[TowerTalk] Minn State courts and towers

[n4zkf]

Correct, but the current lighting systems are not capable of flashing the
L810 (markers). Only the strobes. So they are running to the design table
to come up with a fix. I guess everyone will be going to LED systems as
it's the only one that will be capable of doing it. They are even going to
allow less markers in the end also and up the height. While all this is
mostly commercial and won't effect hams, the 312's and 324 systems will be
for sale used everywhere for just about free..
