This is the - British Amateur Radio Teledata Group - News Broadcast Service
for all Amateurs and Short Wave Listeners interested in RTTY Amtor, Pactor and
Packet Radio.
This news is broadcast during the first full week commencing Monday each
month, to the following schedule..
Evening transmissions at 1930 GMT. on 3.584 MHz. Mark. +/- for QRM.
RTTY on Monday-AFSK, Wednesday-AFSK, Friday-FSK and Saturday-AFSK.
Amtor-FEC on Tuesday and Thursday.
Morning transmission at 1000 GMT. on 7.041 MHz. Mark. +/- for QRM.
RTTY on Sunday-AFSK.
>From January 1994 the broadcast schedule will be adjusted to provide:
RTTY on Monday-AFSK, Wednesday-AFSK, Friday-FSK and Sunday-AFSK.
Amtor-FEC on Thursday and Saturday.
Pactor-FEC on Tuesday.
An edited version of this bulletin is available on the Packet network as a

News for December 1993. Bulletin No. 012. (all times are GMT).
BARTG information.
AGM.
A well attended meeting again at this venue. The retiring chairman John Barber
(G4SKA) reported on good progress during his term and plans for future progress
to enhance the status of the group abroad. The treasurers report disclosed a
very sound financial position due to the endeavours of a hard working committee
for which the meeting declared unanimous appreciation. The task of updating
Beginners Guides for most data modes is well advanced following the publication
of the "BARTG Guide to Packet" produced by Ian Wade (G3NRW). As contest
manager, John Barber announced BARTG plans for the first world wide HF
Amtor/Pactor contest early in July 1994 which will undoubtedly further the
status of BARTG as the leading data group worldwide. The existing committee
were elected unopposed for a further term with the addition of Andy Matheson
(G3ZYP). The election of a chairman was deferred to the first meeting of the
new committee. Membership subscription is to remain at current levels for the
coming year due entirely to the success of the revenue income achieved by the
individual efforts of the committee serving the membership during the last 2
years. Membership must surely be the best value available for the services on
offer. DATACOM alone is worth more.
Ian Wilks (GW3FSW) volunteered his services to co-ordinate BARTG attendance at
rallies. He will welcome all offers from members available to staff the BARTG
stand at their local rally in 1994.
A very successful meeting to close a very successful year.

Notes of interest.
The station in Sarh, Chad TT8OBO is now being operated by Al (KL7QH).
John in Dubai, U.A.E. is QRV both RTTY and Pactor as A61AF.
The DXCC desk announced that QSL cards from A61AF for operations prior to
August 3 1993 are not good for DXCC credit as operations before that date were
unauthorised. All who submitted cards prior to November 16 1993 must re-submit
as all credits have been removed from the database. Only cards with QSO dates
after August 3 1993 will be accepted.
Prefix hunters will notice the calls YL75V and YL75Z being used to commemorate
the 75th anniversary of the foundation of the Republic of Latvia (18th November
1918). The Latvian buro is not functioning so QSL's may be sent direct as
above.
Thanks this month to..

The ham in question was using a LICENSED transmitter. The transmitter
was licensed under Part 97.5(e), whether it was an IC-02AT, a type-approved
Motorola talkie stolen from a policeman, or an AM broadcast transmitter,
because it was operated in accordance with the FCC Rules (specifically,
97.403) and was a transmitting apparatus under the physical control of
the station licensee.

Ah, but first you have to build it and learn to fly it. R/C modeling is
every bit as complex, in and of itself, as ham radio. Probably more so.
You have to learn to walk before you can run, on this one. It sure is
addictive though.

Why not just set up a telemetry down-link and analyze what comes in later?
Most of the 'live' stuff isn't any more interesting than the recording,
anyway.

Conditions in R/C models are pretty adverse. They pull a lot of g-forces.
The vibration is unbelievable. If you can avoid anything remotely delicate,
do it. Again, I'd go with a raw telemetry link and do the recording on
the ground, the analysis later. Also keeps the weight down.

As long as you're using plain ASCII, you're okay.

Chainsaw and snow-blower engines are fairly common. They make specially
converted models for, um, models. Figure on about a 10-foot wingspan for
one of these beasts, set up for lifting. Get a copy of RC-Modeler or
Model Airplane News, and see the ad for the biggest 'Telemaster.'
But... ...you might want to be a pretty good pilot before you put
this kind of asset in the air. Also, you can easily kill yourself
or someone else with one of these.
>How expensive does the hobby get and how quickly? Before anyone flips out

Funny you should mention credit card... ...basic .40-size trainer with
radio, engine, etc., will run you about $500.00 plus the time to build
the kit. This ain't a cheap hobby. Nor is it really an infant science,
as the sophistication of the modelers and manufacturers is very high.
Also, R/C is very club-oriented, due to insurance and training requirements.
What you MIGHT want to consider is finding a local R/C club and teaming
your temetry interest with one of the experienced builders and flyers.
That way, you wouldn't have to go through ages of practice to start
on your focus of interest. Warning: you will get distracted by the
urge to learn to fly. Second Warning: you will get distracted by the
urge to learn to fly.
Greg
P.S.: Did I mention that you will get distracted by the urge to
learn to fly?

