Time to release new firmware 🙂 What’s new: support for old and new modules (hw version 1.1 for old, and 6.2 for new one) 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 […]

RSSI checked at 5km distance
This is raw RSSI value report by LoRa modem, using lowest possible TX power less then 23dBm (less then 250mW), and non directional antennas.
QCZEK LRS is working very well :)
Finally I found time to test it.
Development of Qczek LRS
Months ago i started to develop custom firmware for cheap 1W LORA module, to use it as LRS RX/RX devices. Now it’s almost ready for testing 🙂
Blejzyk is flying ;)
This is relay nice FPV glider 🙂 Build log
LRS Moxon antenna v2 (tuned)
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 🙂
Blejzyk FIRST – build log
I decided to use Blejzyk FIRST glider as my next FPV platform… So I 3d printed some parts, instead using wooden.
Li Ion batteries are not safe as you think
My Ranger catch fire after crash 🙁
CG Machine
An absolute must for RC hobbyists 🙂
Moxon Antenna for LRS TX
This is first Moxon antenna I made. It looks like having 5db more gain then RMILEC 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.
