An FTDX3000 rejects every FA command: the FTDX10 family writes a frequency in nine digits and everything before it — FTDX3000, FTDX5000, FTDX1200, FT-2000, FT-950, FT-450 — writes eight, answering the longer form with "?;". The rig would not follow and nothing said why. The width is LEARNED from the rig's own replies rather than tabulated: it announces the format in every answer to FA;, so it comes from the radio in front of the operator instead of from a model list that is always one release behind — and a Yaesu this backend has never heard of is right on the first read. Nine until the first reply lands, which is what the modern rigs use and what this backend was written against. The five older ID codes are named too, so the console says FTDX3000 rather than a bare number.
