[hpsdr] Angelia_v3.7 firmware package

[Joe Martin K5SO]

All, 

Angelia_v3.7 firmware package download is available from

http://k5so.com/HPSDR_downloads.html

This version of firmware fixes a bug in Angelia_v3.6 that prevented ADC2 overflow status from performing correctly.  

It is my expectation that Abhi will post the new Angelia firmware version to his Apache Labs website as soon as he is able to do so.  

Thanks to Ton PA0TBR for alerting me to the ADC2 issue.  

73,  Joe K5SO
