This converter for WWV time reference station signals was found at Popular Electronics. The 15 MHz signals are now received on a medium wave radio at 1 MHz.
This circuit was found in old documentation. PUTs are uncommon components today. The circuit...
This circuit was obtained in a 1991 Electronics Handbook. The publication no longer exists, but...
This crystal oscillator generates a 20 MHz signal. Equivalent transistors such as BF494 and 2N2222...
