These are the same as the ones I picked up at Fry's locally. Better price on the Internet, but I wanted one quicker. I pulled the stereo connectors off of one of them and that pretty much destroyed the solder pads and nearby lands. Fortunately, the needed pins all go to the "solder" side by vias which makes it easy to connect without pulling the connectors off.
The "power" LED does indeed function as the activity LED so no need to add one for that. The necessary SW 3 & 4 connections for COS and CTCSS are also easy connections. My plan is to use a 2N7000 for the PTT line as mine connect to a 2 port controller's COS input.
I've not yet investigated whether the other LED can be reconfigured for the TX indicator.
