Is the 2 diode modification worth attempting?   I know it has been
covered here more than once just wanted to solicit the current thinking
on the matter ... thank you ... tom, N3LLL "

I performed the 2 diode mod and I would characterize the results as a night-and-day difference over stock.  It is extremely simple to perform and gets you probably about 90% of the desired result with less than 5% of the effort.  Give it a try, it is just as easy to undo if you are not satisfied.
