Re: Noisy Pi4 - particularly on 2m

Another solution, that I use here, is to buy a dc-dc voltage converter.  I have a 12v to 5v dc-dc converter with a usb connector on the 5v side.  I have Anderson power poles on the 12v side and I plug it into my 50a 12v power supply.  The DC-DC converter I have provides 3a of power to the PI which also helps with low voltage conditions on the pi.
