Just statrted, someone tuning up ... can hear program audio starting up now with the 400 Hz tone still on freqeuncy

02:04z

Tone shifted in frequency slightly, a little bit of waver, as if the tone oscillator is affected by sags in the AC line

Can still hear occasional weak musical program under the tone, sounds like another station.

02:08 Tone was briefly interrupted ... I hope this results in a fine program to follow! More variation in tone. Someone is tuning up their xmtr on-the-air ...

02:19z - Tone off (at last)
