Guide how to set up APRS to Kydera CDR300UV
Basic guides
1. Update radio to the latest firmware and use proper software
2. Always read code plug from radio, make a change to code plug and then write back to the radio, because in this case your code plug will have all
correct data that match to your radio
3. Never write data to the radio from different version of CPS, while this will lead to unpropped function/working of your radio.
