The cable system for Whitesburg, Kentucky located in Southeastern Kentucky along the Kentucky/Virginia border was a wonderful source for far away signal both intentionally and by accident. The antenna system was atop a simple peak for the first 30 years before moving to one of the highest peaks in Eastern Kentucky. The early years were a five channel service:
2) ABC via WOWK (WHTN)-13 Huntington or WLOS-13 Asheville, NC and sometimes WKPT-19 Kingsport, TN. Huntington and Asheville were about 100 miles away and WKPT was 50 miles away.
3) Usually PBS via WKHA (KET)-35 Hazard, KY (30 miles) or WSJK-2 Sneedville, TN (70 miles) and sometimes WSAZ-3 (NBC) Huntington when the PBS stations were off the air or when the Cincinnati Reds were playing.
4) CBS via WJHL-11 Johnson City, TN (50 miles) or WBIR-10 Knoxville (100 miles)
5) WKYH (NBC)-57 Hazard, KY (30 Miles), a literal Mom and Pop operation who was the only source of local news.
6) WHIS (later WVVA)-6 Bluefield, WV (NBC) (100 miles) or WCYB-5 (NBC) Bristol, VA and WATE-6 (NBC and later ABC) Knoxville, TN (100 miles)
Later, network affiliates were confined to Bristol, Kingsport, Hazard (Now WYMT-CBS) and Lexington (WKYT-27 CBS-100 miles). As you can imagine, when conditions were right, the Co-Channel interference was a problem. WOWK and WLOS fought each other as did WVVA and WATE. WCYB-5 and WKPT-19 was constantly overwhelmed by WLWT-5 and WXIX-19 Cincinnati. WJHL-11 fought WHAS-11 Louisville. Once I remember when WJHL signed off WTVD Durham would break squelch.
