WOW. That is quite a document, big THANKS for finding and reporting it !
I have an 'Acceptance Test' manual, for later model of TBY, but this report is much larger. And more interesting.
I recall around 1980 i was offered a TBY for $75. It was in a metal case, not that much larger than the radio, complete, but -
missing the bag. I guess the owner threw out the bag because it maybe was moldy or smelled bad. I passed up on this deal.
In retrospect, i should have gone for it.
BTW, the few bags for the movie 'Windtalkers' were somewhat wrong on the dimensions. I think it was the antenna sections
storage that was too small. Nevertheless the bags sold for $250 each. Bags nowadays are X-rare. I imagine in future years the
provenance of these later manufacture bags will be of course be lost, and some ingenious imaginations of why defective TBY
bags exist, will be bandied about.
I have a wooden TBY transit case, but i don't yet know what model it carried.
I do not think the latest model, -8, was ever used in combat. The 8's all seem to be new condition or hammified.
I used the TBY with AC supply in the mid 1980s to jam an apartment neighbor's loud TV. With a nearby TV tuned to the same
station as he, for visual feedback, and careful tuning of the TBY, you could selectively adjust the TV picture's horizontal hold.
Most annoying. I mentioned this previously and some other reader responded that he found the same use for the TBY. TBY veterans.
Maybe 2 - 3 years ago some "National Electronics Museum", i know nothing about this organization, had a deaccesssioning sale,
cutting down their stock. I don't know at all the ground rules or what their goal was. One thing offered was the Westinghouse
HR ( "Handy Radio" ) TBY forerunnner. I have the radio magazine paragraph announcing this new radio, i think 1940. It was single
band, not the higher VHF extension. The museum offered one with Spanish language panel markings. I wrote them and offered to
buy it, or for some means whereby i could bid, no answer. So be it. I think the radio was to be offered to railroads and maybe
similar utility uses.
OH yeah. And Fair Radio, back in the 1970s or 80s, had the 75 MHz ship antenna for the TBY. This was used so convoy ships would
not have to use LF or HF radio inter-convoy, which comms could have been tracked by U-Boats. This is fact, not imagination, and
i talked to a fellow who had used the TBY for exactly that use. I forget his name; he owned an AM BC station in Nebraska, i believe.
So thus endeth this chapter on the lore of the TBY.
