[arm-allstar] repeater linking setup

[Doug Crompton]

Larry,

 This is a common problem when using a remote node to a repeater that does
not have Internet. Technically turning off the ID at your node would make
it illegal as all amateur transmissions need to be identified every 10
minutes. ID's are only local, they don't go out to other connected nodes
but they do go out on your node radio via RF and would go to the repeater.

As far as the ping-pong effects the first thing you want to do is turn OFF
the courtesy tone in rpt.conf - nounkeyct=1 You may also want to reduce the
hangtime setting in rpt.conf. You need to restart Asterisk after making any
changes.  If you still have ping ponging you can try adjusting the
rxondelay in simpleusb-tune-menu. This setting delays your COS response. It
is set in 20ms increments so a setting of 5 would be 1/10 of a second, a
setting of 50 would be 1 second. However don't make this too long as it
will cut off the beginning of transmissions..

To eliminate other from hearing your CWID and  this is your repeater or you
have an understanding with the repeater owner you can do the following:

The simplest way is if it is your repeater and the repeater call is the
same as your call. Just tuen off the ID at the repeater and let your node
ID for both. Not letter of the law legal but it is ID'ing correctly for
both.

If that doesn't work for you the repeater can be made to have the PL follow
the input not the output. That is the repeater keys on input PL and the
repeater output PL drops when the input PL drops. In this case users would
not hear the repeater tail or ID and not your ID.  Users could disable
receive PL and still hear the tail if desired.

Another option is to add a PL decode board at the repeater that follows
input and not output and is the same PL as you are transmitting to the
repeater but different from the normal PL of other users. In this case the
users would still hear the repeater tail and ID but not yours since your
signal follows the input PL.  The repeater would decode two PL's, yours
would only key the repeater output when it was present. The other users PL
would key it but also assert the tail and repeater ID if present.
