Are you measuring this with the batteries completely removed or with the disconnect installed and switched off?

I will take a guess and say that it could be from the larger capacitors in the radio?

If it really bothered you you could go about it a few different ways, easiest would be to hook up the dvm where you can see it and start pulling fuses until it disappears.
