[RFI] "Inverter Technology" microwave ovens

[Dave Hachadorian]

That's the reply I was looking for.  I think it's the same oven 
I'm looking at at Walmart.  Many thanks Chas!

Thanks for all the other replies too, especially the one that 
suggested I don't need an oven because I live in Yuma!

73, and happy holidays!

Mornin Dave; I purchased a Panasonic Microwave from Walmart which
advertised itself as having Inverter Technology. It is the 1250 
watt
model, however, I forget the exact model number. The important 
issue for
me was RFI and I am pleased to report I hear nothing from it 
while
powered up and cooking or just in standby (not cooking but 
plugged into
a wall outlet). It is clean as a whistle. I pay attention to home
generated noise and probably have 60 or 70 pounds of ferrite 
around my
home. This required no additional "fixes".  This was a very 
pleasant
surprise given the state of consumer electronics today.

Best, Chas W5PG
