A great technical discussion unfolds on weather-proofing coax connectors, with operators comparing coax-seal, heat-shrink, self-fusing tape, and other tricks for keeping water out in the wild. The roundtable also tackles repeater intermod, how it happens, why it’s so stubborn, and what solutions are in the works. It’s another night of practical advice, shared experience, and good humor on 985.

In this week’s 985 Workbench, hosted by Ron (WA3VEE) from West Chester, PA, the group dives deep into all things ham radio—from tower-raising tales to a lively discussion on Linux for the modern shack. Operators share updates from the New Holland Hamfest, progress on Joe’s massive tower project, and the challenges (and victories) of running Windows software on Linux Mint, Ubuntu, and even Raspberry Pi setups.

With great stories from familiar voices like CR, Chuck (NA3CW), Bill (KC3OOK), Jim (AF3Z), and Simon (KD3BPI), this episode covers everything from grounding rods to GUI interfaces—with a side of humor, tech tips, and camaraderie that makes 985 a Monday-night favorite.

📻 Highlights:

• Tower base installation success and near-misses
• Linux for ham radio: Mint, Ubuntu, Wine, and beyond
• Hamfest finds and classic gear restoration
• Real-world shack challenges and solutions
• Community check-ins from Pennsylvania to Massachusetts

Host: Greg (W3DIB) | Focus: CW Speed, Learning, and Classic Features like AutoPatch

This week’s Monday Night Workbench was part Q&A, part nostalgia trip, and part CW masterclass. Operators shared updates from their shacks — from drone-assisted dipole installs and antenna coax upgrades to prepping for Winter Field Day and even chasing DX into New Zealand and Australia on 10 meters.

The main discussion centered around Morse code (CW) — particularly operator comfort speeds and how to improve. Most agreed that 20–25 WPM is a sweet spot for field events, though some ops operate much faster in contests. Newer CW learners shared their struggles and tips, including online training tools like morsel.fun and LCWO.net, plus simple listening practice on 40 meters or via WebSDR and ARRL bulletins. Veterans stressed that speed comes naturally with practice and that events like POTA, Straight Key Century Club, and Field Day are ideal low-pressure environments for improving skills.

The group also revisited AutoPatch — an old-school feature allowing hams to make phone calls through a repeater using DTMF tones. While largely obsolete today thanks to cell phones and VoIP, it was once vital for emergencies and roadside calls. A few repeaters still support it, but usage is rare.

Other highlights included discussions on tower projects, Winter Field Day planning, and a deep dive into repeater etiquette and digital access. As always, the net wrapped with thanks to Joe (W3GMS) and a reminder to join the Thursday night Roundtable.

• KC3NZT: Shared a quick shallow-trench method: “temporary becomes permanent.”
• NA3CW: Recommended running a rope inside conduit to wick moisture and allow future pulls.
  ➡️ Consensus: Both burial and overhead suspension are viable — burial offers neatness and permanence, messenger wire provides accessibility.

Closing Notes

• Late check-ins included KC3NZT (Harvey), AF3Z (Jim), and W3JAM (Jeff).
• The net wrapped up with the usual humor about running up Joe W3GMS’s electric bill.
• Reminder: Thursday Night Roundtable at 8 PM will be hosted by Luke – KC3SCY.

This session of the 985 Workbench was hosted by Greg, W3DIB, from Kennett Square. The meeting began with check-ins from both digital (EchoLink/AllStar) and RF stations. Greg reminded participants about repeater etiquette, including leaving pauses for digital users, waiting a moment after PTT, and managing the repeater’s three-minute timer.

Notable announcements included a reminder to register for digital access through the W3GMS website and an update on repeater intermod interference. Ron, WA3VEE, reported on Joe W3GMS’s health, noting he was recovering well in the hospital.

Technical Questions and Answers:

1. AM Control Carrier vs. Plate Modulation –
   Bill, KC3OK, asked about differences between control carrier modulation and plate modulation.
   • John, WA3KFT, explained control carrier modulates the screen rather than the plate, making it cheaper but prone to screen burnout if overdriven.
   • Chuck, NA3CW, expanded on the topic with examples from high-power broadcast transmitters and dynamic carrier control systems, illustrating how varying carrier power can improve efficiency and save costs.
   • Jim, AF3Z, noted control carrier setups are less prone to overdriving and distortion.
2. Mobile Noise with Baofeng & Mag-Mount Antenna –
   Simon, KD3BPI, described crackling noise on both transmit and receive when his Baofeng HT was used with a mag-mount antenna at speed.
   • Chuck, NA3CW, suggested static buildup as the likely culprit, recommending grounding the antenna or radio to the vehicle chassis.
   • Wayne, KC3SQI, and Ron, WA3VEE, advised using a cigarette lighter power adapter to provide a proper ground path.
   • Other stations noted that moving the mag-mount or using better connections could improve performance.
3. Emergency Traffic Procedures on Nets –
   Mike, W3MFB, asked why emergency breaks are not formally called for during the net.
   • Ron, WA3VEE, and Jim, AF3Z, explained that in ham radio, emergencies are signaled by “break break” between transmissions, and all stations yield immediately. Formal emergency prompts are generally unnecessary but pauses during transmissions allow emergencies to break in.

