6W Morse-Code Transmitter 7Mhz Circuit

The vacuum tube is still alive and useful in some applications, as in this CW transmitter, The circuit was built in old-fashioned breadboard style on a wooden base. Old table radios are a good source of parts for this circuit. V3 is used as a ballast resistora 75- or 100- 5-W resistor could be substituted. LI is 15 turns of hookup wire on a form 2 long.

L2 is 7 turns of the same wire. L2 is wound over LI. Be careful as up to 160 V is present onYl and V2.
