[RFI] 12v 5A linear power supply?

[Hare, Ed, W1RFI]

Yes, please do. ARRL will try to get one and measure its conducted emissions below 30 MHz.  These reports suggest that the device exceeds the limits.  If so, ARRL will file complaints with the FCC.

Hi Mike,

Can you share the specific part number or other other identifying details
of that very noisy (wall wart?) power supply?

That power supply Eric is looking for is to replace one that is one of the
noisiest power supplies in the industry and all over the country and it
probably doesn't draw much more than a half of an amp if it's the one I've
been finding.
