     There are various sorts of monitors you can use. For 
instance the old Bud code practice oscillator can be hooked 
up to be triggered by strong RF. I think many of the old 
ARRL handbooks had articles for building similar dual 
purpose oscillators.
     However, I used to monitor off my receiver. There was 
enough leakage through the antenna relay to hear it at about 
the same level as the received signal. My rig at the time 
was a modified BC-779, and a modified BC-375E driven by a 
home brew exciter. I worked a lot of CW and this arrangement 
worked well. I just left the REC-Send switch on the receiver 
on REC so that it was not muted by the muting relay.  I am 
now using a set of Drake 4B line twins. The transmitter has 
a side tone oscillator but I still prefer to unmute the 
receiver and listen on that.  The side tone has an advantage 
where you want to send and receive on fairly widely 
different frequencies but that is unusual for amateur 
practice.
