Hi guys - I want to make sure I didn't miss this somewhere along the way...it may be old news but I don't think so. I was headed over to Morgan late today and decided to see what this "hot ac" thing was about on 97.9 and I noticed that something seemed like it kept jamming the signal. A dead carrier kept appearing and sometimes taking over the frequency. Then I discovered the same thing occurring on 99.5. After arriving back home I decided to look it up and indeed both KJMY and KBZN have Park City boosters and both are up on Lewis Peak above Coalville which would make sense for the areas I was getting signal outages....I figured it had to be something on Lewis Peak doing this. So it looks like the boosters are on but they're both dead. Just dead air. KBZN was just a carrier. KJMY was a carrier with a stereo pilot. I just don't recall if this is something new or not but I do know these stations will be a lot more receivable up here in Evanston via their boosters on Lewis Peak. When KCWW 88.1 is off the air here, the translator on Lewis makes it into Evanston.
So am I right? Are these boosters new? Are there more to come?

KBZN for a long time (when it was an NAC station) included Park City in its legal ID. They've had a booster there since '97. My 99.5's booster is newer, dating only back to 2007, but I think that was the second try at it. If I remember correctly the first permit expired unbuilt.
Most of the major Farnsworth stations and a couple of the Humpy's have boosters in Park City now. (Something to do with adding Summit County to the Arbitron metro for all reports I think.) There are KUER (CP), KRCL, KODJ, KXRK, KZHT, KBZN, KJMY, KSFI (CP), KEGA, KJQN, KTMY (App, not approved), and KOSY.

Well an update to this situation....was through the same area on Friday of last week and it looks like KBZN's booster has its audio back. KMJY does not. However, I noted some wierdness. Maybe these guys need to get with the humpy folks who sync THEIR boosters. KBZN seemed to sound fine when you were picking up ONLY the main or ONLY the booster. But when the radio was picking up both at the same time, it seem really loud and overloaded and almost distorted. All the humpys have SEVERAL boosters down there that they sync with the main and they don't have these sorts of problems. KBZN has ONE. You'd think they could manage to make it clean. Not sure about these other boosters although it DOES make sense now why when picking up KODJ's analog with my roof antenna at home.....it seems to be echoey. Now I know why. My antenna is picking up the booster and the main. Once if kicks into HD, it's fine.

Ooops...correct myself before someone else does. KMJY = KJMY  |

I had never considered how far the Park City licensed boosters would make it out until just now, but you're right that it should be very possible to pick them up from Evanston. If the Farnsworth station care about the Wyoming listeners, they should make an effort to get everything in sync. Close to the boosters themselves it should be less of an impact (theoretically) due to the capture effect. The signal strength from the Farnsworth mains and the booster looks fairly close when you get to that distance according to the predicted contours. In theory, fixing it should be a simple matter of math. Electromagnetic energy travels at a constant speed. Figuring out the distances of each hop should give you pretty much all you need to sync everything. That works well for the Humpy main/boosters where the reference points where you want to have all signals arriving at the same time are pretty much the same distance from the main. I'm not so sure about going the other way or what would happen if you compared the timing of a Humpy booster and the main 20 miles east of the Wasatch. Since the boosters don't point that way, it doesn't matter. If they did, they might get all wonky, I'm not sure.
A similar problem like what you described near Morgan had been notorious on 107.9 around here. Not sure if it still is, but it used to be awful and sometimes unlistenable with signals a tenth of a second apart being played simultaneously. Maybe Big Rog could let us know what kind of discussions inside Millcreek might have gone on over the years. I imagine they would have spent some time worrying about it.
