I envisioned sending real-time or near real-time traffic data Both the gateway and the repeater still seem to be operational: $ traceroute $_ traceroute to augs-gw.tcman.ampr.org (44.94.9.14), 30 hops max, 38 byte packets 1 10.38.224.1 (10.38.224.1) 847.710 ms 199.402 ms 434.667 ms 2 msp-hub1-gsr-b-pos5-0.mn.rr.com (24.26.161.37) 12.705 ms 28.341 ms 10.236 ms 3 mplsmn01-rtr1-pos-2-0.mn.rr.com (24.26.161.1) 11.978 ms 11.121 ms 12.244 ms 4 acr2-sonet2-1-0-0.Minneapolis.cw.net (208.174.1.129) 11.946 ms 12.663 ms 13.693 ms 5 acr1-loopback.Chicagochd.cw.net (208.172.2.61) 20.782 ms 22.097 ms 19.945 ms 6 corerouter1.WillowSprings.cw.net (204.70.9.135) 21.420 ms 22.567 ms 19.957 ms 7 bordercore2.WillowSprings.cw.net (166.48.22.1) 22.182 ms 22.270 ms 22.152 ms 8 concentric-networks.WillowSprings.cw.net (166.48.23.250) 23.811 ms 23.983 ms 23.470 ms 9 a14-0d603.tran1.chi-il.us.xo.net (207.88.50.129) 26.410 ms 22.372 ms 21.998 ms 10 ge5-3-1.RAR1.Chicago-IL.us.xo.net (64.220.0.189) 23.795 ms 22.924 ms 31.848 ms 11 p0-0-0-0.RAR2.Chicago-IL.us.xo.net (65.106.1.86) 22.553 ms 23.419 ms 21.948 ms 12 p1-0-0.RAR1.Dallas-TX.us.xo.net (65.106.0.34) 46.553 ms 46.272 ms 48.873 ms 13 p6-0-0.RAR2.LA-CA.us.xo.net (65.106.0.14) 105.908 ms 75.908 ms 76.259 ms 14 ge1-0.dist1.lax-ca.us.xo.net (64.220.0.99) 80.012 ms 77.945 ms 75.461 ms 15 a2-0d2.dist1.sdg-ca.us.xo.net (206.111.14.238) 79.769 ms 81.098 ms 83.312 ms 16 209.31.222.150 (209.31.222.150) 84.804 ms 83.669 ms 82.825 ms 17 206.111.14.118 (206.111.14.118) 114.955 ms 84.460 ms 85.300 ms 18 node-b-msfc--ucsd-gw.ucsd.edu (132.239.255.141) 86.153 ms 85.358 ms 88.919 ms 19 132.239.255.163 (132.239.255.163) 85.435 ms 86.405 ms 84.444 ms 20 mirrorshades.ucsd.edu (128.54.16.18) 91.220 ms 87.415 ms 86.804 ms 21 augs-gw.tcman.ampr.org (44.94.9.14) 117.528 ms 120.398 ms 212.582 ms $ IIRC, the repeater is on 444.400/449.400. If you listen with a standard NBFM rx (to the output on 444.4), it sounds like the squelch breaks every now and again. Two things would make me lobby to keep the amateur stuff distinct from any free-net: o the content restrictions that apply to ham traffic (no commercial, offensive, music etc etc etc) o the *huge* speed disparity, even between a 1Mbps 802.11 connection and a 56Kbps one. -- andyw at pobox.com Andy Warner Voice: (612) 801-8549 Fax: (208) 575-5634
