Hearing several stations checking in with net control station NCS042 and NCS042 requesting any and all check-ins and relays from other nets. SHARES also heard on 6910 kHz USB and 6765 kHz USB. At 1644 UTC, NCS042 doing another radio check and requesting "any station any region" check in to net.
SHARES NORTH net happening at the same time (these are weekly nets) on 6765 USB. Didn't hear anything on 6910 USB or 7320 USB but the band conditions have been less-than-great so its possible I just wasn't hearing them.
Other SHARES frequencies (according to my book):
SHARES/FEMA-1 (Night): 5211 kHz USB
SHARES/FEMA-2: 10493 kHz USB
SHARES/FEMA-3 (Day): 14597 kHz USB
SHARES Night: 5236 kHz USB
SHARES Day: 14396.5 kHz USB
SHARES Central: 6910 kHz USB
SHARES Southwest: 7320 kHz USB
SHARES Northeast: 6845 kHz USB
SHARES North: 6765 kHz USB
Plus MARS "Disaster Net", FEMA, SECURE, and Civil Air Patrol HF SSB frequencies, including 7615 kHz USB (CAP Nationwide "CAP NHQ" net) - CAP has hundreds of other frequencies including ALE capability. I mention them here because I've heard CAP callsigns on several SHARES nets in the past, indicating their participation in SHARES radio checks and programming of SHARES frequencies in CAP radios. I can also confirm that CAP includes FEMA-1 5211 kHz USB and FEMA-2 10493 kHz USB in their radio programming for direct communications with FEMA networks.
MARS Disaster Nets 6912.5 kHz USB, 7403.5 kHz USB, 13510 kHz USB, 13997.5 kHz USB, 14390 kHz USB
Missing SHARES West (I assume there's a SHARES West) frequency - if somebody has it I'd like to add it to my listing
