One of first things taught when I first began running a board (taught by Darryl Dahmer no less, in his Kitchener CKKW life) was taking the hourly readings. Our AM-er at 1320 and later 1090 had a strange looking pattern and thus something like 8 towers had to be read. Using the same telephone dial someone else mentioned we had to cycle through a dozen numbers and write them down...in theory, every hour near the top of the hour. Most often they were done once a shift by more 'experienced' ops. And twice a day the pattern change...what a rigmarole. No single button to push. (We were warned it could blow up the transmitter!) Shut off the signal...dial 3 or 4 numbers to change to night or day pattern....then turn the signal back on. Then do readings again and compare with previous one to indicate which towers were on or off or at lower power.
All these daily sheets we were told, were sent to Ottawa where some department read thru them to verify that we were following regulations. Several years later, during a building cleanout, boxes and boxes of these readings sheets were discovered at the back of a storage room. Ottawa, indeed. I recall several occasions  when going in to op a Sunday morning show, the pattern was still on daytime and had been all night. The previous evening's op (weekend=part-timer / newbie, of course] had not done it properly. We never lost our license that I know of.

regarding the two early FMs in K-W.
Although the CKCR FM station took the air a bit before CFCA FM #1, it was simply a repeater for the CKCR AM and remained so for many years...... (CKCR became CHYM in the early 60s).....
CFCA FM #1 went on air with no AM sidekick and although only broadcasting a few hours a day, did all original programming at 106.1 beginning April 26 1949. The studios were in what was called the Medical Arts Building and the 3,000 watt transmitter was on a large hill west of Kitchener near Baden...among staff names were Fred Russell, John Becker, Gordon Jackson, Bob Munn, Norma Armitage and announcers Alan Watts, Hal Wardell, Len Starmer and Ken Summerville.....on the first broadcast, CBC heavyweights John Fisher and Lorne Green were guest presenters........
Programming was heavy on local music talent of course. But it was a chicken and egg thing: CFCA had been started by Electrohome and the Pollock family in order to help sell FM-capable radio receivers which Electrohome was manufacturing. With very few FM broadcasters in the late 1940s, there was little market for their sets. So when CFCA FM#1 goes on you have few people able to hear it. In an attempt to help sell the station's programming it was arranged to install receivers in some of city's trolley buses. Riders would hear the programming, hopefully enjoy it and line up to buy FM receivers.....after a bit over 2 years it was evident that FM was a stillborn baby in those days and they pulled the plug. The call letters were reflective of Carl A. Pollock's first two initials, his father had started Electrohome but Carl was now in charge. 
​Of course those are very famous calls in radio history. In Toronto an extremely early AM station (run by Toronto Star) used them. On CFCA AM in 1923 Norm Albert did the first-ever hockey play-by-play, a few days before some fellow named Hewitt started becoming famous. That CFCA ended around 1933.
​So even though it wasn't always in Kitchener that set of c
