It was a nice theory, but it didn't work in practice because most
AM broadcast antennas, especially at the low end of the band, are
extremely narrow banded. So in practice the only CONELRAD stations
were the stations that normally occupied the two channels. This meant
that they could still be used for navigation purposes by enemy bombers.
Once navigation techniques improved, and ICBMs became the primary
threat, the system was disbanded much to the relief of broadcast
engineers.
The new EBS system is different. It's primarily a defined network
method of disseminating emergency information to the public in a
formal manner. Each area has a Primary station with wireline or
radio links to command authority. All other participating stations
are Secondary and continously monitor the Primary station's transmission.
Note, EBS participation is voluntary, not all broadcast stations are
part of the system. When the system is activated by the Primary sending
a control tone pair, all the Secondary stations' alert receivers unsquelch.
They then determine that proper authenticators are being used to activate
the system, transmit their own alert tone, and rebroadcast all of the
Primary station's transmissions. There are also secondary alerting means
via the wire services' teletype networks, and via the broadcast networks'
transmission facilities. National alerts originate in the White House
communications office. State alerts usually originate from the State
Emergency Management Agency's facilities under authority of the Governor.
Local alerts can be activated by local EMA authorities working under
the authorization of a Mayor or County Executive.
At least that's the theory. Tests of the system are supposed to be
run once a week. In one test, the White House communications office
mistakenly loaded the actual nuclear attack alert tape instead of
the test tape. Very few of the network stations actually activated
and transmitted the attack warning. The broadcast networks didn't
activate the system, the wire services didn't activate the system,
and in the Atlanta area, WSB is the Primary, and they didn't believe
the warning and didn't activate. Those of us at Secondary stations
didn't know about it until the wire services printed a cancellation
notice a while later. If it had been an actual attack, the first
notice the public would have gotten would have been the bright
flash and loud noise. :-(

>GEORGE ATTALLAH-"THE LAST SURVIVOR OF THE GROUP OF ONE"
CONELRAD was the forerunner of what is known as the Emergency Brodacast
System (you have probably heard the occasional test on your favorite
station).
One station in an area was designated as the control station. Other
stations were required to continually monitor the broadcast output of
the control station for an alert tone.
A broadcast receiver in each non-control station was modified to have
its output sent to a tone-squelch detector (I forget the frequency,
but it was probably about 1 kHz). If the control station transmitted
a tone for several seconds (signifying a test or actual alert), the
receivers at the other stations would come alive and ring an alarm bell
and unsquelch their audio. If it was only a test, the monitoring station
would log the time and date of the test in their records. In the event
of an actual Civil Defense alert, however, the stations would immediately
broadcast instructions to their listeners to retune their home radios
to 640 kHz or 1240 kHz for information (sound familiar??). The stations
would then shut down for the duration with only the control station
remaining on the air, but transmitting on the CONELRAD (640/1240)
frequencies.
One of the initial ideas of this system was to minimize the targets
for enemy missile attacks, since the thought was that missiles might
be using radio direction finding techniques to zero in on target cities.
One way this could be avoided was to rotate the control station function
between stations in an area to confuse the RDF - Station "A" would transmit
for a few minutes, then drop their carrier as station"B" came on-line
for a couple minutes, and so forth. Thereby the CONELRAD system.
With the advent of gyro and computer controlled guidance system, the
importance of the CONELRAD system downgraded, and now it's successor's
prime function is informing the public, thereby eliminating the need
for station rotations.
(I still remember running full-tilt from the control room at WBJC in
Baltimore, down a *VERY* long hallway to the transmitter room in order
to determine if there was an actual alert, just a test which had to
be logged, or whether a noise burst or line transient had tripped the
receiver squelch/relay system. This happened about once each night.)

I hang out on 80mtrs...so I'll keep an ear open for you all.
Best time to do this is JUST before dusk...before the mad rush begins.
Don't worry about sig strength ( it's always weaker then and picks up after
sunset...which is about when the whole world gets on)
Watch out for 3700.0 - 3700.7 khz as it's super full of people tuning up
blind, and a commercial station who is deaf.
When the going gets rough, keep repeating..then it's bound to get thru.

The IC-W21AT has two different memory scan modes. One includes
channels marked as "SKIP", the other excludes them. This can be quite
handy at times.
To scan and ignore "SKIP" channels, use the "SCAN" keys, rather
than holding down the "Up Arrow" or "Down Arrow" keys (to select
"SCAN", hold down the "F" key, and press "Up Arrow" or "Down Arrow").

