Alan,
These can be decoded, and they look like a version of CanalSat, except that the duration of the bits is 640 uSec instead of 500 uSec. So please go ahead an learn all the signals. The executor should be trivial to modify so that it sends the longer duration.

OK, the box uses Zaptor instead of CanalSatLD. Zaptor can be sent at either 57KHz or 36KHz. The upgrade from UEI shoots Zaptor at 57KHz, while your learns were at 36KHz.
