Packet Radio and AX.25 Fundamentals

AX.25 packet frames carry addressed digital data over radio; baud rate, deviation, audio levels, timing, digipeater path, channel load, and link quality determine whether packets survive.

Start with the practical answer: AX.25 packet frames carry addressed digital data over radio; baud rate, deviation, audio levels, timing, digipeater path, channel load, and link quality determine whether packets survive.

What changes the result

Digital systems combine RF link, modulation, access parameters, station identity, routing, network services, and application behavior.

The mistake to avoid

A web dashboard or internet bridge does not prove the intended RF path, protocol compatibility, or emergency independence.

Use this operating sequence

Verify each layer separately, use truthful identifiers and current local parameters, monitor channel load, test two-way traffic, and keep an analog or direct fallback when appropriate.

Source boundary

Current controlled CKB RF engineering, VHF/UHF, operating, and diagnostic references. Confirm current local coordination, band plans, satellite data, and equipment documentation before operating.
