[WIham] 70CM Up For Auction?

Scott,

Actually the 400 MHz board isn't Part 15, but that isn't important.
We have historically re-purposed Part 90 commercial radios as well as
Part 15.  (remember the 900 Mhz rabbit video sender, and 2.4 GHz
wavecom jr video sender that we have used for ATV?)

You ID by sending your callsign in the data.  Historically most have
either changed their MAC address to their callsign or have embedded
it in a ping packet, etc.

Technically OFDM isn't considered spread spectrum.  However if any
ever runs more that 10 watt I think they need to read up on that old
phenomenon of hidden transmitter syndrome.

The point is the current band-plan that caves out the lower portion of
the band for ATV isn't bringing any real traffic/ use either.  You
nailed it on the head, the magic word is "modernized"

With a decent data rate you can link repeaters, with this instead of
relying on the internet.   Etc.

"Emergencies don't happen everyday."

I agree, and will never understand the huge emphasis on ARES, but that
is straying from the topic at hand.
