Thanks guys! I hate to admit it but assembling a 14 minute clip took me about 4 hours with breaks in between. What a way to spend a Sunday morning?
I used several archived clips in the beginning as well as a hard wire directly to my recording software on the later clips starting with Oakland Center ZOA.
ect76 is correct - the final MP3 was exported from Audacity at a 16 kbps bitrate for the reasons mentioned.
