It is a completely self contained PDM modulated AM transmitter for 160, 80 and 40 meters. The transmitter is built into 2 medium sized 19" rack cabinets that originally housed polygraph lie detectors!
The VK1SV classy Class-E 160 m AM transmitter. Dimitris Tsifakis, VK1SV/SV1DET. Version 1. I will document here my adventures in the Class-E land.
A 200-Watt Push-Pull Class-E AM Transmitter for 1710 kHz. Max Carter. Input power (DC volts x DC amps): 220 watts. Output power (AM rating; into 50-ohm resistive load): about 205 watts. Peak envelope power (PEP; at 100% modulation): 820 watts. Operating frequency: 1.71 MHz.
Class E transmitters are high efficiency, reliable, solid-state transmitters. They are simpler to build than similar transmitters using vacuum tubes, and are significantly less expensive to both build and to operate.

In this page, I will describe how to make a class-E amplifier from scratch, that is how to design the circuitry required to produce a desired power at a desired frequency from a desired input voltage on a 50 ohm load (or antenna).
I’m building an 8-MOSFET class E AM transmitter capable of 400 watts carrier (over 1500 watts voice peaks). I will do a video for each stage of the building ...
