https://stream.echo6.co/videos/watch/51dc62f9-f32b-4c56-ac67-9ed49a0491ed Single letter Morse generator using two common CMOS ICs. Useful for foxhunt beacons etc. Change letter by inserting diodes on different pins of 4017 decade counter. Note the clock capacitor should be 2.2n not 1n as shown in the diagram (the sending with 1n would be fast).
