[hpsdr] Basic question

[pvharman at arach.net.au]

Hi Steve,

We are actually going down both paths – have a look at the Horton and Phoenix 
projects on the HPSDR Wiki  at 

http://hpsdr.org/wiki/index.php?title=HpsdrWiki:Community_Portal

The reasons for doing Mercury are:

1. To see how good the latest ADCs are in comparison with ‘traditional’ 
analogue  SDR circuitry. 

2. The technical reason is ‘because it’s there’ and we like living on the 
leading edge (or in some cases the  bleeding edge) of new technology!

3. Long term I expect that the sound card approach to SDR will make way to 
direct ADC (and DAC) at the antenna. We want to be well ahead of the rest of 
the field when that happens. 

4. I get way too much sleep already.

Phil
