Mark, I did not see any response to your bandplan proposal.
Some thoughts that I have: - I would have a digital area on each band (including WARC bands) for suggested mixed mode activity based upon FCC mode allowance. - Because we have gravitated toward the bottom of the bands with CW and the top of the bands with SSB voice, it seems to me that having digital near the dividing point between the data/RTTY and voice/image areas makes the most sense. - If we continue with the current FCC rules, Extra Class licensees will be able to operate Data/RTTY at the upper end of the subband and Voice/Image/FAX just above that point. Eventually, there will only be Generals and Extras on the HF bands anyway. - There could be an alternative area for General Voice/Image/FAX but even with the recent rule changes, aren't the commonly used Image/FAX frequencies still going to remain outside the General Class area? - By the way, with the new rules, I would guess that we will be able to use narrow image on the 30 meter band 73, Rick, KV9U Mark Miller wrote: >Rick, > >I have been working on such a plan.
