It appears that this issue is once again generating oceans of
misinformation surrounding small islands of fact.
Points:
(1) No one will lose anything! The CW bands are not "going away".
(2) CW will remain an authorized mode for all bands and all amateur
frequencies. Ref: FCC part 97 rules, section 97. See 47 CFR
97.305(a). The correct mode designator for "CW" is 150HA1A, which has a
nominal bandwidth of 150 Hz.
(3) Each "exclusive CW segment" already includes authorizations for RTTY
and data transmission. Data transmissions must use publicly documented
formats and codes. There are some additional rules that apply to
undocumented codes, but for the most part, they are also permitted with
some additional reporting requirements and restrictions that must be
observed.
(4) Currently authorized CW, data, and RTTY modes are already, by
definition, narrowband emissions. FSK (RTTY) and data emissions must
be limited to a maximum data rate of 300 baud (excepting the 10 meter
band, which permits 1200 baud rates) with a maximum mark/space shift of
1 kHz for all MF and HF bands, including 10 meters. The vast majority
of stations use 170 Hz shift.
After reading the petition, I do not see any significant change between
the proposal and the part 97 rules as they exist today. The only change
would appear to be in the terminology used to describe the modes, for
example changing existing descriptions to "symbol communications".
There is, however, one change proposed that would expand "conventional"
AM transmissions between 1.8 and 29.7 MHz to 8 kHz bandwidth (2 kHz
more than allowed by current rules), and to 20 kHz bandwidth on 6
meters, 2 meters and, and 1 1/4 meters, and even higher bandwidths at
430 MHz and higher. I am not commenting on this portion of the petition.
But, returning to the original "scare" message, my opinion is that the
petitioner is in error as to the supposed point of the issue concerning
CW subbands, and I would not be surprised if the filing is rejected by
the FCC.
FWIW
