I don't claim to be any sort of expert, but on the radio course I took, we
learned that 2182 kHz is "the international distress, safety and calling
frequency for radiotelephony". As far as I can see that is well below 4MHz,
and commonly used even outside Alaska.

Actually you will find that in the USA, 2182 Khz is not used along our
Coasts for the simple reason that it's daytime coverage (Groundwave)
is easily covered by Remote Base VHF Highsite Radio Systems. This is
different then most of the European Countires as they tend to have
significantly less coastline to monitor, and usally it can be done with
just one or two stations in any country. All High Seas Distress Radio
Systems are now based on the IMO GMDSS Convention, which feature
multiple Maritime Radio Frequencies in the HF Band. In the USA 2182.0
Khz isn't even monitored on a regular basis by human ears. For the
North Pacific, 4125.0 Khz is moniotred by human ears, from Kodiak,
Hawii, and Comox BC on a 24/7 basis.
