[Elecraft] K3/0 all in one box?

[Edouard Lafargue]

(First post on this reflector!)

   Well, an ethernet link can go up to 10Gbit on modern ethernet links, so
sending an 8MHz signal with a decent sampling rate and resolution is
definitely possible, but only on a local network... As an extreme, the
Arecibo radiotelescope uses RF over fiber all over the place, given its
dimensions, and they are more often than not in the GHz range!

    On the other hand, if you look at tools like websdr (
websdr.ewi.utwente.nl:8901), or the Open Source project ShinySDR (
https://github.com/kpreid/shinysdr) they simply do the FFT in the backend,
and just stream the image of the waterfall which for all practical purposes
works quite well - at least that would address the "remote P3/PX3" part to
a large extent. You would be able to visualize a very wide waterfall
remotely using a very reasonable bandwidth. So yes, a remote panadapter is
quite feasible...

My 2 cents, and hoping this brings value to the conversation :) (2 cents at
least)
