Hi Walter, I wonder if the shf stations used modulated cw? Looks like they used Gunn oscillators, which could have drifted a GHZ doring the transmission At that frequency, they were using an incandescent lamp... :-)Actually, the transmitter block diagram at the Web page cited in the original post shows a really sophisticated PLL system to stabilize the oscillator to the accuracy of the 5MHz source.
