[hpsdr] Hermes check out

[John Westmoreland]

Phil,

Hi!  Sounds like you are having some fun.

Just a suggestion - I have one of those IR Temp 'Guns' that I am quite fond
of.  It is very accurate.  Here's the URL of an example:

When you do a lot of bring-up - these pay for themselves pretty quickly.  I
hope you haven't sustained any injuries.

73's,
John
