> Thank you for your comments.  As I suspect you know, this is not a new 
> issue.  The fact of the matter is that the 220SMA Band Plan for the last 
> 10+ years has had FM voice and packet as low as 222.06 MHz.  The 
> intensity of band use in Southern California made this necessary in 
> order to provide space for everyone.  Even with this condition the 
> impact on weak signal activities has been minimal.
> 
> The impetus for this revision was recognition that the digital community 
> was no longer using all the allocations they were provided during the 
> hay day of packet radio.  Reallocation of the band in this revision has 
> allowed us to move all of the non weak signal uses above 222.11 offering 
> a small guard band.  Several weak signal mode advocates participated in 
> the year long discussions that led to the current proposal, and all of 
> them agree that this is a workable alternative.  Some operators in 
> Southern California still object to moving FM off of 222.06 and 222.08 
> MHz.  Most of us feel that clearing the beacon and SSB zone is a major 
> step forward.

> An idea that was discussed during our review was the concept of SSB 
> operators suggesting a QSY "down" of 10 or 20 kHz from the calling 
> channel instead of "up", as is the norm.  The plan also encourages low 
> intensity (non weak signal) uses in the 222.12 - 222.15 MHz segment. 
> Typically these activities don't cause any significant interference to 
> SSB operations.

> Although the proposal has gone through several rounds of discussion 
> before getting this far, it is still subject to further consideration. 
> My personal opinion is that this is such a major gain for the weak 
> signal community, they should support it now and look for additional 
> opportunities to make further improvements in the future

> First, I can appreciate that Southern California has a higher amateur

> would hope that ARRL would consider the overall needs of the amateur 
> community of the entire country and thus their approach would be the one 
> that would be best for the band.

> Second, the line of reasoning behind encroachment of FM operation into 
> the weak weak signal portion of the 222 mhz band sounds scarily like the 
> rationale that commercial interests are using to take the band from us. 
> Reduced to the simplest form it is, "We need more frequencies. There are 
> more of us than there are of them. Let's take it." Surely there is 
> enough spectrum in the 222 mhz band for everyone and there should be 
> enough respect for each interest to allow space for each to operate 
> without the threat of interference.
> 
> Third, I did not know that a form of this band plan had been in effect 
> for over ten years and has had, as you point out, some effect on weak 
> signal operation in the region. If this is so, it is wrong and should be 
> fixed now.
