Hello all. First posting to this reflector. I finally feel like I know a little bit about something. I was briefing the Southern AZ DX Association on the most recent EC proposed regulation by bandwidth plan. I was questioned by an astute listener as what happens to the CW-only sub bands for the Technician (P) class operators on the HF bands. Even if the ARRL or other entity is authorized to define HF band plans, the FCC surely must still regulate the frequency authorizations for license classes. How does sub band plans regulated by an entity other than the FCC remain de-conflicted from FCC licensing privileges? Does the amateur radio-based regulator recommend and coordinate adjustments to FCC license frequency bands as part of the process?

Just when I thought I had it figured out, I don't. Hope someone can help me.

Looking at the summary charts in the original bandwidth proposal made public in August 2004: http://www.arrl.org/announce/bandwidth.html And the one most recently announced: http://www.arrl.org/news/stories/2005/04/13/1/?nc=1 I'm confused.

In particular, where will SSB (3 kHz) be permitted? And will digital SSB (3 kHz) be in the same segments or will it get more?

The August 04 proposal said the limits for 3 kHz (digital and analog) would be: (with no automatic control)

1800-2000 3725-4000 5 (6 - 2.8 kHz channels) 7125-7300 10 (none) 14150-14350 18110-18168 21200-21450 24930-24990 28300-29700

The recent EC version has limits for 3 kHz and 3 kHz with automatic control. I've been assuming that 3 kHz means digital or analog, maybe I'm not understanding it.

The chart at the bottom of the newest article doesn't make it clear that 3 kHz with automatic control means digital only (no SSB). Some people see that and think SSB will be allowed in those segments. Also - see the notes below.

1800-2000 3 kHz

3620-3635 3 kHz w/auto control 3635-4000 3 kHz *** this suggests SSB goes down to 3635 instead of 3725 ***

5 (6 - 2.8 kHz channels)

7100-7105 3 kHz w/auto control 7105-7300 3 kHz *** this suggests SSB goes down to 7105 instead of 7125 ***

10135-10140 3 kHz 10140-10150 3 kHz w/auto control

14100-14112 3 kHz w/auto control 14112-15350 3 kHz *** this suggests SSB goes down to 14112 instead of 14150 ***

18110-18168 3 kHz

21150-21160 3 kHz w/auto control 21160-21450 3 kHz *** this suggests SSB goes down to 21160 instead of 21200 ***

24930-24990 3 kHz

28120-28189 3 kHz w/auto control 28189-29700 3 kHz *** this suggests SSB goes down to 28189 instead of 28300 ***

QRV some clarification. (and whatever the answer, I think the web article needs to be clearer)

Thanks!
