Help build better default calibrations for your radio — send in your calibration.user.json

[mm5agm]

YWC's default S-meter, power, SWR, ALC, compression, VDD and IDD calibration tables were measured against an FTdx101MP. From v2.3.0 (currently on the develop branch) we're shipping per-model placeholder calibrations for FTdx101D, FTdx10, FT-710, and FTDX3000 — but those placeholders are just copies of the FTdx101MP table because the only radio I can measure against is my own.

If you own one of the non-FTdx101MP radios and have time to calibrate even a few of the meters using YWC's in-app Meter Calibration page, please send your calibration.user.json back to us. We'll merge submissions for the same radio model — averaging two or three users' calibration data is much more representative than guessing from one.

How to submit:

1. In YWC, top nav → Meter Calibration.

2. Pick a meter (start with S-Meter since that's the most visible). Enter a few raw-vs-displayed values your radio actually reads, save.

3. The file lives at:

   %APPDATA%\MM5AGM\Yaesu Web Control\calibration.user.json
   

   Open File Explorer, paste that path into the address bar.

4. Tell us your radio model and drag the file into a reply on this Discussion thread. Or attach to a fresh post if it feels off-topic here.

S-meter especially is high-value — Jacek (SP3L) reported in #29 that his FTdx10 reads about 2 S-units lower than the radio's own meter, which is the exact symptom this campaign is meant to fix.

Thanks in advance — every submission helps every user of the same radio.

Please find attached the json file Colin mentioned above. The data in this file is applicable for my FTdx10 radio.

I do not know if this is relevant, but just in case, my FTdx10 firmware versions are:
MAIN: V01-15
DISPLAY: V01-06
DSP: V01-20
SDR: V01-02
AF: V01-00

On my Windows 11 PC, \I found the json file:
C:\Users\Jacek\AppData\Roaming\MM5AGM\Yaesu Web Control\

calibration.user.json

Thank you Jacek — this is exactly what was missing. First real-world FTdx10 calibration data.

I'll bake it into calibration.default.FTdx10.json in v2.3.7 so every new FTdx10 install starts with sensible measured numbers instead of the FTdx101MP placeholder copy. Firmware info noted too — useful to capture in case S-meter response varies across FTdx10 firmware revisions.
