[Milsurplus] TBY test data report

[Dave Merrill]

I found I have a TBY-8 manual with test data for s/n 1399 made by Colonial
in Buffalo, NY, dated February 1944.  There are 14 pages of actual test
results and 22 pages of pre-printed Typical Test Results. The receiver and
transmitter tests were signed off by different individuals as were the
backlash, power output and sensitivity tests. I imagine they had multiple
dedicated test benches with technicians trained for each test so they could
queue 'em up and run 'em through.

Most signatures are just a last name but Nina Buscaglia signed her full
name once. Found her in the 1940 census living with her parents and
siblings in Buffalo. She was 17 in April, 1940 (census day) so she was not
yet 21 in February when she signed off on s/n 1399. Just one of many women
and men recruited for wartime production work.
