Hi,
The re-boost scheduled for tomorrow
has been cancelled. Apparently the
last re-boost in January caused
excessive shaking to the station and
flight controllers want to understand
why before they do another burn.

I did wonder myself, the story doesn't actually say which part of the system
was "home-built".
Back in the 1920's Radio Amateurs build their own components (resistors etc),
these days things have moved on and we develop systems that can embody
complete transceivers as a component-part.

A YouTube video which shows the satellite, it's construction and launch
can be seen here.

Obviously the satellite has no solar cells and may only operate from
batteries..

Cell phones need about -95 dBm received to work at all (and really at
-95 dBm about all you get is network beaconing, with no ability to
actually place a call). Typical cell transmit powers rarely go past
one watt, and I think the cell base stations rarely go much over ten
watts (per channel). I think you'll find that there's too much path
loss for that to work to even LEO, notwithstanding the fact that cell
tower antennas typically have radiation patterns that send virtually
all the signal into terrain, that being where the cell phones are.

Some systems (GSM being the main example) have a distance limitation,
of how far you can go from the base station, without losing sync due
to propagation delay. Suffice to say this is well short of any LEO,
even the ISS.

Alinco DJ-G7 - This is the radio that should be announced at Dayton
this year. Production of the U.S. version expected to start in June.
Neither price nor specs for the US version are currently available.
It's on Alinco's Japanese Web site ...

George E. Caswell, 63, of Scarborough, ME died peacefully at the Maine
Veterans Home on February 3rd after a lengthy illness. He was born and
raised in Waltham, MA, the only child of Vera and Leslie B. Caswell. He
was married in Newton, MA on Jan 3, 1970 to Caroline Parmenter of
Palermo, Maine. In 1978 they moved to Scarborough, ME where they raised
their two children, Christine and George Jr.
George was an avid ham radio operator from the age of 13 when he
received his first call sign, K1MON. In later years, after relocating to
Maine, he changed his call sign to W1ME. George was particularly
interested in amateur satellite operation and contacts with astronauts
aboard Mir and the ISS. In Feb 2005, he set up his radio station at the
Rockland, ME high school as part of a PenBay radio club activity and
contacted the International Space Station, allowing high school students
to communicate with the astronauts aboard. It was one of the highlights
of his amateur radio involvement.
George was educated in Waltham, MA schools and attended Westbrook
College for two years. He served in the U.S. Army from 1965-1968 with 27
months being served in Viet Nam. He was employed by Verizon, originally
New England Telephone, for 31 years as a central office technician.
George was also a private pilot for many years and a former member of
the Baldeagles Flying Club in Portland.
George is survived by his wife of 39 years, Caroline P. Caswell;
daughter Christine and her husband Moises Nu?ez, of Somerville, MA: son
George and his wife Laura Johnston, of Reading, MA; mother-in-law Elsie
Adams of Palermo, ME; a special niece, Sara Robinson, her husband Mike,
and daughters Makayla and Jayna; brothers-in-law Jack Adams of
Fairfield, ME and Ron Adams of Houston, TX and their families: and
several nieces and nephews.
Family, friends, and neighbors are welcome to an open house at the
Caswells? home at 16 Westwood Avenue in Scarborough on Saturday February
7 from 2-5pm to share memories and condolences.
The family will have a burial service in the spring at the Maine
Veterans Cemetery in Augusta.
Donations in George's Memory may be made to:

Orbit 30 passed pretty much right overhead at my QTH at about 1710. The
signal was strong enough to pick up inside with my HT's rubber duck, but
no modulation. Wonder if that's it on the way out?

Hello All,
I know this was discussed before, but I want to bring it up again.
Does anybody have a Linksys wireless router/4-port hub that does NOT
make ugly noises around 145.870 MHz (and the satellite portion of 2M
in general)?
I don't want a D-Link (bad previous experience), and I prefer Linksys;
but I would consider some other brand.
Thanks in advance for the feedback!

I recall doing a broadcast remote where I was engineering the remote from a
single engine aircraft. At about 5000 feet or so, I lost all cellphone
functionality because I was getting into too many cell sites at the same time
and the system locked me out (thats the best explanation I could come up
with). Even if there was enough signal from that distance, I doubt it would
work for that reason.
