Hello. Here is the latest version of a set of two patches for the soundmodem application that I have created to fix AFSK operation at bit-rates lower than 1200 baud (e.g. 300 baud for HF packet radio or APRS).
Patch 2/2 follows: This patch might be useful for successful reception at 300 baud. It uses longer RX tone filters (at the expense of CPU time).
