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 Paul Young, K1XM 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. To TS-930 C ------------o / 6800 B |/ o--------/\/\/---| To Keyer |\ _\|_____ E | | ----- --- - 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. --------
