By Larry Clore, WB9F

Concept:
Modify the Low Power Setting in the Midland 13-509, Cobra 200, or Clegg 76 for link duty.

Modification information:
Here is a modification for the Midland 13-509 to increase low power from 1 watt to 5 watts output. This mod is from KB9JNO. By increasing low power to 5 watts, we are able to use the 13-509's for link radios for our 2 meter repeater.
