Hi mmcp42 and welcome,
Firstly, if you fly in an area covered by OGN-R then you will find that you get better notification of gliders and other FLARM traffic through that system. Not to mention fewer antenna, fewer cables and not need an additional 9v+ power supply.
If you want FLARM for other reasons then I would look at the FLARM Eagle, the cleapest version will be satisfactory.

Plug the USB into a spare port, noting which one, then go into the PAW config and set that same port to FLARM and the same baud rate as your Eagle(4800?).
Although I have not mentioned which wire in the cable goes where, or how the ports are numbered, that is it. Job done. Cover that when you need it :-)
If you do fit a FLARM unit, you will still get notifcation of FLARM traffic through OGN-R, so covered both ways.
