[Collins] 75A-4 info

[telegrapher at att.net]

I picked up an original 75A-4 manual at a recent hamfest and it had the following insert.

75A-4 Modification for BUSHIPS.  520-5468-00, 1 June 1956.

Takes the 15 meter band and makes it cover 4.2 - 5.2 mc, the 11 meter band and makes it cover 13.0 - 14.0 Mc and the low 10 meter band covers 5.2 - 6.2 Mc.  I don't recall seeing anything about this previously.  Is this something unknown or something that may have been covered several years back before i associated with this list?  I've never heard that this was done for the navy.  It's all typewritten like it might have been done at the factory cause it's certainly not in the style of some ham or off the wll mod.
