On my very expensive scoop (hi) you see a packet frame @ 1200 Baud received from a station about 50 kilometers away. Looks fine to me.
After updating the Firmware from version V2.35 to V2.81 I see a good increase in the decoded frames.
How to update the Firmware
wget http://tarpn.net/zflash2020oct/tarpnflashinstaller.sh chmod +x tarpnflashinstaller.sh ./tarpnflashinstaller.sh Run tarpnflash usb * My Ninotnc is connected to ttyACM0. tarpnflash version ttyACM0 * Is there a newer version available in the dir "ninotnc" you can run. tarpnflash flash ttyACM0 (version number) * Now the Firmware is being updated. * Check if the flash of the firmware went well. tarpflash version ttyACM0 * Great now running Version v2.81 /dev/ttyACM0 NinoTNC v2.81
I immediately built my second NinoTNC. I am very curious how that works with IL2P mode, Improved Layer 2 Protocol. In the picture below, the two NinoTnc`s are running at 2400 Baud with IL2P mode. Functions perfectly. Now I have some problems with adjusting to 4800 and 9600 Baud. I have to look into this.
