[arm-allstar] Random Keyups

[Doug Crompton]

It is hard to say what might be causing this without some further testing.
If you go into the Asterisk client there might be a clue in what you see
there. You would have to login immediately at bootup and enter the client.
At boot it does give your ID and IP address but that happens quickly after
boot and not be 2-3 minutes later.

There have been RF issues with the 888 and random keyups.. The RX/TX gets
in a ping pong loop. It is highly recommended that you not use the rubber
duck antenna on the 888 but rather an external one at least several feet
away or a dummy load for local node use. We have also changed the gate
drive resistor to the 2N7000 from a 10K to a 330 ohm. The 2N7000 is a
voltage driven device with a very high input impedance. Using the higher
value resistor works but also raises the opportunity for RF getting into
the gate. In general it is usually a combination of these things that
ultimately solves that problem if that is what is causing yours.
