[arm-allstar] Question about timing/responsiveness

[Doug Crompton]

Chuck,

 To start with the drop outs. This is more than likely an Internet problem and that would be the first place to start looking. Not knowing anything more about his system like what the Internet connection is, etc. It would be hard to suggest anything.

The other problem may or may not be related to a poor connection. When the PL input to the repeater  drops it should immediately drop the COS signal. The first place to check would be to make sure this is happening. If there is some kind of delay in the repeater and COS is staying true then it would have nothing to do with Allstar. When I say "true" that could be a high or low depending on the configuration. Put a meter on COS and key into the repeater and see how it follows.

Again not knowing his configuration it is hard to know what is actually happening. Is another controller in the loop? The best and simplest way to use Allstar as a repeater controller is to do it exclusively. The input PL drives COS  and the PTT output drives TX PTT and TX PL. All the timing, ID's etc. are done in Allstar.
