   I have spoken with many that think you can lump a ton of
transmitters on the same frequency without interference if
you use "spread-spectrum communications methodology" but
collisions will occur, it is not a panacea.

   So all old HAM radios shall be junked for the massive
improvement in my ability to talk with my radio friends
within 25 miles of the repeaters, why again?

   When did "radio telegraphy gave way to radio telephone"?
I still love and use "CW" and it's use is growing.
You can talk around the world with "a hard carrier on 51.5 MHz" with
10 Watts.  What are you trying to do?

   A "special communications facility for the privileged few" that bothered
to study and take a test, rich and poor alike, old and young, hes and shes.

   Someone has been out of HAM radio too long, it seem to those still in it,
it is working just fine including Dstar, several types of packet radio and the
conventional modulation schemes.  (many forms of digital modulation are common)
   I fail to see any problem.

                  every opportunity to TAX and it shows.  (while giving very poor service)
