[hpsdr] ANAN-100 sometimes no TX, after upgrade to 2.9b/3.0 and 3.2.19

[Mike Sch. (IMAP Acct.)]

Very interesting, Bill!

I can surely have a look at the DC power feed!  I do recall that the 
rather "strange looking" power connector that I got with my ANAN-100 was 
falling apart.  I tie-wrapped and glued the connector.  Maybe this is my 
trouble?  Maybe, maybe not, as I have just "downgraded" to firmware 2.7 
from 3.0, and now the radio is working perfectly, so far.  (The radio is 
in a stable position, never moved in any way.) As I had mentioned, I had 
NOT restarted the PSDR app; -I just dumped the 2.7 firmware in, and ran 
the radio, where I found it to be as solid and stable as I had 
experienced before I did the upgrades on Sunday.

What was "lost" after I upgraded has now returned when I dropped back to 
2.7 from 3.0, just as seamlessly as it had gone away..!
