Information, documents and hints on working with NXDN radios
NXDN is a Common Air Interface(CAI) that is part of a consortium of companies. Kenwood and Icom are major players, although there are other companies that also produce products. NXDN uses Frequency Division Multiple Access (FDMA), and uses either 6.25khz or 12.5khz of bandwidth.
