Jamming on PSK
I was on 15m PSK31 and in the process of calling PY3ED when a vicious jamming signal started up.
|Jamming on 21MHz|
As you can see, it did a good job of obliterating all signals. It seemed to be centered around 21.070MHz and extended for 50kHz or so in either direction.
I don’t know how long it stayed on for because it was lunch time so I went to have something to eat. When I came back the interfering signal had gone.
Was it something local to me or has anyone else seen it?
This might sound weird, but could it have been from the Sun? Seems to me over the years that I read about a burst in the 15 meter band range. I will do some more research…
73…hope you are doing better and glad you are still blogging
No it’s QRM and I got it also. 21.130 also seems to be to be a place to jam or hold open until sked time. TOO BAD. But who ever it is must have on hell of a set of finals.
I myself was on 15 meters on PSK and saw and heard the same thing this morning around 14:15 utc every signal was completely blocked out. I only stayed around a short time before shutting down my equipment was strange I am in Florida.
I’d bet it’s OTH radar.
