When I see charts like this I am astounded by how little power most of the stations were operating with…..many eventually prominent stations wit 50 or 100 watts. I guess there was way less industrial interference back then.

quite right, Steven. In fact, there were very few daytimers back in 1936 as the AM frequencies hadn’t been packed yet – that would occur starting after WW II. There were, however, “share-timers” on some frequencies. Note a number of these in Vancouver BC. Some of these low powered signals carried incredible distances. KXA 770 with it’s incredible salt-water grounding system on the downtown Seattle waterfront was heard many times overseas in the 1940’s by US personnel stationed throughout the Pacific during it’s overnight 4-hour broadcasts. This using 500 watts!!

Seattle-Tacoma had 10 radio stations. I will bet you that each one of them ran Christian programming on Sunday, some also on weekdays, regardless of their regular format.

no doubt Jason. Broadcasting live church services Sunday morning as a freebie was often done in lieu of the FCC minimum airing of local public affairs requirement. The religious shows that were a part of the weekday ‘block programming’ were probably paid syndicated shows as is the case today.
