[Kenwood] TS-430S Question

[Dave Holford]

This is a known problem and happened to me years ago.
It is apparently caused by 'dry switching' - no current on the contacts when 
switching.
There is a simple solution which I believe was recommended by Kenwood and 
puts a small current in the circuit. I performed the mod on mine and it 
resolved it permanently.
I can't remember the details, and I sold the rig some time ago but I'm 
pretty sure you can find it in several places, inlcuding mods.dk

Good luck
