Back in the early 90s three of us here in Vienna VA USA were running tcp/ip over 19k2 AX25 packet and it was OK for email and text browsing. 9k6 would have been too slow it seems to me. Was expensive at the time as we were using the Ottawa cards and kantronics D4-10 radios. We have been using 9k2 packet for the Marine Corps Marathon now for 2 years. Given we controlled the server we are able to use D700s on 9k6 just fine to check runners in and out of the aid stations. The server used a 9612+, AGWPE, and TelMGR to handle the connects. We are also looking at 9k6 packet for our local county emergency shelter communications on VHF and UHF. Talking to servers running various, and yet to be created, applications. In addition to WinLink 2k. The statewide digital traffic net does use sound card modes. 73, Tom n4zpt Vienna VA USA
