I read on the Maritime Radio Historical Society web site that they used
a Drake 2B as a cw monitor at the KPH coast station. The coast station
ops wanted to hear their cw as sent over the air.

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
