Hello group,

My transmit converter is now finished and tested - it survived two
sessions of 50% duty cycle WSPR transmissions on 475 kHz and the
results are great. I thought others may find this useful, so I have
put a write-up on my web page:

http://people.physics.anu.edu.au/~dxt103/472/nltt/ 

It is a 50 W class-e PA designed for 50 ohm impedance, so there is no
need for an impedance transformer. Doesn't get simpler than that :-)
The driving circuit is based on G3XBM Roger's design with the
difference of a 10 MHz OCXO LO and the addition of a beefy MOSFET
driver.
