Hi All,
I have an ?out of the blue? question that hit me the other day since I am a
freshmen in college and will likely move away from home sometime in the next
5+ years... I know the VUCC rules say you can count any grid towards VUCC
that was worked from two locations no more than 120km apart. Lets say I
have 500 grids worked by the time I move out (which is a LOT of time, work
and $$), and I decide to move to SC. Are those 500 grids that I
worked/confirmed no longer valid towards VUCC (if I wanted to get an
endorsement)?
73!

Actually, the limit for the maximum distance between the locations you use
for satellite VUCC is 200km, or approximately 124.2 miles. See section 6
in the current VUCC rules at:
http://www.arrl.org/files/file/Awards/VUCC%20Rules%202011_Rev%2020110215.pdf

If your location in South Carolina is more than 200km from all locations
you are currently operating from and using toward your current satellite
VUCC, then the South Carolina location could not be used toward your
existing satellite VUCC. You would have to start working on a new satellite
VUCC based on your new location in South Carolina. You would still maintain
your existing satellite VUCC award, and could add to it if you operate from
other locations that would fall within the 200km limit for that
satellite VUCC.
This probably isn't the answer you were looking for, Zack. Then again, you
would have a new challenge to work stations from a new location further
east than you are now.

Hi Patrick,
Your response does confirm what I thought the answer was. I guess the only
thing I am wondering now is, if I move to SC, would it be acceptable to say
I have 500 grids confirmed, or should I say 0? VUCC is one aspect of it,
but how about the day to day grid collecting. Since it would not be counted
towards an award, I do not see an issue with that, as long as you keep track
of what grids were working in OH and which ones were worked in SC.
I also know it is 200km - I was confusing it with 124mi. ;-)
BTW, I am not considering moving to SC (no offense to SC residents). If I
had to move somewhere other than OH it would be CO.
Thanks for the response!

Gentlemen
Great work,very informative. As I read the article I wondered to
myself how my homebrew portable satellite antenna would stack up ? The Tape
Measure Beam. I don't expect any results, as one could spend a lifetime
analyzing everyone's homebrew antennas. But topics like this it just goes to
show that there are many many options and some at little expense to get on
the birds.
Great Job 73 KC?BMF John

Hi Zack and Patrick,
I hate to bring up a sore subject that was a topic of discussion last night,
if the
ARRL doesn't start confirming everyone's grids submitted over the last six
months,
it's a mute point. Maybe a bunch of us can corner someone at their booth
next
month at Dayton that will communicate their intensions.
73 and get that 500!

Zack,
Other things to consider before moving to CO:
- your WAS award will only count for contacts made from OH
- your DXCC award will count from anywhere in the lower USA
- your WAC award will count from anywhere in N.A.
- your WAP award will count from anywhere on Earth

Hi Mark!
> Thanks John and Patrick. ?Interesting results and a very nice study.
You're welcome!
John and I talked about doing this a few weeks ago while at a hamfest. John
called me Saturday morning, and asked if I was free in the afternoon. I went
over to his house in the early afternoon, and we turned his front yard into a
testing field for antennas for an hour or so. :-)
> Question---what was your testing method? ?I can't glean that from the
information below.
On the west end of his front yard, John set up an IFR-1200 station monitor
with a long 2m/70cm duckie as the transmitter. The antenna was either a
Diamond RH77CA or the MFJ equivalent. I may be able to figure it out from
the photos I took, or John can jump in and answer that. On the east end of
the front yard, he had his Icom IC-910H satellite transceiver as the receiver
along with an RLC Electronics switch attenuator:
http://www.rlcelectronics.com/index.php?option=com_content&view=article&id=102
:vhf_precision_switch_attenuator&catid=12:attenuators&Itemid=5
between the antenna and the transceiver. John set the station monitor so
it would transmit a signal that could be attenuated for an S-9 reading on the
IC-910H. We used a large cardboard box to hold the antennas, pointing
them toward the station monitor across the yard, and switching levels of
attenuation with each antenna to have an S-9 reading on each band.
The PortaFox antenna John mentioned is a log periodic designed and
made by Michael Brennan KA6PGN, based on the Elk Antennas log
periodics. He had these antennas on display, along with lots of military
radios, at the Palm Springs (California) hamfest in late January. He also
visited the Yuma (Arizona) hamfest in February, where he sold me the
antenna with elements to make it work either as a monoband 2m antenna
or as a 2m/70cm antenna. The elements are just like those Elk Antennas
uses with their antennas, thicker than those on an Arrow Yagi.
My PortaFox has a length of coax from the feedpoint at the front of the
antenna inside the double boom to a BNC connector at the rear. This is
similar to how I run coax from my Elk through the PVC handle toward the
rear of the antenna, but Michael has done in in a more elegant manner
with the PortaFox. Other PortaFox antennas Michael had came with a long
length of coax from the feedpoint, and you could put your preferred coax
connector on the other end.
I have lots of pictures from this antenna test at home, and will post them
somewhere tonight once I scale them down a bit for the web. The photos
are 12-megapixel photos from my mobile phone's camera.
As for KK0SD's comment, yes - I remember WA5VJB's article in CQ VHF
where he mentioned insulating the elements on an Arrow Yagi from the
boom. He also mentioned he had some ideas to increase the gain from
an Arrow Yagi, but (as far as I know) this follow-up article has never been
published.

