[hpsdr] Issues with upgrade to latest firmware

[george byrkit]

Dear All,

I upgraded my mercury and Ozy to the latest firmware, with PowerSDR also
being updated with wisdom and database files cleared out, per instructions.

I was one who couldn't use Mercury at 192k and 2048 buffer.  Now those
settings worked, but all settings were plagued with Mercury relay chatter
and noise on the RX signal, exactly as others have described.

As I have 3 atlas, 2 mercury and 2 ozy, I first tried all atlas boards with
no change in results.  Then I tried the other mercury board with no change
in results.

Then I changed the Ozy board to the second Ozy board that I had and the
problem(s) went away!  Super quiet and clean audio.  No Mercury relay
chatter.  No audio glitches

Then I substituted back the original mercury and atlas boards, with the
system staying 'proper', as long as that second Ozy board was the one used.

The Ozy that works is SN TZ0Z1-077.  The Ozy that is associated with the
relay chattering and audio glitches is TX0Z1-388.

Is anyone interested in investigating this Ozy board that seems to be the
crux of the problems?  If so, I could provide it to you for your
investigations...

73,
George K9TRV
