LoRa trial news: frequency and parameters change
After a long time testing on 433MHz, i never reached the wanted target. The range was always too much short than expected.
This seems due to a great noise floor and interferences on the 433 ISM band at the gateway premise.
Few weeks ago i decided to install a second gateway working on the 868MHz ISM band.
After many tests i got the best results using these parameters:
- Frequency: 865200kHz
- Channel bandwidth of 62.5kHz
- SF 9
Here is the snapshot of the best tracking of about 25km:
SF 9 is the right SF number to send the payload needed for tracking infos in a reasonable time; so to enhance the coverage, i have only two options:
- to narrow the channel bandwidth to 20.8kHz (width interesting also to be compliant width the HAM channel spacing) gaining about 4db. The intervention isn't so easy because che poor components used on the sensor device introduce a clock drift that cause the lost of alignement between the two station, breaking the demodulation process. Higher quality components and/or a support of TCXO will be investigated for better performances;
- build a well-tuned collinear antenna of 5dbi on the tracker side; and this will be done soon.
Infos will be published when available.
Arduino sketch and configs are available on demand.
The first Ham LoRa application server in Turin is UP & Running!

The first Ham LoRa application server in Turin is UP & Running!
Tuned on 433.375MHz, a LoRa gateway built with the Dragino hardware has been set up in Torre Bert.
It's open for testing purposes.
The basic modulation parameters to use are:
* the channel bandwidth of 20.8KHz
* the spreading factor of 8
A structured data record must be composed to have a live monitoring displayed in real time at this LoRa application server. For the test i used a 'tracking sensor' based on ARDUINO with GPS and a LoRa shield. Now the server is under maintenance for internal debug use. When bug will be fixed, it will look like the 'APRS.fi' in displaying the received tracking sensors; Chrome is the better browser to access this service. The first running version will be announced in few days. If interested in trying to use, write me an email.
Have fun with IoT wireless communication!

Drone video recording trial in towers sites
A second movie featured a "tower inspection". During the mission, in unknown condition/position,
strong EM fields disrupted the gimball control causing the need to land and reset the device.
The effects are recorded in the movie starting at 5'34"

Radios through RF SoftRock sampler
The original WebSDR software.
The antenna is a Maxiwhip.
Listen to rpi.ham.radio.it, tuned on variable frequencies (i.e. 14150kHz now).
