Thanks for sharing!
Hoping to receive my first meshtastic devices in the mail next week 😊
I hope it would be a fantastic experience. Please feel free to ask if you have any question about it. Thanks for sharing your thoughts.
@@technologymasterkam Will do.👍 I can't wait to try them out.
Hoping to use them for communications in remote wilderness areas.
Interesting video, I was suprised using two apps simultaneously with different setting. But one thing I am missing here:
The modules with SX1262 typically have 2 different LCR component placements, one setup for LF (433MHz) and another for HF (868+915MHz).
I guess there will be some losses, if using a frequency which was not intended by the actual component placement.
It is very interesting to find out if there are losses, YES must be. I have just posted a video which I hope you will enjoy. It will provide you with more info. Thanks & welcome for sharing your thoughts. ruclips.net/video/Ke2e0uyvDZ4/видео.html
Hello. Heltec wireless tracker boards have a hardware selection of the operating frequency range. The jumper is located between the Lora and GNSS antenna sockets.
Please send me the source of your information, if you want to help people.
@@technologymasterkam The source of my information is an inspection and comparison of two Heltec wireless tracker boards. One for the frequency range 433-510 MHz, the second 863-928 MHz. The first has a jumper on the contacts designated "RLF", the second jumper closes the "RHF" contacts. I would also like to note that the printed circuit connecting the SX1262 chip and the antenna connector has a choke and two capacitors of unknown value. It is quite possible that the choke is an antenna extension coil. In this case, the matching of antennas of 433 and 868 bands will not be interchangeable. In addition to all of the above, I noticed that the antennas included in the kits are poorly matched to European bands. For example, changing the frequency from 868 to 915 MHz gave a significant increase in signal level, signal-to-noise ratio and communication range. The antenna of the 433-510 kit is tuned to a frequency of approximately 480 MHz.
@@technologymasterkamAn inspection of both Heltec wireless tracker boards 433-510 MHz and 863-928 MHz showed that the first one has a jumper on the “RLF” contacts, the jumper on the second board closes the “RHF” contacts.
you have 902.125 for long_fast in US but I have 906.875
@@isthereafeeforthis 902.125 is confirmed. You can have a different frequency due to any other configuration change. If you need further help, please share you configuration for LORA.
