• 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.

❓ Technical Questions Addressed

1. Running Amplifiers Without ALC Feedback
   From W3JAM: Using a Ten-Tec Centurion amp without an ALC return.
   • Answers: Scope use is critical to avoid splatter, especially for AM operation. ALC loops react too late to prevent overdrive.
   • Consensus: Monitor drive level carefully; a scope is the best safeguard.
2. Proximity to Transformers and HF Noise
   From KD3AIS: Is it better to live near or far from a transformer?
   • Summary: Transformers rarely generate noise themselves; cracked insulators, lightning arrestors, and aging hardware cause the bulk of HF noise. Being close to a transformer may actually be better due to lower impedance and fewer neighbors injecting noise.
3. AL-80 Amp Showing Idle Plate Current
   From WA2JTS: Plate meter jumps to ~50 mA on power-up, even when idle.
   • Advice: Could be leaky relays or gas in the tube after years of inactivity. Recommendation: operate it to burn off potential gas buildup and allow the getter to work.
