[Elecraft] K2 Repairs on hold while i fix my K3 12V ERR - now Fixed

[Clifford Hynds]

Hi Fred and group,

Well yes I suppose it could be called a disease Hi!

I actually started not long ago when an unbuilt K2 with SSB kit was up for
sale and i felt I wanted to build something for a change, It is complete
but have some kind of transmit problem where the power drops off 15W at 80M
and progressively drops off to 10M. Strange !

Receiver side seems fine.

Have Gone over the adjustments to no avail suspect the Transmit Mixer
output may be low.

Anyway later on I bought the following also second hand

K3,P3 and KPA500 came up second hand on our VK classified site.

I've owned a lot of tranceivers over the years but the Elecraft gear id
different somehow, no small p[art to the support and enthusiasm of the
owners and company. Also like the idea of standard type connectors not
proprietory . Good old DB9's etc.
