I should add that there has been some experimental audio and video being

capacity domestic Australian links. But given that the link is already
completely saturated (it runs at over 497K bits/sec, out of a theoretical

This is a problem it might be possible to do something about. If you can note
exactly when and how long these problems ocurr, pass this information
to me and I will take it up with the appropriate US network operations people.
I will also need to know what your host name/address is in the US. If you
are capable of doing a traceroute from your US host to(wards) the Australian 
host then that would be useful too.

Chris covered the issues here. I should point out that the 512K link has 
been *very* reliable - there have been no outages caused by carrier problems
for months and months (yes I realise this is tempting fate ... :-).

That, and the fact that it's a 512KB link with a minimum load average
of 521KB... 


No it's not a typo.

THE GOSFORD FIELD DAY-AT WYONG RACECOURSE

The GOSFORD FIELD DAY is one of the longest running events in the 
amateur radio calendar.  The next GOSFORD FIELD DAY will be held on 
Sunday 28th February 1993 and this will be the 36th year of this 
popular event.

This coming Gosford Field Day will be held for the first time at 
WYONG RACECOURSE. The change of venue has come about due to the 
need for bigger and better facilities to hold the growing attendance 
and the number of attractions. Last year more than two thousand 
people attended the Gosford Field Day.  As usual the well known 
suppliers of electronic equipment, components and books will be 
attending the event.  These companies will have their latest 
products on display and many will have items on sale at special 
field day prices.    

The organizers, the CENTRAL COAST AMATEUR RADIO CLUB INC. have kept 
the format of the day in line with the changing face of amateur 
radio.  In recent years seminars on a wide range of topical subjects 
have been a popular attraction.  This year an even bigger program of 
topical and interesting lectures and equipment displays have been 
arranged.  Some attractions however have remained unchanged and ever 
popular, among these is the sale of many thousands of new and used 
surplus equipment items known as "DISPOSALS" with many bargains 
going up for grabs.  This year a minimum value of $20 per lot will 
apply. 

Last year the popular "FLEA MARKET" attracted a large number of 
people who traded their surplus equipment to eager buyers from 
trestles, their trailers or from the boot of their car.  The 
organizers expect the flea market to boom with even more vendors 
than last year.

More than two thousand people attended last years GOSFORD FIELD DAY, 
the next one at WYONG RACECOURSE will be bigger and better than 
ever, so mark the 28th February 1993 down in your plans to go to 
the Gosford Field Day at Wyong Racecourse.

I'm considering purchasing a CB radio, mainly for road intelligence.

I am wondering about such things as:

* 27MHz AM vs 27MHz AM/SB vs UHF

* antenna, I'm considering a mag mount on the roof thru my sunroof

* which channels are useful

* jargon

* I've heard rumors that certain engine management computers are
  susceptable to RFI

I'm not really interested in Amatuer Radio as an alternative, because
it will take too long to become licenced.

Thanks, Sm

Methinks if you met me on air on *that* frequency, I might not be operating on
any frequency for a while! Why don't you operate on a real frequency, like
147.000:-)

Er .. I was always under the impression that there was some sort of bungle with
those numbers and they actually started issuing licences with the NAD prefix
and reverting to NAA after they'd all gone ?

Not that it really matters .. whichever way, you were definitely in the first

	Can I ask the date of when you both got your CB licenses ? if
I recollect, I got my licence (NAN something) in  about Jan '78   
not long after this, I started at Nth Sydney Tech and joined their
amateur radio club and went on to get my LAOCP. I guess I just let my
CB license lapse, I only bought a CB to chase 11m dx, I avoided local
contacts where possible.

 David..... the IPS Space & Radio Services sell a commercial programme called
ASAPS (DOS only) which allows you to makelong and short path predictions to
anywhere taking into account the various solar indices at the time, frequencies
in use, antennae used, power levels, sig to noise ratio required etc etc.

Quite a good programme.
