[aprssig] 6 meter APRS (KA nodes?)

[Bob Bruninga]

On Second THought (about 6m)...

Maybe we should make these digis be KA PACKET NODE capable too?

Rationale:

1) we will never have wall-to-wall mobiles on 6m network.

2) So what else to use the channel for?

3) 6m is a great fixed-location long range channel ideal for
EOC's and other fixed emergency sites for fixed-to-fixed comms where general purpose comms to all mobiles is not needed.  Since 2m and 70cm is so valuable for emergency operations, using 6m from the EOC for fixed comms, minimizes co-site QRM.

4) Duty cycle of a few mobiles should be able to share with some KA node activity..

Although it would be nice to have KA nodes at each digi, I think that you can use one digi to link between two KA nodes, so really, only every other digi needs to be a KA node, and the ones inbetween can be a simple digi...

What else is KA node compatible?  Do the THENET ROMS work?  AH but then they do not have WIDEn-N (now 6MTRn-N) simultaneous capability so would not be suitable..

Just thinking out loud.

Oh, and lots of base station rigs now have 6 meter capability, so this network does not need to be an orphan...
