When the Earth image is about 4 across (8,000km), and the satellites are
one pixel across (say .001) then each dot is actually to scale a
spacecraft that is 8km wide. Which is about 8000 times bigger in diameter
than a real spacecraft.
So what you are seeing is what space would look like if
Good morning,
I was curious about the rules for the the OSCAR Satellite Communications
Achievement Award, the OSCAR Sexagesimal Award, and the OSCAR Century Award.
The rules from KK5DO's website state that A contact is defined as one with
a station in another state, DXCC country or Canadian
I don't know much about colliding dots but ..
The volume of space from surface of earth up to about 200 km is roughly 1 to
the 20th (cubic meters).
The volume of a spherical spacecraft with a diameter of 5 meters (slightly
larger than a cubesat) is about 500 (cubic meters).
Assuming 10,000 of

If the FCC and ARRL would recognize the District of Columbia with its
own prefix as the RAC has done with their provencies and territories
then we should. However, until they do, it is included as a contact for
Maryland.
Here is the list from RAC that they use for their contests.

Bruce,
That an illogical argument. Only three states have their own prefixes:
Alaska, Hawaii, and California.
It also ignores the fact that the District of Columbia is not part of
Maryland. Incidentally, DC is the only top-level subdivision of the United
States or Canada that does not count as a
I took over processing the awards for AMSAT over 10 years ago and have
processed it the same way the previous awards managers had done.
You are absolutely correct that DC does not count for this award because
in creating our award, we used the ARRL worked all states award, the RAC
worked all
The Virgin Islands, Puerto Rico, Guam, etc. all count as separate entities
for these awards as DXCC entities.
I find it ironic that an organization that is incorporated in the District
of Columbia and had it's first headquarters in the District of Columbia
would not recognize that the District of
I understand that the AmSat BB is 99% serious business. I think it's time to
lighten the mood a bit.
I'm going to (try to) fund a new project. I want to place a satellite with a
full-sized 160m beam into orbit. I want this thing to be highly polished or
plated in Chrome. (It will put the

How's that for a dumb idea?
Wonderful, only drawback is that 160m isn't allocated to the Amateur Satellite
Service ;-)
Of course that's true of all the LF

Reminds me of the two antennas who met up on the roof. They fell in
love and got married. The ceremony wasn't much but the reception was
fantastic ...

Hi Trevor,
Yes we are discussing the removal of the downlink only restriction on 29MHz
and the proposal to permit satellite linear transponder downlinks to operate
at the bottom of the 144MHz band (just 22.5kHz though)
The meeting is still in session at this time

Which leads to a surprising problem. Suppose a cubesat at the end of
