I came across a Hallicrafters 11 page "Suplimentary Data for
Attenuator and Impedance - Matching Networks" brochure. It's
from 1957 and was published to help design matching between
exciters (HT-30, HT-32, etc) and linears. It has simplified tables
for DB to voltage/current ratio and power ratio tables and a table
of "T" attenuator values for a given DB attenuation ...as well as the
associated formulas. I made a few copies, if anyone wants one
it's $3 postpaid. You can carry this in your pocket. I'm OK in
any callbook and QRZ.
