Is there any doubt here? Are you doubting that I exist or that I am a doctor?
Why the "apparently"? My Ph.D. is from Cornell University. 1985. Last time I
looked, I exist. A little too much flesh--but undeniably extant.

I am not associated with SL--yet. On another post I said I will apply this
weekend. I did indeed say, three weeks ago, that I would join. It's on my list
of things to do.

I do indeed state that the SCIENCE of telecommunications obviates the option
of a SINGLE MONOCHROMATIC line transmission over anything but the closest of
cosmic distances (greater than about 200 ly).( The galaxy is 100,000 ly
across.) But on the other hand, I am not advocating broadband. Rather a
series of NARROWBAND transmissions spread out in frequency over HUNREDS OR
THOUSANDS OF MEGAHERTZ. This is because multipath effects make the single line
mode unacceptable. If someone else has an efficient solution to
multipath--that's easily detectable--then clue us in!

IF you listened to the Laura Lee show, you will see that this attempt to
correlate an INTERFERENCE transmission with another --presumably--INTERFERENCE
transmission has no basis. Ray Norris's work is corroborative wrt the HOAX;
Since neither GU0NHD or JA1TR nor Paul Dore had anything to do with the data
bogusly ascribed to them one can hardly use fraud to shore- up an alleged
detection. Futhermore, the data was fabricated and did not portray what anon
said was there...

If you are attempting to say that Ray Norris' work fits into the
polychromatic scheme for multifrequency, narrowband transmission, the answer
is NO. Multipath effects correlated over decades of MHz. You have to spread
out the separations over a huge range, then use a 'dipper' mode to find them.
