Subject: [amsat-bb] Options for safer & permanent roof access?
Hello everyone.
Most of the time, when you're looking for how-to ideas, searching online
will result in lots of options.? This time, I'm not having much luck - with
the exeption of expensive commercial solutions.
What I would LIKE to see are some ideas on how I can give myself better
(permanent) access to the roof that is more stable than an extension
ladder.? I only need to get up about 4 meters to a simple "A" roof, but
with every passing year that transition from the top of the ladder to the
sloped roof becomes more dangerous.
Has anyone built exterior stairs or utilized a fixed ladder to the roof
perhaps with some extended hand rails to make getting on & off the roof
less hazardous?
Alternatively, I'm certainly open to a purchased or second-hand solution if
the cost is reasonable.
Pictures would be great if anyone would like to share a URL or two.
With the number of antennas that have been put on the roof by Amateur Radio
operators over the decades, I have to think that someone out there besides
me got tired of using a plain old ladder at some point.
Thanks!
-Scott,? K4KDR

I have a side mounted Rohn 25 that is ideal for me to get on the roof.
WX station and couple of antennas on up the tower works very well.

Thanks very much for the replies so far!
Oh yes, very much in the US. Just didn't want people from other parts of

I'll look forward to possibly even more ideas in the coming days as people
catch up with their email.

Hello
I am making a turnstile antenna and interested to seek ideas on how the
support the upper two dipoles
I see some people have sort of supporting material that fits inside the
upper dipoles
I am hoping to keep all the rf connections inside the pvc pipe which forms
the vertical supporting structure of the antenna
No one makes commercial turnstiles ?

Return of Experimenter's Wednesday to AO-85
With the recent popularity of Slow Scan Television (SSTV) from the
ISS, AMSAT Operations is bringing back Experimenter?s Wednesday to AO-
85.
On a trial basis, we invite users to exchange pictures using Robot
36 SSTV mode via the FM repeater on AO-85 during UTC Wednesdays.
Please identify prior to beginning transmissions, and only send when
the uplink is clear.
Stations are requested to only uplink if they have a reasonable
expectation of maintaining a full-quieting signal for the duration of
the image transmission.
Smaller stations are encouraged to focus on receiving the images.
Please don?t send questionable or provocative images. If in doubt,
pick another one.
Expect all ages to be participating.
Feedback is encouraged, and comments may be directed via email to me
at ko4ma at amsat dot org.

ARISS contact planned for YOTA, England
An International Space Station ARISS contact has been planned for
astronaut Paolo Nespoli IZ0JPA and the Youngsters on the Air (YOTA)
event, which takes place in UK.
The ARISS contact is scheduled Tuesday August 8, 2017 at
approximately 18.38 UTC.
This will be a direct radio contact, operated by GB4YOTA.
Downlink signals will be audible in parts of Europe on 145.800 MHz
narrowband FM. Moreover, Paolo Nespoli IZ0JPA will operate the
HamVideo transmitter.
The Goonhilly receiver will be activated sometime Friday (4th
August) and will remain active over the weekend and continue to track
the ISS until Wednesday morning, 9th August. Goonhilly, will be one
of several European HamTV reception ground stations contributing to
the reception of the HamTV signal for the contact itself.
Two web streams will be available:
1. The normal ARISS/BATC website will be available at
https://ariss.batc.tv/hamtv ; This shows only the HamTV video
downlink as an output from the merger facility, with an indication of
which registered HamTV stations are providing signal input to the
merger.
2. The ARISS Operations UK Team will be web streaming from the YOTA
event itself at https://ariss.batc.tv/ ; This web stream includes
introductions and presentations from the RSGB and the YOTA
participants before the actual contact itself according to the
timetable of the event below.
The timetable of the event is as follows. ALL times are UTC times:
17:30 - All participants and guests to be present at the location.
The event web stream (https://ariss.batc.tv/) will start at
approximately this time to capture some of the build-up.
17:40 - Formal start of the RSGB/YOTA introductions and
presentations.
18:20 - ARISS Operations in the UK take over the event, give the
background to what is happening, how it is organised and how all the
different elements of the contact are managed.
18:38 - Scheduled time for start of contact with Nespoli operating
as NA1SS. The YOTA participants will be using the GB4YOTA callsign.
18:50 - Approximate end of contact with Nespoli. After closing the
contact, the operator will invite RSGB/YOTA to formally close down
the ARISS event.

