Inexpensive Cross Band Repeater using 2 HT's

We had a successful run with the $30 RPT-2D repeater cable using two Baofeng HT's. One radio was set to talk on 446.000, the other was set to talk to our local repeater on 146.805. The cable links the mic/spk ports of the two radios. Had 6' of separation between the radio's to prevent the 2m side from locking in TX. Worked perfectly!

We took the Neo-6M GPS module from a previous tutorial, added the LCD Rotary Encoder shield, and are displaying the GPS data (lon / lat, time / date, altitude, speed / heading) on the LCD. Turn the Rotary Encoder to display other "pages" of information. (For Internet Time Client, see http://www.instructables.com/id/Arduino-Internet-Time-Client/)

GPS Rx to Arduino pin 12
GPS TX to Arduino pin 11
GPS VCC to +5v
GPS Gnd to Gnd
