> 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

> Thanks for your timely response and explanation of the rationale for the
> proposal. Some thoughts came to mind almost immediately as I read your
> comments.

> First, I can appreciate that Southern California has a higher amateur
> population and may have higher usage of the 222 mhz band. However, this
> proposed plan is in conflict with the ARRL band plan for this band. I
> 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.
