[arm-allstar] Remote node causing issues

[Doug Crompton]

Mike,

 Not sure if you modified the 888's yourself or maybe bought them modified.
In any event I believe what you are experiencing is RF feedback. Are you
using an external antenna? The Whip that comes with them is very poor and
has a rather high SWR. I send you directly a PDF with more info...
