Tom,
You mentioned in an earlier posting that you had a six-cavity duplexer.
Most six-cavity duplexers will have an insertion loss of about 2.25 dB,
which means that with 70 watts in, you should see about 42 watts out. If
you actually were measuring 45 watts out with 55 watts in, your duplexer ha
That's typical. Duplex is a different animal. If there's a slight problem

Yes, the advice is all good and I have tried several of the suggestions and

One thing to keep in mind about a particular PA's tendency to "go spurious"
is that it will probably be well-behaved when tested on the bench while

Your 6-meter J-Pole will be about 18' long for the active portion, plus some
length for mounting. It will probably end up being the same length as the
Diamond.
The gain will be 2.6 dBi. A J-Pole is effectively a vertically-oriented
