Is it possible to calculate internet radio CAP usage. My package comes with 2 gig a month, any usage after that gets billed separately. My DSP Z7 doesn't come with a receiver, the amp is connected to the internet via network cable. My previous amp had a tuner and i would play the radio during the day. If i played internet radio, i would like to calculate the cost if i had to use it. I know my Skype service uses 180 meg per hour. Hope this makes sense.
