  • firmware compiled with -odM4 flag which disable faulty optimization
  • serial port speed can be set
  • new telemetry mode is available, you can directly connect uBlox GPS and use it.
  • new parameter timeToFS making possible to setup time to fail save activation
  • single servo mode, first channel value could be output as standard 50Hz servo PPM signal. It make possible to control single servo directly from receiver.

You can download it from download page.

This is raw RSSI value report by LoRa modem, using lowest possible TX power less then 23dBm (less then 250mW), and non directional antennas.

Oct

I recently bought simple sweep spectrum analyzer, and now i can measure and tune all my antennas.

Moxon antenna i made was not so good tuned as expected, so I made another one.

Now it looks much better ๐Ÿ™‚

Moxon Antenna for LRS TX

May
31

This is first Moxon antenna I made. It looks like having 5db more gain then RMILECย  SRC771 1/2 Wave Length Antenna (according my simple measurements).

As always my RF generator’s used to drive TX antenna, and Immersion RC power meter, connected to dipole antenna to measure signal level.
