Announcements / Comments

Question #197 for conversation: How do you deal with noise (and reducing it)?

(If interested in submitting a weekly question, email n5zkf@arrl.net)

Bill Rose (K5WTR)

• Hurricane Watch Net
  • 14.325 MHz LSB (daytime)
  • 7.268 MHz LSB (nighttime)
  • Milton expected to make landfall tomorrow

Lorna Flansburg (KI5FIZ)

• Robertson County ARES meeting this weekend:
  • 2024-10-12 09:30
  • Franklin Fire Station on Glass St
  • We’ll discuss programming radios
  • J-Pole antenna group build

Matt Robinson (W5XMR)

• Fighting noise on HF from solar array/controllers
  • Ferrite chokes from Palomar Engineers
  • Significantly reduced noise

Travis Scott (KI5TMS)

• I have noise on 2 m coming from a new-ish computer’s power supply
• KG5SDF:
  • I’ve dealt with this before, especially stopping it at the device itself
  • Make sure openings on the device itself are as small as possible
    • You want to create a Faraday cage around the electronics inside
  • Put ferrite chokes on everything that goes in and out of device
    • As many turns as possible
  • Maybe after-meeting presentation?

Robert Carter (NC5R)

• Note on Palomar Engineers
  • Attended presentation from Bob on noise about a year ago
  • Not all ferrite beads are created equally
    • Inexpensive ones on Amazon may not actually cancel noise on the desired frequency
    • Make sure you’re getting the right ones: contact them first!

Matthew Barry (KG5LYE)

• Atmospheric audio noise reduction:
  • Pass Band Filters - cut out high and low
  • Noise Reducer - attempt to reduce white noise
  • Noise Blanker - cut out pulse-type interference
  • Notch Filter - reduce “whistle” noise on a single frequency
  • Attenuation / Pre-amp - reduce or boost of signal prior to filtering
• Check the documentation for your radio!

Jonathan Graham (KD5GG)

• Icom IC-7610
• Filtering systems on modern radios are indeed advanced!

Phil Gates (N5ZKF)

• Report from Belton Ham Expo
  • Saw a lot of familiar faces
  • Lots of fun and interesting equipment for sale
• Noise reduction:
  • Phasing noise reduction unit that operates at RF level
  • Two antennas: one from signal, another just for noise
  • By adjusting the phase of the noise antenna’s signal, it can cancel out localized noise

Buy / Sell

Vic Pears (KX8V)

• Looking for signal report on a different radio
  • N5ZKF: Signal is great, but mic gain might be a little high

Information Exchange

Jonathan Graham (KD5GG)

• 10 m has been open in the afternoon lately
  • Contacted someone in Quebec using AM

Matt Robinson (W5XMR)

• Need help fixing MFJ antenna analyzer
  • N5ZKF: Might try calling up MFJ