VK2SG RTTY DX Notes for week ending 10 December 1993 (BID RTDX1210)
Bandpass reports this week from the USA were light. Most of the
action was reported from Central Europe.
We anxiously await the announcement from the ARRL of the results of
the vote by the DX Advisory Committee (DXAC) on the establishment of a
DXCC RTTY (Digital) Honor Roll. This vote was taken during November.
Our information this week came from 9X5LJ, I5FLN, the NJ0M Node of the
Twin Cities DX Packet Cluster Network, SP5AA, WB2CJL, ZS5S, and W5KSI.
Thanks to all for your help.

Free space, but a single dipole on a 70 foot metal tower probably doesn't
emulate free space very closely. Getting into calculating the exact
difference is probably a waste of effort. *Measuring* it is the only
realistic way to know what the pattern looks like.

Well we *knew* that. :-) The only serious nulls are off the ends and
that's a small percentage of the total pattern, apparently about 8%
since I deleted end effects completely in my simple model.

If you have an intellectual argument, let's see it. On the other hand,
the 'Political correctness' label is nothing but a label behind which
those who are uncomfortable confronting the issues hide. It's the pat
on the head to the assertive woman, and the 'be a good boy' to the
uppity nigger.

That's right. And it reflects an attitude which is repugnant to many of us
today. 'The American Jew' is from the 1920's. Does that make it quotable
today? (n.b. 'The American Jew' is a work by Henry Ford Sr. which is a
bigoted and anti-Semitic volume. It is catching on in, of all places,
Japan).

Have you ever heard the phrase 'opening old wounds?'

Hmm. If I need a 6CW4 for a project, I reach right over here in this
drawer and pull a new one out of the RCA packaging. You picked a bad
example since I have a stockpile of these to support Ampex VR2000
videotape machines. I may also have the world's largest supply of 6C10s.
:-)
And BTW the '62 volume does have a chapter on semiconductor devices and
their physics. It doesn't cover ICs of course since they weren't yet
available. But really, they're not much more than a block diagram
abstraction of conventional circuitry.
The 1962 Handbook has 624 numbered pages, plus index and advertising
sections. I don't know how many pages my newest Handbook has since it
re-numbers pages at each chapter break, an annoying bug IMHO. It also
has a less than useful table of contents and index. It also seems to
jumble up construction projects and theory instead of offering them in
coherent sections. It seems to be attempting to be a shallow encyclopedia
rather than a coherent guide to radio-electronics as it applies to amateur
radio.
It's true that there are new devices to be discussed in the newer
Handbooks, though the devices used in the construction articles
seem to be discontinued whenever I attempt to build one of the
circuits. :-( However, the electronic theory sections in the older
book are lucid, useful, and more accessable than those in the newer
editions, again IMHO. Basic electronic theory hasn't changed since
1962 even if some of the particular devices implementing it have.
I don't generally consider the Handbook as primarily a source of
construction projects, though I'll point out that older editions
had more ambitious projects. I keep a Handbook around primarily
as a reference volume, and as a reference volume the newer books
are less useful than the older ones. It reads more like a series
of articles for QST than as a coherent volume. (Now if you want
to compare the technical content and quality of the 1962 QST with
today's issues, that's another argument we can get into.)
The new Handbooks have great superficial breadth, but less depth
in fundamental areas. Maybe that's inevitable, but I find them
less useful than the older books, and I find myself turning more
often to other references, such as the RSGB books, or professional
Handbooks like _Reference Data for Radio Engineers_ and its ilk.
The Spread Spectrum Sourcebook suffers from the same fate of appearing
to read like a disconnected collection of magazine articles. On the
other hand, DeMaw's books are coherently written, as are those by
Walt Maxwell and Chris Bowick. They develop their subject matter in
an orderly and concise manner. Of course the Handbook has many authors
of varying ability, and that no doubt leads to it's magazine quality.
Still I think a more heavy handed editor could help bring a bit more
order and consistency to the volume. I realize that isn't an easy job,
and that a particular editor may have a different vision of what the
Handbook should be than I do.
What I want out of the Handbook is a solid theory section that's easily
accessed for reference, and some practical projects that can serve as
examples of the techniques addressed. An example of where the current
Handbook goes wrong IMHO is the rotor control project in the space
communications section. While rotor control is something someone building
a Earth terminal must consider, that project should have been in a chapter
on control systems, a chapter that's missing from the book. I'd also like
a through quick reference section of the appropriate charts, tables, formulae,
and the like that a radio engineer needs frequently. The older Handbooks
did a better job of meeting these objectives than the newer ones IMHO.
