Testing MRFE6VP61K25H

Big HF load
It’s based on a copper plate, big old whipped aluminium radiator and two 100Ohm resistors, 800watt each.
Check losses in big LPF
Not good at all — heater 🙂
Just photo of mrfx1k80h amp. parts

Small things.
Water pump for mrfx1k80: RD16 kit: Optical encoder for wolf: Had an issue with it. Seller mentions that it works with 5-24v
Photos of soldering water blocks to the copper plate
2 U-channel blocks: Soldering paste: With bottom preheater 🙂 We need to cook: Nasty flux and solder stains: A bit polishing: More:
Finally — finished big LPF
1.2KW LPF
High pass filter for the LPF for MRFX1K80
My LPF board contains hight pass filter to split harmonics to the 50Ohm load, instead of returning it to the transistor. Measurements.
Received coils and relays. (LPF)
But no wire 🙁 Looks cool.
Paper QSL from Japan and some work.
Paper QSL and work on the 1.2KW LPF and amplifier controller.
