Hi all!
I agree. There should be more incentive to use the higher bands than there is. If you happen to be an ARRL member - or even if you're not - the person to make your opinions known to is the guy who can do something about it, your local friendly ARRL director (name and address on page 15 of any recent issue of QST).
I find the "coherent" requirement particularly amusing as I suspect that beam from a typical semiconductor or HeNe laser isn't even coherent a kilometer away. It's still exceptionally well collimated at that distance, but not coherent! How is a well collimated LED (which is also very monochromatic) all that different?

For conest purposes, each laser Q must have a separate transmitter/receiver for each laser contact made (to prevent manufactured QSO's).

But, the real killer is that a laser contact counts no more than any other microwave contact-so there is absolutely no incentive for a rover to carry laser gear and to devote the additional time needed to make a laser Q.

I think that a minimum distance for a laser contact might be 5 miles-this would ease the fear among non-laser people that laser contacts could be easily 'manufactured' in great quantity. I'd like to see laser contacts score 10X higher than a 10 GHz qso as well, after all, these qso's generally take much longer to make because of the precision of the aiming equipment needed. I'd like to see Laser VUCC standards lowered so that 3 QSO's with surrounding grids counts for VUCC-after all, these contacts are much harder than microwaves.
