RE: transparent internet via radio

["John Feist" <aa6qn@pacbell.net>]

Yup, we have 56k here in San Diego on 70cm, been up for several years 25
miles point-to-point. Some folks up North are using 802.11b 6-7 miles at 6~7
Mbit.

See the AX25-HOWTO for information on tcp/ip over AX.25.

The WA4DSY modem will do 56 kbps (http://www.paccomm.com).  It operates
at 29 MHz and must be used with a transverter for the appropriate band.
Some hams in Slovenia have designed high speed equipment, see
http://hamradio.si/hid.html for some links.
