antenna patch
I have tried the LiPo battery and I have also used an external power supply set to max 4.45 volts DC @ a max AMP of 2.25
VBATT to GND reads 4.33 VDC
Please see attached pictures and included sketch with the I.M.E.I section removed due to restrictions of forums.
It is my hope you can help me see the error in my ways and find a solution caused by an ID10t error and not a hardware issue.
Many thanking Ewes'

/***************************************************
This is an example for our Adafruit FONA Cellular Module
since the FONA 3G does not do auto-baud very well, this demo
fixes the baud rate to 4800 from the default 115200
Designed specifically to work with the Adafruit FONA 3G

----> http://www.adafruit.com/products/2687
These cellular modules use TTL Serial to communicate, 2 pins are
required to interface
