USCG Aux HF Freqs

[n2nov]

Has anyone observed any actual HF frequency usage by the USCG Auxiliary recently? I know some may have frequencies in their notes and some may have channel designators. Let's share what we have and match them up.

I'll start things off with some notes:
1 - range from 2 to 23 Mhz
2 - 33 separate frequencies using USB
3 - 8 blocks of frequencies
4 - channel designators are trigraphs (3 characters) - block letter (A-H) / Mhz / channel sequence (A-E)

For example, my notes show 7.736.5Mhz as D7A (block D / 7 Mhz / first freq in block D)

Last night 5253.5 KHz was active with the USCG Auxiliary Pacific Area Contingency Communications Net...

2670khz is always used up in Alaska. It is/was heavily used when that volcano up there was spewing ash into the waterways.
