Thing is any other audio oscillator with a fine waveform takes a while to start and to stop and won't follow high speed keying well and the sawtooth is has as fast a rise and fall as the RF output. Cleaning with a low pass filter adds delay too. I suppose one could rig a continuously running sine wave oscillator and switch the audio from it on and off and keep up. But that's more complicated and its hard to get rid of the back wave. I prefer to monitor my sig real time with another receiver. Also lets me know what the xmtr is sounding like. Having kept every rig I've had since '61, there's several to choose from. Mostly use the HQ180 and a large old speaker right at ear level. RF & AF gain adjusted down of course but still loud enough to hear with the cans over my ears. I've never found a built in monitor that I liked..........73, WA4TT |
