[arm-allstar] Very low audio.

Tue Apr 2 10:11:38 EDT 2019

Doug,

     I've never had the PLTone problem either. I'll try the mod that you
suggested to Fred in the next few days. Looking at the URI schematic, I can
see that the voltage divider resistor values may be a bit drastic and could
account for the problems that Fred and I have encountered. The trouble is,
if it works, you may have just ruined my justifying buying a new Alinco
radio ;-).

    Also, you mentioned that the URI might not be the best choice in and
USB device at least in the near future. I've got one I'm using now but what
else would you recommend? As I've mentioned in previous posts, I'm putting
together a radioless node as well. I'll have a URI to use in one project
but would need another FOB to get them both up and running. The radioless
node might be a good choice for "the shack"
