Fellow Kilocycle Chasers:

(1) Radial, in this instance, is a line drawn on a map. An engineer draws
an azimuth (a line) on a map, and drives to points on each azimuth and
measures the field intensity of the station in question.

And field intensity is measured in microvolts, millivolts, or volts per
meter. E.g. 1.00 mV/m. That means, for that much signal strength, 1 mil-
livolt would be induced in a vertical antenna of one meter height.

The way that Craig refers to "radial" in this instance may be confusing:
it's not a wire.

Uncle Chuck will now tell a story, kiddies:

[In May 1962]

Hammett & Edison Consulting Engineers (San Francrazyville) sent me a copy
of a complete engineering report sent to the FCC as part of an appli-
cation for a CP by Radio One Five Hundred, Inc., owner of WNDI-1500 (now
WBRI), Indianapolis. The whole 50 pages, complete with field intensity
measurements of their little 58-watt field intensity transmitter, KSJ835.
I had heard the open carrier of KSJ835-1500 w/IDs on the hour, queried
the FCC. FCC sent me the address of H & E, I sent a report of reception
to H & E, and H & E sent me a QSL plus engineering exhibit (report)!

Radio 1-500 couldn't get a CP immediately because of interference ratios
with WSVL-1520 (now WKWH) Shelbyville, Indiana. The engineering exhibit
showed that the prohibited overlap would occur in a rural area, and would
be a small area. FCC granted the CP.

And I, a young, snot-nosed BCB DXer of 15, had this WONDERFUL exhibit to
drool over. WOW, this is INTERESTING!

The QSL was signed by Mr. Roger (?) Edison of that firm for a report
for KSJ835.

THE STINGER:

In (about) 1992, VOA paid for a bunch of prospective Foreign Service
technician employees (me included) to attend the NAB Engineering Con-
ference in Washington DC, that year.

During the banquet, I was seated next to a gent who had on a name tag.
Happened to glance at the tag....It was Roger (?) Edison of Hammett &
Edison Consulting Engineers!!

Astonished? More than that. I introduced myself to the gent, and told
him of my report back in 4/5/62 on KSJ835-1500. He remembered the
report!

Sorry, folks. I thought I was going into commercial broadcasting when
I grew up. The Navy intervened in 1966. Then I got a family and after
getting out of the Navy I figured that I'd never make enough as a
radio technician ("engineer") to support a family.

I still got my wish though, except I ended up in gum'mint broadcasting,
VOA.

If the taxpayers ever knew what I did with their money in the Navy &
at VOA, I'd either (1) get a medal, (1) get executed, or (3) both.
