The TX range are designed for lower temperatures (than the standard TA range) - but they are still primarily a Latex balloon - just a different set of additives gives the their low

Wow!! Very impressive, Mike!! Love to see these sorts of videos. Great work over there in the NE. -Jeff N6BA

I was wondering if there's any HAB clubs/organizations in Oklahoma or Missouri. I participated in some flights with PARK a few years ago and chase crew with EOSS. I am in Civil Air Patrol and would

Great video and production and look forward to the next flight there Mike. Keep us posted. OK to share this post? Mark -- Mark Garrett Chief Engineer Tri States Public Radio WIUM Macomb, IL WIUW

Gang, I realize I was remiss in sending a final follow-up of this flight. The Alpha Cubesat team put together a fantastic 7 minute video discussing their project, and our flight last October.  

Bill was working something out. My understanding is were still planning to go to the Spaceport in Indiana.

I didn't see a response to this. Are plans being made for this year's GPSL? Jerry

It's been a LONG time. I da oldem days we always thought that the difference in "Lift" at day vs night was about 10%. In other words at sundown you loose about

Fine with me! Shane Wilson, N4XWC

A Japanese TV company (One by One) have approached me** to help get permission to show the Habitat tracker screens on a TV program.  I can't see a problem with the screens per-se (other than the

WOW!

Habhub grabs the data for the entire earth 4 times a day. That has a 1 degree resolution. Then they interpolate between time, altitude, long, and lat to come up with the wind at the current balloon

I tried that one, it seems to work, almost seems too simple! I guess from the launch location, it is smart enough to know what sonde data to grab?

I find this on-line prediction to be somewhat reasonable when it comes to Radiosondes. http://predict.habhub.org/#!/uuid=a2b6cf262e4662d11c3ebd58c603d500bac397fc -- Mark Garrett Tri States Public

Looks like mine (https://s3research.com/tools/flightpredictor/) isn't working right now. It looks like the weather file has a change that is breaking it. I can fix it if anyone wants to use it. At

What now days is the best flight prediction page calculator now days? joe WB9SBD

Hank, I agree, and thanks for that link. At my age, and while I was composing my previous email in this thread, it occurred to me that I ought to do a search for YagiCad's author by his name, but by

Back in my day, you had to lay on the lawn with your yagi sweeping the sky for the signal, and then use RDF techniques to chase down the payload. (Do I sound like one of those old timer ham radio guys
