That will be 472 to 479 kHz, 630 meters.

My best VLF/LF/MF receiver is a R-1134B/WRR-3 (14 to 600 kHz, all vacuum tubes).  That's the same model that was on almost all USN surface vessels in the 1960s to 1980s that was used for, among other things, keeping watch on 500 kHz.  We had one on board SSBN-629, although submarines were not required to watch 500 kHz...and it was not used for the normal submarine VLF reception.

I have a T-588/ART-33 that was used on some USCG aircraft to provide MF Morse maritime band transmission.  It is crystal-controlled for all the standard merchant vessel MF Morse channels from 410 to 535 kHz.  It is local control only, probably about 40 watts output, 400 Hz AC power (unfortunately).  It uses a remote-operated trailing-wire antenna.  I don't know what receiver the USCG used with the AN/ART-33.  They could have done reasonably well with a R-23A/ARC-5.  Before I found the AN/ART-33, I was unaware that any USCG aircraft had MF Morse capability.

I preferred listening to the maritime MF Morse band more than to any other frequency segment.  I miss it greatly...especially 500 kHz at night.
