Wait just one second .....
I was curious how NIST Radio Station WWV was going to handle the leap second at 12/31/2005 23:59:60 UTC So I tuned in and recorded this file for posterity.
This was recorded from about 23:58:50 to about 00:00:40 on 10Mhz using my Yaesu 757GX connected to a 80 Meter Dipole. Audio was captured with a laptop running Debian and recording in OGG format. Since the version of SOX I'm running didn't support MP3 output I had to first convert to WAV and then use LAME to convert to MP3 format. True, some conversion loss, but considering propagation fades, atmospheric noise and man-made adjacent channel noise .. What the hell do you want!!
If you're getting ready to count the "ticks" some notes: WWV omits the 29th and 59th second ticks. From what I heard it seems like there is an extra one second delay between the 58th tick and the 00 second mark at 00:00:00 1/1/2006 UTC

Cool, thanks! That's exactly what I would've been listening to had I not been on the road at that hour, so I appreciate the fact that you captured it. You're right about the extra second of silence at 23:59:60 UTC. Interestingly, the conversions you put the audio through seem to have sped it up some, as a side effect. If you count the ticks while watching the second hand on a clock, you'll start to notice the difference in speed after about half a minute.
