My disdain is for a shoddy implementation that transmits on
frequencies without first verifying that they are clear, John.
Compared with the alternative, which is to shut them down until they
comply with 97.101 like everyone else, 3 KHz on 14 MHz is pretty
generous.

That's not a competent defense, Walt. The fact that WinLink's
functionality is unique does not diminish the QRM that WinLink
generates. Rather than confront this head on -- perhaps by confining

Dave,
In the ARRL's defense, when they looked at WinLink at their Board Meeting,

was nothing else on the technology front that could do what WinLink was doing.
And until PSKMail came out, there WAS NOTHING to equal WinLink.
So if everyone "hates" WinLink, why don't we see hundreds of PSK

The ARRL's explicit endorsement of WinLink has made it easy for the
WinLink organization to ignore the egregious defect in their
implementation. Convincing the ARRL to take a constructive stand on
QRM from semi-automatic stations would be a more appropriate first

Leigh,
Within the automatic sub bands, they would not have to have any
detection and would still be legal. When the rules were drawn up, the
technology had not been invented to have busy frequency detection, at
least not for amateur radio. But that all changed a couple years ago
when Rick, KN6
If this is true, wouldn't it be a major reversal from past FCC
recommendations?
My understanding was that some time back (decade or so) the FCC wanted
to regulate by bandwidth, rather than mode, and the ARRL strongly
opposed it at that time and the idea was dropped.
