Model 718. Why is CW mode kaput?
There are a few possible reasons why your radio might not be transmitting in CW mode. One possibility is that the keyer chip has gone bad. Another possibility is that there is a problem with the power supply. If you have a multimeter, you can check the voltages to see if they are within specification. Finally, it's also possible that there is something wrong with the antenna connection. Make sure that everything is securely connected and that there are no loose wires. I hope this helps!
