I respectfully request any knowledge on Burst transmitters

[Jay]

I am trying to find any and all topics,schematics, knowledge, or any
helpful thoughts about burst transmitters. I read on a schematics for sale
page that they had pagers with a 3,000 mile range for pocket to pocket
communications using an alpha numeric based type system. My thoughts were
that these had to be some type of burst tranmsitters. I have done all the
google searches and checked all the schematic libraries I can find, but to
no avail. I understand that b.t.'s were primarily "and are still used" for
espionage but I am on hunt now. Thanks for any help

Well... Seems to me that EVERY radio transmitter ever made is a
"burst" transmitter. How long the "burst" persists for is a matter of
design. Everything from milliseconds for RF modems, through variable-
length for commercial and amateur radio voice transmitters, on up
through months at a time for broadcast stations.

'Alphanumeric' in this context refers only to the type of data
transmitted. It has nothing to do with the "system" itself. Any paging
system can transmit whatever kind of signal the paging terminal puts
into it, everything from simple two-tone sequential to the latest Golay
or POCSAG digital modes.

The long-range paging systems you describe are typically
accomplished with large networks of mountain-top transmitters linked by
satellite, phone line, microwave, Internet, or any combination thereof.

I've been in radio communications for 27 years, and I've yet to
hear the term "burst" used in this context. It used to be a seldom-used
term in the radar field, and I recall it was also used in reference to
early data radios ('data burst'), but I've never heard anyone use it the
way you have.

Are you sure you mean what you think you mean?

That page fairly screams "Let Us Scam You!" It's a miracle it
hasn't self-destructed just yet!

Never trust any device where they don't explain the principle
behind it.

As to whether I think I know what I mean, Yes. and no. I was pretty sure
that it was only data transmission, and as for adding whether or not is was
apha/numerical I was just narrowing the search field.
Burst transmitters are still used in modern espionage systems as data
recorder that uses low power transmission propably in ulf range at a very
high transmission rate. Their are currently many type of detectors for just
such transmitters but no info on the transmitter itself. the newest units
B.T.s are smaller and much more reliable. The only places I have seen any
technical info on them were old documentaries on ww11 spy stuff but they
only mention the use of them and what they could be held in.

As for futurehorizons I saw there designs and that's what I am trying
to find out about.

Bursts are in the detector of the beholder!

I guess I answered my onw question there. If any one wants to know what I
found it's at http://swpat.ffii.org/pikta/txt/ep/1216/503/. But thanks for
all the help.

Except that's a bad link.
