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
