This could work if he can get his receiver to perform like the flagship
rigs of the competition, including bettering the VI+. See 505DSP in:
http://www.elecraft.com/K2_perf.htm, especially Ip2 and BDR. I've not
used a 505DSP in a contest, but with those numbers, I doubt I would
happily for long.
More importantly, the VI+ needs the low-tech improvements I mentioned
earlier, especially dual-receive, preferably with a subreceiver, getting
rid of the birdies, and VBT (or multiple digital filters with kind skirts
if you go high-tech) rather than PBT. Frankly, I hope they keep VHF out
of it, just more compromises to make and noises to introduce.
I want a radio to use on the air, not play with on my computer; yes, with
an interface to my contesting and logging programs and maybe a flash
memory to update firmware. I don't even care if they put digital mode
software into the Orion itself and pass the data out the RS-432 or
firewire port, but I sure wish ops who use it would listen to see if the
frequency is clear before they transmit.
For some fun, let's guess price - 3 KBux?
