[Icom] The saga of the 761

Thu, 1 May 2003 15:22:50 +0800

Hi Bill,

I just couldn't let this pass without saying  Thanks for putting this tale 
of persistent efforts up for all to see. Well done.

If ever there was a message about the need for persistence  in fault 
finding in worth while gear this was it.

I would hate to contemplate though the cost if your time was to be 
charged out at professional rates :-)...

Enjoy the fruit of your labours.

supply at present...)
