This month was dominated by the travel and attendance at the Pacificon and WASPAA 2025 conferences.

A write up of our Pacificon attendance is here. WASPAA is a professional level acoustics and speech conference where I (along with Jean-Marc) presented a poster paper on RADE V1. This was well received by the other attendees. It was pointed out that RADE V1 is the first known real-world deployment of a neural codec – an important milestone that the Ham community can be proud of. Several attendees also thanked me for Codec 2 – it is used in academic research as a (low quality) “control” for various projects.

Earlier in the month prior to the conferences I worked on integration and testing of the fine timing algorithm with the core RADE V2 decoder. However I hit some performance degradation that I traced to jitter in the timing estimator. At WASPAA, Jean-Marc developed an alternative timing estimator that I am now evaluating – thanks Jean-Marc!

Promotional efforts this month included a ARDC blog post on the BBFM work, and working with Kanda-san JH0PCF on a RADE V2 magazine article.
