[TheList] Smart Power Meters

Sun Jun 9 08:14:30 AEST 2019

Very interesting reading.

I have a Mk-7A installed in 2011 which, if I read the datasheet 
correctly, can do 2G, 3G or 4G.

The interesting bit for me is that I've been trying to trace some RFI 
which is very similar to what a Vodafone phone can sometimes cause in a 
bad amplifier circuit. Now that I know the Power Meter uses Vodafone I 
now have the cause.
