We are two artists interested in capturing a high(ish) quality recording of the CMB. We have just begun our first wave of research into the topic and are hoping for a little direction. Is it even possible to acquire a clean recording of the CMB without the use of expensive and inaccessible telescope arrays? Where might we find affordable hardware that can receive VHF waves, and would they be able to hear the CMB through the background noise of civilization?
We've come to the conclusion that sending a weather ballon equipped with an antenna and some recording equipment into the stratosphere would be neat but we aren't quite sure this is the most direct, or inexpensive, way to capture the CMB.
Any help would be much appreciated.
