Hi again guys .After tuning a notch mobile duplexer with a service monitor
and spectrum analyzer .The tuning indicated the duplexer was tuned
correctly but when the 40 watt transmitter was applied then the output of
the duplexer was around 10 watt then certainly something is wrong with the
duplexer.I wonder if the low output of the duplexer is not bad matching of
cable length but is more tied up with a faulty duplexer.maybe a burnt track
of carbon inside the tuning tubes? Any thoughts .I have tuned 6ld450s notch
duplexers with no worries and they produce 20 watt or more from 40 watt in.
Thank You,
