[Milsurplus] Anybody ever played with a FC141-1 CAA fixed tuned single freq HF receiver?

Hi

Why assume the crystal is *above* the RX frequency? 455 + 1241 puts you inside the 1.6 MHz range.

Actually found a manual on Nick's Navyradio site that covered several CAA receivers, and had this one in chapter 13.  It apparently uses solder in coil sets for different freq ranges, and the crystal freq is the Cf + 455KC.  It has a crystal in it, but the nameplate says 1241.875KC which puts it receiving far below the lowest coil set that starts at 1.6Mhz..  Unless somebody was listening a bit off freq to a BC station on 1242.33KC, that crystal might be a red herring.   Of course, the coil  set markings are not visible from the outside in this receiver, but in the manual, they show them clearly marked for Band 3 in this instance.
