Title: 24 MOSFET class E 80 160 transmitter build looking for Elmer to help
Post by: KD6CXW on January 28, 2025, 06:41:01 AM
I plan on building a 24 MOSFET PWM 80/160 transmitter.
using a DDS VFO .
Looking for an Elmer to help with build as I am new to the Class E .
I've repaired and built tube amplifiers and worked on and modified tube transmitters .
I have found Steve  WA1QIX web site full off great information .
I've acquired some parts from a person whom decided not to build his transmitter, getting ready to order PWM boards and other parts .

Hi John:

I've only built a 6-FET PDM rig, but I am happy to attempt to answer questions as I can.

Okay, I did not look you up - where are you located?

There are three parts to the build
- parts
- the custom chassis work
- the labor

The 4th one, cost.

How did you decide that "24 Fet" is the right thing for you?

to many things going on, hard to find time for projects .
I have been reading Steve's site on AM PWM transmitters and decided  to go from tubes to solid state . Started collecting parts , will need more though . The fabrication is no problem that's what I do for work.
Finding time may take some work.
Need to order boards and parts from Steve then work on the DDS VFO , making sure it acts the way it should and with a touch screen display with options I would like to add.
