Tell us what the path loss and and Power for a given S/N ratio is. Pick

a position and date for that position and tell us.

It doesn't work that way, Mike. I posed the challenge and it's up
to others to answer...such as yourself.

All the information is available to YOU. Won't take much searching
to find it.

No need for Keplerian tables or that other BS about "picking a position"
since all you need is the MAXIMUM distance for path loss.

Or, you can cheat and crib from NASA information. They've been
in the interplanetary communications business for over three decades.
Theoretical information is even older, and still accurate.

Tell us what the Doppler shift is over the length of a short QSO,
starting at the time of of start Assume a DX style QSO with a short
feedback message to insure actual reception on both ends, say a 35
second transmission. Then the same for the return message.

Illogical premise. Interplanetary QSOs have such long round-trip
times that your paradigm isn't worth 20 cents. Think about it.

Doppler shift isn't a big problem. RF power output IS. Think about
that...no ionosphere in between planets, nothing else like it.

At this time I don't know those details, but I'll be happy to check
them out once you've posted them. Add anything I have forgotten but may
need to know.

Sorry, Mike. It's up to YOU and the other latter-day saints of see-
double-yew to take the first shot. You are NOT the range officer
in this shooting gallery.

If you can't do it, well, you can't do it. No problem to me. :-)

Catalyst:

One that precipitates a process or event, especially without being
involved in or changed by the consequences.

Based on previous postings, you don't suspect that this fellow is a
catalyst, do you ? :-)

73, Leo