Other Highlights:

• Randy, K7RAN, joined from Salt Lake City via AllStar, testing DV Switch.
• Multiple operators shared updates about antenna work, tower projects, and repairs.
• Chuck shared a tip on using peppermint oil to deter ants from equipment enclosures.

Technical Questions & Answers

1. Battery Size for Xiegu G90 (W3MFB)

• Question: What size LiFePO₄ battery is optimal for portable use with the G90, which draws ~6A on transmit?
• Key Points:
  • Ron (WA3VEE): 15Ah suggested; size depends on transmit time and discharge specs.
  • Jim (KC3RFG): Uses a 10Ah Dakota Lithium successfully for all-day use; G90 tolerates lower voltages.
  • Tim (W3QP): At least 6Ah to meet current demands; 10–15Ah ideal. Spreadsheets exist to calculate exact needs.
  • Consensus: A 10–15Ah LiFePO₄ is a good balance of portability and runtime.

2. Mounting Antenna Switch Box (KC3SQI)

• Question: Should a plastic weather-protected switch box be ground-mounted or placed on the mast?
• Advice:
  • Ron (WA3VEE): Mount on the mast for protection from lawn crews and ease of maintenance.
  • CR (W8CRW): Uses a raised Pelican-type case behind protective barriers.
  • Chuck (NA3CW): Suggests painting the box for UV protection and using protective conduit for cables.
• Consensus: Mount on the mast or a stabilizing leg, with protective measures.

3. FT8 Timing & Local Interference (KI6OM)

• Question: Should FT8 transmissions on 6m sync with nearby stations to avoid receiver desense?
• Discussion:
  • Tim (W3QP): Unsure it’s critical; use a clear frequency and hold transmit frequency.
  • Vic (KC3TYX): Always uses “Hold TX Freq” to avoid overlap.
  • General Consensus: Good practice to avoid overlapping frequencies, but syncing odd/even cycles with others is unnecessary unless dealing with very strong nearby stations.

Additional Notes

• Grounding Concerns: Following AF3Z’s neutral line issue, KC3RFG recommended a Megger test on ground rods to evaluate grounding effectiveness.
• Pelican Cases: Recommended for outdoor electronics due to durability.
• Wildlife & Safety: Beekeeping and wildlife around homes were discussed, including safety considerations for allergic reactions.

General Discussion Highlights:

• Noise Hunting with Direction Finding: Chuck (NA3CW) described tracking down an S9 noise issue on 75 meters, suspected to be caused by a faulty lightning arrester on a utility pole. He used a handheld with a directional AM antenna tuned to 136 MHz to pinpoint the source.
• Antenna Adventures and Propagation Notes:
  • John (KC3WWC) activated a new state game land for POTA with good shade and low noise.
  • He also experimented with two APRS-capable radios and noted six-meter openings into Florida and later Wisconsin, all on a simple backyard wire.
  • Mike (W3MFB) reported a strong 17m opening, working Switzerland and hearing Spain and Ireland, while noting 10 meters was surprisingly quiet.
• Travel and Light Operating: Chuck visited the Pennsylvania Grand Canyon and Corning Glass Museum, with light HF activity later in the week. Tim (W3QP) operated mobile HF from Assateague Island, including a memorable QSO with NASA's special event station for the Apollo 11 anniversary.
• Recruiting for Ham Radio: Ron (WA3VE) shared a story about connecting with his vet’s son, who’s interested in STEM and communications. He plans to organize future demos and station visits.

Technical Question Segment:

• Power Line Mystery – Voltage Rise Under Load:
  Jim (AF3Z) posed a curious question: why does his line voltage increase when heavy appliances like a sump pump or microwave kick on?
• Answer (provided by Bruce KS4CK, Ron WA3VE, and Chuck NA3CW):
  • The likely cause is a bad or loose neutral connection in the home's electrical service.
  • When neutral fails, loads become unbalanced between the two legs of 240V split-phase service, causing voltage to drop on one leg and rise on the other.
  • This could be in the meter pan, panel bus bar, service entrance, or even the transformer shared with a neighbor. Immediate attention by a utility or licensed electrician is recommended.

Important PSA:

• Threat to 70cm Band – FCC Docket 25-201:
  • A commercial satellite company, AST SpaceMobile, has petitioned the FCC to use part of the 70cm band (430–440 MHz) for satellite operations.
  • Stations expressed concern this may interfere with amateur satellite operations, digital links, and repeater inputs.
  • Ron encouraged everyone to file comments before the deadline using pre-written language and a direct FCC link provided via club email. Docket number is 25-201.

Miscellaneous Notes:

• Call for Hosts: The Thursday Night Roundtable needs a volunteer host this week, as Jack (K3YVQ) is unavailable.
• Light Net Turnout: The great weather may have kept many operators out of the shack, leading to a shorter-than-usual session.
