What is the highest radio frequency used for astronomy? Is it3...
 

Unless you own a certain kind of a Radio Scanner/''Radio'', (Joe knows
what I mean) there are some frequencies you and I don't know about.That
reminds me, I needs to look around in UK for what I want and get that
married Irish woman (married to that Irish guy) she is from
Caherconlish,Ireland, he is from Fethard,Ireland. www.fethard.com
I don't think Caherconlish has a website yet) wayyyyyy overrrr there
across the big pond to send one to me.Goodness knows, every six months,
I buy some Maybelline On The Rocks eye liner pencils and I snail mail
them to her.Of course, I would send her the money first for the
''Radio''.

What is the highest radio frequency used for astronomy? Is it 3,438 GHz?

I do know that there have been some very interesting experiments with
nanotechnology, over the past couple of years, in which tiny carbon
nanotubes have been used as optical-frequency antennas.

http://www.nanowerk.com/spotlight/spotid=1442.php has a brief writeup
on one such.


Let's hope, super cheap, super efficient solar panels would be great!
Bye, bye power company ...

I think you need to consider how many watts of sunlight fall on an
acre.

What about some of those Neutron Stars and other thingys in Space that
are spinning around and sending out Frequencies? The whole Universe is
full of many different frequencies.One big giant Radio, the Universe
is.What Frequency did ET use when he Phoned Home?

If he heard an illegal MW transmitter from over 100 miles away I'd say
that's groupworthy, Officer Mike.

I am curious here. At some point you have to switch from metallic conductors

I've heard of X-ray lasers.

This will be buried inside a completely unrelated thread, but there
are lots of "low power",
Part 15 100mW, devices in the MW band. There is a Military Graveyard
just about 15
miles south of me that has such a transmitter for "self guided
tours". I have seen/received
several "talking houses" including a solar powered one that I was very
tempted to visit
under the cover of dark and appropriate for my own use.

I have seen a few billboards with these also. Down toward Tennessee
the big firworks
outlets tended to use them about 8 years ago. I don't know if they are
still in use cause
I don't get down there these days.

Regarding my hunt for the UNID 1640 station rebroadcasting A NOAA
weather stream,
I had assumed by content it was at or near Cave Run Lake, near
Morehead KY. But we
visited there Friday and no signal. I talked to the Corp of Engineers
and they suggested
we check in Jackson. So off we went. As we approached Jackson it was
clear it was
not there. But I decided to check the Jackson Airport/NOAA office to
see what they knew.

They were aware of the TIS stations in Winchester and Richmond that
carried NOAA
and were for use in the event of a nerve agent leak from the Blue
Grass Army Depot
in Richmond, but they knew of no station on 1640. They gave me a list
of towns where there
are low powered NOAA WX transmitters to check and it wasn't in any of
them. On a lark
we went to Richmond Yesterday and the TIS on 1610 is still only
receivable right next
the the emergency center. But there was a different station on 1640.
This one is clearly
connected with the Nerve Agent program and may be in Berea.

Sooner then later I hope to locate both 1640 transmitters.

I will post the main body of this under a new thread.

Hi Tom, we've used plastic lensing since at least the late 60's for focusing
mundane 4-12 GHz radio waves. Dielectric refraction was used back then to
extract additional gain from dish antennas by allowing more even
illumination of the dish without illuminating the area around the dish.
Harris radio had a patent on it.


J.C. Bose used dielectric lenses at 90 GHz back at the end of 19th
century (that is, in the late 1800s) when doing his experiments in Calcutta.

Optical techniques have been used in radio for a very, very long time.
