Hi Dave, Wolfgang !

Please have a look at this website :

The Chip-manufacturer claims 10 Bit resolution ENOB (effective number of bits), so the device should be somewhat better than the usual DVB-T sticks at 8 Bits (at more than 10 times the price of those).

Hello Dave,

By coincidence, one of the developers of SDR-play recently asked me if
I'd like to have one of these devices to add support for it. Since I
cannot devote lots of time for it, my suggestion was that one of the
SDR-play developers should write an ExtIO-compatible interface DLL for
it. Most if not all SDR programs support it, for example Winrad, HDSDR,
Spectrum Lab, and possibly many others, so writing such a DLL would make
their radio more useful to many users.
I don't know what happened since then, but maybe there is a
Winrad-compatible "ExtIO"-DLL available already, which you can easily
load in Spectrum Lab as driver for an 'input device'. Just let me know
if you need more information.
It would be interesting to know how the SDR-play compares with other
(more expensive) SDRs. Maybe I will carry one home from the Ham Radio
fair in Friedrichshafen this year...

All the best,
  Wolf .

Dear LF

I have a new toy which I've finished playing with and I want to use it
for some useful purpose. It's an "SDR-Play" USB SDR.

What I'd like to be able to use it for is to replace my old Soft-Rock
SDRs for my LF and MF grabbers.

I can get it to view a slice of the spectrum 500 or 600kHz wide from,
say 50 to 550kHz, then I want to be able to run two instances of
Spectrum Lab (or Argo?) to take grabs of the 136 and 472kHz bands.

But, how do I configure spectrum Lab (or another program) to be able
to do this? I feel awfully out of my depth when I read anything about
setting this sort of thing up so any help in plain language would be

I realise I'll have to pay great attention to the front-end filtering
in order to make the most of the limited resolution of the A/D but
that sort of stuff I can cope with!
