I use TX-INHIBIT on my K3 and have a webpage showing how: http://www.kl7uw.com/TX-INHIBIT.htm
The circuit does include the FT-847 so is more complicated than you need. Instead of the voltage regulator you apply 5v thru a 2.2 to 10K resistor directly to pin-7 on the K3 ACC jack. The Station Master must ground pin-7 to enable transmitting. Where you obtain 5v is an issue and it seems it should be available on one of the ACC pins. I'm not doing that.

I read page 19 of K3 Manual that says: "An external 2.2 to 10 K pull-up resistor (to 5VDC) is required". Well that is NOT very clear to me.....(perhaps I am to old...Hi), could some more clever explain better how to do it or a small schematic will be appreciated as example where is the 5VDC ??? I thank you in advance for help and assistance on interpretation.. 73 and DX i5NPH 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-100w, 1296-testing*, 3400-?
