> Acting upon a subsequent request by the ARRL, the FCC issued an
> Order (WT Docket No, 12-283) on March 25, granting a temporary
> waiver to transmit communications on amateur service channels above
> 30 MHz using single time-slot Time Division Multiple Access (TDMA)
> systems. The temporary waiver was granted pending the resolution of
> a related rulemaking proceeding (RM-11625).  The waiver can be found
> in PDF format at,

> Currently, amateur stations currently are authorized to transmit
> messages using telephony and data emissions. The ARRL noted in its
> request that Amateur Radio Service licensees have recently
> established numerous narrowband repeater facilities using multiple
> time-slot TDMA repeaters and single-slot TDMA handheld digital
> transceivers in the 70 centimeter (420-450 MHz) band, but Part 97 as
> it currently stands does not permit amateur stations to transmit
> single-slot TDMA emissions on Amateur Radio Service channels above
> 30 MHz.
>
> The FCC stated in its Order that the purpose of specifying emission
> designators for the Amateur Radio Service "is to relegate the
> transmission of certain inharmonious emission types to different
> segments of the frequency bands, while still allowing great
> flexibility in the types of emissions that may be transmitted by
> amateur stations." In granting the temporary waiver, the FCC agreed
> with the ARRL, noting that the digital systems that radio amateurs
> have recently implemented are "compatible with existing amateur
> repeater channelization plans."
>
> The FCC also noted that allowing FXE and F7E as phone emissions and
> emission type FXD as a data emission "is unlikely to result in
> inharmonious emission types being used in the same segments of the
> frequency bands. We also conclude that allowing amateur stations to
> transmit these emission types is consistent with the basis and
> purpose of the amateur service, specifically to continue to
> contribute to the advancement of the radio art. We conclude that
> good cause has been shown for temporary waiver of Section 97.3(c)(5)
> to allow amateur stations to transmit emission types FXE and F7E as
> a phone emission and Section 97.307(f)(8) to allow amateur stations
> to transmit emission type FXD as a data emission. We therefore waive
> these rules accordingly, conditioned on the outcome of the pending
> rulemaking proceeding."
