Can anyone supply me with a reference for modification of the WB4VVF Accu to positive polarity for use with my TS 430S? TNX 73 Cliff (KF8K)

This is an article from the August 1983 Scuttlebutt (the Yankee Clipper
Contest Club newsletter). I've used this circuit with a TS-430, and it
seems to work. Anyways, it's real easy to try.

A TS-930 Quickie

I guess my TS-930 works differently from John's.
It has some minor quirks, but I like it. One
problem which he had also plagued me - the
inability to connect an Accukeyer to it. Rather
than open my Accukeyer and add another output jack,
I built a simple level converter. It's very non-
critical, and only uses two parts. The transistor
can be any NPN device. I used a 2N2222 because I
had one in my junk box. The resistor is similarly
non-critical, and can probably be +/- 50%, whatever
is in your junkbox.

This circuit takes advantage of the unusual config-
uration of the output stage of the Accukeyer. I
don't know if it will work on any other keyer.
