I notice when AO-7 is out there at 4000km I can notice the delay in cw from my monitor to the 8000km round trip to and from AO-7. Kind of shades of AO-40 (sobsob) when the delay was really noticable, and when we listened to ourselves (ssb) we had to turn down the rx volume a little as no to sound like a babbling fool.

If we could somehow harness those slightly faster than the speed of light neutrinos, discovered at CERN, and apply them to RF use, the delay could be reduced. ;)

I must try that!
On the "babbling fool" thing, try using DMR radios (Mototrbo, Hytera) with the 500ms processing delay: "Radio cheeeee uh one t- uhm uhubbuh..." tail off into incoherence. Of course since your mike is still open and the receiver is right beside it, you get this King Tubby delay feedback echo, Lee Scratch Perry thing going on.
no, but dilithium crystals should be able to handle that...those babies can do warp 9

LOL! That's too fast. That would mean the return broadcast would be that of our thoughts before we speak.
