Hello All,

Let’s start thinking about another balloon launch date and the pre-flight date.
I have another tracker built. It weighs in at 315 grams (11.1 oz). I am using
alkaline batteries now but will change to lithium for the flight and that
should reduce the battery weight. It is setup to use two suspension lines. Any
open dates in September? Saturdays are best for me.

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!

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...
