The biggest problems with the roving radio comm centers is desense.
With all the antennas ganged up on the roof of such a small area they

I have to disagree somewhat. Having gone through an exercise
in determining "closeness" of same-band aircraft radios on the
same aircraft (civil aviation band at 118-137 MHz) running 10 to
20 W max AM, only five wavelengths separation was fine.
That was back at a time (early 1970s) when high-third-order
IM specs hardly existed.

In a relatively local area, most such emergency comms will
be, generally LOS, and not "working DX." There's no point
in everyone running transmitters full-out in power for relatively
short distances. Yes, I'm familiar with Oregon topography
but NVIS techniques can also get out of the trees and the
deep low spots. If there's a Power Output control on the
rigs in use, it ought to be used to drop the RF output and
minimize desensing of nearby radios.

I'm just tossing in some things to consider in real-world
conditions. It isn't anything against what anyone is doing.
