Subject: "Feng Yun"?
Message-ID: <[e-mail]>

Does anyone have information on a Japanese weather satellite called
"Feng Yun"? I found it mentioned in some information from Vanguard Labs
(a manufacturer of WEFAX equipment), but it's just a one-line reference:

    137.85 MHz - Japan - Feng Yun

This and a statement "see what 7 US, Russian, and Japanese Satellites
See" on the cover of their catalog is all I've ever heard of it.  I knew
Japan had a geostationary meteorological satellite, but this one is
apparently a polar satellite.  I'm trying to find out the orbital
elements for it; it doesn't seem to be in TS Kelso's list of NASA
orbital elements, at least not under that name.

In the US, at least, GFI (Ground Fault Interrupter) circuits are only
required in areas where there is a significant chance of contact with a
"real" earth ground.  Outdoors and in bathrooms.  I can understand using
your rig outdoors,.... but in the bath?

Good point.  In the circuit breakers I have seen lately, though, what is
sensed is an imbalance between the two power legs, the assumption being
that the difference goes to ground - through whatever path (not necessarily
the ground wire).  There is no coil in the ground path in US breakers.
A real problem is that of RF getting into the breaker and tripping it.  I try
to use unprotected (no GFI) circuits when I can.

Did I say I didn't think we should be self policing?  I just don't remember
electing Jim Grubs to be the police officer.   In almost every aspect of
everyday life I can make a "reasonableness" test with respect to the letter
of the law vs. compliance.  I have been known to drive faster than 55.  I have
been known to park longer than 1 hour in a 1 hour zone.

The ARRL and Mr. Grubs notwithstanding, ONLY THE FCC has the power to enforce
the regulations - if they wish to.  I guess I don't mind Jim "viewing with
alarm", but he is NOT the authority on the matter, and he is NOT empowered to
enforce his views on the rest of the Ham community.  He should be careful to
state that "IN HIS OPINION" such-and-such is true, but unless he is an
administrative law judge with the FCC, he has NO RIGHT at all to declare that
such-and-such is true.

Most of the privledges we have lost - the Eye Bank - public service at
organized events -- have been because someone like Jim Grubs read the rules,
interpreted them in an overly strict manner, and then went running to the FCC
and forced them to take a stand on the issue.  Its sort of like driving on
the street.  If I go 35 in a 25 zone, carefully, no one will mind (usually).
If I honk my horn, blink the lights and wave, I will probably get stopped for
speeding.

In the case at hand, with respect to compression, anyone working in the field
knows that standard compression methods are NOT encryption, just as the
"scrambler" in a synchronous modem is NOT encryption -- they are just tools
to control the bandwidth and utilization of time-frequency space.  That is,
after all, what amateurs are supposed to do == experiment with ways of
improving the utilization of the radio spectrum.  I do not require that Jim
understand the technology behind this, nor do I require that he participate.
However, he seems to be convinced that he has sufficient knowledge and
authority to make definitive statements on the legality and appropriateness
of any and all actions taken by others.  B******T.

He (and you) can hold any views you want.  You can even air them in this
forum.  Please, just don't arrogate to yourselves the authority to control
the actions of others.

Nobody else responded (possibly because this dead horse has been beaten
into submission), so I feel compelled to.  Consider it constructive
criticism or a flame, depending upon your attitude.

You can not LEGALLY operate a non-type accepted radio (like radios built
for the amateur service) in a service that requires type acceptance.
You must buy a type accepted radio and then also use it in the amateur
bands.  It is illegal to modify your non-type accepted radio AND THEN
TRANSMIT on non amateur frequencies.  Don't do it.  About a year ago,
the FCC issued a stern warning that amateur radio operators were not to
do this.

In the rare case that original ideas   Kenneth J. Hendrickson    N8DGN
are found here, I am responsible.      Owen W328, E. Lansing, MI 48825

That's not an attribute of readers of rec.radio.shortwave; it's an attribute
of all too many readers of Usenet.  And the solution *isn't* to crawl back
into your hidey-hole.

Consider this a re-invitation to rec.radio.shortwave.  Sure, there are flaming
dweebs out there... so what's new?  I've seen some flaming dweebs working
*this* newsgroup too.  And every other unmoderated newsgroup I've read as well.
Ignore them; they're not the only ones out there.
