I've worked a number of cw stations on fo-29, both cross-mode (when I
don't have a key) and on cw myself. Less than 5w always... and all but
one time was with 2xFT-817 hanging around my neck with a palm pico stuck
on one of them, and a handheld arrow antenna while tuning manually. So I
would say if you are having trouble hearing other cw ops, it might be
worth checking over your station (esp the rx signal path..). If satpc
isn't keeping up with doppler, maybe check your tuning steps too..

Hi Dave
> I am rebuilding my antenna stack and while I have used RG-214 as the coax
pairs from the ants around the rotator to the pol switches in the past, I
wonder if anyone has any other suggestions for coax.
I had the main runs using westflex (I still have a drum I don't want) but
used a more flexible cable around the rotator. H100 would be good if you
have some otherwise the best (thick) cable you have will do.

International Space Station Astronauts are Calling CQ Students (corrected)
?????????????? ARISS-US program education proposal deadline is April 30, 2018
?
March 15, 2018:? The Amateur Radio on the International Space Station
(ARISS) program is seeking proposals from US schools, museums, science
centers and community youth organizations (working individually or together)
to host radio contacts with an orbiting crew member aboard the International
Space Station (ISS) between January 1 and June 30, 2019.
?
Each year, ARISS provides tens of thousands of students with opportunities
to learn about space technologies and communications through the exploration
of Amateur Radio.? The program provides learning opportunities by connecting
students to astronauts aboard the International Space Station (ISS) through
a partnership between NASA, the Radio Amateur Satellite Corporation, the
American Radio Relay League, and other Amateur Radio organizations and
worldwide space agencies. The program?s goal is to inspire students to
pursue interests and careers in science, technology, engineering and
mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how
Amateur Radio is the most unique hobby/service there is.?
?
Educators overwhelmingly report that student participation in the ARISS
program stimulates interest in STEM subjects and in STEM careers. One
educator wrote, ?It exceeded our expectations--it created a great interest
in both amateur radio and in space exploration. Our kids are completely
inspired!? Ninety-two percent of educators who have participated in the
program have indicated that ARISS provided ideas for encouraging student
exploration and participation. An educator even joined the ham ranks,
saying, ?This chance for our school?s ARISS contact helped me see the great
value of the ham world.? I just passed my Technician License this weekend
and have already signed up to take a General class.?? ?
ARISS is looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed, exciting
education plan. Students can learn about satellite communications, wireless
technology, science research conducted on the ISS, radio science, and any
related STEM subject. Students learn to use Amateur Radio to talk directly
to an astronaut and ask their STEM-related questions. ARISS will help
educational organizations locate Amateur Radio groups who can assist with
equipment for this once-in-a-lifetime opportunity for students.
The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars
for guidance and getting questions answers will be offered March 29, 2018,
at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is
necessary. To sign up, go to
https://ariss-proposal-webinar-spring-2018.eventbrite.com

form, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html

Content-Type: text/plain; charset="UTF-8"
Thanks to everyone who responded to my post. Here is a summary of the
various option, plus description of my ultimate choice.
There were several good options:
Paul W2HRO suggested Sector Microwave SM7 switches. Uses N-Type
connectors, will handle 1200 watts or more on 2 meters: A Cadillac option
with $225 price tag.
Eduardo PY2RN sent a link to a PDF showing different options using manual
coax switches and/or multiple Diplexers.
Burt FG8OJ sent an eBay link to a $10 NAIS ARD62024 transfer switch - this
was the option I decided to pursue.
The ARD62024M01 has four SMA Female jacks, handles 120 watts at 3 GHz, has
.2 dB insertion loss at 1 GHz, and has gold plated contacts. It is about
1.3 inches by 1.3 inches by 1.8 inches, or 32mm x 32mm x 39 mm (46mm
including SMA jacks).
The 24 at the end of the part number means it is a 24 volt relay. This is
a latching switch, so momentary application of voltage to one wire switches
and latches it to Position 1, momentarily applying voltage to another wire
switches and latches it to Position 2,
In Position 1: J1 <=> J2 and J3 <=> J4
In Position 2: J1 <=> J3 and J2 <=> J4.
So I put the 2 meter antenna on J1, 70 cm antenna on J4,
the receiver on J2 and transmitter on J3.
So in Position-1 the 2 meter antenna is on the Receiver and 70 cm antenna
is on the Transmitter.
In Position-2, the 2 meter antenna is on the Transmitter and 70 cm antenna
is on the Receiver.
Add a pair of momentary-on push button switches: one energizes the latching
relays into Position 1 (u/V), the other energizes the latching relays into
Position 2 (V/u).
I purchased 3 foot cables SMA Male on one end of all 4 cables, with the
other end of one a PL259 for my Yaesu FT-897 (used for xmit), two with
SO-239s for the 70 cm and 2 meter antennas, one with SMA-Male for the
Funcube Dongle Pro Plus receiver.
It works great - I love the latching relay concept. That way a failure of
the power supply won't cause the antenna to flip from U/V to V/U, or vice
versa.
Total cost was about $85, $17 for each of the four cables and $10 for the
coaxial switch plus shipping.

Thanks again to all for the great ideas!

Amtrak 1 way ticket to Cincinatti from Wash DC is only $75 (but only 2
seats left. THen it goes up to $95 or so. Or over $400 for a sleeper
Too bad Hamvention is in Dayton and not in Cincinattti, and I cant get the
window open for my Arrow either.
