Instruction Book for Model 150-B Radio Transmitting Equipment
Consisting of Type 02520 Radio Transmitter and Type 02433 Exciter Unit

Output: 150 Watts Radiotelegraph
Output: 150 Watts Radiotelephone

Manufactured for Signal Corps U.S. Army
By Meissner Manufacturing Co.
Mt. Carmel, Illinois

Order No. 13759-PHILA-43 Dated: October 18, 1942

77 pages, 8 1/2 x 11 inches, one fold out schematic (in two pages).

As many know, the Meissner 150-B is one of the more remarkable rigs manufactured in the golden age of ham radio.  It seems everything made by Meissner was built to be dropped off the top of the Empire State Building and still work, and the 150-B, designed for the Signal Corps, looks as if it could have done double duty as a pile driver.  You won't have to own a 150-B (I only own the exciter unit, a military version of the Signal Shifter) to find the manual interesting and enjoyable to read, provided you appreciate vintage AM and CW gear and the style of writing of the day.

At ~350 pounds, the transmitter unit is a boatanchor with a capital B (maybe that's the meaning of the B in the model number  Cheesy) but a restored and operating 150-B is a rare thing of beauty to behold (four 866As!).

The exciter schematic is also on the main schematic page and the manual covers the exciter, so this manual is probably of use to Signal Shifter owners also.

Additional Meissner 150-B information and photos of the rig in all its gray wrinkle glory can be found here:


Wayne Steiner N0TE authored an article on restoration of the 150-B which was published in the September 1996 issue of ER no. 89 on p. 24.

There are four PDF files listed in the following order:
1. A larger higher resolution (and larger file) copy -- 28 Mb
2. A lower resolution smaller file for readers -- 13 Mb
3. The original schematic (the manuals have a higher contrast schematic with the creases reduced) -- 939 Kb
4. The original schematic on one 11 x 17 inch page -- 4.7 Mb.
