[R-390] [KA9EGW] s/n 4214 preliminary test results

[ka9egw at britewerkz.com]

The Measurements 82's setup is pretty self-intuitive.

Test setup: a couple-feet hunk of 18AWG stranded jammed into the center pin
of the sig/gen's "N" connector and the 390's "C" connector.

Output set to 400cps 30% modulation and verified with o'scope of known
calibration.

Minimum detectable signal at 7001 kc: <.1uV.  At 500kc: .3uV.  At 3500kc:
.15uV.  At 10000kc: WWV overloads the 390 on said 'antenna'.  Actually,
pretty much everywhere the set tunes, on every band, there's something to
hear on such a little wire inside a building...so these readings are not
conclusive.  A closed, shielded system would be conclusive.  The point is,
after almost 60 years, the beast still "does the deal".

Oops, I didn't even peak the antenna trimmer before snagging these
measurements.

Reckon if I want conclusive data I'll need an N-to-BNC adapter [readily
available] and a C-to-BNC [*frightfully* spendy].  Or SO-239 to N/C.

Suggestions?  I'm halfway tempted to rip the "C" for an SO239 but I'm
guessing it's hooded and all that and besides Rule #1  around here is "Thou
shalt not butcher"...implementing MOW's is OK, but butchery by any other
name is still "ne kulturny".

TIA.  73, Brian [grinning]
