Just a quick post to note that the Navajo Nation's KTNN 660 has been off-air day/night for a few weeks. While previous extended outages seemed to involve their Flexiva transmitter, they now have a Nautel main in addition to the more troublesome GatesAir unit. The non-technical person who answered my email inquiry explained that they're still troubleshooting the problem, and believe it's in 'the antenna system' (phasor or ATUs most likely) and are eliminating the transmitters. That's slow progress, unfortunately. KTNN's programming continues on KTNN-FM, a class C2 facility which doesn't cover the reservation fully, and on a web stream.
