Hiya Sam, I had one of these, I am sure the FM pot is on the 'local'
board, which is the one with the patch/ptt/CAT sockets on. VR02 I am
sure, and it feeds the fm af amp transistor, q2008. As for the power
control, they are very 'jumpy', all on or off, and very narrow over the
operating range, sure yours is just as they are. I also still have the
mobile mount for it in the loft, I think!!!!!!!!

Hi Fred...


Ah, never mind then, I'll have to live with it (well not me, I'm asking on
behalf of a friend).

Any ideas about the meter though, that needs re-calibrating.

Never had to tweak that one Sam. There is a preset near the meter
driver circuit, (An6552, Q51, on the R.F. board.) That may be the one.
There is a 'pot' to set the FSD of the meter on Tx (for SWR forward
reading, obviously you set it to full scale, then set the swr switch to
reverse.) It is not that this control has been set too far up?? (Its on
the back of the unit, under the antenna socket, marked 'fwd set'?)
Best of luck, mate, I have got a few bits of cct diagrams if you are
really stuck, and may help....
