Hi John,
I used a TS120 when I took a lightning strike and power surge on my TS520. 
I agree it is a nice little radio.  I don't remember how to use it on CW but 
it didn't have a CW filter in it but the I-F shift made it so tight that I 
could use it in place of a filter.  Good luck with that one.
