Title: Channel Marker on 14.317?
Post by: KM0NAS on November 13, 2020, 2019 UTC
Any else hearing a repeated beeping on 14.317 mhz?

I am hearing it at 20:18 UTC. (Update: started to fade about 20:50 and by 20:51 UTC was no longer audible or had stopped)

Sounds a bit like a channel marker? Not familiar with any that would be on this frequency.

Just a repeating tone over and over. About 1 sec on 1 sec off. Seems to repeat every minute. There is a slight pause once per minute. 37 pips per min.

Strong beacon signal. Is it still there?

No, this was back in November. I could hear it for about 30 minutes and then it faded out.

Signal is audible behind a Parks on the Air activation

i tried to get a location for the signal and was able to hear it on several SDRs loudly in Canada.
It was audible on VE6ARS and VE6JY. I was able to faintly hear it on the Kiwi SDR in Minneapolis but aside from those three I was unable to hear it in the dozen others I tried around the country and around the world. As I noted, VERY loud in Calgary.

Signal was first drown out by QRM as I tried to find a third station for DToA but seems to have stopped before 17:57 UTC.

I was able to generate this heat map with two stations but take it with a HUGE grain of salt. There was QRM.

Here is a screen capture from one of the Calgary SDRs.
