I've tried IP over AX25 using 1200 baud on 2m FM (using PC rather than Empeg) and it is extremely slow. Ping times were measured in tens of seconds. The shared channel nature of amateur packet means that a 1200 baud link works out to a lot less when you consider that it's half duplex with lots of users and many packet collisions.

Also, for IP routing to work you'd need to always be in range of the same hub which on 2m limits you to tens of miles. If you just used AX25 rather than IP over AX25 you'd be able to roam further, but you'd still need to know a path back to your "home" node where your mail etc. would be stored until you collected it.

Don't forget that in the UK at least no 3rd party traffic is permitted unless it has been manually approved by a licenced amateur. This rules out receiving even simple things such as the subject lines of emails.

Sorry to be so negative.

Cheers,

Mark.
