Title: UNID 7.228 KHz 0625 UTC Feb, 26, 2022 tone sequence
Post by: DeepBlue on February 26, 2022, 0634 UTC
Hearing a loud series of tones on 7.228 MHz. S9 in Central Ohio on the IC-7300 and 6BTV antenna.  The timing is off on some sections of the sequence which makes me wonder if it isn't encoded in some way.  The sequence of tones does seem to have odd spacing too.  Off air just now at 0632 UTC.

Did a search on the forums and a generic search. Nothing but a few mentions of an Amateur Radio Net.

Without something more to go on, a screen shot of a waterfall, an audio recording, or something like that, the number of possible signals you are describing is quite large.

You are not going to get an answer without more information.

Yep.  I had intended to but wanted to type up the info as quickly as I could.  It may be worth watching the freq off and on to see if it shows up again.

FYI, the /rUkraine sub on Reddit has been posting some actions by Anonymous and others attempting to disrupt various Russian military frequencies and at least one list of military frequencies was published there.  I cannot confirm as I am out of the area and unable to hear any such signals direct and will not be tying up SDRs in the area to listen for some time.

Just checked 7.228. Not present at this time.
