Dan, VO1MX, reports nothing heard so far in Newfoundland. Not necessarily bad news, since the balloon would have been almost 200 miles from Dan when he started listening and he reported S7-8 noise on the frequency. So it could be there and simply too weak for him to hear.
If anyone in Newfoundland is reading this right now, please listen to 29.499 Mhz right now and see if you can hear the beacon! Even if it is there right now, it will be moving very fast and the chance to hear it will be quickly over.
Thanks to all who have written and asked about it... We remain hopeful and welcome any reports.
