Every one of the region presets named a modulation no mesh runs any more, and
two of them named a frequency nobody was ever on.
MeshTerm's list was three regions on 250 kHz / SF11 — the shape MeshCore
shipped with — plus two trade-off rows built on the EU frequency. Through 2025
most regions left that modulation for a narrow 62.5 kHz one, so the EU row is
what MeshCore now calls "EU/UK (Deprecated)", the US row had the right
frequency with the wrong modem (910.525 is SF7/BW62.5/CR5), and "AU / NZ 915"
at 915.525 was not a preset at all: Australia is 915.800 wide, 916.575 narrow,
923.125 in SA/WA and QLD, and New Zealand is 917.375. Four parameters have to
match for two nodes to hear each other, so a stale table is a radio staged onto
an empty channel.
The list is now MeshCore's own suggested settings, mirrored verbatim — names,
order and values — from what its apps, the web flasher and config.meshcore.dev
all read at api.meshcore.nz/api/v1/config. Twenty-three regions, including the
two MeshCore still lists under its own "(Deprecated)" names, because nodes that
never re-tuned are on them and picking one is how you go and listen. The names
are spelled as MeshCore spells them so the row can be read against the phone
app.
Four regions also name a path-hash size, which the preset now stages alongside
the radio fields as the firmware's mode (size - 1), exactly as MeshCore's own
config GUI converts it. The rows moved to the two-lane menu shape — name, then
the parameters in MeshCore's print order — which fits 53 columns where the old
one-line title ran to 85, and the list opens on the preset the radio is already
tuned to, staged values included, so picking a neighbour is a comparison rather
than a guess.
The trade-off pair is gone with them. They were ours rather than MeshCore's,
they pinned a deprecated EU frequency onto whoever picked them, and the wide /
mid / narrow choice they were reaching for is one the region list now makes
properly per region.
The simulator boots on the firmware's build defaults too (869.618, BW 62.5,
SF8, CR5 per MeshCore's platformio.ini), rather than on the settings the EU
mesh left behind.
