good question ...thanks

can I think about that ...........

I'd like to just say ........all who heard it [30 plus ] could tell with in a few minutes ....

but you want more than that .....

I'm off to see another victim today ...so we will see if that throws  something up.

Just an observation .......the people who seem to be shouting loudest[ in general]that it can't work are precisely those people who have not heard  it.

I consider their views to be  inconsequential....I do how ever value the views of all and I mean all who have taken the time and effort to listen to the unit. But do I care ...actually yes  all those wallies that have spouted off  without the slightest experience should look very closely at the own motives ...as its certainly not the advancement of the understanding how this may or may not work. There appears to be a malicious element that want to denigrate ideas or equipment, that fall out side there cosy closed world.  It's no surprise that none of the naysayers have even bother to pm to see if I can bring the unit over.......speaks volumes.

effem......very well put
