I am looking for some experience/hint on the following
FT-1000D problem, which already occurred twice in my
- power indication low (at 50W) even though the output
is ok (200W) as checked with an external power meter
- SWR indication high (abt 1:10) even though the real
SWR into the dummy load is 1:1
- tuner not functioning "HI-SWR"
first time this happened it also (might have) killed the
final transistors, anyway they were replaced,
second time "only" the diodes in the power and SWR sensing
circuitry and one relay in the LP-unit were replaced
(this makes sense with the symptoms)
now after some weeks of proper operation same failure (like
2.time) again. I hate to turn it in again only to have the symptoms
(the failed diodes) cured without knowing and eliminating the primary
cause of the problem ???
Anybody around who experienced the same (similar) problem and
who can tell me what caused it ???
hope to hear from someone
