 You'll generally find packet nodes on the following frequencies. Note that whilst the Bandwidth is set, the usage may vary.
-==== VHF ====
+==== VHF / 2m ====
-Usually 1200 Baud, Standard AX.25
+The default "legacy" mode is 1200 baud standard AX.25, though newer modes, modulations and encodings are starting to appear, offering more resilience and throughput.