You could say you have 500 grids from EN80, and (insert number) from
(insert other location). You'll be able to say you have satellite VUCC,
along with any other awards, regardless of where you were and where
you are now,

QSOs made outside that 200km limit would not count for your EN80-based
satellite VUCC, but could count for a new VUCC somewhere else. You would
just have to keep track of which grids you worked from each location.
Other awards have other limitations. K5OE mentioned some other awards in
his recent post.
> I also know it is 200km - I was confusing it with 124mi. ?;-)
I thought that was the case, but wanted to ensure we were referring to the
proper limit for a satellite VUCC.

If you travel a lot to some other location, you could attempt to get awards
like a satellite VUCC away from home. I am gradually doing that for northern
Baja California as XE2/WD9EWK and Vancouver as VA7EWK. I know it will
take more trips to both places (and, for Mexico, more contributions to the
Mexican federal treasury every time I get a new XE permit) to get 100 grids
confirmed. For a Phoenix-based satellite VUCC (whenever that application
is ever processed), I know I can operate from portions of 6 grids including
the
city park on the DM33xp/DM43ap grid boundary I typically operate from and
remain within the 200km limit. Other road trips are for the enjoyment of
working stations and confirming QSOs with those stations, even though I
can't count the QSOs toward a Phoenix-based satellite VUCC. Then again,
if I accumulated confirmations for 100 grids from places like DM31, I could
apply for another satellite VUCC for that location.

I have thought about doing the reverse VUCC. I think that is the correct
name. I think I will slowly work towards that, but my main enjoyment from
portable operations is getting to confirm to new grids for others, along
with sightseeing, using new equipment, meeting weird people, ;-) designing
QSLs, etc.
Anyhow, thanks for all of the replies everyone. This answers my questions.
73!

You could say you have 500 grids from EN80, and (insert number) from
(insert other location). You'll be able to say you have satellite VUCC,
along with any other awards, regardless of where you were and where
you are now,

QSOs made outside that 200km limit would not count for your EN80-based
satellite VUCC, but could count for a new VUCC somewhere else. You would
just have to keep track of which grids you worked from each location.
Other awards have other limitations. K5OE mentioned some other awards in
his recent post.

I thought that was the case, but wanted to ensure we were referring to the
proper limit for a satellite VUCC.

If you travel a lot to some other location, you could attempt to get awards
like a satellite VUCC away from home. I am gradually doing that for
northern
Baja California as XE2/WD9EWK and Vancouver as VA7EWK. I know it will
take more trips to both places (and, for Mexico, more contributions to the
Mexican federal treasury every time I get a new XE permit) to get 100 grids
confirmed. For a Phoenix-based satellite VUCC (whenever that application
is ever processed), I know I can operate from portions of 6 grids including
the
city park on the DM33xp/DM43ap grid boundary I typically operate from and
remain within the 200km limit. Other road trips are for the enjoyment of
working stations and confirming QSOs with those stations, even though I
can't count the QSOs toward a Phoenix-based satellite VUCC. Then again,
if I accumulated confirmations for 100 grids from places like DM31, I could
apply for another satellite VUCC for that location.

Mark, The testing method for the antennas was fairly basic. The antenna
range was my front yard, the
only easy location free of obstructions, other than a public park. Our
signal source was an
IFR-1200S station monitor feeding an aftermarket dual band rubber duck
antenna vertically polarized
and about 3 feet above the ground. The antennas, vertically polarized for
the band being tested,
were supported one at a time at about 44 inches above ground by resting
their boom on the top edges
of a large cardboard box positioned about 93 feet from the station monitor
across the front yard.
The receiver for the tests was an IC-910. The signal level was set on the
station monitor to produce
a mid scale, S9 reading on the receiver S meter. An attenuator was used at
the receiver input to
reduce the signal so that the addition on 1 db attenuation would cause a
single step reduction in
the S meter bar length. We used the Arrow antenna to establish this
reference level against which
each antenna could be measured. Each antenna was then tested to determine
how much attenuation was
required to match the signal to the reference level. With the PortaFox, the
signal strength was
below the reference level on 435 MHz, so we had to create a new reference
level for that antenna. We
then used the Arrow antenna and measured how much additional attenuation was
required to get down to
the signal level of the PortaFox antenna. The difference between the amounts
of attenuation required
to match the reference level indicate the relative performance of the
antennas. John Kopala N7JK

I have around 74 countries worked from FK78 (puerto rico) via AO-13 and
other modes but that stopped in 1998 when i moved to florida. I recently
installed a remote control station in Ponce PR which is in FK68. I will be
able to work 6 meters and some LEO. Ponce is around 50 miles southwest of my
old QTH. Am i zero for VUCC as well?
