Thanks John and Patrick. Interesting results and a very nice study.
Question---what was your testing method? I can't glean that from the
information below.
Thanks!

Interesting, Zack.
I would ask them about transmitting through the one with the preamp built in.
Can you do it? (i.e., is it RF-sensed/switched)
Or does the preamp make it a receive only antenna, with the accidental
transmission through it smoking the device :) It's bound to happen on a
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

thing I am wondering now is, if I move to SC, would it be acceptable to say

I hate to bring up a sore subject that was a topic of discussion last night,
if the

months,
it's a mute point. Maybe a bunch of us can corner someone at their booth
next

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

You could say you have 500 grids from EN80, and (insert number) from

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, ;-)
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

I have around 74 countries worked from FK78 (puerto rico) via AO-13 and other

meters and some LEO. Ponce is around 50 miles southwest of

For those in Europe we will be operating on all FM sats on Friday under a

Please visit our website after the event for callsigns worked.

I purchased their 440 antenna built a year or so ago and waited forever to
get it. The wait wasn't really worth it in the end and I felt like I got a
better downlink signal with a homebrewed K5OE design. In both cases I used a
preamp close to the antenna mounted at about 20' above ground. I'm now
Excellent! I still recall the pileups on AO-13 from the JA's and DL's when all
I wanted to do was ragchew.
6 meter is my best bet and 2m/70cm from a vertical. So when you hear me the
KP4TR/W4 will be from EL87 while plain KP4TR is from either FK68 or Fk78 (I

One supplemental note on the testing of the Arrow and ELK antennas.
I indicated that having both the transmit and receive antennas in the same

have some advantages.
I failed to mention that having the crossed yagi design of the Arrow isolates

Patrick,
The website is way behind on updates. Jim got #3 and Rob #4 months ago.
I think #5 spot is open. Maybe you, John K8YSE, or some others can lock
it down it the future.
We all appreciate everyone's effort just traveling to that one grid next to
your
home qth that is not very active.
Hi All,
For now, it looks like the PL tone management (and changes to other settings)
has helped to keep AO-51 running and supporting normal operations. We are now
running around 475 mW of power out on 435.300 MHz.
Over the last few days, some of you on the east coast of the U.S. have
