>>> I would be surprised if the SCS modem has the horsepower to
implement multi-mode busy detection with a pure software upgrade,
but lets assume for a moment that this is technically feasible. SCS
would expect to be compensated for the cost of developing, testing,
and deploying this upgrade. Why would current SCS users decide to
invest more in a proprietary hardware solution when a free software
solution - SCAMP - is imminent? Knowing the answer to this question,
why would SCS undertake the development?

>>>I am thrilled with the incorporation of busy detectors in SCAMP,
and pleased that Winlink saw fit to make this investment; it is the
only viable solution to the hidden transmitter problem that allows
semi-automatic operation to peacefully co-exist with person-to-
person operation. My relevant expertise is in system design and user
interface design, not detection algorithms -- otherwise I would be
contributing more directly.
