Mornings are usually the best time to hear tropo...especially before 10:00 a.m. local time. One example of this came three years ago, on August 2-3, 2010. The evening of August 2 featured mostly Indiana FM and NOAA Weather Radio stations. On the FM side, WQTY 93.3 Linton was logged and recorded, along with WXK72 162.400 Putnamville, which was a regular on 162.400 during the summer months at my suburban St. Louis location in 2011 and 2012. The other NOAA Weather Radio stations from Indiana heard were WWG72 162.425 Georgia and WWG83 162.500 Edwardsport. On the morning of August 3, I was able to hear KEGI 100.5 Trumann, AR, which is about 20 miles from Jonesboro, the original city of license. That same morning, I made this recording of KOEA 97.5 Doniphan, MO, which serves the Poplar Bluff market. August 19, 2010 was also another decent opening, getting this recording from KCKC 102.1 Kansas City, MO before changing its name to Alice. Sister station KMXV 93.3 also came in with a near-local strength signal. Swinging the antenna to the north, I also pulled in this one from KROC-FM 106.9 Rochester, MN (I've also caught the AM on 1340 on several occasions). I also recorded this from a station I use as a barometer for conditions into the Ottumwa area, KTWA 92.7 Ottumwa, IA. I've also caught the other three stations owned by Radio Ottumwa, KKSI 101.5, KRKN 104.3 and KBIZ 1240. I also nulled out the semi-local on 100.7 to hear KMZU Carrollton, MO. That year, August 4 was a good day for TV DX; I was able to get these captures from WCLJ 42 and WIPX 27 (63) out of Bloomington, IN.
Other memorable August openings include one in 2009, when I logged several Missouri and Iowa DTVs on August 24-25. Here's just a few of these video captures:
August has also been the latest I've logged E-skip on FM and TV at my location during the summer months. The most notable August E-skip opening was on August 4, 2004, when I logged seven new Canadian FM stations (mainly from Quebec) and WMOO 92.1 Derby Center, VT. On the TV side, I would add WCAX 3 Burlington, VT and CBFT2 3 Mont-Laurier, QC. E-skip, in my area, usually winds down in early August, and transitions to tropo. I've had a few off-season openings for E-skip, most notably on December 31, 1994 to Utah and Idaho, and on January 27, 2004 to the Rio Grande Valley, but in my area, the peak months for E-skip are June and July.
