Twaddle. The noise you hear between TV stations or an old wireless is Resistive Thermal Noise. Nothing to do with CMBR which is in the 160 to 280GHz range - Wiki - which is way beyond the range of any domestic TV or radio.

The cosmic microwave background blankets the universe and is responsible for a sizeable amount of static on your television set--well, before the days of cable. Turn your television to an "in between" channel, and part of the static you'll see is the afterglow of the big bang.
