The Texas Slow Net (TSN) operates daily at 7:45 PM local time on 3570 KHz, serving as a dedicated traffic handling training net within the National Traffic System. It specifically caters to operators aiming to enhance their **International Morse Code** skills and learn proper CW traffic net procedures. Each session incorporates a traffic handling lesson delivered as a radiogram to all participants, reinforcing practical application. The resource provides guidance on effective Morse Code learning, emphasizing sound recognition over visual dot/dash counting, suggesting characters be sent at 15 words per minute with adjusted spacing. It recommends listening to W1AW code practice transmissions, setting goals with ARRL's Code Proficiency Program qualifying runs, and regular participation in NTS traffic nets. The content also references the ARRL's Public Service Communications Manual, particularly Section 2, which details the **National Traffic System**.