ARRL PR Poster Features Amateur Radio in Space
The ARRL offers a series of six posters that promote Amateur
Radio to the general public. These were originally designed
by ARRL for the 2017 National Scouting Jamboree, but may be
used for any outreach effort. Each poster is 11" x 17".
One of the posters features amateur radio in space.
The six posters are based around the theme, "Ham Radio Is..."
Those themes are:
+ Adventure (Portable operating of all kinds)
+ Discovery (Making/Building/DIY)
+ Friendship (Community and Mentoring)
+ Out Of This World (space communications/satellites)
+ Ready (Publc Service)
+ The Game (Contesting and Awards)
A link to ARRL's "What Is Ham Radio" page is provided as both
a URL and a QR code on each poster.
The posters are available for free download in PDF format.
http://www.arrl.org/pr-posters
We suggest printing on high-gloss paper and framing them
for maximum effect.

AMSAT Phase 4 Groundstation at DEFCON
Amateur Radio and AMSAT were prominently featured this year at
DEFCON Hacking Conference. In addition to the license exam session
run by one of the many local DEFCON Groups, there were amateur radio
demonstrations of software defined radio, Phase 4 Ground, and GNU
Radio flowgraphs at WiFi Village, one of the many subject-specific
subcategories at DEFCON. The amateur satellite service was of great
interest!
At an estimated 30,000 attendees, outreach was highly successful.
Participants were diverse, technical, curious, and came ready with
the questions! A very high fraction were already licensed or
interested in getting their license.
Amateur radio was also part of the WiFi Village Capture the Flag
competition. Word on the street is that next year we expect to see a
lot more ham content in this exciting signal intelligence competition.
AMSAT Phase 4 Ground will next present at the GNU Radio Conference
in September, in San Diego, CA.

AMSATSA/SARL Workshop To Focus On Taking SDR To A New Level
The AMSAT SA/SARL workshop, to be held on Saturday 19 August at the
SARL National Amateur Radio Centre at Radiokop Roodepoort, will focus
on how to get more out of Software Defined Radio, and will take
participants to another level in Amateur Radio activity.
The workshop will be presented in two sessions. Session one will
deal with the VHF SDR dongle and how to have more fun, such as
listening to satellites, receiving weather satellites pictures, and
astronomy projects. The second session will discuss a HF Dongle and
the SARL HF Noise floor monitoring project, with details and a
demonstration of how to automate this and how to build an autonomous
system using a raspberry Pi.
For more details and to check your registration status, point your

+ Satellite has deployable VHF crossed Yagi antenna
Radio amateurs Sean Hum VA3SHV and Jeff Nicholls VA3NGJ worked on
the design for a deployable VHF crossed Yagi antenna on the recently
launched NORsat-2
The very high frequency (VHF) antenna was designed to unfold from
the CubeSat after receiving a command from the Norwegian Space
Center to deploy once in orbit.
?This antenna is a completely new type of deployable antenna ? it
unfolds to be more than three times as large as the satellite that
took it into orbit,? says Hum.
?This is the first time that a deployable antenna of this type has
been contemplated and successfully used as a main mission antenna
for a CubeSat.?
On July 20, cameras on board the CubeSat confirmed the successful
deployment of the antenna.

Hi Andrew, recently VK5QI purchased a 70cm turnstile from fleabay.
He modified it slightly and it is producing some very good results.
