    Update

    Today, KPIJ’s engineer agreed, at the request of KVRM, to “review” their power and antenna setup, keeping in mind KRVM’s assertion that KPIJ is somehow reaching Oakridge.

    Meanwhile, this afternoon in Oakridge, KAVE sounds much better.

    There’s some whooshing noise from the car a/c blower. Disregard.

    To be continued.

    Is “sporadic E” a possible factor in this interference situation?

    https://en.m.wikipedia.org/wiki/Sporadic_E_propagation

    “As its name suggests, sporadic E is an abnormal event, not the usual condition, but can happen at almost any time; it does, however, display seasonal patterns. Sporadic E activity peaks predictably in the summertime in both hemispheres. In North America, the peak is most noticeable in mid-to-late June, trailing off through July and into August.”

    Another anecdotal observation from Oakridge.

    Yesterday 6/29 just before 2PM, KAVE was shut down for about 10 seconds. KPIJ came in very well.

    Epilogue

    There seems to be general agreement that the “interference” occurs seasonally, at the peak of the sporadic-e aka e/skip season in June.

    KPIJ 88.5 reception at the KAVE 88.5 transmitter site in Oakridge while KAVE is down.

    Even KPIJ Fringe coverage does not reach Oakridge…maybe it’s because both sites are line of sight

    “maybe it’s because both sites are line of sight”

    No they aren’t.

    See my post on the previous page. KAVE is in a hole.
