[hpsdr] power supply

[Eric Ellison]

Hi Joe/Ray!

I believe that the only problems we have heard about in the past have been
the -12 v supply, which (correct me if I am wrong) is only used currently on
Janus. I believe from the past posts that there is enough power on the other
lines to handle what is in production, or near production. Tests so far have
shown that the unit is pretty quiet. Course we don't have Merc or Horton yet
to really give us a new baseline for ears, but I think Merc is close!

Fantastic on the pictures and manual. For ALL you artisans out there
packaging your projects PLEASE, PLEASE give us some pictures! Put them up on
HamSDR and post links here so we can view your craftsmanship!

Thanks!
Eric

Ray,
I just installed the 120-WI-25 in my setup here; although I am only using
it for the janus/ozy. I can say that I am well pleased with what I have. I
just finished putting the SDR 1000 with an SDR IQ as a separate receiver
(independent or it can use the same antenna as the SDR 1000); Janus/ozy;
XG2 for (alignment); poor man's UCB; 2 relay control boards; all into a
stand alone cabinet. The 2nd receiver (SDR IQ) and "poor man's UCB are in
the cabinet with the SDR 1000 which is housed in computer tower cabinet
along with the main control board and janus/ozy with the alignment board
(XG2). I did take pictures at different times; I am going to put a manual
together along with schematics. I'm sorry for getting long winded but I
have been working on this quite a while and am very pleased with the
results. I did work also with the antenna connections to the rig that
allow a separate receive antenna as well as a loop back option to allow
the 2nd receiver to use the same antenna as the main transceiver; this is
where a lot of the relay logic came into play by muting and isolating the
2nd receiver when transmitting. Anyway, the pico supply does a good job
here.
