Where was all that talk about "phase noise" over a decade ago?
Hint: Cellular telephony had not the impact on electronics design
a decade and a half ago. "Phase noise" wasn't talked about much
back then. Some MUST have their buzzwords to sound "grown-up"
in hum raddio... :-)
Hint: It must appear that way to a fellow who spent his time reading
only about cellular telephony. The term "phase noise" was commonly
discussed "back then" as regards synthesized HF transceivers. Many of
we grownups where discussing it two decades back.
There were contests a decade ago and farther back. Those that
don't have much to communicate can always have "contests" to
prove they are "somebody" through point scores. :-)
That you see no value in competitive endeavers doesn't really effect
those of us who do. How are you effected by amateur radio contests?
Especially good point scores through the efforts of "reducing
phase noise." :-)
I guess it is the little smiley which really makes you sound like a
person uninformed on the issue. How is it possible for you to have been
a PROFESSIONAL in radio, a PROFESSIONAL in the design of synthesizer
circuits and to have been unaware of the problem of phase noise with
such circuits?
All that's needed is for
him to obtain a valid amateur radio license, and an amateur radio station.
Why are you so focussed on all MUST have a ham license to
discuss anything in here?
You've discussed. You just have no experience in amateur radio, no
stake in amateur radio and no credibility in amateur radio. You needn't
have an amateur radio license at all. Does that clear things up for you?
More tsk. My choice of residence location is NOT primarily
motivated by any slavering desire to erect a radio station of
any kind.
Great. It looks like you've got your wish. My Cincinnati home was
somewhat motivated by a desire for a good radio location. My present
home was selected in large part by a desire for a great radio location
with few neighbors. In addition, I have dark skies, a view to die for
and quiet which city and suburban dwellers don't even notice they don't
have.
Residences are HOMES, a place of living.
Residences mean many things to many owners. My living here includes
amateur radio, guitars, computers, astronomy, reading, writing,
photography, videography. I have neighbors who do none of those things.
Their residences are for what they enjoy doing in their manner of
living.
I've lived ON a huge radio station long ago, one much bigger than
is possible in any residential area. Not my idea of living for the
rest of my life...but important back then. If you want to live ON
or IN a radio station, feel free to apply for a broadcasting license
and make sure the local ordinances allow living on business
premises.
I currently live in the midst of a goodly sized radio station. I didn't
need to apply for a broadcasting license. I have no business on the
site and it wouldn't matter anyway. This county has very few
restrictions or zoning laws.
For a small part of my life the radio station complex was built
ON an old airfield. Not even the old Press Wireless station
in Palos Verdes, CA, (the one bought by a ham) was that large.
....but one man, Don Wallace W6AM bought that 25 acre Press Wireless
site, complete with rhombics and the large building which formerly
housed the station. He used it primarily for DXing and contests.
End result is "can't fix it because the
parts cannot be had". It is probably easier to restore a 40 year old R-390A
or 75S3 than a 20 year old R-70, if certain parts are needed.
BWAHAHAHAHAHAHHAHAHAHA!!!!
Riiiiight. Try to find a replacement for an R-390 power transformer...
or anything inside that PTO...even in 1980... :-)
There are, in fact, numerous sources for such parts.
Last vacuum tube receiver I DESIGNED and built was in 1964-1965.
HF. Wasn't for listening to on-off keyed radiotelegraphy! [horrors!]
Terrible thing! NOT A LICENSED AMATEUR DESIGNING AND
BUILDING AN HF RADIO! Call out the radio police!
No license was or is required to build a receiver. In fact, no license
was or is required to build an amateur radio transmitter. You'll need
one if you want to hook it to an antenna and transmit though.
It didn't use any "recycled parts."
A pity that you had nothing useable on hand.
