>Drew's Evil Twin ??
That would be KU4OS. Or more correctly I am -his- evil twin (the one with the black beard, sash, and dagger).
Back to P3E. I like David's idea. I'd like even more to hear something similar from Peter or Hartmut. I've donated to P3E in the past, and voted as a BOD member to help fund their lab out of the -NA reserves several years ago. I love the project, but until I hear a little more positive about what's currently going on over there, my money will continue to go to Kiwisat, FunCube, and first and foremost, Fox. I am the proud sponsor of a solar cell on Fox, and hope to be able to do more this year.
Have you heard we find out if we (AMSAT-NA and Fox) get one of the NASA launches on Monday?

Got this from the IGate manager. Thanks to all who provided the pieces and
clues needed so track this down.
Subject: Re: I-Gate
I see what happened. RK3KPK is a BBGATE user who frequently
telnets or netroms
into BBGATE. He's a curious follow who stumbled across the gateways
RF port servicing the APRS packets on 144.390. That port has not,
yet, been restricted. So, when
rk3kpk checked the heard list on the port, he thought there were lots
stations available for contact. Ergo, he attempted to initiate a
connection in hopes
of chatting with a 'local' laptop or tnc. There's nothing clandestine
about his activity.
If anything, it's my bad for leaving that RF accessible to the
general ham community. As it turns out, I believe he as been the only
user who actually tried going out on
that port to connect with INDIO or any other station listed on the
APRS port heard list.
Good catch guys.
Let's clear the decks on this one.... you posted:

Let's correct one glaring error in the statement above...
MINIMALIST <> MEDIOCRITY
(yes, I capitalized both words intentionally)
One can go with a minimalist station, and not have something that is
mediocre. You can push the envelope, without having to build or buy
a fully-equipped station, complete with a satellite-ready transceiver,
computer control, long-boom Yagis, an az/el rotator, and even
preamps. Also don't forget operator skill. Without that, the fully-
equipped station could be mediocre. Until we get an HEO satellite
in orbit, a minimalist satellite station can work just as well as the
I've said it many times on this forum. I enjoy satellite operating. I
started with portable gear, mainly due to restrictions on antennas
and no safe place to set up my gear at the apartment I lived in for
a few years. I now live in a nice house, but it comes with antenna
restrictions. I'm making use of the back yard to work with my
gear (which you could see in the videos I posted last weekend),
and may be able to set up antennas on a tripod that can be put up
only when I'm using it. Until then, I continue to work with the same
portable gear I have been using for while - the same gear that I used
to work you last night from the DM23/DM24 grid boundary, when I
took a detour on my way home from Palm Springs and pulled off a
state highway in western Arizona.
I have over 11,000 satellite QSOs in my log from the past 6+ years.
Not a record, as there are others who have many more in the same
timeframe, but all but about 10 of the 11,000 were made with portable
gear from almost 200 different locations across the USA and 3 other
countries. When I looked at those QSOs a little while back, about
10% of those QSOs were in SSB or CW. I have gear that allows me
to work FM or SSB/CW satellites down to the horizon or the local
surroundings, and I'm not afraid to work signals that are not strong.
Is this mediocre? I think not. I already have the tools to do the job
and enjoy it. Eventually, I will make a QSO with what I will consider
the smallest station I can probably assemble for a non-FM satellite
QSO - a TH-F6A HT sending CW to FO-29, listening to the downlink
on the all-mode receiver in that HT.
As for preamps, there are situations where they may be needed. For
example, I talked with Bob KO6TZ at the hamfest in Palm Sptings
yesterday morning. He explained that he has a 125-foot coax run
from his antennas into his shack. Short of buying very low-loss coax
that is cost-prohibitive (if there is a type of coax for that length), he
uses preamps at his antennas. That's one example where preamps
are called for. That's a far cry from those using HTs with antennas
like the Arrow Yagi, Elk log periodic, or similar homebrew designs -
where coax runs are only a few feet at most, not 125 feet.
As for the rest of Frank's post:
> JOB WELL DONE WYATT!
> YOU AND ERIC (ON4HF) DESERVE A ROUND OF APPLAUSE!
Now this I will agree with 100%. Great job by Wyatt for working
ON4HF yesterday morning! Later in the day, I worked AC0RA
just after working K4FEG out in the desert on my way home,
adding a new grid to his satellite log. Wyatt was very busy
>> ... If mediocrity is your ultimate goal, use the minimalist approach ...
Was this just a poor choice of wording, or did you intentionally mean to insult hundreds of satellite operators who are enjoying the LEOs - as well as thousands of students and educators working the ISS annually?

I am using orbitron + Wispdde for auto doppler correction on my ICOM 821H. I noticed that the frequency correction at the Radio is not happening in 1Hz steps when on CW/SSB , the frequency correction is in 10 Hz steps but it shows in 1Hz in Wisp DDE. Any pointers to resolve the issue will be appreciated.
Wyatt Dirks AC0RA is very passionate about his satellite operations.
Having started with a home brew antenna, he has experimented with
several portable station configurations including LPDA’s, commercial
Arrows, and recently added a 13-element M2 beam.
Just today, January 28, he made a 6,941km contact with ON4HF using
AO-7 mode B. While this is several hundred kilometers below the
distance record for mode B contacts, it is important to note that
Wyatt performed this feat completely portable, without a set of
cross-polarized beams, without automated antenna tracking, and more
importantly – out in the cold Iowa weather.
He’s recently been making contacts with other stations in Europe.
This does not come easily in a portable setting from the mid-USA
states. Many folks who have been around for a long time, who have
“been there and done that,” may not see this as much of an
accomplishment. I assure you if we had satellites capable of greater
distance contacts, Wyatt would be on them pushing the limits of their
capabilities with minimal equipment.
Not only does Wyatt posses the right equipment, he demonstrates skill
and dedication, something uncommon in young men his age just shy of 20
years old. We should encourage operators of this caliber as they will
be our future engineers and friends in the space frontier.

We are again in need of a quality PCSAT command station in Hawaii.
This is for our Arctic Buoy experiment at the North pole! (off Barrow Alaska). The problem is that the ISS digipeater only gets gets 1.5 degree above the Horizon in Barrow. Probably won't work.
Fortunately, PCSAT-1 overflies the Arctic area 5 times a day listening on 145.825.
Unfortunately, the Buoy is set to digi via ARISS and will not digi via PCSAT-1 unless the PCSAT-1 alias is commanded to match the ISS alias of ARISS. This is a fundamental design of PCSAT, but when we set the ARISS digipeater alias, it only lasts until the next eclipse 30 minutes later, and so this command will have to be sent from Hawaii on EVERY pass where we want to check on the health of the Buoy. So we also need to train a Hawaii command station.
This will -not- be a daily task. Just occasionally when time permits to allow us to get back one health-packet from the Buoy every now and then.
If there is anyone fully conversant with conventional packet and Kantronics remote-logon and remote control of a KPC TNC, and is interested in this project, let us know.
