Hi,

My RCH is probably a backup comm rx, not a morale entertainment set, since it
unfortunately sacrifices the AM BC band to include two LW bands, as for marine
communications. It does provide for feeding a second audio source into its
output stage; unclear what that was used for. The audio output is a single 6F6
or 6V6 or the like, so this RX would not be driving speakers all over the ship.

You can see one installed in a Mackay communications console in the
4th ed. of THe Radio Manual by Sterling & Monroe, 1950. Pages 511 to
553 are devoted to this console, including a fold-out schematic of the
Scott receiver itself (called an SLR-F). It was paired with a Mackay
128AV (15 - 650kHz, battery-powered)

Scott made a big deal of low-radiation receivers and German
direction-finding, but it's far more likely that the low radiation was
only to avoid interference with other receivers on the ship. It's a
very crowded RF environment.

I had an SLR12 once and its dial-drive mechanism was sluggish, not
a set you'd want for band-cruising. They were after all meant to be
left in one position and not re-tuned often. The geared dial on an
RCH works like a dream, in comparison.
