When I was in Calgary, a local ham John, VE6KQ, insatalled a VHF 1200bps regenerative packet repeater (DCD to key the repeater, so strictly packet) and it made a tremendous improvement to the packet activity in Calgary. Actually made the mode usable! I think someone quoted a four-fold improvement in throughput. It certainly has it's advantages over a simplex system ... if you can afford it :-) 73, Dan, VE4DRK ------------------------------------------------------------------------ Dan Keizer, VE4DRK Federated Insurance Company of Canada drk@fed-ins.ca 717 Portage Ave, Winnipeg, MB R3C 3C9 Opinions are mine and that's that.

Our first thoughts were 1200 baud on 2M, but now we're leaning toward 1200 and/or 9600 on UHF. A coupla questions: 1) In a moderately large metro area, does a 1200 baud 2M system get saturated quickly? We were concerened that we'd get great coverage, but that the thing would be 100% busy. 2) Has anyone successfully run both 1200 and 9600 on the same repeater system? I seem to recall something about this, but can't put my finger on the details. I hate the idea of investing in a 1200 baud- only system... 73, John ------------------------------ Date: Mon, 31 Jan 1994 19:40:52 -0600 (CST) From: Jeffrey Austen Subject: 9600 b/s frequencies and repeaters (was: 9600b settings) To: tcp-group@ucsd.edu > Has anyone successfully run both 1200 > and 9600 on the same repeater system? It would be simple to implement but it would also recreate just the problem we are trying to avoid: hidden stations. The 1200 b/s stations would not detect 9600 b/s activity and visa-versa.

At least I think so. I don't have 9600 on the air yet. The call is wb6ymh and I bet you could find out the particulars with a packet mail to wb6ymh@wb6ymh.#soca.ca.usa.na.
