I used to use a 5/8 mounted on a plate on a rear carrier. It worked quite
well. You will need a large batter for power or your time will be linited.
I would get one of the vox capable hts and you are going to have fun
getting a headset to work with a helmet. It is a blast though. It tests
your conditioning too. My voice would change a little into the wind up a

Anyone have a feel for how long licenses take to get from FCC Gettysburg?
Last I heard it was 10 weeks :-(

I passed my Tech this morning ( and bought some code practice stuff :-)
The VEC said (jokingly, I hope!) that I could be up to 20 wpm by the time
I see a license.

Good Luck!  I took my exam back on Feb. 12 in central Illinois hoping to
get my callsign by Hamvention (Last weekend in April).  I have heard recently
that some ppl have waited up to 13 wks for there callsign.

Still hoping to get it in time

No, it's half that amount. FM and TV tolerance is +/- 1000 Hz, AM is
+/- 10 Hz. As to your latter comment, don't bet on it. The rules now
only require checking frequency once a month.

He probably won't know. Ask for the operator on duty, he can give you
moment by moment readings off his display, if he still has one. Note
that FM broadcasters only have to maintain a tolerance of +/- 1000 Hz from
their assigned frequency.  Note also that their assigned frequency may
have up to a 10 kHz offset from normal channel center if they're close
spaced with another station. So *ask* what their nominal carrier frequency
is, don't assume its the nominal channel center.

The same goes for TV broadcast. Note too that we aren't required to
maintain a Type Accepted frequency monitor anymore, and only have
to have our transmitters checked once a month for compliance to the
+/- 1000 Hz rule, sometimes with an Opto counter. :-(

Go with zero beating WWV.

No. All you need is a low pass filter in the PLL error loop with a
cutoff of less than 10 Hz. Since many transmitters *modulate* the
transmit VCO, there's no point where you can get carrier without
modulation in the transmitter. This is the same way your synthesized
2 meter HT works. It doesn't have a narrow bandwidth filter to
"pick out" the carrier either, just a low pass response in the error
feedback network so it smooths out *long term* frequency error, but
not the audio modulation.

SB SAREX @ AMSAT $STS-59.009
SAREX Update & Keps 4/10/94

Greenbelt, MD, April 10, 1994 at 16:00 UTC

After the successful check pass yesterday, the SAREX Working Group has had
several reports of packet radio operation and some general voice QSO
operation during the Shuttle passes over the U.S.  In addition, the
St. Bernard High School in Playa Del Rey, CA had a very excellent school
group pass this morning (Rev 19).  A total of seven questions were asked
by the students.

The official SAREX element set for today will be GSFC-007.  This
element sent was generated by Ron Parise, WA4SIR of the Goddard Space
Flight Center.  Gil Carman, WA5NOM reports that the predictions using
GSFC-007 differed from JSC-009 by approximately 20 seconds.  GSFC-007
follows:

 NOTE - This element set is based on NORAD element set # 007.
        The spacecraft has been propagated to the next ascending

Oh well, at least it makes a change from the usual 'unknown host' problems.
Catch is, you can 't send him an email to tell him his mailbox is full :-)

Hello again, Jeff.  My point is that one cannot change the gain of an
antenna system without changing the radiation pattern.  In that
process, while Hawaii may enjoy an increase in signal level,
Arizona may suffer a decrease in signal level.  Who's going to
be forced to suffer because of the antenna system change?

Subject: WWV Antennas
To: [e-mail]

I think that people are applying 2-D thinking to a 3-D
world.  There are two main ways of getting "gain", both
of which involve concentrating power in one direction
at the expense of another.  WWVH uses what is known
as a broadside or endfire (can't remember which it was
from the description) array of vertical dipoles to create
a pattern, which when viewed from above, appears to
concentrate its power to the west.

However, there is another way to concentrate power, which
is what most FM broadcast stations do.  If you look at
a single dipole vertically oriented, you will see that it
has a omni pattern viewed from above.  Fine.  If you
now view it from the ground, a lot of power goes up into the air,
some of it at nearly 90 degrees to the ground.  (An ideal
dipole has a null at 90 deg.)  Now, recall what you learned
about HF propogation.  Power that is sent nearly straight
up has a much lower chance of skipping (being refracted) than
one with a low angle of incidence.  Thus, that power is most likely
being wasted.  A stacked dipole of proper phasing (two dipoles
on top of another) can use constructive interference to put more
power closer to the horizon rather than up in the air.
This puts more power into the low angles of incidence which are
much more likely to be refracted and/or reflected back down
to earth.  Note, however, that the omni pattern as viewed
from above is NOT disturbed.  This is how one gets "omni"
gain.  FM broadcasters do this to put as much power as
possible into the horizon.  Not much advertising potential high
up in the air.....

Around here, I am unhappy to report that there are a lot of stations that
just barely meet the +/- 2 kHz requirement and at least one that doesn't.
(Admittedly one of them is using a 1952 vintage RCA exciter that was designed
originally for the 40 MHz band, which RCA resold as an 88 MHz exciter by
replacing the final 6146 stage with a frequency doubler, and as a result
the drift is multiplied).

Most of the stations out here in rural VA don't have engineers on-staff
any longer, and they only fix things when they become catastrophically
broken.  This does not tend to result in the best quality signal making
it out over the air.
