The satellite launched April this year known as Capitan Beto, is
recovering from its balance of energy that caused transmitter to be
turned off for several days.

This was achieved after one of the AMSAT-LU stations in coordination
and in conjunction with Satellogic team, send a command to reconfigure
onboard software to turn off attitude control circuits feeding
magnetorquers this last weekend .

Telemetry text mode command taken before change can be seen at

Operation was done using RTL dongle, connected directly to antenna,
using HDSDR recording software as IF mode only, that helped not to
record big amount of data from Orbitron connected to DDE, also
automatically compensating Doppler, see

command sent and satellite response below.

After reset, Cubebug-1 went to 'mission state', batteries showing
adequate level of charge.

Good reports were received from several amateurs from different parts
of the globe.

This activity is performed as part of the agreement of mutual
collaboration that Satellogic & Amsat-LU signed on July 2013.

We recall that the satellite transmits now at 1200 bps AFSK, on
437.438 KHz, broadcasting packets every 30 seconds, signal is low
requiring directional antenna and preamp for adequate reception.
