The FCC has granted the ARRL's request to allow certain
TDMA transmissions on the amateur bands, but denied a petition for
reconsideration of the Commission's earlier decision on Broadband over Power
Lines, or BPL.
According to the ARRL Letter, the FCC OKd a
temporary waiver to permit the use of single-slot Time Domain Multiple Access
transmissions on amateur frequencies above 30 MHz. A proposal to permanently authorize
amateur use of this digital mode is currently pending before the Commission,
suggesting that its eventual approval is likely.
