[Hallicrafters] Re SX-117 Mods In HT-44 Manual - WA2CWA The ManualMan Says

[Duane Fischer, W8DBF]

Re Skip asks: Why do the modifications for the SX-117 receiver appear in the 
HT-44 transmitter manual instead of the SX-117 receiver manual?

Some claim that Hallicrafters never copyrighted their manuals, but those in 
the know say No, not so.

Where does one find the copyright date?


>From Peter Markavage, WA2CWA who has provided many of us with original and 
reproduction manuals for many years.


If you words to the effect like "copyright 1963" or something to that
effect, most of the Hallicrafters did not have those words. However some
manuals did imbed a date in the part number for the manual. Also, for the
HT-44 manual, the back page, lower right, it gives the part number for
the manual and below that, the numbers 1163. The number, 1163, I'm told,
stands for November 1963.

Since the HT-44 and SX-117 could be interconnected to do transceiver or
"slave" type functions, Sections 7.1 and 7.2 of the HT-44 manual, does
provide certain modifications to the SX-117 to improve its performance
when used with the HT-44. This is not to be confused with the errata
sheet and updated schematic that also came with most of the HT-44
manuals. This info was added after the manual was printed. I guess it was
easier to add the errata sheet and schematic rather than editing and
reprinting all the existing manuals. Note, it was not uncommon for
manufacturers of that time to include modifications to other pieces of
equipment in their manuals, especially if that equipment was targeted as
an adjunct or integral accessory to the equipment that the manual was
written for. Johnson did this and so did Central Electronics with several
manuals written for their equipment.
