I haven't actually seen an IC-2400 but the Nov/Dec 1989 _Icom
Newsletter_ from International Radio and Computers, Inc. [ 751 S.
Macedo Blvd., Port St. Lucie, FL 34983 (407)878-8856 ] describes
mods for IC-2400 which expand UHF coverage 400-479 MHz and VHF 138-174
MHz. There is also a 300 MHz mod, and a crossband repeater mod. Does
anyone know if the IC-2400 in repeater mode will do offsets??
Same issue of Icom Newsletter has out-of-band mod for IC-2GAT (add a
diode, no retuning). A friend did this and his rig now transmits
138-178 MHz.

The notion that an ordinary citizen could assemble unclassified,
publicly available information into a "classified whole" subject to
government censorship was resoundly squashed by the Federal courts about
10 years ago in the Progressive case.
For those of you who don't remember this case, the Progressive was a
magazine that ran articles on the details of how thermonuclear bombs
work. They worked from unclassified sources, with considerable technical
assistance from a guy who knew nuclear physics, but never had access to
classified information. The government attempted to prevent publication
on the grounds that, even though the sources were all public and
unclassified, the collection of that public information into a single
place somehow still represented a threat to national security.
The court threw out this absurd notion, the government dropped the case,
and ten years later the Republic still stands.
This case, and many others like it, have convinced me that the courts
are about the only institution that keeps the US from turning into a
police state.

Did they attempt to contact the owner of the luggage?
If not, that was stupid.
If they did make the attempt, and the owner was not available, not on
the flight, blowing it up was exactly the right thing.

Bill,
Their stand alone modem may be synchronous, but their PC card does not
require any unusual hardware (just a PC from XT types on up). I'm sure hams
are not their market (at $2400 a board). It sound like a really neat device
if you can afford one. My only concern is the possibility of commercial users
straying into the ham bands. Its unlikely but has happened in the past.
Whenever a company markets a product whose main customer is likely to be the
non-ham market, and the product can operate on ham frequencies then there is
a situation to be watched. Note that there is nothing wrong with selling
such a product and it would be great if an inexpensive ham version were
available, but in these days of relaxed ID requirements, it is difficult
to tell a ham generated bust of digital data from a similar commercial burst,
particularly if it uses an unorthodox modulation scheme at high bit rates.
My concern is only to keep a watch out for unauthorized use of ham frequencies
by commercial users. The manufacturer of the device is not, of course,
responsible for such use, but their statement "Use of radio frequencies (in the
range 406-470 MHz) may require prior authorization" is a bit weak.

Hey, stuff it! You've got a perfectly good 'n' key. Use it. Or put parnass
in your kill file. He provides a valuable service to those in the monitoring
community who are interested in whatever might be out there, and I, for one,
would feel a great loss if whiners like you succeed in intimidating him to the
point that he stops posting.

So what is different about cellular - why is it "protected"? It's on
different frequencies, but no harder to receive. In some senses, it's
*EASIER* (higher power, older TV tuners tune it...).
I ask this rhetorically; I know why HBO and cellular people want protection,
I just don't think they have any more "reasonable expectation of privacy"
when transmitting in the clear (or using readily decrypted methods).
