Anyone have any suggestions for higher power in a Hamtronics 6m
Repeater (REP200)
I have the 25 Watt PA, and initial testing is showing the receive
sensitivity far out distances the ability to transmit.
I am able to get into the repeater from 50 miles, but have to be
within 25 miles to hear it.
I would like to have the potential for 100 to 150 Watts, if this
will bring it back in line.
It is currently being tested at 90 feet with 1/4 wave homebrew
antenna. It has been tested at 50 feet with the same combo in
another location, and the results have been the same. Both
locations were temporary to get an idea of performance after
isolating a duplexer problem and correcting the resulting desense
problem.
It is also possible that the final resting spot (197 feet elevation
with Comet antenna fed by 25 feet of 1/2" hardline) will improve the
balance between TX and RX. This will be 100 feet higher than the
current testing location, and far better feedline in terms of
quality and length.
However, if the combination of higher antenna height and shorter,
less lossy feedline do not bring it back in line - What would be a
good choice in external PA to do the job?
I know this is an open-ended question, and probably far short on
info to provide a definite answer. I am only looking for possible
options here.
Thanks,
