Or perhaps grabbed the distance data off the wrong website?
Oh, my! Had anyone else come up with those numbers you
would have sent many a multi-screen message accosting
them of error-prone perfidy! :-)
I can see the reply now: "Wrong again, ..xxx.......", followed by the
usual Jim-style rub-the-nose-in-it verbiage.
Here's a more exact calculation:
Per NASA website, the Earth's orbit varies from 149.5 to 149.7 million
kilometres and Mars' orbit varies from 204.52 to 246.28 million
kilometres.
The closest the two planets approach is 204.52 - 149.7 = 54.82 million
kilometres
The farthest apart they get is 246.28 + 149.7 = 395.98 million
kilometres
Using 0.3 million km/sec (that's 300,000,000 metres/sec) as the speed
of light, we get:
54.82 / 0.3 = 183 sec (3 minutes 3 seconds)
395.98 / 0.3 = 1320 sec (22 minutes 0 seconds)
give or take......
What, no EXACTNESS? Speed of light isn't EXACTLY
that nice round figure. Tsk, tsk.
Precision is for others.
But you can count on contest ops to figure a way to make that work. Use the
transmission time as a 'buffer' of sorts. Not a problem.
Ingenious use of the delay interval would permit pretty good contest
rates. Of course the ability to work duplex would be a plus.
I am non-plussed. With a 44 minute round-trip time you wouldn't
need any sort of T/R switch, just solder some lands on a PCB to
do the same job to go from Rx to Tx and back again. :-)
For rag chewing, contacts between fixed nonpolar stations on each
planet up to about 12 hours long are possible if the locations are
just right at both ends.
You could WEAVE the rag material, cut it to shape, sew it up
in the time of those contacts... :-
No problem, though, for someone who takes 48 hours to reply to this
little Usenet-based QSO - and fails to reply in context of the thread
at that.
"I just noticed that I was incorrect - all by myself!" Duh.
SO2R is just the beginning.
Of course the reason no one - professional or amateur - has been
awarded the Elser-Mathes Cup is because it requires operators at both
ends of the QSO. Human space programs won't be in a position to do
that for decades yet.
Ah! One of the remarkable OBVIOUS statements! :-)
And a brilliant one at that.....you need someone on the other end of a
QSO? Sunnavagun!
I hearby nominate you for three or four votes in the Department of
Redundancy Department.
But not the Department of Mathematics.
Okay, now what is the PATH LOSS and what kind of Tx power is
needed at each end for a given S:N ratio?
Can you get by on amateur radio power levels? Without violating
any of the regulations?
