[ICOM] FIXING PW1

[Massimo 'Max' MUCCI - I8NHJ]

Ciao Adam
yes, I checked it with and without ATU. No difference.
I can say what the condition of the failure was. I was
running 80 some days ago with no problems. I run some CQWW
on 14 yesterday with no problems too.

Changed to 80 for a while and I discovered the failure.
Thanks, I already download the manual.

I suspect some trouble with the selection relay, maybe there
is just 1 relay for the three bands? No time to look at the
schematics yet.

AF> Hello folks,
AF> My PW1 need to be fixed again...

AF> At present time I get no power at all on 80, 40 and 30 bands, while the unit

AF> The remote control prom the PROIII runs flatly and I've done a CPU reset

AF> I've not yet looked inside but I smell some smoke scent...

AF> Any suggestion from the list?
