Thanks Sig, for the info on the Belka and IQ output. That's a really nice looking grab. I'll have to give it a go also with some QRSS signals. I took the Belka mobile, and it hears the ignition noise in my truck pretty well! :-)

Hooked to a Hustler mobile whip I found that it would make a decent ham receiver for casual CW contacts on 40.  There's really not enough audio to overcome background noise with the built in speaker but it works great with earbuds.

Will see how stable it is during some QRSS grabs

I picked up a old Larsen / Motorola mag mount and a 32 inch unloaded antenna element on the weekend at the surplus store. I am going to test it for mobile operation. All I have to do is change the connector on the coax to a BNC.

I am good for audio. The Jeep's sound system has an external mini jack input so the Belka is loud and clear over 6 speakers. You can get a nice battery operated amplified speaker for the Belka. I use my HP portable speakers with mine.

Interesting results, thanks for sharing. I've had no opportunity for testing (distracted by other projects) but will follow up. One requirement is a stereo mic or line input to the PC - I don't have anything to hand yet.
