Naively, I've just had a look to see what RS Components
do in the way of ADCs... and found that there's quite a
few available with sample rates
in the region of 10MSPS for around UKP20 to UKP30 and
some with 20MSPS+ for a little more (around UKP40) for
single units. Would it not be possible to come up with
a cheap alternative to the Measurement
Computing board? I assume the minimum spec necessary
with an I/F of 5.75MHz is 11.5MSPS?
>>Yes for sure! Contact David Emory, address@hidden
He has some ideas as to this!
Just a thought, which I'll look into further, but
wondered if anyone had considered this? I know it could
get 'interesting' designing such
high-speed digital circuits... but I've got a
Wavefinder Digital Radio in front of me which squirts a
considerable amount of data down the USB
port so it can't be THAT difficult. Has anyone else
considered this previously?
>>Yes! Vladimir Dergachev is the creator of
SR-1/Software Radio: This is a project to create
a software radio device that uses USB-2.0 to deliver
raw data. Check out the link below:

Perhaps as a starting point some lower-speed stuff
could be done, if we got a lower I/F than the cable TV
tuner, with lower bandwidth, we'd need a
correspondingly lower ADC (maybe even something
reasonably cheap off-the-shelf?) which would allow
those not able/willing to get the Measurement Computing
board to get into wide-band-ish stuff (for examaple, be
able to play two FM stations, provided they were much
closer to each other).
