Indicated for scanning circuit applications, we found this generator in a Radio Electronics from the 80s. The components used are still common today.
This circuit can also operate with SW and even VHF signals up to 150 MHz. The circuit can be...
This integrating circuit multiplies the time that can be obtained with a 555 timer. We find it in...
This transmitter for the 7 MHz range, as we can assume by the number of turns of the coil, since the...
