The RF section shipped as four bare fields; restore a prepopulated plan list (dropdown) with Custom unlocking free entry, per operator direction. Preset labels carry the full values, so the number fields render only in Custom mode — no duplicated display. Presets limited to verifiable sources: the repo's MeshCore community plans (EU 868/433), the MeshCore firmware's own build defaults (platformio.ini arduino_base 869.618/62.5/ SF8 CR5; companion example 915.0/250/SF10/CR5), and the operator-attested Portugal plan (869.618/62.5/SF8/CR8). Stored params are matched back to a named preset on load; hand-editing flips the dropdown to Custom. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
