Ok thanks. What's the payload weight and our target neck lift?

I have just been using an ascent rate of 4 mps and an average descent rate of
7 mps. Those were the rates we calculated before.
I think we were figuring a 300 grams balloon.

I don't recall what the balloon size was. I can get a 200g or a 300g pretty
cheaply. What are you using in your model?

Unfortunately similar to the response to previous suggestions.
I have tracker and video payloads still ready to go.
If you run simulations for the next couple of weeks they are quite variable.
I am available on about half of the weekends through the end of Spring.
If there us a good time for you, Dan, or may be a couple choices, post and
see if we can get things going!

Hello Guys,
I have my T3-mini/SRB MX145/ADS-GM2 APRS package ready along with the
original beacon only package. It has been ready since last year.
Are we ready to plan another balloon launch? The weather is getting nice.
If we can have an equipment dry run day followed by a launch day maybe on
separate weekends, I think we will be set.
Last year we attempted on 4/4/2015, perhaps we can target a May date.

Dan,
I just need to charge the cameras. It can be ready to fly tomorrow.
Why a simulated file? Wouldn't it be good to just assemble the tracker and
test it?
It would be good to have actual elevation change. Maybe up the 18 toward
Big Bear/Running Springs? The road gives fairly good coverage of the San
Bernardino area, and climbs up to about 7,000'. Any other routes that
might work?
Another option is to do it like an old fashioned mobile fox hunt. Take the
tracker to an undisclosed location, and see if we can find it. Maybe a
hill top?
Using the tracker and a mobile antenna should give a fairly good radius
for the signal. Move to a different frequency for the test to see how well
we can track directly.

Hi Dave,
How is the photography payload? I am very close to completing the
T3-mini/SRB MX145/ADS-GM2 APRS package. I just tuned the dipole this
weekend. I will send full details once completed.
Are we still good for a dry run with a simulated flight profile? I will
generate a simulated GPS data file and run that into the tracker. The
tracker will be car mounted but we can verify everyone’s gear before the
real launch because they will have to find me!
73, Dan

The winds and winds aloft are somewhat unusual for this time of year. Must
be El Nino or climate change.
But the predictions are actually running favorable to a launch from either
our primary spot, landing in Johnson Valley, or from Lucerne Dry Lake and
landing in the Newberry Springs area.
We may not have to wait for fall...
