EXPERT 1K-FA and the MODIFICATION
For the last 7 years I used the Expert 1K-FA
Now after 7 years it's time for a relay modification.
I did get problems with the receiving signals because of 2 outworm relays!
We must do a correct dismantling of the PA (power amplifier) board.
.After that remove the old relays
Powerboard is out Pff you see the 6 transistors helping me working the world HI
It's a lot of work.
Thanks to PA0JEN for the modification and Bob PB5X for the connection.
Left you see the black ( old ) relays, right the 2 white Finder relays.
Nowadays Expert only use Finder relays because of the much better quality!
All working fine again now, happy with the result of this modification.
NOW I USE THE EXPERT 1.3 K - FA
Fully automatic and good for up to 1KW
