Would it not have been better to start a new thread instead of hijacking a system admin notice!! Then this useful info could be found by others, instead of being submerged and not responding to

Thanks when i get time i will make it so you can save permanent settings to be more easily deployed in the field along with menus to perhaps set frequency or other options and display default values

I purchased a tnc-black for my BBB and have it working with a serial port interface. I've been unsuccessful in using the RPi programs to get the i2c interface to work on the BBB. I don't think there

Very good job! I'll try it soon. 73s Ale IK1PLD

Hi, it is essential to add a low bass (or band pass) filter to reduce the harmonics. The raspberry output contains high odd harmonics, up to many hundreds of MHz. You can search the web for online

You will certainly need a Low Pass Filter. Good luck and 73 Clive GW0PPO
