[arm-allstar] My Node is auto kerchunking

[Doug Crompton]

Go into simpleusb-tune-menu. Select V - there will be lines at the boot
displaying COS input and COS composite. If that is showing KEYED when you
hear the keyup then the actual signal coming in on the COS line is
triggering the event. Perhaps there is a problem with the incoming COS
line.

Are you using usb or usbinvert in item J of simpleusb-tune-menu?

Perhaps the COS signal from your repeater controller is not going low of
high enough. If you are using usbinvert it must go low on signal and should
go down to very close to zero volts and above 2.5 volts with no signal. If
you are using usb then just the opposite.

Something is apparently triggering that line or it is sitting on the hairy
edge of transition.
