I don't own a Alfa Spid, or any other rotator at the moment. I started
building a custom rotator and writing my own controller, using quadrature
encoders, pots, and 9DOF sensors to determine position. While researching
my options, I discovered that rotary encoders don't like long lengths of
wire. They work best with short runs of low capacitance wire. I2C is even
more picky. I had all kinds of issues when I was using cheap patch cables
for the i2c interface on the 9DOF board. I decided early on to locate the
controller in the rotator and keep the wire runs short, with final control
via ethernet.
I can't imagine that 50' wire runs are noise free. Is there any way to
locate the controller closer to the rotators? Perhaps interface to the
controller via ethernet? Ethernet can handle long runs quite well. I'm
surprised that so much of the ham equipment still requires serial ports.

Hello Jeff,
I have the same problem here. Changed baudrate and all kind of settings.
Nothing helps.
If you go to the "cat" menu in satpc32 you can change the cat speed x1,
x5 or x10.
Only at speed x1 i have no problem, but than the radio is changing its
frequency every second.
At cat speed x5 it's much better but than the radio changes modes when
turning the vfo.
My solution was simple, I connected another radio :-)
I use a ic-910 now and no problem anymore and i use the FT-847 as backup
radio.
73,
Eric.

Tom,
I run a raspberry pi with an RTL-SDR outside in a plastic box with a home
made coaxial collinear antenna. The range will be better once I mount it
higher than the current 5 feet. Sometimes I have to restart the wifi
bridge, but it's mostly hands off.

Walter Jackson Elementary School in
Decatur, Alabama had a successful ARISS radio contact
this past Friday morning. All 20 students received an answer to their
questions with full quieting reception for 90-95% of the pass.
Many thanks to the ARISS team for
making these contacts a reality in Amateur Radio and in the
development of the minds of young students growing to be our future
leaders.
Here is a link to a short article with
some video of the event by our local newspaper:

station/article_255a3b95-08bb-521f-b35e-ac8c9d795d86.html
We
are looking for some video from space during the Walter Jackson
Elementary School contact if there is anything with Timothy Peake. It would
also be nice to find pictures or video
on things he talked about like performing experiments, drawing blood,
floating around the ISS, lighting on Earth, the aurora viewed from
ISS, and the exterior view of the ISS with Earth in background. This
would be really meaningful in assembling a video for those students
and the school. If you know where any of these things can be found
or obtained we would like to hear from you.
We had members from several groups
participating in the event from AMSAT, the Decatur Amateur Radio
Club, the Huntsville Amateur Radio Club, and the Marshall Space
Flight Center Amateur Radio Club.
At the Huntsville ARC club meeting on
Friday night, one of the members played an 8 minute recording
captured on the downlink from the ISS using only an HT and a hand
held beam antenna. The signal quality was very good on this simple
setup demonstrating what can be accomplished. This has really turned
out to be a fantastic event to promote interest in Amateur Radio
Satellite Communications. Several hams throughout the state have made
inquiries about our equipment setup. What a great way to promote
interest in Amateur Radio and satellite communications.

Hello all,
I've been planning a trip out west for about 6 months now and have plans to
go through Nevada and take a whole week to operate from rare grids there. My
plans have been firming up and I am looking at being there during the first
half of May. Someone just told me that there is another ham, they did not
know who, that is ALSO planning a trip to Nevada in May. I would like to
find out who and where so that we can coordinate and not cause each other
any problems, not to mention any chaos and confusion on the birds. I welcome
someone else going... it will take pressure off of me as some of those grids
are very rare and I would like a little time to sight see. It would just be
nice if we could go at different times so that everyone has maximum chance
to work those grids and the two of us not duplicate efforts. - Not to
mention it would be nice if they went before or after me, so I'd get a
chance to work them and vice versa. =^D
If anyone can foreward me any information, i would certainly appreciate it!
Also, I will be posting info about my trip so a special QRZ page as well as
a special twitter account.

I have been experiencing an arcing noise all over the vhf sat sub band and
the 17m band for months.Finally decided to look for it.As soon as I walked
out the door with H.T. in hand, it disappeared. Searching the house found
it to be both Verizon phone chargers.Unplugged them,problem gone on vhf
and 17m.
They must be mini switchers.
