I guess people were reading more into my "plain old oscilloscope" use in place of the 
SM220/230.  I was refering to the simple time domain type of signal display for 
viewing the waveform.  Currently I have two SM-220's connected to my R-820 receiver.  
The R-820 is triple conversion unlike the TS-820 which is only dual conversion.  One 
of my SM-220's has the BS-8 panadapter inside and is used on the 8.83 IF for spectrum 
display near the operating frequency.  The other SM-220 does not have the BS-8 and is 
used simply for it's time domain function just like a simple oscilloscope.  This 
second unit is connected to the 50KHz IF out on the R-820.  This allows me to view the 
received signals waveform.   For AM signals it would be the RF envelope that is viewed 
or just a simple keyed sine wave for CW signals.  You get the idea.

So when I was stating that an o-scope could be used in place of the SM-220 it was only 
for this time-domian signal observation.  Still it sure does look alot nicer having 
both Kenwood scopes running at once with the R-820.  Also quite an equipment line 
(Kenwood 8-line) when transceived with the TS-820.
