Howard: Just checked wsprnet.org for W9YJ and no reports were under that call for the past 12 hours. Mark

Guess it had a leak and came back down. Sorry for the short flight.

What is up with the altitude or should I say the lack of reporting it? Mark

There was a mention of a tracking beacon independent of APRS. What is the frequency of that beacon? I am in Macomb, IL around 347 air miles away and would like to try and see if we can pull it in as w

That is a standard card they put on radiosondes. Had they a photo of the radiosonde info usually the person who releases it puts the location and date on the sonde itself. You no longer need to return

Interesting read but I have a question: From the position of not knowing your setup; what kind of regulator did you use? Was it designed for NH3? If not, do you think it might have been the source of

Great video and production and look forward to the next flight there Mike. Keep us posted. OK to share this post? Mark

Joe: Go find that MFJ in all of "your stuff" as it will work to decode your payload. Probably will need a copy of Hyperterm or something similar to view the data. Mark

Good thing no one ever caught me. I flew kites as a kid and I had a spool of string that held 600 feet of line. I would get the kite up and let it all out. If I had to go in and have dinner I would wr

Is this a floating with the currents type buoy or is it anchored?

Just keep it away from Virginia, IL.

I am the same way.

I believe so since it transmits on 144.390 and 144.340 thereabouts. There are openings in that area so possibly it made it to one of those. I know if it was close to me I would head out. Might be a ni

It is coming down. Harry, you gonna retrieve it?

Wow. Such a shock to lose Mike so soon. Enjoyed the GPSL he hosted and will miss him at future balloon events. My thoughts are with Mike's family and friends. Mark KA9SZX

I was wondering how it was being tracked as it lacked that information in the article. Mark
