Harvey Radio Labs 80-T

This is the manuals for my Harvey 80-T transmitter. Many thanks to Don N3RHT and Wayne  NTE for sending them to me. The big images are printable directly. Quality isnt the best because of age and simple typewriting. The first version of the modulator schematics made by Bengt SMHBV is below. It will be updated later, now published as-is. I have also made a page with pictures from the inside of my Harvey 80-T. Coil winding data is added below. Also have a look at Wayne NTEs Harvey 80-T in Kansas!

 Overall size of the printable pictures are between 150-200Kb.

The first 80-T manual made in Brookline, MA. in 1936 with extra schematics added.
