I recently purchased FT-1000MP Mark V Field, Serial no. 2F05xxxx. I was told that the key click problem for this set had been fixed by a production change at the factory. Is the NB mod for the Field exactly the same as that posted by W8JI for the 200 w Mark V? What other cw mods would be advisable? Any help would be greatly appreciated. 73 Paul W5DM
