Hello,

I know nothing about short wave radio but I do a lot of backcountry travel
and have been told that short wave is the best emergency communications
device I could have.  So here I am looking for beginner's information.

Is there an FAQ or archive site for this group?  What is a good, up to date,
beginner book I can read?  In what price range is a low end mobil radio unit?

Many thanks for any suggestions!

        I am going to be spending a month in the U.S. this summer (I'm from
Canada), and I am wondering a couple things.  Does my Canadian amateur
radio liscence let me transmit in the U.S.?  If so, will I have to identify
myself differntly?  Please E-mail me if you know anything about these
regulations!  Thanks in advance!

Subject: Canadian Exams --- is four enough
To: [e-mail]

The interested in Amateur Radio has certainly changed with the new exams.
Many new amateurs have studied with the help of a course put on by the local
amateur radio club/association.
Most courses have a high level of hands on demonstration and a high level of
user protocol.

However:  Listening to the new basic license amateurs indicates a need for
    more understanding of the technology they are working with.
    Maybe three written exams could be considered!
ie:
BASIC exam:  As the present one.
         Still 6 metres and up with 50 watts maximum (now 250 watts).
         No packet.

INTERMEDIATE: Now the advanced.  Add more safety, tower installation,
         more antennas theory (concepts) and safety.
         Still 6 metres and up with 250 watts (present basic at
         250 watts).
         Add packet.

ADVANCEDED:  More on high power, repeater control, safety, grounding,
         antennas.
         Power to 1000 watts (present advanced).
         More repeater practical.
         Add packet sysop.

CODE:          These two exam levels  5wpm & 12 wpm seem to be ok.
         The 5wpm gets one started with code.
         Many of the new basic certificates start to work on 5wpm
         within the year.

To: [e-mail]

I posted the clipart question a couple weeks ago and as promised to the
inummerabe people that e-mailed me asking about my findings,I'll make
public what I have found,wich,unfortunatly is not much :-(
The first try was the ARRL BBS's at 203-666-0578.After doing a file
search,I found several ARRL related logos,like ARES,RACES and so on...
Thanks to a fellow ham from the UK who replied me,there is a small
repository of some other radio related ham artwork available via FTP at

hpcsos.col.hp.com,I believe in the /pub/hamradio/clipart area.I found
that the quality of most of the drawings to be quit amateurish and of
low quality,but hey it is better than nothing!
Finnaly but not last,I combined all of this findings into a new files
section of the BBS I run here in DC,Gallery's BBS at 202-298-6009.The
clipart is in the Ham Art file section.
Hope you'll find this info usefull and keep your fingers crossed for
the stuff from the above message to be availale soon :-)

CALL:  N9MWB/AA

ENTRY CLASS: 1B commercial

SECTION / LOCATION:  IN
        Set up on the back porch of my brothers house on a lake in
        Columbus Indiana.

RIG:  Yaesu FT-767GX with modules for 6, 2, and 440.

ANTENNA: 60-70' Horizontal dipole up about 35', 20 meter sloper, twinlead
      j-poles for 2 and 6, and no antenna for 440.

POWER SOURCE: Commercial mains

TOTAL ON-AIR OPERATION TIME: 5-10 hours.  Not really sure as I worked a little,
    water skied a little, swam a little, etc.

TOTAL SCORE:
    4/1   SSB/CW QSOs on 6
    18/3  SSB/CW QSOs on 10
    73/0  SSB/CW QSOs on 15
    38/0  SSB/CW QSOs on 20
    60/0  SSB/CW QSOs on 40
    ----
    193 TOTAL SSB QSOs
        4 TOTAL CW QSOs
    100 watts power
    2 * (193 + 2*4) = 402 points


COMMENTS/LESSONS:

Remember to pay attention to which side of the sloper is up.  The 20 meter
sloper worked much power than the 40 meter dipole on 20.  Also I need to
get a tighter SSB filter to cut through all the QRM.  I never could get
any other family member to operate, although my nephew logged for a brief
while.  Also need a higher location if I want to work any VHF/UHF stations.
Being next to a lake while pretty, doesn't lend itself to line of sight
communication.  Also need to remember to pick up the easy bonuses, i.e.
the ARRL message, and packet/satellite bonuses.

