[Premium-Rx] software based IF spectrum monitor/panadapter?

[Jerry K]

The Brit version is at
http://www.picotech.com/picoscope-3000.html?source=featured-PS3K. Looks
pretty slick, but at 400 British Pounds (about $713) for the 50 MHz version
it's not exactly cheap. 100 MHz version is 600 ($1070), 200 MHz is 800
pounds ($1425). I haven't seen a USA manufactured version of the same thing,
although there might be one. This looks like a ripe field for the Chinese to
plow. I'm surprised Hong Kong doesn't already have a $150 clone on Ebay.
I've seen some of the HK true RMS DVM's ($20-$40 on the web) and they seem
to be pretty good meters. Hard to argue with a nice true RMS meter that
works for that price, and if it breaks or you blow it up, you can simply
trash can it and buy another one without remorse. Another sad but true story
in the world of electronics manufacturing.

I had to cough up $500+ for my HP-141T a couple of years ago, and although I
like it a lot, it weighs a ton and takes up a lot of bench space. A little
black box interface unit and my laptop would make much more sense to me. If
I had seen the Picotech first, I might have bit the bullet on the extra $200
and bought it instead.

This discussion got me ta thinkin...

Anyone know of a spectrum analyzer software with some kind of ADC board (ie
higher freq than audio board) that can be connected to the IF out on a
receiver (say 455)??  I guess short of buying an expensive
pc-o;scope/spectrum analyzer..something simpler, you know, poor man's
pc-panadapter
