[Kenwood] SM-220 question

[ad6zu at comcast.net]

Hello Ron,
IMO the best use for the SM-220  (hopefully you have the panadapter installed) is to use it to visually "see" the radio spectrum around your tuned frequency.  Just hook up the 8.83MHz IF out from your Kenwood tranceiver to the IF in on the SM-220 and look at the stations as you tune across the dial.  I've also hooked up the SM-220 to other rigs that don't have the IF out such as the TS-450.  You just need to tap in to the 8.83MHz signal.

I have a nice SM-220 lurking back in the closet.   I think it's time for it to get out and on my desk.   My problem is I know little about the signal monitor.    

Let's start with trapezoid.   WIth it all hooked up, I thought maybe you could monitor you xcvr as well as final trapezoids.    

1.  However, I see that if you don't use your final, it somehow has a trapezoid that is "meaningless"  I'm not sure how this all works, but is in fact the trapezoid of your xcvr only really meaningless?
If so, It wouldn't be of any use to me displaying it.  The final trapezoid yes; the xcvr trapezoid no.  

2.  I can just add the two tone connection to the mike on my xcvr, and see those patterns.

3.  Not sure of control setting, but there is another way to get voice patterns as you talk----lot's of squiggly lines jumping up and down.   

The reason I'm asking this, is because I think we can do some things with it being in place, and no changes added in.  Just park it on the desk, and use it without adding anything.