Had a ball!

Is it a little black box that has an antenna input and looks like a modem?  If
so, it is a receiver for Lotus' Signal service.  It receives stock market data
that is transmitted on a subcarrier of a local FM broadcast station and
displays it on a PC.  The bad news is that a password is required to activate
the receiver, at a cost of about $250 a month.

Athos,

I have a TH78 and like it very much.  It has good sensitivity for a HT
and it does  dual-in-band very well.  It is not too bad to
program, but make copies of the manual, and you will be all set.

I have found it to be very versatile and it sounds very good
on the air.

========================================================
Quite a while back I was calling CQ on 29.600 MHz F3E.

An anonymous responder said,"Do you mean CQ or do you really want to say
QRZ?"

He was seemingly quite chagrined that I'd be calling CQ on 29.6 MHz.

I told him that I know what the Q signals mean and that I meant to call CQ
and asked him if he knew what CQ means.

He evidentally didn't know 'cuz he never came back.

Don't have a numeric conversion chart, but there's a chart on
the wall here for the "metrically challenged":


40C - Dang hot!
35C - Really hot
30C - Warm
25C - Nice
20C - A bit chilly
15C - Cool
10C - Cold
5C  - Brrr!

    Bwah hah!  At least some of them got it right, though.

    (I would have e-mailed him, but look at the length of
    that address).

    The original poster wanted to be able to tell someone
    in another country what the temperature is at his place,
    so it doesn't have to be highly accurate, you may as well
    just subtract 30 from the F and halve it.  That will be
    within a degree or two, and anyway, who cares.  If someone
    tells me the temperature in Mongolia, I just make something
    up.  Or do you get an OO notice if you tell someone that
    it's clear when it's actually raining?

    Does anyone ever care what the temperature is 10,000 miles
    away?  Does anyone write it in their log?  Or is it just so
    that you can reply "fb ur temp OM" or "QSL the temperature
    there old man"?   You might just as well tell the other op
    the color of your socks.

    Give 'em a 599 and on to the next one, I say.

    1) Between my HF transceiver and my 1KW RF amp
    2) Between my 1 KW RF amp and my 1KW antenna tuner
    3) Between my 1KW antenna tuner and my antenna
    4) Sell it at the next ham fest

The answer is no.2.  Why?  The HF transceiver and the 1KW RF amp are active
devices and may not be so linear, so bad freq.s could be generated within
which need filtering out.  The 1KW antenna tuner is a passive and (unless you
really mess up) a linear device so what goes in frequency wise should be what
comes out.  Also the tuner input offers the filter a 50-75 ohm output load
which may assist the filter's efficiency.  No. 3 is not so bad a choice
given resonant 50-75 ohm antenna loads, but if you switch your tuner to
shunt or straight through position you arrive at no. 3 anyway.

(2).

Reason:

1)  The harmonics come from the amplifier, and it is best
to get rid of them as soon as possible,

2)  The REAL reason.  Filters are designed to run into
matched loads.  The best filters are doubly terminated,
and are designed to be fed with 50 ohms and run into
a 50 ohm load.  The output of the TX should be 50 ohms
and the INPUT of the tuner should be 50 ohms.

The path between the antenna and the tuner is resonant
but not with 50 ohm terminations.  (If it were, you
wouldn't need a tuner).  There could be huge circulating
currents in the feedwire which the filter is not capable
of handling, and the filter will probably not give
the designed filter characteristics when run into a
non 50 ohm load.

Unless you're prepared to demonstrate the existence of modern-day
virgin birth, or parthenogenesis, I suspect you'd be better off calling
them 'heterodynes' or 'intermodulation products' than 'harmonics'.

Around here they're known as 'lion fodder.'

: See the "=OR="??  That implies if you don't renew and don't tell the FCC

Can you spell "CONTEXT"???
"When a licensee has submitted a timely application....you may
continue to operate until you receive your renewed license or until
you are notified that it was not renewed", at which time you stop
operating.  What part of this don't you understand???

Same thing happened to our Kenwood 440.  Halfway through, the SSB
modulator slowly went bonkers.  Had to switch to an alternate rig.
Could have continued on CW, though.  Geez, maybe CW *is* more
reliable.
