But you really don't *have* to replace the pots with fixed resistors. 
It's an extra step that doesn't contribute anything.

Order two small PCB-mounting trimmer pots - Earl has told you the values 
above - and mount them neatly on a small piece of perfboard as I 
described a few days ago. Then simply adjust the pots like Earl says... 
and the job is complete.

After all this recent good advice, I might go back and make sure my MP 
is absolutely optimized. Because the pots are still there, that will be 
much easier to do.


BTW, kudos to GW0GEI for his report on yesterday's inter-G contest.
