WICEN.012        SUBJECT:   NVIS ANTENNAS - PART 1/5        17/12/92
 
There has been what can be called more than somewhat mild excitement  in
Northern California emergency communications circles over a form of high
frequency radio propagation.   It's not new, but  I venture to say  that very
few  have used  and understood  it.   "It" is  called NVIS  -- Near Vertical
Incident Skywave.  Patricia Gibbons, WA6UBE, presented a  paper on NVIS at the 
1990 Pacific Division ARRL  convention in San Jose.   It caused quite  a stir. 
 She  quickly ran  out of  handouts and has since received dozens of requests
for more.  The handouts included reprints of articles from military
communications magazines reporting the results of many tests.   Near  vertical
incident  skywave means  forcing your radio signals to travel straight up
(i.e., 80-90 degrees) and back down.  This achieves radio coverage in circle
having a radius of 300 miles and more. Stop and think about that for a moment. 
Complete coverage within such a circle on frequencies between  2 and 10 or  12
Megahertz.  Some  readers may wonder what's so good about this.  So now is a
good spot to say that if only DX (long  distance) is your thing,  skip on and
read  one of the other  fine  articles  in  this  publication.    We  are 
talking  about dependable local area high frequency communications -- the type
we  need for tactical  public safety  communications in  the  Emergency 
Services fields. 
        (to be continued).

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

You expect intelligence on CB? :-)

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

AM: cheap, but full of idiots (in the city anyway - quieter in the country).

SSB: longer range, but more expensive (and hence fewer idiots).

FM: short range (this is UHF) but extended with repeaters (in cities, and
    therefore suffers from the idiot factor again).  More expensive still.

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

A mag-mount THRU a sun-roof?  Or ON the sun-roof?  Go for the big time,
and drill a hole.  Contrary to popular opinion, it does NOT lower the
resale value (although spouses, owners etc may object).

| * which channels are useful

General call channel is 11 (AM), 16 (LSB), 11 (FM), move away after
establishing a contact.  Emergency channel is 9 (AM), 5/35 (FM), and
is monitored 24 hrs/day by CREST (Citizens Radio Emergency Service Team
or whatever).  These channels are mandated by law.  Also, the truckies
seem to hang out on 8, but they don't talk to 4-wheelers.

| * jargon

A pet peeve of mine there, good buddy.  What's wrong with plain English,
and is that a big 10-4, come back there good buddy?

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

According to rec.radio.amateur.misc, Toyota say you should never
use more than 10W in one of their vehicles (I forget which one),
but that's not likely to be a problem with CB stuff.  Anyway. cars
and RF don't get on, when high powers are involved (say, > 20W).

A simple test: borrow a CB hand-held, and wave it over the engine
bay.  If the engine mis-fires (or if the sales-slime blanches) then
pick another vehicle.

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

Rubbish.  Most people do it in a year or less.  Are you in a hurry?
And besides, look at the info you just learned :-)

Incidentally, I'm the proud holder of NAA942 - yes, one of the first
1000 licenced, back when it became legal.  You're considering a CB
licence, aren't you?

Speaking of licences - where does one get one these days? Direct from DOTC, or
can you still get them over the counter at the local PO? Just that I've got
this rig here which I'm thinking of putting in the car...

Sydney WICEN has known about that for ages...  I don't think it had such a
fancy name though.  You laid your antenna along a hedge, and it just fired
straight up and back down within a good local radius.

Oh that sub-band, yes I forgot about that, yes there are some simplex

was more than just 438-439 Mhz !!

The ones I believe are documented in the band plan booklet (available

aside, it was Barry who pointed it out.)

No.  Since the main packet activity is around 439, I would expect the

what packet sub-bands separated by 5 MHz ?
Are you referring to the repeater link frequencies 420-421 and 440-441  ???
aren't they repeaters only ?

Sorry !!...  I was referring to the network connections, the USER level
connections also share the same frequency, well as far as Sydney's concerned.
As pointed out at the forum by youself or John 2ZXQ, that the USER level
to a repeater network node, need only be AX25, the reasons were explained
at the forum.
