OK, so the syndicated Tech Guy has two airings each weekend, a three hour show on Saturdays and another three hour show on Sundays. (The Wikipedia page for The Tech Guy only talks about one airing, but Wikipedia may not be that reliable.)
On most iHeart talk stations that carry The Tech Guy, it usually airs only once. (Some larger market iHeart stations, such as WOR NYC and WRKO Boston, don't air it, since the weekend schedule is non-stop infomercials.)
In smaller markets I do see The Tech Guy scheduled for both Saturday and Sunday. But I thought they were just double running the same show. In those small markets, they often double run the other weekend Premiere Network shows, such as Handel on The Law and At Home with Gary Sullivan, once on Saturday, once on Sunday, since they don't have much other programming to air.
