In the meantime, I'm still getting 10135 PSP Coudrsprt constantly on BRAD31 and BRAD41.
FWIW, when sites first started coming online down my way, there was a lof of traffic on the PSP Mansfield talkgroup. That has gone away now. Although it cannot be confirmed, the speculation by some other folks is that it was SRND folks doing testing. Since they were using radios programmed for PSP in the field, they would have had to choose a talkgroup that wouldn't be live anywhere, yet. In your case, their options are dwindling now and Coudersport would be one of the last stations to come online. So, they may be using that talkgroup now for chatter related to rollout work or testing. They can't do that on the suspected tech talkgroups if they are using radios being deployed for Troop use.
