[Elecraft] KK7P KDSP2 module

Thu Mar 27 13:10:01 2003

Probably the biggest reason for keeping the aux bus tightly held, is that if it is published, then it has to be maintained. If company x designs a product on the aux bus protocol being just so, then it has a grievance if elecraft changes it.

As it stands now, if elecraft wants to change it, it is a matter of its own firmware, and upgrades that its own customers apply.

Anyone who reverse engineers it and bases a product on it does so at their own risk, and elecraft does not have to worry about keeping them happy.

Based on their excellent track record, I'd want them to keep the new stuff in-house (and the revenue to keep them perking along).

They decide themselves to publish it, then fine.

Just my .02 & 73,
Guy, K2AV.
