Re: Airspy+spyverter vhf unusable

Take a look at this. I guess he's using T adapter "I have two input connectors on the back panel. The first HF puts in the way the SpyVerter converter, the second VHF goes directly to AirSpy. It works great."

How to use it together? There's no switch like ham-it-up upconverter has.

Mirror reception with v3 dongle

Using qfh with lna. Here's an example of mirror reception of 145,8 MHz APRS on 145,8 which interfere with ISS downlink frequency. Second pic is with bandpass filter 137-174 MHz connected. What's wrong with it? http://www.imagehosting.cz/thumbs/clipbojpj.jpg http://www.imagehosting.cz/thumbs/clipbozk...

Re: Meteor M2 interference

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