    The purpose of a Forum is to share information. How about posting information here instead of doing it offline? Thanks! :)

    Here is a link to SPA-1/APA-6 manual pages in html format:

    AN 16-30: This does not make sense. "AN" stands for Army/Navy and is prefix to indicate the designation system. 16-30 is not a correct designation format.

    NAVSHIPS 900,768. : This is an incomplete document number, in wrong format. The comma should be a 'dash".

    Thanks, Mike! I greatly appreciate your assistance. Robert did not have the specific documents.
    Best regards.

    FWIW -
    Early Navy Bureau of Ships (BuShips) manuals did indeed have numbers with commas like NAVSHIPS 900,768 - I have dozens of them in my library.

    And yes, the AN 16-30APA6-7 format is typical for US Navy Bureau of Aeronautics (BuAer) manuals.
    Here is an example page from the AN/ANQ-2 manual AN 08-ANQ2-2

    And yes it is confusing that the AN in AN/APA-6 stands for Army-Navy rather than Aeronautics.
    Not to mention something like AN-222/AN which would be an ANtenna for Airborne Navigation use......

    Nick, still looking for an AN/BBW-1 (which would be an underwater remote-controlled pigeon)

    I knew I'd screw up - AN-222/AN would be an Antenna for Airborne Recording use.
    AN-222/ANN-222 would be an Antenna for an Airborne Navigation Recorder.....

    That's what a get for relying on a vintage brain - AT-222 is an antenna, not AN-222
    I quit.

    I replaced the manual excerpts on my link with a complete manual ( ). It's a preliminary version so does not have a Tech order or AN number assigned to it. The manuals I have listed with the AN/APA-6 are AN 08-10-218 and AN 08-10-219. I suspect, but cannot prove, that the difference is that the -218 covers the APA-6 set that includes a modified Hewlett Packard 200-C oscillator (nomenclatured O-10/APA-6X) for Lissajous measurement of radar PRF, while the -219 does not include the oscillator.
