Hi!
On Saturday, 22 November, I am planning a quick road trip to grid
DM22 in southwestern Arizona. DM22 is another grid that is not heard
very often on the satellites. I am planning to work the afternoon
and evening passes on AO-51, SO-50, and - if it is still on the air -
AO-16 from out there. I may try to park on a grid boundary to be in
two grids simultaneously (DM22/DM23 or DM22/DM32), but the main focus
of this road trip is to put DM22 on the air for a few passes.
If you make a contact with WD9EWK from DM22 and want a QSL card,
please e-mail me directly with the QSO details. If you are in my
log, I will be happy to send you a QSL card.
73!

I'd also like to thank the efforts of the Field Ops Co-ordinators that
do the "right thing!" I cannot tell you guys that personal upfront
eye-to-eye contacts is a good thing. I'd like to know if any of you
did an impromptu type of survey on satellites and type of orbits- bands
ops would like to see - what AMSAT can do to attract membership.
Anything? I have been at many hamfests and like to get info from the
people walking by and asking questions that may be beneficial to our
group's future plans.
Would appreciate any info you can supply with this area in mind.
Thanks,
Dee, NB2F

PCSAT-1 should return to full operations on 9 Dec 08.
Plan on another Satellite Simulated Emergency Test.
This should give a few weeks for some good 2m packet contacts
and the SSET, and if the ISS is also operational on 145.825,
then there is the possibility for some lucky 2-hop DX contacts
via both birds. Combined, that is 12 opportunities per day for
contacts without any change in the radio.
Operating PCSAT-1 is just like any 1200 baud 2 meter packet
repeater. Uplink and downlink are on 145.825 and the path is
VIA ARISS. This path is identical to the ISS path so that you
do not have to change anything between the two spacecraft.
(Until PCSAT-1 is reloaded, however, its digipeating alias is
its FCC call W3ADO-1.) You can hear it every day, but its
packets die before completion because of poor power budget.
I just commanded PCSAT-1 yesterday and all functions are normal.
All we need is the first full-sun orbit on the 9th of Dec to be
able to do a full recovery; and then it should last for 2 weeks
or more.
You can easily operate mobile using any of the APRS radios as is
(D7, D700, D710, VX-8R, DR-135), or any other radio with an
external TNC, or even any radio with no TNC if you use a
sound-card packet application.
You can make two-way contacts, send beacons and bulletins and
send your position so you will show up on the PCSAT web page
http://pcsat.aprs.org
I'd suggest everyone plan on testing their emergency Email
capability during this time. Lets set the time window of 12 to
15 December for everyone to try to send an Email via one of
these birds. Please see the Satellite Simulated Emergency Test
www.aprs.org/sset.html. You can use any packet system and no
special software is required.

I am a user of an Arrow II handheld yagi. I am also very impressed with it's
performance. Has anyone attempted to weatherize it for permanent outside tower
use? Seems a little Loctite on the element threads and some shrink wrap around
the BNC connectors, pull the foam handle and mount it.
Anyone try this?

Exactly right Jim. I did everything except the loctite and had mine up for
over a year on a TV rotator. I just screwed the elements together as tight
at I could with in reason. Some of the FM birds will have unsatisfactory
passes from time to time as you can't adjust for polarity or give the beam a
little twist of the wrist. So you will get some fading from time to time .
Sometime you might be deaf for half a pass. But that experiment was enough
to get me hooked and upgrade to a cross polarized and switchable antennas on
AZ/EL rotators.
BTW, I bypassed the built-in duplexer and ran two feed lines when the handle
was removed i.e removed the foam handle and duplexer and shrink wrapped the
BNC connectors. We have -40C to +40C weather here and it survived okay.
The only way you know something odd happened to my arrow is the wear and
tear after a year on the elements in that the colored speckles on the top
side of the arrows faded to the pure aluminium. It's now back to field day
and demo use with the foam handle reinstalled.
I even added a DIY elevation control rather than fixing it at about 30
degrees by using an remote controlled electric auto mirror assembly picked
up at a local surplus supply house for about $5 plus a bunch of PVC plumbing
stuff from Home Depot.
http://picasaweb.google.com/ve4yz.alan/ArrowWithAZELRotator#
However, now that I have a couple of KLM's on a Yaesu G5400b with Landwehr
preamps...well, there is no comparison. I think that sooner or later
everyone comes around to understanding the importance of good antennas and
feed line and installed the best you can afford. I appreciate that budgets
and physical location sometime will prevent an optimal installation. My
KLMs are shorted to they clean my roof, but, that is for another discussion.

Heh. I think handheld operation is the best, especially if you get a
couple of good clear passes and AO-51 in QRP mode. While I'd like to
have a whole load of steerable aerials and all the goodies, standing
there with a handheld and a homebrew cross dipole just seems more
hardcore ;-)

Thanks for the positive feedback from all. I'm not looking for a 'killer'
antenna, just something small but more efficient than the Cushcraft A270-6
that I am currently using. I have it fixed tilted at about 25 degrees atop
my 33' foot 'pole tower'. I made some modifications to the feed part of it
and retuned the gamma matches and it works OK, not great, but OK. I'd like
to replace it with something with a little more gain on 435. It works very
well on 145.
I'm either going to clone the Arrow (VE2ZAZ's clone) or buy a bare Arrow
and weatherize it. Got all winter to ponder it.
And yes, Jim WA4IVM, guess we are a couple of old fogies...
Looks like we both got our tickets in the same year, and got retired the
same year. 30 years with IBM and 6 years in other places as a consultant was
enough for me. Glad that part of my life is over.
Thanks again for all the comments and 73 ...
