My area will sometimes broadcast with a super group patch. I have found if I have the Super group locked out that I will not hear the traffic on subgroups that I do not have locked out. I would like to see if you have a talkgroup locked out and it keys up as a patched supergroup that it unlock and allow the audio to be decoded for the duration that the supergroup is enabled. That way if the group I have locked out is talking I will not hear the traffic but if the group is talking as a supergroup I will hear the traffic.
