[hpsdr] New HPSDR card for VHF/UHF ?

[ct1izu]

Getting a front end to deal with EU contest levels on 144/432 can be quite a challenge. 

One thought is PENNY style card with a  14 bit AD9739 tx which is then used as a LO in the rx period
 to drive a level 17 diode mixer like a SYM18H. Mixer output would be routed to  Mercury card.

A nice use of a SYM18h is here http://ra3wdk.qrz.ru/tech.htm

G0RUZ and CT1DMK are also looking at ideas here http://g0ruz.com/new/?page_id=57
