This software is beeing used to drive the K08_mchf_PA. This PA is not only for the mchf but also for other QRP-transceivers when used stationary and is able to produce app. 100W from 2 W drive and a maximum of about 150Watts. It includes a low pass filter and a automatic antenna tuner. All this is handled by a arduino mega processor. Schematics will follow soon.
