I'm building a Mitsubishi RA amps for vhf and UHF ... and a dual mosfet for HF ..?
All controlled by a Arduino nano ... well actually 2 arduino Nanos... one for v/uhf and the other for the hf with lowpass filter ...?
80w on v/uhf and ~100w on hf ... the hf amp was part kit on ebay ... I can't remember the part number off hand ( I'm at work -- nites ) MiniPA100w come to mind . -- and if you know it, yes , one of the kits arrived with a fake dual mosfet.?
You can find my --- kinda progress -- on YouTube.?
