[ICOM] PW1 REVISION

[Adam Farson]

Hi Max,

If you could do me a favour and let me have a link to the technical note, or
send me a PDF of it, I shall place it on the Icom FAQ website.

Cheers for now, 73,
Adam VA7OJ/AB4OJ

Just to let you know that, after a lot of failure at least here in Europe,
ICOM Japan released a technical note about the PW1. Some equipment suffered
of mosfet's burning and the engineers assert it depends from a RF feedback
in the LPF board. In some circumstances the RF can produce a false reading
by the logic circuit that switch some relays on or off in the wrong way.
This produce high SWR on the PA module and the consequent burning.
The modification consist in soldering some capacitors on the LPF board.
Unfortunately I've just seen the message from ICOM Japan but I wasn't able
to pick up a copy or take in-deep note.
