Contests working Earth-Mars contacts should be interesting, when
you remember that speed'o light means that radio signals take
about 5 to 15 minutes one way to make the trip...

If my math is right, the one-way transmission time works out to between 188
seconds at closest approach to 688 seconds maximum.

Hmmmm - interesting math for an MSEE..... and quite incorrect indeed.
Good amateur-level research skills, though.

His skills rusty. Works for EPA. Solve global warming.

Nah - I'm pretty sure he claims to have had a successful career in
electrical engineering - a field where, I suppose, being off by over
100% in a calculation would be completely acceptable (so THAT'S what
fuses are for!). 8*p

That can all be blamed on the pentium floating point zero.

That, and being employed full time in amateur radio, and currrently
working on his WAU (Worked All Usenet).

One day he woke up and found out he had a career in amateur radio.

A bit short that. According to my Almanac ("World Almanac and
Book of Facts 2001" published by World Almanac Books, p. 587),
the minimum to maximum distances of Earth to Mars are 34 to
249 Million miles. At 186,000 Miles per second, the ONE-WAY
time works out to be 183 to 1339 seconds (3.05 to 22.3 minutes).

Now them's the right numbers! The following website confirms these
distances, after conversion from km to miles:

Ooops. Now you've done it. Never, Ever back-up anything Len has posted.

Here comes Hiram's Hammer! Duck!

A single two-way contact, one transmission at each end, would
take 6 to 44 minutes to complete, depending on the planetary
positions. The limiting factor on "rag chews" would be limited by
rotation of both planets. :-)

...and those periods when that pesky moon of ours is in the path

But it's made of cheese. Only very slight attenuation at HF.

Of course, Rev. Jim, you WILL call MY calculations "incorrect"
or "wrong" or something like that, won't you? :-)

Careful - you're contradicting an expert here - ain't never been wrong
yet! 8*p

Hi, hi!

It's true! Just ask him!

Jim won't say. Just ask him! Hi, hi.
