Interesting thread...............and lighten up IS in order these days.
And, it was Angelo Diddy...........not Dundee! (Angelo Dundee was
Muhammad Ali's trainer)
I built and engineered an AM station in the metro Atlanta area and
Angelo was indeed a stickler for details but also a nice gentleman.
Took his job seriously, but professionally. Talk about need for
accuracy. FCC rules had to be followed explicitly. Frequency
deviation allowed was +/- 20 cycles. Power levels were required to be
maintained at no more than 5% over or 10% under the licensed for level.
Oh, and the Proof of Performance measurements and the skeleton RF
proofs that had to be made on a regular basis. It wasn't uncommon for
the FCC to "drop in" from time to time. It was Angelo who did the
first inspection when we went on the air. And the FCC monitoring
station at that time was in Powder Springs, GA., another metro Atlanta
suburb. When I think of accuracy, all these and more come to mind.
Thanks for remembering Angelo.

I understand EXACTLY *what* Larry was saying.
My issue was with:
1: Receivers do NOT need to be that accurate - transmitters do. (Yes
-
I know us old goats with boatanchors and split Rcvr/Tx MUST be more
careful! I started within months of getting my license going down THAT
path with an HT-37 and an SX-101A.)
2: The LAST comment of the post:
> Wonder what box of cereal he got his license out of.
This, to me, hits a broad brush approach, and slaps Hams in general!
*IF* that piece HAD been left off - NO beef at all!
This Mail List is INTERNATIONAL. We, the base members of the list,
MUST
be careful with what we own and how we put it forward!
I've been a member for five to seven years. If we aren't careful, we
can trigger a lashback that *WILL* bite back.

I believe *EXACTLY OPPOSITE*, based on:
>> Wonder what box of cereal he got his license out of.
THAT implies the opposite of what you are saying.
> Makes BIG difference in price if has to be worked on or has been
dinkered with.

If it is either an R-388, R-390, or R-390A, and you base your value on
the PTO accuracy, then I'd say you have personal issues. It should
*NOT* affect value!

I agree with Hollingsworth! We used to have Angelo Dundee come visit
and have coffee with us in FOUR Land. Very nice gentleman!
Anyone not remembering Angelo, do not despair! He was the Enforcement
arm of the FCC based out of the Atlanta Office.
My first reply mistakenly used a transmitter for reference. My *very*
bad error! I was trying to make the point that ALL of us can suffer
the
issue of *NOT* knowing how far out of calibration a VFO/PTO may be!
This can be additive factors making it happen. Calibrator NOT in sync
with WWV or other equivalent standard, Dial zero point off the zero
because we changed band segment, and/or system crystal gently goes
drifting off and *WE* didn't catch it. Lord only knows - R-388s,
R-390s, and R-390As have enough of them, and their associated trimmers.
End of transmission
