Jim,
With the way the DEFCON contest seems to be run ...
You can set up something to use 12 foot dishes.
Run under part 97
use a BelAir 100 (27.5 dBm and good receiver sensitivity)
oh sure.
get them to sponsor you
unlikely, at least while I still know the VP of marketing. :-)
and modify their phy and mac slightly to accomodate DX contacts
and... ya lost me.
1) you're not going to modify their PHY, its just an Intersil part.
<--- several million dollars to develop a new part
2) even ***BELAIR*** can't modify the MAC. They paid Nesus to do
so, and while I won't reveal the figure, it was *expensive*.
might as well drop a DSP and a couple FPGAs on a board and develop
your OWN radio.
(wink-wink)
nudge nudge
for example, increase the chipping rate and decrease the raw data rate
so that you get much more processing gain...
uh... use one of the modern Atheros chipsets that does this with OFDM
(course, then you can't run Part 97, but apparently rules
are made to be broken.)
Maybe even get the first EME contact on Wi-Fi
unlikely
I really think that DEFCON needs to revisit their contest rules
so do I.
