[arm-allstar] Flashing green LED

[David McGough]

Hi Larry,

The green LED indicates USB activity. The speed of the flashing is an
artifact of how the HamVoIP driver always keeps the c-media sound chip
running in full-duplex. This resolves an issue with TX audio being 
chopped-off immediately after the node is keyed and was included in the 
10/26/2017 software update---over a year ago.


Turbo mode doesn't change this. As for it being brighter?? No idea about 
that.

I recommend putting a piece of electrical tape over the LED or maybe paint 
it with dark finger-nail polish, if needed.
