Wow! It even has its own built-in VFO. This PW rig is a great
design for guys wanting a simple solid state version or even
a hi-fi AM driver for a low level linear system.

You da man, Bill!

Use an "AM Courtesy Filter" to limit transmit audio bandwidth  +-4.5 KHz, +-6.0 KHz or +-8.0 KHz when needed.  Easily done in DSP.

Bill,
Consider a small resistor in the source lead of the modulator FET. This will make it more linear and stable over temperature.

Sadly, the author is a SK.  If someone has saved this schematic locally, please post it.
