Hello Rod, excellent information in your response about FT1000MP key
clicks. I think that a copy of your post to the  
1000mp-list@jehosophat.com   FT1000MP Reflector would also be an excellent
place for your comments. Would you mind putting it there?  I have already
put my earlier message there. I would not mind putting it there with your
permission if you wish me to. 

Thanks for taking the time to post such specifice information that we all
look for on these reflectors. Its info like yours that we concider the
gems...... hi hi
