[Elecraft] Local Beacon Splatter

[Jack Brindle]

I would ask this another way. What has changed recently. It certainly sounds like the transmitter is at fault, but similar situations can arise in conditions local to your station. Have you changed your antennas? Has something changed in your antennas? Something in the feedline or antenna with diode action could cause a similar issue. This could be a discontinuity in a connection (rust, corrosion) or something similar that is causing mixing of two or more signals. Just disconnecting your antennas and listening with a short whip may not be good enough to find this since you are still interacting with the local issue.

You should take a 6m receiver out and listen to the band away from your station, so that you hear the transmitter without interaction of your antenna system. If you still hear the beacon problems, then the owner certainly needs to know they have an issue.

This can be a rough issue to resolve, both on your end and the transmitter side. So many factors may be involved that the issue gets very complex (such as a diode action on his side, caused by an issue in a local commercial transmitter). Good luck resolving it, but be aware that there will be a resolution.
