Okay, I just spent the entire morning dicking around with the old
streambox.
I think the streambox is working better here (new location) where the
electric is updated. With the same old box I no longer have the pulsing
hum from the wireless card.
I tied the VGA nut to my water pipes which are grounded and that got rid
of a lot of the base hum. It sounds more or less like when the VGA is
plugged in.
The only thing is that it still crackles a bunch and doesn't really pick
up all that much.
