[arm-allstar] Node keeps rekeying up

[Doug Crompton]

Connecting a simplex node to a repeater requires some planning and always
the permission of the repeater owner. I will call this the "poor mans" way
to get Allstar on the repeater. The best way is having Internet at the
repeater and interfacing Allstar there either using Allstar as the repeater
controller or bringing it in on a port of an existing controller.

In the event this is not possible there are things you can do to make it
work reasonably well. I personally have a repeater that does not have
access to the Internet and I use a remote simplex node to provide full time
Allstar on that repeater. The key is to have the repeater PL follow the
input to the repeater not the output. Then your remote simplex node sees
keyups like they were coming directly from the input station to the
repeater and not the repeater itself thus eliminating the repeater tail and
ID from being transmitted out over Allstar. This would require a change at
the repeater. The downside is that the repeater users would not hear the
repeater tail or ID either if they were using tone squelch. You could add a
second PL so that one followed the repeater input and one followed the
repeater output so both repeater users and Allstar would be happy BUT if
this is a full time Allstar connection there would be no reason to do that.
The remote simplex node stays in duplex=1 with no other changes. Its
courtesy tone becomes the repeater courtesy tone and tail that the users
would hear. When the repeater unkeys it would either not have a PL or have
a PL that the remote simplex Allstar node would not respond to thus no
keyup loop.

When doing this you can set the repeater to have a short CW ID and let the
remote simplex node do a normal ID. Repeater users would just have to get
use to hearing it and observe the rules of Allstar - no quick keyups. The
key here is not being upset that Allstar is being added to the repeater and
accepting some changes. Many of the repeaters we have are not being used or
utilized beyond a few keyups a day. Adding Allstar could be a big benefit
but requires some education and understanding that things will change a bit.
