Wireless Telegraphy and Telephony 1922

Here's the 1922 edition of A. P. Morgan's book; earlier editions were published in 1912 and 1915. Just for fun we see a couple of pictures of field radio equipment; unfortunately, the pictures themselves aren't dated. From Steve Davis.

Telefunken wireless cart, transmitter side:

And the receiver side (you couldn't exactly call this a transceiver):

As always, click on the images to bring forth magically the larger versions.
