RE: Powermid Interference?

["Darryl Mattocks" <Darryl.Mattocks@xxxxxxx>]

Snap!  433Mhz version with the interference so bad with the PC on that we
now turn it off to get reliable results.  I thought it was me just losing
the plot as I can't really see why the interference should occur.

I too am moving to a hardwired solution and last week ordered all the kit
in
to do it.
