LinHT Progress

A couple months ago Wojciech Kaczmarski SP5WWP announced the LinHT project. These mad lads buy a Retevis C62 radio and replace all the circuit boards inside with their own. They aim to create an open-source hardware, Linux based, SDR handheld transceiver. Their first boot of the OS happened on August 18.

Last week, Wojciech, Andreas OE3ANC, and Vlastimil OK5VAS hit a major milestone: the radio now works as a complete M17 transceiver.

A few days later, Vlastimil submitted a PR for the first iteration of Revision B of the circuit boards, which includes:

• a 5W amplifier
• new audio codec
• a redesigned power system which can charge from USB-C with simultaneous operation of the radio

Rev B is not yet ready for manufacturing, but I’ll be following closely and can’t wait to buy one.
