The graphite nozzle is nearly finished. Only the O-ring grooves remain to be cut. Time to clean-up after a messy day in the workshop. Despite the vacuumcleaner, still a lot of dust.

GPS SMS transponder

dsc04282

The Talky GPS transponder uses a dra818U radio module. Unfortunately, this module transmits harmonics at higher frequencies, interfering with other electronics.  Now that the Talky GPS transponder is equipped with a low-pass filter, this problem is solved. This now allows the GPS SMS transponder to work within the vicinity of the Talky GPS.

The GPS SMS transponder transmits coordinates at a 2 minute interval at ground level. When launched, the GPS SMS transponder transmits every 30 seconds.
