Jim, It seems that MCW does not have the advantages of true CW. Does anyone just attach a key to the PTT terminals? Rick

Modulating an FM transmitter (like the 60R) by feeding tones into the mic jack is called MCW (Modulated CW). It's the same as whistling CW into the mic (if you're good at that!). ? If your HT is set for Wide modulation (the norm), the bandwidth will be the same as voice, +/- 5 kHz, for a 10 kHz total bandwidth. ? Many ham clubs provide CW practice this way (tones, not whistling!)?on a local repeater. ? True CW is turning an unmodulated carrier on and off for the CW characters. To receive this properly, you need a receiver with a BFO (Beat Frequency Oscillator) to generate a tone from the on/off carrier. ? ? --jim KJ3P
