[time-nuts] SDR Radio Opinion ?

[John Ackermann]

The DTV dongles are very cute and really great educational devices, but 
one thing to keep in mind is that they have 8 bit A/D converters and 
consequently pretty limited dynamic range.  And the frequency 
accuracy/stability is pretty horrific for anyone on this list. :-)

I keep one in my laptop bag to use with Gnuradio when I'm traveling.

> Google DVB-T and RTL2832.  I bought a device about some months ago for about $20.  It does actually work as advertised, though this one looks nicer than the one I got.  Apparently the guy who was writing the linux driver for these (Antti Polisaari of Finland) noticed a feature that allowed it to be turned into a broadband receiver.  It can be commanded to output an 8 bit I/Q stream at up to 2,000,000 (more actually) samples per second from 64MHz to around 1.7GHz.   There is an article about them in the Jan 2013 QST.  There's at least one guy on ebay selling HF converters for them.
