Here you go.
MFJs JimHandy Morse Code / CW Interface plugs into your 144/440 MHz handheld and converts it into a modulated CW transceiver -- all you need to do is plug in your key. Get your ham buddies together on-the-air and enjoy some fantastic CW fun!
Run a little morse code practice on your repeater. Start your own FM CW net. Have fun and upgrade! A transmit/receive switch automatically switches your HT to transmit when you send CW and returns you to receive when you stop keying. The MFJ-552 has a built-in speaker, volume control and great sounding true sinewave sidetone -- NO harsh keyclicks!
The MFJ-552 measures 4W x 1 1/4H x 3 3/4D inches. The MFJ-522 uses one 9V battery (not included).

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
