Using the Caiman II with Asynch-1, and has been working well for a quite a while. Windows 7 current drivers.

I am getting a strange beep-beep-beep-beep now and then. I have heard this sound on various electronics years ago.

Tried both Anker battery and the Caiman power supply.

I am supposed to be Sunday at the Village Vanguard.. not tonight.

Thanks for any ideas
