John,
The 160/80 meter mod that improves IMD dynamic range requires replacing
a total of four parts in the T/R switching and one of the BP filters.
The mod would not be overly difficult for someone proficient with SMD
rework but I wouldn't recommend it for someone who isn't. To answer
your question, trying to break off the existing parts would most likely
damage the board. The areas are also pretty dense, so soldering iron
access is a bit tricky in a couple spots.

Can anyone who has done the 160/80 meter LP filter mod tell me if there are
parts now on the pads on the circuit board? If there are, did you just
break them off (then clean up the pads) or heat them and remove them?
