[UK-CONTEST] maas sps8400 psu

[Ron Pratt]

Hi all.

I am looking for info on the MAAS SP8400 psu I have which has developed a
strange fault. For a few weeks now I have had 

bad interference on 80m, it was particularly bad on the CC on Thursday. It
was still bad the next day so decided to use my small receiver to locate it.
This was on LW fortunately when I switched on and it was totally wiped out
indicating it was very close. Switching of all my equipment in turn only
cured it when I turned of the psu. Scopeing the output showed pulses with
what looks like RF on them even though the volts are correct !

What would be helpfull if anybody knew who the suppliers are and where I
might get it repaired or might even has met this fault before.  It looks
like the current ones from Palstar and Nevada though has meters instead of
digital readout.

I have noticed before the range of knowledge on this reflector so I await in
hope.

 

Thanks
