[aprssig] Broken digis (Ohio to Oklahoma and everywhere inbetween)

Hi James and everyone else,
   I agree with James that some digi owners might take their system down.
But, would that really be a bad thing it they don't support the new system.
What good does it really do for the APRS community? A few locals that are
using the old system will be able to use the digi. But, anyone that is
traveling will not be able to use the system. 
   James, we are in the process of putting up another digi for here in
Colorado Springs. Hope, that this will fill in the coverage for I-25 from
Wyoming to New Mexico.

TNX & 73,
Dave N0EOP

As someone that runs 4 digipeaters it easy for everyone here to say you 
need to that you need to do this. Has anyone helped invest in a 
digipeater? if so Thank You!!! I haven't seen any money yet from all the 
users that use my equipment on daily basis and lets not forget when 
Dayton comes around and there is even more users. Trust me, I have allot 
of my own money involved  in building a network of digi's Indiana. Not 
everyone of them  just mine. I have  them set to the new  paradigm 
WIDEn-N , SS stuff. Again, you have to put yourself in the shoes of a 
digipeater owner. Securing good sites nowadays is expensive... Everyone 
will change over eventually, stop gripping already or you may find that 
instead of trying to help the situation you in turn make and worst and 
lose the digipeater all together. P and M too long and people will 
simply switch it off. And for the record I've been around for 12 + years 
on APRS, I've read everything, changed everything when new things came 
down pike. Been there done that and Stan wrote book about it... :) Stan!!!!!
