Listening on receivers tuned to the three frequencies, they do occur 10 seconds apart, lowest to highest with a gap where presumably the 10500 Khz. broadcast would go.
A very significant observation. Sounds like Sam has a single transmitter with automatic QSY every 10 seconds.
Has anyone else noticed that you can hear Sam on both upper and lower sidebands, similar to an AM emission, but that there is no carrier in the center? (That is, the emission looks like double-sideband suppressed carrier, an unusual mode.) I missed it if someone else has already mentioned this.
