First and foremost, John, let me wish you the very best in your
battle with cancer. Know that you're in our thoughts.
As for the attachment, it does demonstrate progress. Steve has
admitted in writing that the hidden transmitter effect actually
exists. Its taken years, but he evidently now gets it.
The following quote is particularly revealing:
"Again, since most of the current operations under local and remote
control are using a protocol over 500 Hz, which requires such
operations to be placed in very restrictive band segments, the
problem is that there is now not much incentive to develop such
signal detection techniques for existing or future protocols since
there is little band space to use them."
In other words, "we're not motivated by the need to avoid QRM'ing our
fellow amateurs; if you want us to deploy busy frequency detectors,
you'll have to bribe us with more band space for semi-automatic
operation".
Its now clear why the two-year-old SCAMP busy frequency detector has
never been incorporated into WinLink servers.
