• AF3Z, Jim: When is the voltage rating on a fuse important? 20A, 250V vs 20A, 35V?
  • KC3RFG, Jim:
    • the voltage rating is the max at which it’ll properly react when it opens. If voltage rating isn’t high enough, it might not melt far enough and still be able to arc at the higher voltage.
  • NA3CW, Chuck:
    • it may have more physical features like casing material, spring loading to break the connection more, or interrupting current quickly.
  • WA3VEE, Ron: Look for PDF called “Fuseology”.
• WA3VEE, Ron: What do we tell new HAMs?
  • WA3VEE, Ron: HT is pretty useless.
  • KC3RFG, Jim: Resist the urge to buy, but collect lots of info before making too many decisions.

My Week in Radio

• Monitoring some technical discussions
  • tips on satellite repeaters, including listening duplex
  • some radios have talk-around feature, which I’ve only done accidentally when misconfiguring the radio to talk on the repeater output
• FT Challenge over the weekend
  • lots of activity on FT4, FT8, and subbands outside the usual
  • found wsjtx-improved available on my Debian machine:
    • better colors, location labels, and filters
• Learning obvious things about AllStar last week:
  • my node is simplex, so while the net is transmitting, I can’t throw any DTMF at the node to control it
  • minor delay resulted in lots of missed prefixes

News From Others

• W8CRW, CR: setting up for 10m
• KC3SCY, Luke: doing some good work on 10m
• KC3SQI, Wayne: POTA and 10m
• AF3Z, Jim:

Questions

• KC3TMZ, Matt: Looking to upgrade the coax run through a window. Should he get an MFJ passthrough or better recommendations?

  • a couple people have some homebrew panels like the MFJ
  • some have the MFJ panel
  • others suggest passing a barrel adapter through the wall
  • KC3WWC, John: there’s thin coax and flat coax for the purpose

• KC3SQI, Wayne: The battery for the radio’s memory only lasts a couple weeks, so he runs a 12V wall wart to keep it powered, but also has a 35-amp 13.8V supply he wants to use. He isolates them with relays, but is there a solar controller way to switch. Blocking diodes? Recommendations?

  • WA3KFT, John: his 7300 doesn’t have that problem. He uses a 12V bus on the desk. His 12V bus is powered by AC power supply on one side, and a 12V battery on the other side. so there’s always power. A blocking diode would need to be 30Amp.
  • KC3RFG, Jim: The manual says power it a couple hours at least monthly to maintain that battery which holds clock and settings. Memories are on the SD card.

My Week in Radio

    • other danger: if you are always connected, someone else could link to you and cross-link.
      • prevent other nodes from linking to me.
      • disallow every other nodes
    • computer security:
      • keep the node up-to-date and secured.

• KC3RFG, Jim: When you setup a station and all the gadgets in the RF chain, where does a wattmeter prefer to be?
  • NA3CW, Chuck:
    • it should be between transmitter and tuner, so you can tell when the tuner is right
    • sounds like bad cable or other installation problems?
    • RF getting back through the chain?
  • KC3RFG will check that jumpers are good
• W3DIB, Greg: On RF now, impressions of the NanoVNA?
  • W3QP, Tim:
    • 100% worth the money
    • depends on use-case
    • needs calibration all the time
    • can be fragile
    • great for building ununs, etc.
    • dedicated VNA can be much more convenient

Questions

• W3QP, Tim: Follow up on battery measurements for the TSA, Watt-hours instead of Amp-hours.
  • bigger batteries have bigger thermal events.
  • Wh is the amount of potential power.
  • Wh doesn’t require doing the math to consider voltage in combo with Ah.
  • 18Ah at 12V.
  • The nominal voltage for the cells is less.
  • Expected usable volts are even less, so Wh is less than just V*A.
  • Nominal voltage can be different across different battery chemistries.
  • Nominal voltage may not be obvious.
  • 11.1 Nominal voltage might be 12.6V at peak charge.
  • Volts and Amps are important for application, but Watt-hours is better overall for capacity.
• AF3Z, Jim:
  • tinkering with Hartley oscillator: mica capacitors, ceramic capacitors, what’s the difference of all the different capacitors?
    • WA3KFT, John:
      • ratings: capacitance, voltage.
      • The “dry electrolytic” is a paste, not oil.
      • main purpose is filtering AC converted to DC.
      • filtering some frequencies
      • ceramic capacitors are pretty stable, until overheated.
      • mica capacitors are small capacitances, pF. used for frequency stablizing.

        • used for audio.
      • paper capacitor
      • dielectric is anything that separates the plates.
      • air capacitors
    • W3QP, Tim:
      • silver mica are maybe lower loss than ceramic
      • multi-layer capacitors for higher currents
    • W3DIB, Greg:
      • negatives of certain capacitors:
        • some dielectrics leak
        • tantalums can dead-short, like in a power supply.
      • saw a cool video of people building filters for cheap radios in places with heavy RF to keep them working better.
    • WA3VEE, Ron:
      • they leak when they get overheated.
      • leads to the plate have a little resistance so generate heat.
      • capacitor can have a vent that leaks under pressure.
    • NA3CW, Chuck:

My Week in Radio

• R1CBU 0.26.0 firmware for my X6100
  • I continue to maintain a fork of the code that modifies the database to show boundaries of US privileges and recommended usage.

