>>   Yikes!  Looks like information is all over the
>>   place.  My browser is not letting me get any useful
>>   info from the  Blue Horizon site (or it just isn't
>>   there).  All I heard last night on 30 M was "N2XE MT
>>   MT"  and "N2XE ME MT" at random, but frequent
>>   intervals.

>>   I have been in email contact with John, N3XE and

>>   Thanks for the note, we really need an updated
>>   status for the balloon which is now somewhere over
>>   the Atlantic Ocean.  The website is
>>   www.projectbluehorizon.com and you can get a bunch
>>   of info there as well as report and telemetry you
>>   recieve.  The 30 meter beacon transimits at 10, 30
>>   and 50 minutes after the hour on 10.1465 +/- 500 Hz
>>   depending on the payload temperature.  If you could
>>   copy the beacon we would be eternally greatful since
>>   we are not getting it here in New York.  IF you
>>   could spread the word, even better!
>>
>>
>>
>>   Yes the telemetry callsign is N2XE
>>
>>   The format is
>>   Lat
>>   Long
>>   Altitude in meters (divided by 100)
>>   Battery voltage (Divide by 10)

>>   From John C. N2XE himself.  We ... from his
