[hpsdr] pico-psu 120 report

[Philip M. Lanese]

Very good Roger -- so can I expect you this weekend to assist in getting my
duplicate combo up and running?
AND also under Linux?  For some reason known only to Wiley Gates my W2K keeps
restarting to never-never land.
You were the first of only 6 contacts I managed to make before giving up in
frustration.

Phil, K3IB

> I used the picopsu-120 with the SDR-1000 and Atlas/Ozy/Janus for the ARRL VHF
contest this weekend.  I powered things up at 9 am Saturday and everything
stayed powered up until 7 pm Sunday when a very active local electrical storm
caused a transient power outage, shortly after I observed lightening occurring
BELOW me down in the valley.  At that point I decided to quit ;)

the picopsu-120 did not feel hot to touch.  I was contesting and not looking for
little spurs on the spectrum display, but I can say that there were no spurs
that affected my SSB operations.  I did not use this combination for CW and
can't say what the result would have been in that sphere.

> The picopsu-120 was a quick way to get up and running, and has the advantage
of taking up zero table-space.  At some point if I ever get around to 'boxing'
the unit I may include a linear supply in the box, but for now this combination
is simple, inexpensive, and compact and so I am using it.  My 'Pandora'
consisted of a piece of duct tape to hold the unit in one place on a corner of
the operating table.  I thought it looked really sharp ;)  Even though there was
absolutely no shielding of the Atlas/Ozy/Janus combo, I had no problems with RF
affecting the Ozy/Janus combo, perhaps because I only put out 180-200 W on 144
MHz and less power on all the other bands.

problems identified.

There is NO perfect solution for everyone, as each of us has different
priorities and resources.  The
> important thing is to power it up and use it in a way that is satisfactory to
you, early and often;  the means of achieving that is secondary.  So this is a
report and and an

combo, and not a recommendation of specifically how to do that.
