Chuck (NA3CW) hosts the W3GMS Monday Night Workbench as stations check in from icy Pennsylvania, share week-in-radio updates, and work through a set of practical bench questions. Topics include choosing alignment/trimmer tools (plastic vs ceramic and why non-conductive matters), whether extending a G5RV makes sense (and how ladder line length impacts multi-band behavior), and a late-breaking troubleshooting deep dive on diode/rectifier testing in a potted assembly—covering common diode failure modes (shorts, opens, leakage) and what you can realistically verify when you can’t lift a lead.
