This stops right now!  You will not badger anyone who offers 
data and support on this reflector as you have done so time and 
time again.  

If you have technical PROOF that contradicts the data offered, 
post it on you web site and offer a link to it.  Otherwise, 
stop badgering people.   

It is great to see Tom back here after many years and many 
subscribers hope he keeps coming back.  You will not turn the 
amps list into your personal vehicle to beat up on W8JI and 
W0ID.  Your constant "League Fatigue" and "recognized experts" 
tirades have outlived their welcome.   

Keep things civil, professional and technical.
