The WTFDA was around even back in the '60s. DXers maintained contact with others via the Worldwide TV FM DX Association and the National Radio Club (NRC). They would routinely monitor analog channel 2 from May to August (or 3 if 2 was occupied) for the rolling bars that usually meant Eskip. Some called other DXers to remind them that the FM or VHF TV bands were open for DX. Some were hams and monitored 6 meters AND analog TV. For tropo events, they would look at the upcoming weather forecasts for temperature inversions, and often had contact with nearby DXers in other states if the tropo event was large. William Hepburn's charts (DXinfocentre) are the best source for finding out about Tropo now.
Here's an example from August 1987 of the VUD...1987 was a great year for E skip DX.
Oh and BTW, the late Jeff Kadet (K1MOD) in Illinois was one of the greatest TV DXers of all time. He caught 1800 TV stations I think? Mostly tropo of course, but tons of E-skip too. He had a multitude of antennas and could see 750w to 1KW UHF translators from 600 miles away if the opening was strong enough.
