Just fitted latching ae relay in my 9Cm.
PTT goes to small 12v DPDT relay, center to pos, then normally closed contact to rx side of ae relay, and the normally open to tx side. Seems to work ok, 2 components, relay and diode of course, no semiconductors, bish bash bosh.

I know G4HUP used to do one but they are no longer available. The W6PQL one does work really well and I have used in past but at $20.00 + possible duty it can mount up.
Are there any other boards out there that work as well?
Thanks
