Hello,
?
on December 18th I posted about the damage of my 80 m pa.
A friend in our local club (Franz OE5SFM) made some measurements and?
found out that Q4 and some diodes are damaged (maybe Q6 as well).
?
The cause could be too high voltage on Q4 due to a bad SWR (the abtenna?
went down to ground without me noticing during last QSO the evening before).
?
Franz meant that two additional diodes could have protected Q4.
?
Anyway,? a repair is too much effort (for me) and I will not pursue it further.?
?
Thank you very much anyway, Evan and Aki for your help. Your guess was in the?
right direction.?
?
73, Roland?
