Michael,
In the past, they operated at :
SNOTEL:
40.530 MHz master station transmit
41.530 MHz
SCAN:
44.20 MHz master station transmit
45.90 MHz
At some point they were all going to switch to:
40.67 MHz master station transmit
41.61 MHz -

So maybe try SCAN at:
41.61 MHz CW.
(Also maybe 45.90 MHz CW if they are still operating there. Not sure
though. I cannot get SCAN from here in the southwest US. Too far away.)
Here are samples of the sound you should be listening for. It is a very
different sound compared to tv transmitter pings.

Please report if you pick up anything. Good luck
