HF/6m linear amplifier 600W for digital mode palet with MRF300AN and MRF300BN 80% efficiency

You are using 2-30 Mhz wattmeter element to measure power on 50 Mhz leading to inaccuracy in the measurement. The power on this band is probably greater than 400 W.

This pair of MRF330 is really fantastic and works very well in your project.73. PY1LO
