[NLRS] Rule 1.12 discussion

Another way to think about it: Do we require everyone to purchase a
GPS-locked 10MHz source and use it for their transverters and
tranceivers?  They are readily available and their use would limit
wasting valuable spectrum space. We don't because a) they are
expensive and b) there is a lot of spectrum space in the microwave
bands.

Why should we require everyone to buy a laser and/or an interference
filter? It may be that, because we have sensory neurons that can
respond to these wavelengths of E-M, they must be "less exotic".
Therefore, to put them on the same scale of difficulty as other E-M
bands, we must make the rules more stringent. What do you think?
