Utility / Re: SHARES North Net 6965 USB 0053 UTC 10 November 2023

« on: November 21, 2023, 0013 UTC »

This is a FEMA network. Net control is NNA5HF.

I tuned in to casual conversation about property drainage before officially seeking check-ins, then having heard a few, then sent digital traffic. Some traffic or other digital transmissions followed. After the initial flurry of activity, there was a lot of dead air (several minutes at a time) between net control transmissions and I did not stay with it.

Recording, including digital traffic: https://voca.ro/146vc7jT8ims

More info on SHARES: https://www.cisa.gov/resources-tools/programs/shared-resources-shares-high-frequency-hf-radio-program

Heard on the K1VL SDR in Vermont, USA.

---
SHARES is actually a NCC (National Coordinating Center for Communications) program, not a FEMA net, although some FEMA stations do participate. The frequency should also be 6765.0, not 6965.0 & the digital mode heard is MT63-1KL.

I had USCG cutter Tahoma working COMMCOM on 14950.2 USB a few days ago.

The actual frequency is 14950.2 (USB) & it's the US Coast Guard.

6910.0 is used by both US Army MARS (USB voice, ALE & 110A encrypted data) & the NCC SHARES program (USB voice, Olivia & MT63-1KL data).

Utility / Re: UNID 16011 USB ALE Net 1524 UTC 14 DEC 2022

I've only ever heard the growl come from airborne units tuning up. Sounds (pun intended) like they're testing interagency linking presumably for continuity of government in case of the Pocalypse.

61ZB7 is always an Airborne Command Post. Whether it's an E-4B or E-6B, I haven't a clue.

This is the FEMA DACN (Department & Agency Continuity  Network) & it's active in the third week of each month when the first week starts no later than a Tuesday. In December, the net kicked off a week early, presumably because of the holidays. In January of 2023, exercise dates should be on the 18th & 19th.

Notes: (1) An interesting observation. I can hear who I believe is 1BGQY and 61ZB7's antenna tuner tune up prior to transmission. This is odd as ALE stations should be using fast tune antenna tuner units (ATU) with memory. Sounds like a Collins ATU. (2) Thus far, no analogue traffic has been observed on this net.

61ZB7 is a STRATCOM Airborne Command Post. The same tune up "growl" can be heard on the HFGCS.

Clear voice transmissions are rare, but have been heard. In those instances, tactical call signs have been used, however, in the last clear voice I heard, the ALE address was used as the call.

Not sure if this is an intentional frequency, but I've caught several test EAMs on 7000 USB the past few days.

That was a US Navy station participating in a quarterly exercise.

« on: May 12, 2022, 0210 UTC »

Over modulated (here) OM/YL giving phonetic terms (Oscar, Foxtrot) for stretches of time.  Pauses and starts again.  Can not decipher most of words spoken.

-----
That was a USB signal from a USN station on 6988.0 with a exercise EAM.

Are these typical USN EAM frequencies? I'm not familiar with them.
-----
No, they're just used in specific exercises.

HF VARA again. After linking several modulation methods are used to pass traffic.

That looks & sounds like a 500 Hz VARA transmission, plus 6775.0 USB is a known frequency carrying HF VARA. In addition to 6775.0, you can find HF VARA on 3391.0, 4560.0, 4906.0, 7860,0, 9217.0 & 10267.0, all USB.

Both the web site and my login work fine. From past experience, I do know that their Internet hosting occasionally goes funny on them and you have to wait for them to reset whatever causes the issue.

I can get to the site just fine, but I can't check into my account. I also can't register a new account, so obviously, something is wrong there.
