Are there any components of ADS-B that might be transferable to a
totally "new", UHF APRS system. We recognised years ago that ax25
has severe limitations and that better systems exist. Whilst we'll
never change ax25 and 1k2 aprs it should be possible to devise an
alternative network using new protocols to which users can migrate
over a period of time.<br>
