The key is the radio,

while many many will do crossband repeat, but few will be bi directional.  say you have 144 & 440  (yes I know the freqs are not valid this is just for example. OK balloon is at 90K feet and it hears a signal on 144 it re-transmits it on 440.

dozens will do that,  but few will do the reverse now with no changing at all,  it hears a signal on 440 and re-transmits it on 144.  for EBBE to work it needs to be able to go both ways.

Two balloons separated far enough apart that only they can see eachother and signal goes say from Wisconsin ground station to the Wisconsin Balloon to the Colorado balloon to the Colorado ground station and visa versa.

If the radio horizion for each balloon is say 400 miles, and they can talk to eachother, in theory two ground stations 1600 miles apart should be able to talk to eachother.

I'd never heard a thing about this event.  Could be of interest to many of the balloonatics on this GPSL list.

This meeting finishes up with its second and final day tomorrow, Saturday.

This could serve as a sort of testbed for seeing just how a virtual meeting could be expected to go, although there may well be video and sound "production values" which couldn't be equalled by a small group of people such as ours without such substantial and deep-pocketed institutional support (National Science Foundation -- my gosh!) that HamSCI seems to enjoy.

I'll be registering for tomorrow's session.

HamSCI Workshop 2020: The Auroral Connection | HamSCI

March 20-21, 2020
A Virtual Workshop Hosted by The University of Scranton

Come join HamSCI at its third annual workshop! Due to restrictions caused by the COVID-19 Coronavirus, this year's workshop will he held as a virtual, eletronic workshop.  The meeting will take place March 20-21, 2020 using Zoom Webinar Services hosted by The University of Scranton in Scranton, PA . The primary objective of the HamSCI workshop is to bring together the amateur radio community and professional scientists. The theme of the 2020 HamSCI Workshop is "The Auroral Connection: How does the aurora affect amateur radio, and what can we learn about the aurora from radio techniques?" Invited speakers include Dr. Elizabeth MacDonald, NASA Scientist and founder of AurorasaurusDr. James LaBelle, Dartmouth Space Scientist and expert on radio aurora, and Dave Hallidy K2DH, an expert in ham radio auroral communication.

This workshop will also serve as a team meeting for the HamSCI Personal Space Weather Station project, an NSF-funded project to develop a citizen science instrument for studying space weather from your backyard. The PSWS is led by the University of Scranton, and includes participation from TAPRCase Western Reserve University/W8EDU, the University of Alabama, the New Jersey Institute of Technology CSTRMIT Haystack ObservatoryDartmouth College, and the ham radio community at large.

I have been planning on doing a balloon this year but if I have to do it here in Phoenix I don't think that will happen.  110+ is just too hot to hike around the desert.

I'm still hoping that things will be settled by July and I can get out of here for a while :)

I just proposed that same concept to the Dayton Hamvention folks. If it comes to that, we can use Zoom, Webex, Microsoft Teams or any other teleconferencing software to accomplish that. We could even do balloons launches at the same time but at our own locations and link the launch videos by a single site...Facebook Live?

Of course, at this date, it's hard to say whether various travel and gathering restrictions will be lifted in the next four months - I'm sure we all hope so.

I'm not sure how far in advance attendees will have to make commitments that will be hard to get out of.  I assume we'd have to fish or cut bait by around June 1st.  If your group would need an earlier decision, let me know.

So far, there is nothing that would prevent us from going forward.  However, I have indirectly heard that the University of Nebraska system is doing some (contingency?) planning for teaching summer classes online only.  Our Friday session is planned to be at Nebraska's Omaha campus - if that is closed, we'd have to relocate.

Of course, at this date, it's hard to say whether various travel and gathering restrictions will be lifted in the next four months - I'm sure we all hope so.

I'm not sure how far in advance attendees will have to make commitments that will be hard to get out of.  I assume we'd have to fish or cut bait by around June 1st.  If your group would need an earlier decision, let me know.

Re: High altitude floater

Thanks for the kind words.  I got sucked into the world of satellites (professionally) and haven’t had a chance to play much with balloons.

 

But a few comments.  The original author’s intent sounded like something very different from mine, and something that I actually haven’t heard of.

 

My balloon that flew for over 2 years and finally broke the record that NASA held with the ghost balloon program, was extremely light.

 

The payload was custom built and weighed ~9grams

Ron’s company made the balloon (envelope) and it was made from a special material that was used in the food industry for wrapping sushi 😊

My balloon flew on H2, not HE

As a result for 767 days it was  at approx. 46000 ft and was considered a Super Pressure balloon (fully sealed envelope)

 

The primary tricks are  - you have to float at above 41000 to stay away from airplanes

You have to use a material that won’t *leak* your lifting gas

Your payload has to be extremely light

And in my case I flew a solar only balloon, it didn’t have a heavy battery instead it used a super capacitor and solar panels

For radio(s) you have to use something that can be tracked world wide (APRS isn’t that btw).

So my balloon used *both* APRS for when it was in coverage, and WSPR (yes on 20mtrs) for full world coverage (it has 2 antennas a ½ wave on 2mtrs and a ½ wave on 20mts

Of the first 2 years, it was heard and tracked via telemetry every day but 3.  There was a gap at the end as over time it developed an intermittent problem.

 

Here is the last version of a Presentation that used with a few local Ham Radio clubs before I left Atlanta and moved to Utah.

 

I do have some plans upcoming for a few more launches and the second board that is referenced in that presentation will likely be available after further testing (the company I work for hired the developer – but we’ve been completely consumed working on low cost, commercial satellites 😊 )…

I can answer questions, but my responses will likely be delayed so bear with me,

Ps. The balloon flew under the call of K4JCW, because my call was on a sister balloon that was still up when we launched the record setting one.

As Howard pointed out, Alan holds the record.  The last account I have seen is HIRF-6 was up for 767 days and 35 laps.  I'm sure it went farther than that.  You can see some of the info here: http://www.scientificballoonsolutions.com/news/

 

This is Ron Meadows company.  He made the balloons Alan used.

Stan,

 

Alan Adamson has had multiple long duration flights. I believe his e-mail is:   adamson_alan@...

 

Bill Brown wb8elk@... is experienced in all types of balloon flights including extended duration floaters

 

Ron Meadows K6RPT is someone who has flown extended flights and manufactured balloon envelopes.  See www.cnsp-inc.com

I am working on launching several long term floaters with hopefully multiple passes around the earth I have several persons saying this has been done with up to 7 passes although I have not found data to support this. If any one would have information on any of these flights I would appreciate receiving the information on those flights. I will be using a APRS LIGHT W  tracker with  a usb battery and solar panel to charge it on the first flight with the possibility of adding a cross band repeater Later if I can prove  that we can keep them up for sufficient period of time. The electronics is the easy part the Balloon is the difficult part. I am looking at making my own balloon using stratofilm 430 ,If any one has done this I would appreciate any information they have and what there experience was. I would also appreciate any anyone offering information on a project of this type.
Thanks Stan Siems WB0EMJ

Let me know when you guys have a floater up. We are now teaching from home and I teach introduction to programming. I think using a floater or two in my curriculum would be a nice discussion point. Please let us know when you are up and flying!! Thanks!!
