Back around 1960, the Navy modernized it's shipboard radio shack with
R-390's, CV-591A/URR's, AN/WRR-2's etc. But they still needed an LF receiver
that would cover 500 kc for maritime distress requirements, plus be
available for LF tactical freqs. The AN/WRR-3's were the answer. The LF/MF
transmitter that matched up with it was the AN/WRT-1. HF transmit was
covered by the AN/WRT-2's and AN/URC-32's. We had one pair of LF rigs
(AN/WRR-3 and AN/WRT-1), and I think they sat on 500 kc the entire four
years I was aboard my first ship. I suppose when they were scrapped they
were still tuned up on 500 kc. In the entire time I never heard a signal on
the receiver, although I suppose there might have been some. They were very
deluxe and impressive looking receivers, much like the AN/WRR-2's, and I'm
sure cost the taxpayers a bundle.
