JT-6188 Dual Band Radio External Speaker Jack Hack for APRS, Packet, Dopper, etc.

UPDATE: Coming soon- a "Receive Audio via the RJ45 Jack" mod (already tested & working). If you can use a drill and solder two wires, you can add an external speaker jack to this low-cost amateur 2m/440 transceiver. This mod is needed for operating Packet, most APRS, a Doppler Direction Finder, etc. NOTICE: As expected, this will likely void your warranty, proceed at your own risk. (Please pardon the video quality, it's my first attempt at YouTube.) -73, Gary N8RDF
