Hi all,

Following up on my earlier post: this turned out to be a known intermittent
issue with the diffusion cabinet not fully handing off when switching between
the high-power diffusion amp (with preemphasis) and the GAB/3 for solutions work.

Fix: Disconnect the Ethernet to the diffusion cabinet, run cf, and it seems to
detect the GAB/3 normally.

Hope this saves someone a troubleshooting session.

Best,
