Occasionally, I have seen ads in ham classifieds (such as those in 73 or CQ

QUESTION.....
Why has Dural been off air in such a state of emergency?
In this emergency that is affecting so many people in the
northern parts of Sydney, why has the WIA Council
(VK2 Division) kept Dural repeaters off air when there is such
a need for communications in this catastrophe ?
I find it incredible that the Council does not respond to this
emergency and put the repeaters back up as a public service
regardless of the reason for taking them off air.
Pat VK2JPA Broadcast Officer ANARTS
-----------------------------------------
Due to the emergency situation in eastern New South Wales, I
am holding back the series on Guidelines for the preparation
of programs for transmission by Amateur Radio Teletype sent to
us by Frank VK2FJL. This will now commence next week - surely
the fires will be gone by then, and the amateurs back at their
sets ...
Spare a thought for any amateurs affected by this desperate
situation. If many are affected, is there some way we who are
safe can help get them back on air ? Thoughts to this end
would be appreciated. Contact Pat VK2JPA at VK2GJB while
VK2RWI is off air, or drop a fax to (02) 622 9604 during
working hours.
---------------------------------------
Syd, VK2SG, back on air
With the help of Bill, VK2EG, and Bruce, VK2RT, Syd's shack
has been moved into his house to make up for his lack of
mobility and Syd is back on air, except for CW. Be prepared to
hear him on Pactor etc., maybe even a few contacts in
contests, depending on his health at the time.
What Syd does need help with is the chain drive for his quad
which is on top of a 65 foot free-standing tower.The chain has
come off again so he is restricted to a north-east heading. Is
there some energetic person out there with the time and
expertise to assist ? Contact Syd on (02) 631 2576. Tell him
you saw it in the broadcast.
Attention Volunteer Coastal Patrol operators
The Royal Blind Society of New South Wales, in conjunction
with the Maritime Services, have produced a tape which
consists of frequencies, times and weather forecasts together
with ocean conditions, traffic, and many other services which
have reference to shipping operations (including safety) that
are normally broadcast by the Maritime Services (O.T.C.).
This tape has been produced to assist the blind or dyslectic
operators that are assisting with the operations of the
Volunteer Coastal Patrol services throughout Australia. The
tape is a C60 twin track cassette and is available from the
Royal Blind Society of New South Wales for a slight cost.
The tapes are now available, after some delay was overcome.
Please direct all enquiries to Jim Bates at the Royal Blind
Society of New South Wales, phone (02) 334 3333, 4 Mitchell
Street Enfield Sydney.

Subject: Learning Morse - which letters to start?
To: info-hams@ucsd.edu
Will wonders never cease? My XYL asked if there was a class she could
take to get her license just as one was announced on the local 2m net!
The class instructor said he was teaching only the written material
for Codeless Tech license, so I will be the code coach for my wife.
Although I've only had my license about a year, I actually learned the
code in Junior High School (more than 20 years ago). I don't remember
how you go FROM SCRATCH! Seems to me I learned A,N,R,S,E,I,H first, then
W,U,M,O,C etc. Is there a preferred way or order to learn the letters
from scratch? All I have in the house now are 15-20 WPM tapes and a
couple of code programs for Mac for people who already know the code. How
should I proceed? My oldest son is learning by sending "secret" messages
to me with a homebrew CPO. I started him off with the letter groups I
mentioned above, but I am not sure what is best.
Any comments, please post or email!
Thanks,

David,
Try a rolled up J-pole. It's made of 300 Ohm Twin lead and tapped with a
50 Ohm coax with BNC connector on opposite end. It provides about 2.8dB
gain. You can buy the ant from MFJ for about $12 or build it yourself.
The dimensions are below:

I have a 2010 bought a year and a half ago which I'm thinking of selling
because I do not use it enough to justify keeping it.
The radio is like new. I used it some at the beginning, then less and
less, because unfortunately I do not have the time to enjoy it...
There's absolutely no problem with it, it's 100% new condition.
I have everything, manuals, original box, cables etc..
I paid in the upper $300's for it. I have the receipt. I would like
to get $250 for it if possible, given its like-new condition.

I just read what you are looking for, and based on your wish that it
hear spectacularly from 30MHz to well over 1,000MHz, and also function
as a gain transmitting antenna for 146MHz and 440MHz...all the while
not looking obtrusive and marring the natural lines of your pickup
truck...
I suspect you would find better answers in
alt.fountain.of.youth.I.found.it
You are asking for the near impossible, and just a guess, but you
probably don't want to spend more than, say $50..., right?
That is a more difficult quest than the Fountain of Youth or the Holy
Grail... it *IS* the Holy Grail of mobile antennas...
No wonder no one answered... there is no answer... wonder why I
tried...? ;^)

Other than mounting a discone on your vehicle, you would probably best go
with a dual band mobile antenna (ie Larsen 2m/70cm). Since you will
probably not be doing weak signal work, it should suit your needs across
the band fairly well with the worst performance being in the low-vhf band.
If you really need the low vhf, go with a CB antenna for that portion

My PAYING daytime job is as a design engineer for ABC New York. WABC TV is
adjacent to the network facilities, and I believe they get their sync reference
from the network. They did the last time I looked, which was some years ago.
I'll post here if this is untrue. ABC Network uses a Rubidium standard for
sync, BUT, the backup, if the Rubidium croaks, is the crystal oscillator in the
GVG sync generator which is normally locked to the Rubidium. Unfortunately,
the casual viewer has no way of knowing if the Rubidium reference is up.
Most every little two-bit local station now has frame synchronizers these days,
I think the least expensive ones are only a few thousand dollars now. If so,
their colorburst frequency is set by their local reference, and not the
network. Also some cable systems use processing which destroys the burst
integrity. therefore, don't count on this way of calibrating your frequency
counter....
We used to have a Cesium standard on loan from NBS, backed up by TWO Rubidiums,
which we owned as the reference. After the widespread use of frame syncs, the
NBS took their cesium back, and finally the Rubidiums wore out. We talked
about just using the crystal oscillator in the GVG sync generator as the
reference all the time, and in fact have run that way from time to time for
several days to weeks, but we also use the sync as the reference for our clocks
and time-of-day time code (also encoded in the vertical interval and used by
Nielson for ratings measurements), so we decided to spring for the more
accurate Rubidium standard, and bought a new one.
Interestingly, another inaccuracy (really a jitter of sorts) in the frequency
of the colorburst can be caused by doppler effects caused by the satellite
drifting slightly in its orbital position. Almost all TV signals are
transmitted to affiliates by satellite these days. Some day, this may migrate
more to Fiber, but for now it's mostly satellite.
