And you can receive it just
fine with a dipole.

Thanks Roy.

It now makes perfect sense to me that since CP can be generated with
two linear antennas (crossed dipoles, phased appropriately), it must
be true that one could make linear using two CP antennas - just as you
reminded us.

Still - I have a nagging feeling that, taking advantage of the -3dB
separation between CP and linear, there must be at least a small (3dB
SNR) Shannon window in there that might be used to squeeze through
some extra data. Likely not (yet) cost effective even it it does
exist.

I appreciate all the responses.

Now - what shall I do with the $10,000 that I didn't spend on a patent
?
