The two circuits shown show how to obtain an SSB / CW control for receiving this signal top at a common receiver. The circuits were found in an old American manual from the 80's.
This power supply can sources currents up to 22 A to a load. Voltage is 12 V and the transistor...
For signals up to about 500 kHz modulated in amplitude and transmitted by the power network, the...
This circuit was obtained in a European documentation of the 80's. The circuit uses common...
