We have recently had a couple of instances of severe interference on our
repeater.
1)An energy saving lightbulb- acting as a -600khz transposer 200ft from our
repeater.
2)A Dell computer monitor- again as a transposer, but very strong.
Both instances took some weeks to DF and rectify.
This repeater is internet linked and during the trouble we used a remote
reciever via Echolink. Once the users had overcome the surprise of hearing
their own voices at the end of an over, Echolink became a useful alternative
to switching the repeater off.
The remote Rx had the spare logic unit connected to it to provide ctcss and
toneburst gating before onward transmission via VOX to echolink.
DTMF functionality was a lost.
I can see many other possibilities commercial and ham of remoting a
receiver during periods of deliberate/accidental interference.
