This is a small transistor receiver for the medium wave range made in Japan in the 1960s. The circuit is powered by 9 V and has an output power of 25mW.
This circuit is from the 1974 Motorola Unijunction Trigger Circuits for Gated Thyristor. The triac...
Found in old American documentation, this circuit can divide the frequency of a signal by 2 or 3...
This transceiver is also low power, but this time, it can generate signals in the 144 MHz band. In the...
