[P25nx] Connect to astrotac

[Larry D'Anna]

 I am working to connect my p25NX. to an Astrotac comparator to link with other repeaters i have on the comparator 
Connecting to a A quantar via V.24works just fine but when i connect to comparator i can see my out going transmission on the dashboard but no return transmissions . When i changed talkgroups i do not get the voice confirmation nor the end of transmission courtesy tone

Has anyone had experience with the astrotac comparator and what is the configuration that is found to work

Thanks
Larry
