INTRODUCTION OF K MODES
K1000 Full SubGHz (Coming in ExpressLRS V3.5)

Yes, you read that right—1000Hz in the 868/900MHz domain! While this mode is designed for maximum data throughput when used with MAVLink, don't let the 1000Hz fool you; during development, it was tested for long-range performance.

DK500 (Coming in ExpressLRS V3.5)

Designed specifically from the ground up for speed enthusiasts and RC reliability. K modes are next-generation FSK modulation with built-in packet repair (Forward Error Correction). Similar to FLRC D500, DK500 sends repeat packets to minimize packet loss in challenging race environments. Paired with a Gemini-enabled Tx and Rx, nothing compares to its RC reliability.

NEW PACKET RATES
Sub-GHz 200Hz Full (-111dBm)

Optimized for MAVLink: Double the packet rate of current 900MHz SX1276 hardware, tailored specifically for MAVLink users to provide a more robust link and reduced interference.

Dual Band X100Hz Full (-112dBm)

Enhanced Gemini Mode: Enjoy dual-frequency transmission with a 100Hz packet rate and full 16-channel resolution, ensuring strong and stable connectivity even in challenging environments.

Dual Band X150Hz (-112dBm)

Gemini Mode: Experience simultaneous sub-GHz and 2.4GHz transmissions, offering robust performance and reduced interference with a packet rate of 150Hz.

Sub-GHz 250Hz (-111dBm)
