Rick, My expert on the subject says that limiting digital bandwidth to 3 KHz will kill digital experimentation. (which is what I thought we were trying to encourage with this effort) He quotes laws of physics that balance robustness against throughput. He says that current modes are about as good as we are going to get with a 3 KHz limit. My degree is in math-physics and he is over my head. :-) Coy -- ARRL West Gulf Division Director Coy Day, N5OK 20685 SW 29th St Union City, OK 73090 n5ok@arrl.org 405-483-5632 -------------- Original message from k5ur@aol.com: -------------- Hi Coy: Yes, I've had one comment about that issue. It was from an individual that likes to pass traffic and is one of the long time NTS guys. I bounced the discussion around a bit and asked him some questions to try and better understand, specifically if he thought we needed a segment for that group, too, like we made for the automatic group (not semi-automatic). I asked him how many people would really need this provision given the digital scene today and after some more discussion, I was left with the impression very few. In any event, it did leave me wondering. I asked him to outline his points and get it to me, but I have not heard back from him yet. Like I said, that's the only comment I've received on that issue. 73, Rick - K5UR -----Original Message----- From: n5ok.ok@att.net To: arrl-odv <arrl-odv@reflector.arrl.org> Sent: Wed, 04 May 2005 20:25:52 +0000 Subject: [arrl-odv:12268] 3KHz Wide Digital If I understand the EC's proposal, the digital modes will be limitted to 3KHz at HF frequencies. I'm hearing from my digital experts that this isn't enough bandwidth to keep from severly limitting the data rates that can be obtained. Anyone else h! earing this?
