[hpsdr] Ozy EEPROM

[Ramakrishnan Muthukrishnan]

Hi,

It finally worked and the problem was mainly because of some wierd
vista/.NET issue, unknown to me.

I got the Mercury code upgraded and got it working. Very nice rig.
Thanks to all for the hard work and for giving us a lot of opportunity
for further education.
