Sorry to hear abt BBC on 198 QRT. When I was a young man after WWII we often
listened to this station in the Ruhr area to practice English.
And our first exact frequency generator was baseg on Droitwich. 6SJ7 or
similar as amplifier followed by 6SL7 or 6SN7 as square-wave generator
200kHz. The harmonics were calibrating points up to many MHz. The equipment
was built in a small aluminum bread bin. And we were angry, when the
frequency was shifted to 198kHz.
