Module sdcard 

SD card file format parsers for the TH-D75.

The TH-D75 stores configuration data, logs, recordings, and captures on a microSD/microSDHC card (up to 32 GB, per Operating Tips §5.14). These parsers allow reading and writing radio data without entering MCP programming mode – just mount the SD card via USB Mass Storage mode (Menu No. 980) or remove it physically.

Per User Manual Chapter 19:

• Supported cards: microSD (2 GB) and microSDHC (4-32 GB). microSDXC is NOT supported.
• File system: FAT32. Maximum 255 files per folder.
• Format via Menu No. 830 (erases all data).
• Unmount before removal via Menu No. 820.
• Export config: Menu No. 800-803. Import: Menu No. 810-813.
• Mass Storage mode (Menu No. 980 set to Mass Storage): the radio appears as a removable disk on the PC. RX/TX and recording are disabled in this mode.

Per User Manual Chapter 20 (Recording):

• Recording format: WAV, 16-bit, 16 kHz, mono.
• Up to 2 GB per file (approximately 18 hours). Continues in a new file if exceeded.
• Recording band selectable: A or B (Menu No. 302).
• Recording starts/stops via Menu No. 301.

Per User Manual Chapter 19 (QSO Log):

• Menu No. 180 enables QSO history logging.
• Format: TSV (tab-separated values).
• Records: TX/RX, date, frequency, mode, position, power, S-meter, callsigns, messages, repeater control flags, and more.

Encoding

All parsers accept &[u8] input — the caller decides how to read the file (e.g., std::fs::read, memory-mapped, etc.).

The repeater list and callsign list use UTF-16LE encoding with a BOM. The QSO log and GPS log use plain ASCII/UTF-8 text.
