?
I don't use a DC power pack to power the DR4018. I have a 12v 3a? AC to DC wall wart power supply. The buzzing starts when the DR5000 track power is turned on even without the wall wart plugged in to an electrical outlet. I installed a 2nd brand new DR4018 on a different section of my layout yesterday with 3 brand new Kato #6 turnouts. Wired the same as the 1st DR4018 and all 3 turnouts buzz also when track power is applied. I have a Digitrax DS64 hooked to 4 Kato #6 turnouts powered with? a Digitrax PS14 wall wart and they do not buzz.
With that said then you have a 60hz. humm' from your DC power pack. the cheapest way to fix it is to buy a wall wart 12 VDC power supply. Amazon, Ebay or some local store that sells electronics,
