AD7DB is planning a day trip to CM94 near Vandenberg AFB California.
This will be on Saturday June 16 2018. Mark your calendar!
I am planning to work passes from 1700z to 2300z timeframe, on SO-50, AO-91
and AO-92.
More details will be posted on Twitter @????? as the time approaches.
If you need this grid, I will try to be there for you.

John,
Good suggestion, but "unfortunately" I already run it as an administrator.
Bad security practice, but as you say, it can eliminate odd problems.
The Meltdown/Spectre patch has caused a noticeable performance hit on my
machine, even though it is very capable. I am wondering if it may be
causing a timing problem? Fortunately the problem only occurs every 2-3
days, but is annoying for unattended operation. SatPC32/Labjack have been
running flawlessly for literally years.

Hi OMs,
We are planning two tests for UHF of DSLWP-B, from 31 May 16:00 UTC to 31
May 18:00 UTC, and from 1 Jun 02:00 UTC to 1 Jun 04:00 UTC.
We will change the mode of the transmitters to 250 bps GMSK and JT4G on
435.4 MHz (GMSK every 5 min, JT4G every 10 min, JT4G has higher priority),
and 250 bps GMSK on 436.4 MHz (every 5 min). Corresponding demod grcs should
be used.
Some more tests are planned on Jun 3, and detailed time TBD.
The temperature of onboard batteries is a little higher than expected,
that's why UHF is not always on.
Tracking file updates can be found on: https://github.com/bg2bhc/dslwp_doc
or http://lilacsat.hit.edu.cn/tle/program_tracking_dslwp-b.txt

Hello?WEI Mingchuan,
congratulations for? your mission and many thanks for DSLW-B info.
Can any gnuradio Guru write a short guide on how to set parameters on
gnuradio Live CD?Please, not interested in how to download the .iso file but
wich parameters set and in which way in gnuradio window when the Live Cd is
up and running.
Thanks in advance?73 de Fer IW1DTU On Thursday, May 31, 2018, 8:33:34 AM

Hello WEI Mingchuan,
congratulations for your mission and many thanks for DSLW-B info.
Can any gnuradio Guru write a short guide on how to set parameters on
gnuradio Live CD?
Please, not interested in how to download the .iso file but wich parameters
set and in which way in gnuradio window when the Live Cd is up and running.
Thanks in advance

Hi OMs,
We are planning two tests for UHF of DSLWP-B, from 31 May 16:00 UTC to 31
May 18:00 UTC, and from 1 Jun 02:00 UTC to 1 Jun 04:00 UTC.
We will change the mode of the transmitters to 250 bps GMSK and JT4G on
435.4 MHz (GMSK every 5 min, JT4G every 10 min, JT4G has higher priority),
and 250 bps GMSK on 436.4 MHz (every 5 min). Corresponding demod grcs should
be used.
Some more tests are planned on Jun 3, and detailed time TBD.
The temperature of onboard batteries is a little higher than expected,
that's why UHF is not always on.
