* HOUSTON AMSAT NET INFO *
==========================
The Houston AMSAT Net originates live from Houston, Texas on Tuesdays at
10:00 PM Central Time on 147.100 MHz.  It is simulcast on the Galaxy 3
satellite, transponder 17, on a 5.8 MHz audio subcarrier and is available
for distribution among amateur repeater stations around the country.  The
net is of a technical nature for those interested in satellite, ATV and
balloon launch communications.  AMSAT News Bulletins, SpaceNews, NASA news,
Hints & Tips on working satellites and much more is available every week on
the net.

        I am going to be travelling through the U.S. this summer, and I
already posted a message asking whether my Canadian Amateur license is good
in the U.S. as well, to which the answer was Yes.  Apparently I have to
identify myself with my callsign followed by the prefix followed by "\ <and
then the prefix of the area that I'm in"  How do I know what the prefix
should be?  The ARRL handbook just says that the U.S. callsign prefixes are
between "WAA-WZZ"!

Converting inches to feet is simple, Doug.

1.  Determine how many inches you want to convert to feet.  For
example, 24.  Assign that to the variable, "I".

2.  Determine how many toes are on the value you want to convert: feet.
Assuming normality, for example, you might choose 10.  Assign that to the
variable "T".

3.  You already know the factor for converting frequencies to
antenna lengths, 468, since that was on the ham radio license test.
Assign that to the variable "C".  [Note - this project may be too
difficult for Novice licensees.]

4.  Insert the arbitrary constant 56160 to variable "V".

5.  Compute the number of feet (F) by the formula:
     I x T x C / V  = F

Converting feet to inches is left as an exercise
for the stupi^H^H^H^H^H student.

See how easy the English system is, vs metric?

I'm still working on simple formulas to help you on the
other conversions.  Metrics are harder.

My choice is the self-adhesive felt that is normally used to put
under lamps and things to avoid scratching furniture.  This stuff is
cheap and available at any full-line drug store or hardware store.
While this stuff is much thicker than an acetate sheet, I've rarely
had problems with a Larsen mag mount & antenna blowing off--if
anytime, usually by a semi passing in the opposite direction on a
two-lane road when we're both doing about 60...I mean 55, and when
we're both a bit too close to each other (and the antenna is on the
left rear).  After a rain or two, the felt mushes down, making for
better magnetic hold.

I recently took my tech exam (May 16), and I'm now waiting the long
four months for my license.  However, I moved this week, and I'm not
sure if I should file a change of address with the FCC, or if I
should just wait for the normal Post Office forwarding.  Can anyone
give me any guidance?

Thanks

Pete,

No, unfortunately my news reader deleted the body of this message as I
was posting it.  I am just looking for some people who are as
apprehensive about code as I am who would like to do some on-air HF code
practice together.  I live in Los Angeles, and have an antenna for the
40, 15 and 10M bands, although some of the people who responded on the
net said I should check out the 80M novice band.

I'll second your comments.  Hart's book is pretty good and points out what is
important about building and using small loops.  I took the relevant equations
out of the book and programmed up a TK!Solver spreadsheet (you could do the same
with MathCad or even Lotus) so I could fiddle with different designs.  I never
did get Hart's gamma match scheme to work, so I am now fiddling with the small
coupling loop idea.  I'm using a small vacuum variable cap I purchased from
Surplus Sales of Nebraska to minimize capacitor losses.

>[e-mail]

The answer is 1.  The reason is as follows:

The transceiver is solid state and thus generates the most harmonics due to non-
linear characteristics (this applies to all amplifiers).  So if the
the filter is between the rig and amp the harmonics from the rig will be
attenuated and thus not have any chance to be amplified by the amp.

The second reason is (assuming a tube amp) that the amplifier basically has a
matching network on both the input and output of the amplifier, what you are
doing when you tune the amplifier is matching the output impedance of the
tubes (the amplifier) to the antenna (50 ohms).  Since this tuning process has
a small operating range (also known as bandwidth) the harmonics never make it
out of the amplifier.

Hope this helps.

Herb
