This repeater is in the middle of nowhere. The nearest
house is at least 1/2 mile away. No link radios are
involved. The repeater itself, when connected to the
antenna, is the only thing putting out energy on 444.5
MHz. We see a rise in noise level on the receiver port
of the duplexer when the transmitter is on, and this
is not present when the repeater is feeding a dummy
load.
Thanks for the thought, however.
