[Amps] 12V IM3

[Leigh Turner]

Yes same here in Adelaide South Australia Alek; rarely do I hear or see on
the Rx bandscope anybody's spurious IMD crud. We are indeed fortunate to be
living in relatively uncrowded geographic regions of low ham Tx density.

You all live in areas of high ham population.

Come to Western Australia where its hard enough hearing the the primary 
signals. You never hear any IMD products.

The bands are clean and uncrowded here. :-)
