This is the time of year for a subsidiary peak in both Tropospheric and Sporadic E DX. I noticed quite a few stations coming in on first adjacents to locals (even those using IBOC). On 101.7, I almost was convinced that it was Sporadic E, as they were inconsistent and more than one station was heard. WHZZ 101.7 Mike FM Lansing, MI and CKNX-FM 101.7 Wingham, ON were both coming in alternately. Also WLEW-FM 102.1 Bad Axe, WCKY 103.7 Tiffin, OH, WBCT 93.7 Grand Rapids, MI, and WVIC 94.1 Jackson, MI were all heard on a moving car radio. Some seemed very strong, which also suggested Sporadic E.
