I have a few questions regarding the current state of packet radio. 1) Where can I get lots of information about it? The only documentation I have so far is the November CQ magazine. 2) What is the maximum size of an AX.25 packet? 3) What plans are there for the next level of network software to be add to the basic network layer of error checking packet communications that has been provided by AX.25. 4) Why has the FCC limited H.F. data transmission rates to 300 baud? I'm aware of the the limits on 2 meters and above. 5) I'm particularly intersted in H.F. (D.X.) packet radio. How much success has been made on the long distance bands? I'm aware of the digirepeater capabilities of most of the packet boxes, however I'm thinking more of long distance point to point transmission because of the sacrificed speed that digirepeating inherently requires. Forgive my ignorance if I have made obvious blunders in the statements above I've only recently started looking into packet radio. From the few articles I've seen in CQ, this could be very interesting. One last thing-I'm not a licensed ham--------yet. Thanks in advance ------ Steve Upp ...!ihnp4!gargoyle!sphinx!supp
