As for time-nuts and radio, I think SDR is a great place to tie them
together.

Getting back to the OP, what he was looking for. And SDR has two parts, a
hardware front end and some software. Those two parts can be mostly
independent.

Ability to function as a crude SA.
Not crawling w/ birdies or aliasing issues.
Will run on Win XP.
Demod selecttable for all modes at all frequencies.
In a package, rather than a loose PCB.

Hi John,
I don't think you quite got it yet. All of those types of Dongles
have no frontend filtering and no gain control (AGC). Basically it is a
diode (so to speak) looking at the spectrum from DC to Daylight, even
though they have a limited range. So, yes, there will be birdies and

If it's cheap enough to make disappointment a minor issue - go for it.
There will be spurs at the clock frequency(s) and harmonics there of. At some