First - try a reset (hold down the memory key while powering up). You will
lose all your memory programs, but it might fix the lock-up problem.
Now - did you drop the '78, or have you been inside it? I have found
that causing pressure on the control board can cause strange lock-up
problems that require removing the battery and re-inserting it. If the
processor is locked, shifting to external power does not help. Power
switching is controlled by (guess what) the processor.
If the reset does not do the trick - send it to Kenwood. They do a good
job of customer support (at least they have for me.) :-)
Good luck and 73.

Oh, no, not this again. :-)
It is unfortunate that hams who take chances like the above aren't
familiar with the laws under which we operate. For example, the Sheriff had
no business confiscating a radio. That is Justice Department jurisdiction.
They most especially had no business confiscating property if they filed no
criminal charges. That is "unreasonable search and seizure". And, ref the
above statement, they can't file criminal charges because violations of FCC
regulations are a Federal prerogative.
Somebody should advise this ham to get a lawyer and sue for the return of
his transceiver. The only regulations violated were use of a
non-type-accepted transmitter on a Part 90 channel, and transmitting without
the proper license for the frequency used. Neither of those violations can be
prosecuted by a local police agency. Also, he could make a case in his own
defense for "emergency" use of the frequency for a bona fide emergency. (He
should have notified the FCC Engineer in Charge of his radio district of the
emergency asap after it happened, to protect himself.)

It is certainly one (sobering) data point.
> Does anyone have any comments?
1. I doubt the sheriff had the authority to confiscate the modified HT.
Probably the FCC could levy such a penalty, but not the sheriff.
Personally I would have asked the sheriff to show me the chapter and
verse authorizing him to confiscate, or for that matter even to
arrest someone for use of a radio on his band. I think he was out
of his jurisdiction on both points.
2. It is legal to modify a radio. It is only the out-of-band use of it
that might be illegal, and then only for transmission (except for
listening on cellular phone freqs). Again, confiscating the HT
seems inappropriate.
3. Has your friend considered making a stink to the media?
4. In an apparent emergency, time matters and it is reasonable to be
conservative -- better to declare a false emergency than to ignore a
real one. Besides, it's a good drill for rescuers. I would have
done the same thing. That's why I carry the radio and why it is
capable of going out of band. In Death Valley National Monument,
for example, the rangers told me their freqs when I explained my
situation (solo hiking) and requested to know them. (It is a bit
unnerving that I can't legally test my ability to reach them, but
so it goes.)
5. Two things I already decided I will do, should the need arise to
transmit out of band in an emergency:
a. State clearly that I'm out of band because it is an emergency
and I have no other reasonable options.
b. Ask "Is it OK if I proceed," or something like that. I know the
dispatcher or whoever is not authorized to grant me operating
privileges, but it couldn't hurt to demonstrate awareness that I
might be causing a problem, and that the other party was willing
to continue.

Ah, I was wondering how this works. (Funny, I don't think Kantronics
advertises that their TNCs do WEFAX.) I have a DRSI DPK-2 TNC, which
is the classic TAPR clone. Is it possible to get Eproms or whatever to
allow it to do WEFAX? MFJ touts the ability of their base-model TNC to
do WEFAX, and I believe it's also a TAPR clone.

Well let's see what my Thorndike and Barnhart has to say about the
matter.
language n. 1 human speech, spoken or written
2 the speech used by one nation, tribe, or large group of
people
3 a form, style, or kind of language; manner of expression:
bad or strong language
4 wording or words
5 the special terms used in a science, art, or profession:
computer language
Following is clarifying discussion re language, dialect, and idiom
appended to the definition of language.
"Language applies to the body of words, forms, and patterns of sounds
and structure making up the speech of a people, nation, or group of
people. Dialect applies to a form of speech peculiar to one locality
or district of the geographical territory of a language. Idiom applies
to a particular language's characteristic manner of using words in
phrases and sentences."
Now let's see what the entry under Morse Code says.
Morse Code, a system by which letters, numbers, punctuation, and
other signs are expressed by dots, dashes, and spaces,
or by wigwags of a flag, long and short sounds, or flashes
of light. (See chart)
So we see that Morse is merely an encoding of alphabet, not a
language composed of words and structure capable of expressing
ideas. There's a footnote near the chart of Morse encodings noting
it's an obsolete form primarily used by telegraphers prior to modern
times.
