Re: IR with Comfort

["nick broughton" <mail@xxxxxxx>]

Ian

How have you implemented the feedback protection?  Did Nigel help with the
circuit?  Is it radically different or just a 'few' extra components?

Having finally sorted RF distribution I know need IR distribution.  I was
about to order some boards from you but as you know, feedback protection is
something I would like in this system.

I'm keen to know more, keep us informed.

Regards

Nick
