Maximize your QRP setup: Step-by-step guide to convert ATU100 into ATU10

I show you how I converted an ATU 100 100 watt rated Antenna Tuner into a QRP enabled ATU10 with a transformer winding change and re-programming the PIC chip using a PICKIT3 programmer. This allows you to make full use of the ATU 100 for QRP transceivers.
