The AM Forum

Ran across this site today and have been enjoying some of the old publications.
Found a publication that goes way back called Radio Constructor. I am reading an
article now on building a AM/CW transmitter from the 1970 December issue.
Uses TT11 tubes, pretty cool.
I have ventured as far back as 1934 shortwave magazine.
    God i love this old stuff.

Good shtuff there OM!

A goldmine for sure. Found this. Who knew that there was James Brown Radio in Baltimore! The Derb knew what he was doing!

I was looking more at the old radio magazines from the 1920's thru 1979.
Next to the last selection box on the top labeled Early Radio,
when you run your mouse over it, it changes to magazines and features.
Then the first dropdown box is Hobbyist and Construction. The drop down
from that show all the magazines they have. They are mostly 100% in PDF.
Lots of cool construction articles on transmitters and receivers and even mods
for some of the older amateur stuff. Was kinda cool seeing Heathkit adds for
the new DX100 and advertisements trying to stoke up interest in the new
807 tubes..  ???

The old radio mags are compelling. I've spent WAY to much time looking at them.  :)

I think I have spent about 5 hours in the last 2 days going through this website. 

Between that website and this one  http://www.qsl.net/va3iul/ same here.
He also has a huge schematic list.

Mostly qrp stuff, but fun.

Check out the October, 1915 edition of Electrical Experimenter. 100 years ago they were figuring out telephone answering devices, how to make an antenna out of your upright piano's harp, Telsa's lawsuit against Marconi, a ook at German submarines and torpedoes, and science fiction predictions of an anti-gravitational devise for the war. I believe there was even a tetrode vacuum tube (Audion) circuit. What great reading 100 years later!
