Let's wrap this with a bow. I have tested this interference on 7 radios. 6 of them here and all 7 hear the interference. Simply stated the interfering station is over 100 miles away and is breaking squelch 10 Khz away on a Bendix-King 5102X with a rubber ducky. Yep. 100 miles away on a rubber ducky 10 Khz off frequency. Someone is wide, loud, and powerful. The receiver is a Yaesu VX4100 with 85dB adjacent channel selectivity at 20 Khz. That should be about 80 @ 15. If I have to switch to like GM300's what guarantee do I have that the problem will be any better if the other party is running excessive power and wide deviation?
I have a complaint in with the coordinator and have not received any acknowledgement that the issue has been received. I also emailed the trustee and have not received a reply. I like to keep this cool and cooperative. Back to the question, though. Will something like a Angle Linear get in close enough to knock down interference that close? --- In [email protected], "Paul Plack" <pl...@...> wrote: > > Back in the day, a channel was 30 kHz wide.
