<h2 id="manual-overview">Manual Overview</h2>
<p>The Heathkit PACKKIT Model HK-232 manual update introduces new commands and features, including the NAVTEX mode, which enables the reception of marine weather broadcasts on 518 kHz. Troubleshooting involves understanding the new commands such as AFILTER, which filters ASCII characters, and BBSMSGS, which modifies status message formats for compatibility with certain BBS software. The NAVMSG and NAVSTN commands allow selective monitoring of NAVTEX message types and stations, respectively. Error diagnostics include the checksum verification indicated by $A7 in the sign-on message. Calibration and adjustments are addressed through modified commands like CBELL, which now sends bell characters on both connect and disconnect events, and CODE, which supports additional characters for Morse and RTTY modes. The HELP command provides an on-line guide to available commands without interrupting ongoing operations. These updates aim to enhance the functionality and compatibility of the HK-232 controller across various communication modes.</p>
<h3>Quick Issues Covered</h3>
<ul>
<li>Diagnose NAVTEX mode message filtering with NAVMSG and NAVSTN commands.</li>
<li>Adjust AFILTER to manage special character transmission issues.</li>
<li>Resolve BBS message format issues with BBSMSGS command.</li>
</ul>
