The QRM (interference) that came... and WENT! :D

[Macavity]

Just a bit of random / trivial good news... I thought I'd share! 🥳



Not sure what the heck this was... but ^^^ QRM (interference) was pretty
much "taking out" aircraft band... Upto and including 136MHz satellite(?)
for about a week. 🤬 Then, just mysteriously as it came, it dissappeared! 😀

But I was a bit intrigued... The spacing of the "comb" peaks is ~28kHz ?!? 🤔
Just wondering if anyone ELSE had ever seen such a thing?

P.S. The following has "infested" the 15m amateur band for as long as...  🙄



</wibble> 🥳

Have seen this comb effect on various bands but cannot pin point what does it.

Normally it does not stop operations, as I run mainly digital modes it's not a problem.

I have just found out I have a wide band hash on 2metres but it's mainly to the SE.

Found out leaky USB leads can give this type of interference.

Also checkout any wall warts, some can be quite filthy.
