4/4/25:
It’s arrived! And, it works! The radio was removed from a boat many years ago and put into storage. The owner very kindly gave it to me, for which I’m most appreciative.
Check this page for updates and more photos.
Long Wave 170-350 kHz
Navigation 300-535 kHz
Medium Wave 700-1650 kHz
Short Wave 1600-4200 kHz
23 crystal controlled frequencies (18 fitted).
SSB reception:
The receiver employs a product detector rather than a simple BFO. When switched to SSB, the receiver will resolve USB only. There is no LSB/USB switch. I believe there’s a modification for this but I’m not bothered as I’m only interested in commercial transmissions rather than amateur.
The radio is an excellent condition for its age. Watch the video at the bottom of this page. The dial and meter bulbs need replacing. The pots and switches need cleaning but the radio is working extremely well. Radio Guernsey is very strong on 1116 KHz. Surprisingly, there’s no RF amplifier stage. I can’t think why it was deemed unnecessary.

I’ve looked up the frequencies and the allocations I’ve found are shown below.

This frequency was allocated to Humber Radio, now closed down. But I’ve heard weather and navigation warnings on 1925KHz.
