Even when I listen to QSO's on 80m and 40m?
I'm suspecting of Driver and Finals, because the set
was obviously overcharged (wire replacing the fuse,
transformer and PCB completely burned!) and perhaps
desaligned for 11m...
Since the 6KD6's are original (Toshiba with green
band) and seem to be expensive... I would like to know
if there is some expedite test to check their
I think that the display is not working properly,
since on some band selection the first digits are
overlapping (28 and 29, 14 nd 21) and some are not
showing (3.5 and 7).
Could it be some degradation at old IC's and
transistors or diodes?
What should be tested first here in the counter?
Where could we find the service manual?
Many thanks for your attention
and *** Best Wishes for 2006 ***

Sounds like one of your mixing
oscillators is malfunctioning.
Check the frequency of each of
your oscillators and the output
of your mixers to make sure you
have all the needed frequencies.
