via HACKADAY: Using a Cheap Handheld Radio As A Morse Transceiver

Both grizzled hams and potential future amateur radio operators are well-served by the market these days. Powerful and capable UHF and VHF handheld transceivers can now be had for well under $100, something unimaginable as recently as 20 years ago. Of course, a major part of the amateur radio scene used to be Morse code. Not to worry though, you can do that with a handheld, too!

The setup is simple but effective. A Morse code training unit generates tones in response to input from a Morse keyer. This audio is passed into the headset port of a Baofeng handheld transmitter. A toggle switch is wired up to the Push-To-Transmit circuit of the Baofeng to trigger transmission when required.

It’s a little different from the more typical constant-wave transmission methods that are so seldom used nowadays, but it gets the job done. Morse code has always been appreciated in situations where voice transmission is difficult due to low bandwidth or interference, and now it’s easy for new hams to give it a try.
