Hi Reid,
I understand the desire for minimal use of connectors, but the coupling
between the rigid cable coming from the shack to the rotor, and the flex
cable going to the antenna, is a good place to put a nice little
preamp. Think of it as a barrel connector with attitude. Yes, putting
it at the antenna feed point is better, but unless you're working EME,
the practical difference is pretty small.
Your luck with 9913 and water ingress is significantly better than mine
ever was. I had one 60' run that kept getting worse over time. It got
so bad that I drilled a hole in the lower end connector so I could suck
out the water until I could find some hardline to replace it. Never
used the stuff ever again.

Hi All,
Just to report that FUNcube-1 is now in amateur mode for the rest of the
weekend. Transponder and low power tlm as usual.
In view of the late mode change this morning we will leave her in this mode
until Monday morning

I had better luck after protecting the connectors with pill bottles.
This worked for a while but the UV would wipe out the bottles in a short
period of time. After that I used short pieces of SCH 40 PVC with
modified end caps for the cable and didn't bother to glue. This worked
much better, plus allowed me access to the connectors when needed. I
also did this to the rotor connectors.

There was no shortage of activity on the XW-2A,C, and F transponders
this morning. On the passes around 1300 UTC, stations were heard and
worked from the east to west coasts of the USA and Canada.
These are some of the easiest transponders to hear. They are very
workable with the most modest of antennas and low power.

Please join us in listening to the ISS contact with participants at the
Kiilinik High School, Cambridge Bay, Nunavut, Canada on Wednesday April 6. AOS
is anticipated at 18:02 UTC
The duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be a telebridge between NA1SS and VK5KHZ in Australia. The
contact is expected to be conducted in English.
Audio from this contact will be fed into the:
EchoLink *AMSAT* (101377)
IRLP Node 9010 Discovery Reflector
Streaming Audio at: https://sites.google.com/site/arissaudio/
Audio on Echolink & web stream is generally transmitted around 20 minutes
prior to the contact taking place so that you can hear some of the
preparation that occurs. IRLP will begin just prior to the ground station
call to the ISS.
** Contact times are approximate. If the ISS executes a reboost or other
manoeuvre, the AOS (Acquisition Of Signal) time may alter by a few minutes

What he said. In other words, I concur. I have had a whole bunch of VHF/UHF
antennas fed witl plain LMR400 for years, and with a bit of a coil around
the mast, it all worked fine.

I beg to differ. As long as there is a reasonably-sized, loose loop around
the mast, LMR400 will last for years to decades, not days. Mine did, for 20
years, in Minnesota weather (temps ranging from -30F to +100F). Planning to
do it again when the tower goes up here in Texas.

I had a dualband 2M/70cm vertical that was fed with 9913 from antenna to
the house, and whtn properly prepared N connectors on both ends, it never
leaked water. Well, at least not until I tried to drill another hole into
the house next to the first one, and the drill bit went in at an angle and
drilled right into the run of 9913. Ouch. I replaced that run with LMR400
and never looked back. It survived for over 10 years, but of course with no
motion involved there. ;^)

Irvine Students Are On a Mission to Launch a Satellite
The los Angeles Times reports that over a hundred students from five
Irvine high schools and another dozen from a local middle school have
begun a year long collaboration to engineer, launch and place an
operational nanosatellite in orbit.
Teachers from Beckman, Irvine, Northwood and Woodbridge high schools
developed curriculum for teams of 20 to 25 students from each school
to handle the CubeSat mission.
Students from Irvine's new Portola High School will be brought into
the program when the campus opens in the fall. Students from Rancho
San Joaquin Middle School are involved in the project as a STEM
feeder program. Organizers of the Irving project are in discussions
with a Russian company and have targeted a March 2017 launch date.
Irving Public Schools Foundation have granted $150,000 in seed money
to launch the project.
The schools are planning for three years of missions with a goal of
rolling over in perpetuity depending on funding and future support.
The project is the brain child of Brent Freeze and Kain Sosa,
neighbors in Irvine's Quail Hill subdivision, who have children in
the school district. Their goal is to support education that requires
specialized science backgrounds and recognize that developing talent
could start with STEM programs in local high schools.
