Many people on Internet are talking and documenting "GNU radio" ability to create a SDR out of a USB DVB-T TV tuner. [I apologise for too many acronyms in one sentence.]
A 20US$ device (Ezcap EZTV668 in my case) is supposed to tune, display and decode transmissions between 65 and 1700 MHz. Sampling resolution is only 8-bit and there is no front-end filtering for this direct conversion receiver (can be added externally, of course), but this will let me have a peek at 23cm band.
Also it could be useful as a poor man's spectrum analyzer in my lab.
Who knows? Time - and experimentation - will tell (me).
Well, first it has to come from Far East.
