As a former employee of WKTV (many, many, years ago) I have a little insight on this subject. If you are high atop Smith Hill, you'll see WKTV's original tower from their days of being on channel 13 is still there behind the building. On that tower you will see many antennas for both receiving and transmitting. Some have not been used in many years . Some are still active. Some of them I don't think anyone has any idea what they are for.
WKTV used to be co-owned by Harron Cable and their head end was located in the WKTV building. Harron used some of these antennas to recieve stations off the air, such as channels 3, 5, 9, & 24 in Syracuse and ocassionally some Albany stations. WUTR sent their signal across the street via an underground cable straight from their master control switcher. Now one of these antennas may have been used, at one time, to receive CKWS off air. It is possible. However, I believe CKWS was received thru Eastern Microwave same as WNEW, WPIX, & WOR. The people that would know about this for sure, I am afraid, are no longer among us. The people that I did work with, that are still with us, probably wouldn't know for sure and would be guessing about receiving CKWS off air back in the 50's, 60's and early 70's.
And by the way, the slogan "broadcasting high atop Smith Hill" had totally different meanings at WKTV and WUTR.
