Questions

• AA3LH, Leon:
  • He has a G5RV antenna for traveling with 450ohm ladder line. It connects right to coax. Why doesn’t it need a 4:1 balun? Another similar antenna has the balun.
  • WA3KFT, John:
    • the ladder line is part of the antenna, so it’s the normal feed point.
  • NA3CW, Chuck:
    • G5RV suggested running balanced line the whole way back to the station.
  • AA3LH, Leon:
    • Feeds the G5RV with 50ft of LMR-400 and it works pretty well.
• K3FF, Rene:
  • Wondering about capacitors in harbach rebuild kits having different capacitances for the Clipperton L power supply. Is there concern for in-rush current?
  • WA3KFT, John:
    • has a Clipperton L, hasn’t messed with it.
    • higher capacitance is a benefit
  • WA3VEE, Ron:
    • Sees nothing that limits in-rush current on existing board.
    • sent photos of his restoration process
  • NA3CW, Chuck:
    • designer of the B model says no need to worry about in-rush.
    • wire gauge should be sufficient.
  • W3GMS, Joe:
    • schematic shows no in-rush management, so add it.
    • has some good experience using thermistors for managing in-rush.
    • 2.5-3ohm is sufficient.
• KC3SQI, Wayne:
  • Is anyone familiar with the Hex Beam and the center mount balun? Is it open at the top for mounting another antenna above it?
  • KC3NZT, Harvey:
    • most hex beams he’s seen have been designed to be the top of the mast with a little stub to support the spreaders.
    • people who mounted another antenna above it did it with as stand-off from the tower below extending up through the webbing
  • KC3SQI, Wayne:
    • has the question out to some manufacturers. waiting.
• KD3AIS, Tim:
  • Looking for short antennas for the car that fit in the garage. Fender-mounted on truck. Specs being mostly equal, how does he choose?
  • W3MFB, Mike:
    • short antennas will be quarter wave.
    • longer will be better: half wave.
    • DX Engineering has a “compact antenna” that’s pretty good.
  • KC3NZT, Harvey:
    • Anything close to 17 inches are quarter wave, and 30-some inches is half wave.
    • half wave can look pretty normal on a truck.
    • half wave can be less ground-dependent.
    • try to get as much wire in the air as you can.
  • KC3SQI, Wayne:
    • longer half wave antenna may avoid RFI from car.

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

  • 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.

Portable Doublet

I built a doublet experiment at a park 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

Since the flagpole Yagi fell, and I’m not rushing to put it back up, I figured I’d see if I can get my 2-meter antennas in the tree higher.

I threw the line up over the tree to have it drop down the middle, and I now pull the slim-jim antenna up through the middle of the tree. It’s not the highest antenna, above the ground-plane antenna.

I also took a moment to untangle the halyards and feed lines. I looped the 2 feed lines through a spring clip on the roof line to keep them from slapping around so much.

I’m getting good APRS decodes off the lower antenna, and strong repeater signals on the high antenna, but it doesn’t quite receive the 985 repeater.

My Week in Radio

• upgraded my meshtastic nodes: faster bluetooth communication
• new 3rd party firmware on the Radtel RT-880G
  • nice scanning, HF receive, spectrum analyzer
  • APRS beacon

• W3DIB, Greg:
  • Good to hear about computers for Field Day

Questions

• KC3OOK, Bill:
  • He has new test equipment from Ron, but needs BNC cables for it. What cable/connectors should he get?
  • WA3VEE, Ron:
    • You want 50 ohm cables for radio work.
    • TV would be 75 ohms
    • 6ft BNC-BNC plus some adapters
  • NA3CW, Chuck:
    • Avoid cheap cables: poorly shielded/crimped
    • Only trusted the cables he made
    • RG58 is fine for anything 100W or below.
  • WA3KFT, John:
    • SO-239 with adapter to BNC works fine
    • stranded center conductor will be nice and flexible
  • KC3OOK, Bill:
    • will make some of his own cables
• AA3LH, Leon:
  • Likes dipoles, center-fed with ladder line. Should there be a couple twists in the ladder line?
  • NA3CW, Chuck:
    • twists are recommended to keep it from catching much RFI in receive. it exposes both conductors to the noise, so it balances.
    • good signals on balanced lines are differential
  • AF3Z, Jim:
    • twists also help with wind
    • he has a twist ever 2-3 feet.
  • NA3CW, Chuck:
    • be careful to not cause crossovers
  • AA3LH, Leon:
    • has 25 feet and about 4 twists.
    • it flops in the wind some
• AF3Z, Jim:
  • at field day site, each set of antennas are “coaxial”, so in a line, end-to-end, to give them the same direction, but minimal interaction.
  • W3GMS, Joe:
    • antennas will be orthogonal (perpendicular)
      • 80M will run east-west to transmit north/south
      • 40M will run north-south to transmit east-west

I’ve paid for the Nicsure Patreon to get access to his new firmware for the Radtel RT-880G, and I’ve used his Linux CPS to flash it and load channels.

Having a Linux CPS alone is an amazing enhancement. The UI is not necessarily intuitive compared to other radios, but I’m getting accustomed to it. Most the functions I want from the menu are found by long-pressing the green button, and it shows you the shortcut key you could use. There are also posts about an extended manual that helps a bit, but I still found mismatches.

I have it beaconing APRS and receiving, but it still struggles to get a good decode. The stock firmware shows garbage decodes, but his one just doesn’t show anything for those failures.

It seems to have nice scanning, HF receive, and the spectrum analyzer.

The flagpole mast broke in the wind about 9:05pm EST or so. I captured the destruction on the Wyze camera that watches it. It snapped right above the point it’s tied to the garage. Fortunately, it fell in an OK direction, so it didn’t damage anything around it.

I could try to put it back up with some spare pieces and guy it next time, or I could try the military surplus mast I picked up at a Ham Fest this past summer.

I’ll be contacting the 985 repeater digitally through Allstar for now.

I ran out to Sam Lewis, US-1418, to activate when the rain stopped.

I took a few minutes to setup my normal EFHW running North-South to operate more to the East and West, though I did get a contact to Colombia.

I operated mostly low-power FT8, 1-4W, but mostly 2W. I chased and got 1 CW contact before it started getting cold and dark.
