A project to build a cross band repeater using a pair of Baofeng UV5R handheld transceivers.

Nice feature of the Baofeng UV5R family is that they support 6.25kHz tuning steps. That fact makes it possible to dial in the radio to use the exact PMR446 channel frequencies rather than a nearest fit which is the case in many other transceivers.

Baofeng UV-5R uses RS232 to communicate or programming with the PC software and you can make your own programming cable with a few components.

A tiny board, which allows a smartphone or similiar device to connect to the Baofeng UV5R radio via a TRRS audio connector. It allows for connecting the radio to a software TNC app such as APRSDroid or PocketPacket. Solder on the components, solder on the cables, then provide some stress relief, (I use solid-core wire and heat shrink tubing), and you can use your UV5R with your smartphone for APRS on the cheap.

Fix the no-mic problem with the Baofeng UV5R+. It may happen the carrier wave is there, but there is no modulation.
