Subject: 6 Meter Transceiver Advice ? ? ?
To: info-hams@ucsd.edu
I am interested in getting a pair of used 6 meter transceivers for my
father (KD4BWR) and myself; he is a no-code tech and we will use them for
scheds.
Would like to know what would be a good, economical choice?
Thanks, in advance, for the advice!

Has anyone on this alias been following the developments

Nabil, thanks for the 7X listing. Can you get addresses

Tunisia last year? I have his card, but we need a copy

Can you help with this?

This ham believes that any _ham_ can use any radio on any frequency
to report an emergency situation and request aid, according to 97.403
and 97.405. My old copy reads:
S 97.403 Safety of life and protection of property.
No provision of these rules prevents the use by an amateur station
of any means of radiocommunication at its disposal to provide essential
communication needs in connection with the immediate safety of human life
and immediate protection of property when normal communication systems
are not available.
S 97.405 Station in distress.
(a) No provision of these rules prevents the use by an amateur station
in distress of any means at its disposal to attract attention, make known
its condition and location, and obtain assistance.
(b) No provision of these rules prevents the use by a station, in the
exceptional circumstances described in paragraph (a), of any means of
radiocommunications at its disposal to assist a station in distress.
I read this to mean that, in a real emergency, it's not illegal for me
to transmit 1 megawatt over the sound carrier of a TV channel in order
to get help, much less 5 watts to communicate with the Sheriff, provided
there's no other way to communicate.
The text of 90.47(a) given in the Newsline text doesn't seem to me
to _prohibit_ anything, it seems to _authorize_ persons (not just amateur
radio station license holders) who have a need for emergency communications.

I don't know why you're shocked to see the C=64 as a mainstay in Packet.
There is no need for wizz-bang horsepower, just to print little characters
to the screen. In fact it was innovation by some programmers in Germany
that brought us the Baycom TNC. If this isn't an application of high tech
( relatively speaking ) what is. It may be old, and not the latest technology,
but that in itself doesn't make it useless. If you want all the latest "
Bells and Whistles " Ham Radio can be expensive. If you want what works, and
are willing to expend some effort and/or elbow grease, Ham Radio can be
quite reasonable, while still being innovative.

I've had good results from putting a sheet of kitchen wax paper

lift removal technique instead of the drag-across-the-roof one.
Beware that anything between the antenna and the roof will decrease

antennas for everyday use.

On the other hand, where is the compelling need for amateurs to transmit
beyond the terms of their licenses on frequencies allocated by the FCC
to public safety agencies? Why do so many hams feel that they have an
absolute right to any piece of spectrum at any time? If the commercial
interests felt the same way, there would be no amateur bands left for
you to escape from. Let's try living within the limits and doing
something positive for "the public interest, convenience, and necessity"
before the FCC or Congress get wise and give all the spectrum away. KB

Someone here posted a comment to the effect that it would be bad if the FCC
issued a regulation prohibiting transceivers that could be "easily modified"
to transmit out of band. The apparent opinion was that this would intrude on
hams "rights" to have such capability available to them in emergencies. I
suppose that the poster also thinks that there would be a large and vociferous
protest from the ham community if such a regulation would ever be proposed.
In response I say, "Where was the ham community when the FCC was compelled by
Congress (at the behest of the cellular phone industry) to promulgate a
regulation that will terminate the manufacture of the Icom IC-24AT and similar
transceivers?"
Why, you ask, is the '24AT et al an endangered species? Because they violate
the new TDDRA and can be "easily modified" to receive cellular telephone
calls. Folks, we are already riding down the "slippery slope" to the end of
hobby radio as we know it.

Subject: SE Michigan Fox Hunt -- 18 DEC 93
To: info-hams@ucsd.edu
The Radio Active Communications Club of Southeastern Michigan (RACC)
will be holding its monthly fox-hunt on Saturday, December 18, 1993.
The starting point for the December RACC Fox Hunt will be at Grosse
Ile High School, on Grosse Ile in the 'Downriver' area of Wayne County.
We'll be meeting up at the Elias Brother's Big Boy restaurant on Fort
Street at Sibley Road in Riverview starting at about 10AM. Grosse Ile
High School is a few miles away.
As usual, the 2-meter beacon will start transmitting at Noon, and
all teams must start off from the school parking lot. This hunt should
prove to be one of the more challenging ones put on by the RACC, so RDF
novices are encouraged to try to team up with other individuals who might
have more experience and equipment! Each RDF team must have at least two
people, & you should plan on a combination of mobile RDF'ing as well as
searching or 'sniffing' on foot.
To get to Grosse Ile High School, you'll want to take Grosse Ile
Parkway from Jefferson Road in Trenton over the (free) bridge onto Grosse
Ile, continuing east on Grosse Ile Parkway until it ends at River Drive.
Make a left (head North) on River Drive, and the H.S. will be on the left
about a half-mile down.
Talk-in to the restaurant & Fox-Hunt starting point will be conducted
via the N8IQX repeater on 224.580MHz, with a simplex link on 147.495, or
the K8SB Wyandotte Repeater on 147.240 (+).
For further information & possible updates, please tune-in to the
Radio Active Communications Club's Monday Night Nets, at 8PM on 224.580
or the 147.495MHz simplex link! You can also log on to the RACC packet
mailbox --RACC-- on 145.03MHz, located in the Garden City area to check
for updates.
If you'd like to participate but don't have your own team lined up,
mention this during the RACC Net & others should be happy to have you
help them out on the 18th.
GOOD LUCK, and we hope to see you there!
This Fox Hunt will be the joint product of the cunning,
sadistic minds of N8NQN, N8NYK, and KA8VIR.
Tim, KA8VIR

This is incredibly wrong.
(a) When you increase power you simply emit more photons of the
same energy, and they follow the same paths as the smaller
number of photons. The only way you change the energy of
a photon is to change the frequency of the corresponding wave,
and indeed waves of different frequency follow different paths
in the ionosphere, but that's not what we are talking about.
(b) What's really happening is that the powerful trransmitters send
the photons faster and harder, so they go further. The Heaviside
Layer has nothing to do with this, it is a variety of chicken.
(c) One of the above paragraphs should not be taken seriously.

FM rigs are limited in range? Sporadic-E clouds do a nice job of
refracting 6-meter FM signals. One of the first 6-meter QSL cards I
received was for an FM QSO from Massachusetts to Florida (150 watts
and 3-element Yagi at 30 feet on my end).

Crosley also made a lot of smaller transmitters, but back in the days when
everything was plate modulated, even the smaller transmitters were pretty
large. There's a daytimer in NC that is running a 2KW Crosley... the
modulation transformer sits on the ground and comes up to my waist. Sounds
very nice, though, especially when you consider that it was built in the
mid-30s. Wish that our 1985 vintage Wilkinson was as reliable....
