Meteor M2 interference

Post by Giftmacher » Sat Sep 10, 2016 10:40 am

Can anyone identify signals jamming M2 satellite? It broadcasting on 137.929 and
137.836 MHz, can't get clear image.

Got a screenshot of the interference? Most likely it will be overload from broadcast FM which you can fix with a BCB filter.

It doesn't seem to be FM radio, I would say it's aircraft communication.

Looks like interference from a very strong signal somewhere. Your options are:

1) Turn down the RF gain until the interference no longer shows up
2) Get a filter to block the offending signal
3) Buy a higher end more costly SDR like an SDRplay or Airspy
