[Kenwood] TS-430S Keying Problem

[Joe]

Hi Ken and others.

Same Power supply,

One would think that after a rest if anything thats when the supply 
would have ummm well some short bursts stored in the caps ya know?

But yeah how accurate the amp meter is on the rig is anyone's actual guess.

But under full power it is guesstimating around 17 to 18 amps on the 
meter.  I backed it down to where it is at 15 amps on that meter and 
tried to make it do the same errors. and with the short tests I just did 
it never did it.  so  that may be the cure,  just keep the current draw 
down some.

Awesome Thanks on the simple hopefully permanent fix.

Now does anyone have a way to make the vox delay hang time more 
variable.? at least longer for like when rag chewing?
