[CW] New FCC Proposal for Rule making

[D.J.J. Ring, Jr.]

Janis AB2RA made comments:

This is a powerful well funded coalition. The ARRL successfully contested
the Broadband over Power Lines initiative. That was a clear cut case
though, due to the potential interference being directly in the amateur
spectrum. This time, its in Part 90 spectrum adjacent to our Part 97
spectrum.

In this case, the primary issues are raising the noise floor and overload
experienced by certain SDR radio designs which do not have a narrow high Q
RF preselector (one example being the popular IC-7300, for instance).

The rise in noise floor has been well understood for some time. This white
paper by W8JI the designer of the most popular amplifiers and many pieces
of test gear is a good summary: Mixing Wide & Narrow Modes, W8JI:

However, a more immediate threat to RTTY/DATA/CW is the one posed by
RM-11708 and WT Docket No. 16-239.

This may be acted on very soon. The ARRL Board of Directors meets next
weekend. Please contact them to endorse their ARRL HF Band Planning
Committee's work as an immediate solution to this threat. You may want to
comment on the commercial spectrum action also.

They are. They were talking about it in today’s weekly ARRL Letter.
