1954-59 USAF Navy AN/GRM-4 Boonton Signal Generator Technical Manual Set 3 Manuals

Original U.S. Air Force / U.S. Navy technical manual group for the Signal Generator AN/GRM-4, manufactured by Boonton Radio Corporation.

This binder is especially desirable because it appears to contain multiple related manuals covering operation, overhaul, and illustrated parts, rather than just a single handbook.

The photos show:

• T.O. 33A1-8-3-1 — Handbook, Operation Instructions, Signal Generator AN/GRM-4
  Dated March 1, 1954
• USAF T.O. 33A1-8-3-3 / Navy AN 16-30GRM4-3 — Handbook, Overhaul Instructions
  Dated April 15, 1954, revised April 30, 1959
• T.O. 16-30GRM4-4 — Illustrated Parts Breakdown, Signal Generator AN/GRM-4
  Dated April 15, 1954

The manuals state that they were published under authority of the Secretary of the Air Force and Chief of the Bureau of Aeronautics, giving the set both USAF and Navy relevance.

The AN/GRM-4 was a military RF signal generator produced by Boonton Radio, making this a useful reference for collectors and restorers of Cold War military electronics, radar/radio test equipment, Boonton equipment, USAF technical orders, and Naval aviation electronics.
