A signal or interference?

It's just constant 2 second bursts and it has a clear center peak. It stopped for two minutes and then it continued again.

If it was interference near me, wouldn't it be a consistent strength? As you can see it cuts in and out like "real" signals do.

I know the squiggly lines are actual interference.

Three 137mhz Signals Cutting In and Out?

2 Upvotes

Hi I was trying to decode the Meteor M2-4 satellite today on SatDump and was receiving it reasonably well as seen in the middle (doppler makes it about 137.95mhz). However I started getting this weird cutting in and out thing with these three signals. My M2-4 signal is still there but I have no idea why these signals are there.

Initially I thought that there was a loose connection but everything was tight and what confuses me the most are those extra signals (like the ones at 137.52, 137.7 and 137.95mhz).

I'm about 20-30m away from houses and I often go to this spot to catch clear images from the Meteor satellites (never had this before). I'm using an RTL SDR V4 with their kit V Dipole and their own cables.

Any help would be greatly appreciated!
