Can anyone offer me some advice on the FL2100Z please?
Ive recently bought one for a silly price (due to the fact it wasn't working
and had many faults).
I've now managed to get down to two problems, any advice/assistance would be
much appreciated. Replies direct to
carr.n@runshaw.ac.uk please.
(1) I have a bad i/p match on 10/12/15/20m the other bands are good. How
do I adjust the input matching? A quick look inside the back panel cut out,
suggests the band switch L.C. tuning are preset values with no trimmers, Am
I missing something? (I don't have a cct diagram)
(2) Someone has told me they think the following is a know problem, and
this is the place to find the answer, here goes.....
No matter how well the amp tunes up on a particular band (and all bands are
affected) after a short period of time the o/p is nil and I have to
completely retune, for example, tune up to 400w on 160m, leave things
running on stby, come back 15 mins later and o/p is nil. a retune brings it
back up, but plate and load and in completely different positions. Ive heard
there's a capacitor somewhere thats the culprit????
73 and hope to hear from someone de Neil G0JHC.
