Re: Microwavers Audio Keyer

Interfacing to PTT lines, with the 'industry standard' diode, really ought to be done pulling down the base of a P-channel device, with  potting down so the actual threshold occurs at several volts above ground.

I have seen several commercial products that simple take PTT via a R to the base of a transistor, so the threshold is around 1V, as Ian says.   Poor design and attention to detail on the manufacturer's part

Hi Ben,

My first criterion in choosing a rig is that the tone must stay the same.
This is done by offsetting the dial frequency by the CW tone when changing
from SSB to CW. Yaesu and Elecraft rigs do this, but I don't know about
recent rigs from other manufacturers. I bought an Icom many years ago
without realising that it could not do that - I didn't keep it long.

Is there a potential problem here. 

Station with audio CW, ie tone on SSB tries to contact station with 'real' CW, ie me, so I push one button, SSB to CW mode, and key up but now my tone on the other chaps rx alters, he retunes. But when he tx's to me his tone will be off so I retune,  etc etc.

Or am I missing something (again)?

Let's hope we all know where our IRT buttons are.
