Packet.Rig.Flrig 0.23.0

Packet.Rig.Flrig

IRigControl over flrig's XML-RPC server (default 127.0.0.1:12345). The client contract deliberately mirrors hamlib's own flrig backend (rigs/dummy/flrig.c) — the most battle-tested flrig client — including its meter conversions, so both report identical values.

await using var rig = await FlrigRig.ConnectAsync();

Console.WriteLine(rig.Info.Model);          // rig.get_xcvr
Console.WriteLine(rig.FlrigVersion);        // main.get_version

await rig.SetFrequencyAsync(7_074_000);

// flrig mode names are rig-native — enumerate before you set:
Console.WriteLine(string.Join(", ", rig.SupportedModes));   // e.g. LSB, USB, CW, DATA-U
await rig.SetModeAsync(RigMode.From("DATA-U"));

var swr = await rig.ReadSwrAsync();         // rig.get_SWR, falling back to get_swrmeter
var watts = await rig.ReadRfPowerWattsAsync();

// Anything else on flrig's method table:
await rig.CallRawAsync("rig.cat_string", ["FA;"]);   // raw CAT passthrough

flrig dialect notes (handled for you)

• Frequency gets return strings of Hz (rig.get_vfo); sets take XML-RPC doubles (main.set_frequency).
• Mode names are whatever the attached transceiver calls them. Setting a mode outside SupportedModes throws instead of being silently ignored (flrig drops unknown mode strings without complaint — and the server-side "Ignore xmlrpc mode changes" option drops all of them).
• The get side reports no passband width (PassbandHz is null), and widths cannot be set.
• SWR uses the newer direct rig.get_SWR when present, else interpolates the 0–100 rig.get_swrmeter deflection through hamlib's anchor table (capped at 10:1).
• Power: rig.get_pwrmeter (0–100 deflection) scaled by rig.get_pwrmeter_scale — relative = deflection/100 × scale, watts = deflection × scale (hamlib's exact contract).
• Meters are only meaningful while transmitting; flrig answers 0 when idle or unmetered.
• Poll-only, multiple clients supported by flrig, state can change under you.

Testing: flrig is a GUI app with no headless mode — this package's tests script an in-process XML-RPC fake (the established technique for flrig clients).
