George,

"NTIA has reviewed its assignments and has found that 5 channels are =
lightly used and could be used on a secondary basis by amateur =
stations...We also concur with NTIA's basic proposals that amateur =
service operations on these channels be limited to SSB-SC modulation, =
upper sideband voice transmissions only, with power not to exceed =
equivalent of 50 W PEP transmitter output power into an antenna with a =
gain of 0 dBd, or 50 W e.r.p.  Accordingly, we are amending sections =
2.106, and 97.303 of our rules to provide a secondary allocation to the =
amateur service on the channels 5332 kHz, 5348 kHz, 5368 kHz, 5373 kHz =
and 5405 kHz as specified by NTIA, and to require that amateur =
operations be limited to an effective radiated power (e.r.p.) of 50 W, =
and emission type 2K8J3E, upper sideband voice transmissions only =
centered on each frequency."
------------------------------------

So it seems from the last sentence above, that the actual indicated =
suppressed carrier frequencies of the five channels will need to be 1.4 =
kHz below the listed channel center frequencies (i.e., 5330.6, 5346.6, =
5366.6, 5371.6, 5403.6 kHz).  I wonder how well that will be recognized =
and observed by the amateur community.  The ARRL had better emphasize =
that point, as alien as it is to most hams.
