I would contact the repeater Admin / sponsors. In this case it’s via the website hamradios.ca
VE6GIE and I contacted him last fall and there was no update on when things were going to be on the air.
I know the issue in this area is that it’s a lot of reserve land and even AFRRCS and TELUS have coverage issues in the Bragg Creek / Redwood Meadows area.
I would also talk to Jay911 to see if he can reach out to the sponsor.
If the pair is off the air, and has been for a year, perhaps you should contact VE6AFO and ask that the pair be given to a HAM or group in the area that will make use of it.
I'm not involved with the Bragg Creek "club" if there is one.
I do know that Joop had a hell of a time convincing anyone to let him put up a tower in the area. It's not so much the First Nation as it is landowners and bureaucratic/political red tape, as far as I recall. I believe the existing towers are all full and nobody wants to let anyone else come join the party, and somebody has come up with a reason why a tower can't go up on any new site that has been proposed - ground's too unstable, not zoned properly, etc etc etc.
On the topic of the UHF EIT machine as it appears in RepeaterBook - if you'll allow me to pick nits for a bit, it's not in Cochrane. The "Notes" field says Richards Road x Range Road 265. (That's got to be a typo - it's either Township Road 265 or Range Road 65.) From where it's plotted on the Google Map on the repeaterbook.com page, it's at the junction of Richards Road and Highway 40, which is well inside the Municipal District of Bighorn, and several dozen kilometers away from Cochrane. The two closest towns are Waiparous Village and Benchlands. I'm not surprised people can't hit it from Calgary - you'd be lucky if you could get it from the 1A west of Cochrane. The location of this site is a dozen or two km south of MKGBRD (I forget the repeater but it's the one we use(d to use) on car rallies and is co-located on the FireNet Mockingbird Hill site).
On topic for the thread: No repeaters currently active adequately cover Bragg Creek or Redwood Meadows.
