My Week in Radio

  • Allstar node being weird
  • saw a great youtube video on APRS bots:
    • MPAD being very versatile for: weather, callsign lookup, location report to email
    • ISS bot that tells you the next pass
  • listened to a couple sweepstakes contacts: to lazy to try to communicate that much exchange QRP SSB
  • built a doublet on a portable operation today:
    • split 6.25M of speaker wire to be a 12.5M-long, center-fed, non-resonant dipole, like my portable EFRW I usually carry.
    • the rest is balanced feed line
    • right to the radio
    • tuned 20M and barely tuned 40M on my X6100
    • 2W FT8 heard in Africa and Europe
    • next try it with a 4:1 or 9:1 balun to match better

Others

  • W1RC, Mike:
    • Elekraft K3S from an estate sale.
      • advanced radio
      • had a K3 that he never used.
      • computer with an RF section
      • will sell the K3
  • KN3I, John:
    • Went to the Father Murgas Event in Scranton
    • signed up for N3FJP and LotW access
    • sweepstakes
    • fixing another ICOM radio
    • 80 meters
  • W8CRW, CR:
    • clearnode is working again
  • KC3RFG, Jim:
    • Got some Aurora photos
  • K3FF, Rene:
    • windy a couple weeks ago, found his amp cutting out for high SWR
      • antenna was arcing to another antenna at high power
  • WA3KFT, John:
    • operating 10M net, got TX, NC, NJ, MA without trying
    • 28435kHz - retired net, 1pm EST
  • KD3BPI, Simon:
    • testing airplane radios for work
  • NA3CW, Chuck:
    • chatting mobile
    • PM/AM net: abysmal geomagnetic conditions
    • computer work: database and labels for a church food distribution effort
  • KC3OOK, Bill:
    • relayed for low-power net controllers in simplex net
  • KC3SQI, Wayne:
    • putting new antennas on the new mast
    • shopping other antennas
  • KC3MAI, Joe:
    • Went to Scranton for 120 Anniversary of Father Murgas event: first overland telegraphy
    • started studying CW
  • AA3LH, Leon:
    • Introduced an ATU to replace a manual tuner
    • connected an antenna directly to the radio
      • found lower SWR than with the switch, maybe needs replaced
  • KB3ZIM, Bob:
    • check out the murgas amateur radio club website for that story
    • will be busier in radio as it gets colder outside
    • wants to get a 160M wire in the air
  • AF3Z, Jim:
    • went to Scranton for the Father Murgas event.
    • met the guy who started HamSCI at U of Scranton: very nice shack for school.

Questions

  • WA3VEE, Ron:
    • what are the types of solar panel installation, and which causes the least RFI for HF?
      • each panel could have micro inverter
      • or they could all run to 1 big inverter
      • read a central inverter may be easier to control RFI.
    • KC3RFG, Jim:
      • neighbor has panels across the street
      • 3 years old
      • no choice: all micro-invertors
    • W8CRW, CR:
      • find an installer who will do 1 large inverter
  • KD3BPI, Simon:
    • What are the pointers and highlights of studying for General?
    • Using another test website to study, something besides hamstudy.
    • AF3Z, Jim:
      • hasn’t tested since 1979
    • WA3VEE, Ron:
      • test sites are “ham cramming”
      • look for “Gordon West study guide”
      • you already know most of it
      • FCC wants to make sure you know it at least once
    • WA3KFT, John:
      • has extra class study guide by gordon west.
      • study guide explains why the correct answer is correct.
    • KC3RFG, Jim:
      • used ham study to pass the test and get started
      • focused on what you need to know for the test
      • learn more later
    • KC3SQI, Wayne:
      • learn the theory
      • to study and get on quicker, aarl has the question pool.
      • go back and get the Gordon West book for reference and learning later
    • KD3BPI, Simon:
      • will find that Gordon West book
  • KC3SQI, Wayne:
    • Looking to step up from windom dipole (used for 4 years). on 10M, it has lots of lobes, so hard to predict results. Looking at a hex beam to put on a rotor on the mast. Considering wind loads for antenna, mast, and rotor. Different ways to mount the rotor: unistrut and thrust bearing. Any experience in strengthening a rotor installation?
    • WA3KFT, John:
      • thrust bearing takes all the vertical weight, so none on the rotor.
      • without a brake, it moves easy enough for winds to turn the mast.
