display vibrates/wiggles on tx 14 MHz

 

Hi all,

today my display stated wiggling laterally on tx, but only on 14 MHz, and only when I keyed (I'm pretty much CW only). I tried lowering power but no change. Has anyone experienced this? Any thoughts?

Many thanks,

Since writing this, a few hours ago, it seems to have resolved but I don't know why. If anyone else has experienced this I'd love to hear.

Many thanks,

Tighten all your antenna connections and ground leads. Use rf chokes on head set leads, power cables ect. It sounds?like rf is getting into the radio display. This is a frequency sensitive issue.

Colin,
My gut reaction would be RF getting into the rig...? Check VSWR, substitute a dummy load for your antenna, and check all RF Jumpers and your ground connection...??
?
Have you added anything new to your setup; new Watt/SWR meter, jumpers, antenna, etc....
?

Snug all of the circuit board mounting screws.these are the ground paths for the unit. A problem often found in factory repair facilities.

Thanks David, Dallas, and Rick. I haven't added anything new to the setup, but I did check all my antenna connections and found one that wasn't snug, so maybe that was it. Thanks Rick for the suggestion of the mounting screws. Sadly a bit beyond my abilities but I'll keep it in mind. I'll keep a closer eye on connections and I'll get chokes for power cables.?

Thanks again, guys.
