[1000mp] What is Wrong with SWR Meter?

Tue, 4 Jun 2002 23:06:23 -0000

Morris,
I have tried different configuration the whole afternoon with the same
results. One of my friends suggested, that there is something wrong in SWR
reading module and it reduce power (transceiver see, that SWR is too high
and reduce the output to not let damage amplifier of MP). It happens even
with perfect antenna.

only to MP. My MP shows some swr on 21Mhz even on DL but I just disregarded.
Also try with tuner out of circuit see if this helps. If you have a DL you
should have already tried that.
