The W6JWS 2-meter Repeater Maintenance and Repair Log documents the ongoing upkeep of a 146.745 MHz repeater, specifically addressing modifications to enhance its functionality. It details changes made to ensure the repeater powers up in _PL mode_ and to improve the reliability of touch-tone control, drawing comparisons to similar work performed on the AE6KE repeater. The log also notes a repair to a fused wire in the reverse battery protection circuit after an accidental polarity reversal, highlighting a temporary workaround where a wire was omitted but the system remained operational. The resource includes practical insights from Jeff Liebermann, AE6KS, regarding jumper configurations and programming, with accompanying photos. It provides access to several documents for the Icom RP-1510 repeater, including operating manuals and a schematic for the single logic board version, which differs from the dual-board configuration described in some printed manuals. The log mentions a specific modification to adjust the dropout delay, which was later deemed unnecessary, and references a related project for the AE6KE repeater, aiming to replicate successful modifications on the W6JWS machine, resulting in improved touch-tone reliability and proper PL mode activation.
