Yaesu's FT-23R have this "tracking" front-end. They removed it in hopes of
achieving a more sensitive rcvr in the -411 and -470. Ooops. Works great in
the faraday-cage lab, but otherwise.... As reported earlier, they have the
"fix" for this for the -470, just send your radio in to them. Why it's
not a similar repair for the -411 is not clear to me.

Which agencies are responsible for this? Don't they also
monitor long-distance phone conversations, international
mail, etc? How much does this "service" cost the taxpayer?
Incidentally, what is the constitutional basis for the
"National Security" justification that seems to outweigh
all other considerations? Which agencies of the government
have the right to classify different information as secret
and which have the right to review these decisions?

Exactly what are one's rights when communicating over
computer networks? How do they compare to those regulating
intercepts of phone and mail communication?
The only reasonably secure means of E-mail transmission, if
you don't want someone somewhere to read it is encryption.
Therefore I was wondering if it is actually legal to mail
encrypted messages. Does it depend on whether the encryption
scheme is breakable by the government? Does it matter whether
the communication is "in-house" or over "public utilities"?
(I don't know the correct terminology.) Is transmission of
encrypted messages over radio frequencies legal? Is the
transmission of encrypted messages over E-mail sufficient
legal grounds to open an investigation?

Our club station OH8TA has a CDE rotator, but after a storm the
teethwheel of the rotator unit is broken. Does anyone know the address
of CDE manufacturer to have spare parts (Cornell Dublier Electronics).
If someone knows spare parts supplier, please inform us !

Amateur Radio Retransmission of Shuttle Audio/Video
NOTE: This information is unofficial, and its accuracy is not guaranteed.
The Goddard Space Flight Center Amateur Radio Club (GARC) has transmitted,
by Amateur Radio, NASA Select audio on the following frequencies:
75 Meters; 3.860 MHz. U.S. and Canada coverage*
40 Meters; 7.185 MHz. World wide coverage*
20 Meters; 14.295 MHz. World wide coverage*
15 Meters; 21.395 MHz. World wide coverage*
10 Meters: 28.650 MHz. World wide coverage*
AO-13 (AMSAT OSCAR) Satellite; 145.945 MHz. Primary; 145.955 MHz.
Alternate. This Mode B requires a satellite-high gain antenna
*Coverage is dependent on Solar Activity and Ionosphere conditions. With a
good short-wave receiver and outside antenna, reception should be
possible. Due to ionospheric conditions and time of day/night, certain
bands have better reception. A search of each band is recommended.
The GARC plans to re-transmit Shuttle video on Amateur TV for hams and ham
TV watchers in the Washington, DC area. Contacts at GSFC: Russ Jones,
N3EGO, or Frank Bauer, KA3HDO.
The Marshall Center Amateur Radio Club will re-transmit NASA Select audio at
147.100 MHz., 145.1 MHz., and 173.025 MHz. These transmissions can be heard
only in the local Huntsville, Alabama area.
Persons in the JPL, JSC, KSC, and possibly other centers may provide this
service via amateur radio and other means.

..
IF VISITING THE "MILA" (MERITT ISLAND LAUNCH AREA) AT CAPE CANAVERAL,
YOU CAN HEAR LAUNCH, AND AIR-TO-GROUND ON THE K4GCC REPEATER AT
146.94 MHZ. THIS IS A HAM RADIO REPEATER WHICH CARRIES THE "USUAL
INANE HAM CHATTER" UNTILL SOMETHING COMES DOWN THE NASA SELECT AUDIO
FEED. THEN THE FEED OVERRIDES THE REPEATERS INPUT FREQUENCY, AND THE
NASA FEED IS BROADCAST. SO DON'T GET FRUSTRATED THAT THESE RATCHET-
JAWS ARE HOGGING THE AIR, IT JUST MEANS NOTHING IS HAPPENNING YET.
NASA SELECT IS ON 444.3 (NN0V) AND 146.40 IN THE CEDAR RAPIDS IOWA AREA.
FOR THIS MISSION (STS34) IT HAS BEEN ON 444.3 ONLY. WE KNOW OF QUITE
A FEW LISTENERS FOR THIS; ALSO MAY BE ON COX CABLE CH 13 (KTS).

rec.radio.shortwave was created for ALL people who like to listen to
radio communications, from DC to daylight. The original call for
discussion and call for votes posted by Richard Shapiro made it
clear that the group was not intended to be limited to HF, as did
numerous postings during the discussion period. The group is for
all radio monitoring hobbyists. If the scanner enthusiasts want to
create their own group, more power to them, but it would be wrong,
impolite, etc., to chase them out of a group that they were
specifically welcomed in to from day one.

The August 1989 JARL CQ Ham Radio lists the 2SD845 for 260 Yen.
As nearly as I can make out this is from:

New Akihabara Center 16-10
I-chome Sotokanda
Chiyoda-Ku, Tokyo
Telephone (771) 1994 FAX 253-8535
But I don't read Hirekana,Katekana or Kanji so I'm guessing.
