Now that is interesting! As i was posting my just previous post on the GRR-5,
it did occur to me that the air-alert use does not adequately explain the higher
HF range, say the range above about 10 MHz.
Perhaps this kinda parallels the Navy's RBS. It was apparently intended for 
some kind of alert/ monitoring use, but tunes up to 20 MHz. It was also,
we have seen, more often apparently just used as a secondary comm 
receiver. I dunno about the GRR-5 for sure, but the RBS drift and tuning
speed issues mean you do not want to leave it unattended on any freuquency
higher than about 6 MHz.
