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  :D) 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.
