[Ham-80211] OT??? High power 2.4 GHz rules change

Hello, Marlon,

I would strongly recommend dropping the APC requirement for Spread
Spectrum.  It is difficult to implement and an impediment to further
experimentation.  Its initial implementation was unfortunate.

I believe the ARRL has appropriately come out in favor of dropping APC.
The exact wording of their petition to the FCC is:

ARRL, the National Association for Amateur Radio, also known as The
American Radio Relay League, Incorporated (ARRL), by counsel, hereby
respectfully requests that the Commission issue a Notice of Proposed Rule
Making at an early date, proposing the deletion of Section 97.311(d) of
the Commission?s rules, save for the first sentence thereof. The effect of
the rule change would be to eliminate an automatic power control provision
that has proven over time to be impractical of compliance; is unnecessary
in order to protect other Amateur Radio operations or the operation of any
licensed radio service sharing certain Amateur Radio allocations; and
which has unfortunately served as an unintended, but effective deterrent
to Spread Spectrum experimentation in the Amateur Service. In support of
its Petition, ARRL states as follows:

Thanks for asking for comment on this.  The ARRL has it precisely right  
this time.

I hope you do the right thing and recommend that APC be dropped.  Think  
broader public interest and not narrow special interest group and I think  
you will agree.

Thanks, and


Roger Rehr W3SZ
