Hi RA,
At the ripe old age of 21 I started out at CFPA radio Thunder Bay. 1230 on the dial, 1000 watts day 250 watts night. I had to dial up and down the transmitter at sunset to protect some other rinckey-dinkey station somewhere in the northern US of A. Yes, it looked like a phone dial. Missed it a few times and old man Parker was kind enough not to chew me out about it. Seems even back then, the DOC checked every station's power output. 250 watts night, lucky we hit the city limits with that! Complete with a limiter and compressor on the board output.
