to Tucson, AZ, the better.


  tnx es 73, Dick, W1KSZ
