A schedule board. Here are the frequency for each transmitter and every hour. So, at 4 am began the P1 and P2 (8/1&8/2) in combined (500Kw),  at 9520Mhz, antenna group "D", the 9Mhz. one. Below, at the same time began the P5 (MRC) at 9660, group C, south direction and low azimuth (last "B" stands for "L" (low) in spanish). The little numbers with the sign "-" indicated us how many minutes we had to cut the transmitter in order to prepare the next. Almost all was manual.