Questions

• W3MFB, Mike: increased tower height, switched to 60ft of new coax. 35W 1.9:1 SWR, so worse than it was before. UHF is bad too. Checked it with NanoVNA. Seeing 1.3:1 SWR. Trying an analog SWR meter. Using Yaesu 991A. Showing 2:1 SWR. SWR goes up with different power.
  • NA3CW, Chuck: Test the tester. SWR shouldn’t change with power. Could be something heating.
  • W3QP, Tim: He does see different SWR at higher power due to reflections from his car. Shorter coax is better, but stay away from quarter wavelengths.
  • W3JAM, Jeff: Test the tester. Hearing him fine on the input, so it’s good.
  • AF3Z, Jim: RF, common mode current, into the meter can cause erratic behavior.
  • NA3CW, Chuck: RF on outside of the feed line is sometimes hard to avoid, and can cause reading issues. Grabbing line at different places will cause readings to change.
  • W3QP, Tim: Some antennas recommend at least a turn of cable at the antenna to choke.
  • KC3OOK, Bill: 1.2 to 1.3 is a 0.9% loss.
  • W8CRW, CR: is that antenna tune-able.
  • W3MFB, Mike: may try ferrite beads at a height he can reach.
• W3MOW, Mike: Looking at Electric Vehicles. Who knows a reputable electrician to run power? Drop him the email you find on QRZ.
• KC3TMZ, Matt: Getting noise with random wire on G90. 71ft 9:1 wire. How does one run the counterpoise?
  • KC3MFB, Mike: 17 ft, opposite direction, if at all.
  • KC3RFG, Jim:
    • try different places.
    • choke at the radio, especially if you don’t
    • run a counterpoise
  • W3QP, Tim:
    • There is always a counterpoise, so provide one so you can control it.
    • Number of turns or number of beads will be effective at different frequencies.
  • NA3CW, Chuck: There’s an article on 985 website.
  • KC3NZT, Harvey:
    • The further from a balanced antenna, the more it’ll force a counterpoise, and that means your coax, so changes around your antenna (body) can change things as well.
    • Run the counterpoise opposite a sloper or flat topper,
    • you can get some gain in the direction of the counterpoise.
  • KC3TMZ, Matt: Propagation to light/dark places?
  • W3MFB, Mike: wire runs NE-SW, and it doesn’t matter for direction too much.
  • KC3NZT, Harvey: Do you hear them? How do you know you’re not getting to them?
    • Can hear them, but they don’t hear him. Did manage Belarus once.
    • Do they have other stations calling them? Is it a pile-up?
    • He’s getting beat for only 20W.
    • Don’t get discouraged. It takes some technique.
  • W3MFB, Mike: Don’t worry about 20W. Don’t call QRP.
  • W3QP, Tim: Operates a lot of 10W. Propagation depends on radiation pattern. EFRW can have weird patterns with spiky lobes.
  • KC3TMZ, Matt: lots to learn, will take a recording from Ron.
• KC3WWC: Headed to Hawaii for a couple weeks and taking radios for all bands. What should I expect/try while traveling?
  • W3QP, Tim:
    • SOTA from volcanos!
    • salt water will give a great boost for DX.
    • lots of asia
• WA3VEE, Ron: the virtues of broadcastify

My week in Radio

• I saw aurora for the first time, and I got some nice photos.
• I visited K3IR tower sight in Mount Joy during PA QSO party
  • I listened to people contesting, but didn’t participate.
• TYT TH-9800: 50W into the tape measure yagi, tried it on the roundtable, still have work to do
• I threw my main 71-foot EFRW higher into another tree.
• I watched my flagpole and yagi in the wind
  • walked it down while I had a kid here to help
  • scoping a new location for it as a tilt-up attached to the house
  • collecting pieces for some experiments in engineering

Questions

• W8CRW, CR:
  • National Electronics Museum is hosting a class for general license.
  • How far from the mast should a vertical yagi antenna be installed?
  • Can it be installed 45-degrees to be used for both horizontal and vertical?
    • WA3VEE, Ron: some have had success at 45 degrees for satellites.
    • KC3SQI, Wayne: 45-degree will lose you 1.5dB
• WA3VEE, Ron: what is the ideal thickness for a bus-bar to which you’re mounting a lightning arrester.
  • KC3RFG, Jim:
    • 1/4-inch minimum. thicker won’t hurt anything.
    • mechanically strong (bolted) instead of soldered
    • woven ground strap is best, but 6AWG stranded is good.
  • NA3CW, Chuck:
    • avoid inductance, so use strap or bar, not wire
    • no right angles, no coils, no spirals
• KC3RFG, Jim: Hearing ignition noise on HF on battery or on truck power. How best can one eliminate that noise?
  • KC3SQI, Wayne: Remove the mast from the coax and see if you still have the noise. If it’s still there, then it’s coming from power cables. Try a better ground directly to the battery. On vehicles that rust, bolts don’t ground so well after a while, so then you get lots of grounds connecting back through the antenna.
  • KC3KZB, Aaron: go for a short ground, and keep ground wire away from ignition wires
• KC3SQI, Wayne: What’s the mechanical strength for 1.5-inch conduit?
  • WA3VEE, Ron: See Ugly’s Electrical Reference.
  • KC3RFG, Jim: that’s right.
• KC3WWC. John: I like that I can build my transformers and cut, measure, and test wire antennas, Is it practical to build, iterate, expand a homebrew yagi?
  • NA3CW, Chuck:
    • blatant plagarism: they’ve been around for a long time.
    • modeling programs, manuals, existing antennas.
    • different goals: gain, bandwidth, front-to-back ratio examples in the antenna book
    • software
    • moxon antenna: 2 element yagi with bent ends, massive front-to-back ratio
      • great for direction-finding: forward to get in the neighborhood, then reverse to find the null where it disappears
      • not much gain though
• W8CRW, CR: Is there a program for windows to map out a computer network?
  • W3DIB, Greg:
    • there are lots of tools to probe and fingerprint machines to try to disclose the host OS.
    • also ping, angryping, etc.

My Week in Radio

• I saw some antennas at the Ham Fest, but I couldn’t bring myself to buy any. I’ll build.
• I passed extra at the Ham Fest
