Questions

• WA3VEE, Ron:
  • Students are using APRS to track balloons they launch.
  • using a kenwood HT and phones to track APRS.
  • suggest maybe a beam for tracking it directly
  • What is the range of APRS?
  • Suggestions for tracking?
  • W3KZG, Scott:
    • check with Corbin, K3HXW.
  • KD3EE, John:
    • it’s packet radio, so relayed by digipeaters
    • bridged to the internet, so reliably visible on aprs.fi
    • btech uv-pro is a great, inexpensive radio.
    • seeing DC to Williamsport to New Jersey on my map here
    • I have a fixed antenna for APRS 30 ft in a tree
• AA3LH, Leon:
  • Un-Un at the end of an EFHW, how do they get away without a counterpoise?
  • WA3KFT, John:
    • Needs a good earth ground to be the other half of the antenna
      • stake, water pipe, etc.
      • need a radiating element and a counterpoise
  • KC3RFG, Jim:
    • started with end-fed antennas
    • if you don’t install a counterpoise, it’ll use the shield of your coax as the other half of your antenna
    • choke the coax before it enters the house or gets to the radio
    • proper counterpoise helps avoid RF on the coax
  • NA3CW, Chuck:
    • he wrote an article on the 985 website
    • not all end-feds are horizontal, any vertical antenna is an end-fed
    • running low power, you don’t need to worry as much about return RF.
    • vertical whips are end-fed
    • horizontal random wire is an end-fed.
    • ground plane or radials of a vertical is a counterpoise
    • person serves as counterpoise on an HT
  • AA3LH, Leon:
    • always uses speaker-wire counterpoises with ham stick verticals
• WA3VEE, Ron:
  • Has anyone interfaced a weather station to NOAA via APRS or via internet connection?
  • W3MOW, Mike:
    • Is this the same integration like Weather Underground?
  • WA3VEE, Ron:
    • Weather Underground and all those other services.
    • Ground Truth Weather
  • W3KZG, Scott:
    • Dylan, K3DZN, has a weather station at the house that’s all linked up.
  • KC3OOK, Bill:
    • Have you bought the Davis View weather station yet
    • It has lots of modules
    • APRS is a module, good for emergency service
    • Can run on a RPi or small computer depending how much you want to do

I achieved 3rd place in QRP class of the 2026 PSKFest with 11 contacts, 2 DXCC, and 8 states for 110 points. Only 4 people had submitted logs for QRP. :)

Upgrade

I upgraded to R1CBU 0.32.2. It tested fine with WSJT-X.

It has a new IF-shift feature to move birdies in the menu, but it was “unavailable” on the old base firmware I was running, so I had to upgrade to Base 1.1.9:

• https://www.radioddity.com/pages/xiegu-download
• write the image to an SD card
• boot it
• let it restart
• apply the base 1.1.9 upgrade from the system / firmware menu on the stock firmware

Upgrading the base to 1.1.9 went OK after figuring out some issues with a bad /dev/sdb device handle on my Linux notebook.

New Features

Now I can “IF Shift” when I find a birdie near or in the passband I’m trying to hear. It binds nicely to the bottom MFK for quick access.

This firmware continues to work for FT8. I tested power output with CW as well, since there was a note about needing to applying an output gain.

It’s nice to see the discrete values from the graphs also on the screen: received signal, TX power, SWR.

I’ve been experimenting for a while with 2 stop bits in flrig to get the initial connection to succeed more often. Sometimes it helps, and sometimes it doesn’t. I was hoping this update may help, but there’s no difference. I’ll go back to 1 stop bit.

    • PR on 6M CW
    • Alaska on 15M CW
• WA3KFT, John:
  • WFD with another club, 75M
    • didn’t hear anyone in the afternoon, all noise
    • early evening it lit up
• KC3OOK, Bill:
  • simplex net
  • welfare net
• NA3CW, Chuck:
  • welcome Al
  • antenna install for WFD with lots of people
  • “how to cut a dipole the second time, every time” worked pretty well
  • used Joe’s tuner with 100W testing
  • PMAM pre-net
• AF3Z, Jim:
  • SKCC month ends on saturday
    • coordinating SKCC ops, had enough of it :)
    • worked 240 contacts with special callsign
  • worked WFD with cornwall station
    • proved total lid
      • operated a Elecraft K3 on 40M
      • heard W3R, but couldn’t get an answer
      • K3 needs VOX enabled for CW, so it wasn’t transmitting
      • quit for the morning
      • realized much later about VOX
• AA3LH, Leon:
  • winter field day at home: 40M and 80M *** Questions
• KD3EE, John:
  • What was the problem with the 80M antennas and that radio that rebooted?
  • How significant is the dipole arrangement (flat vs inverted-v) to multi-station operation?
  • W3KZG, Scott:
    • originally thought it was RF
    • switched radio to AC-DC power supply, and then the radio was fine
    • trailers battery may not have kept up with the severe cold
    • new radio couldn’t tolerate voltage drop, but older radio was ok
    • LiFEPo battery struggles under 30F
    • CW dipole showed high SWR at one spot, still needed to be investigated more
  • WA3VEE, Ron:
    • when the weather is better, Ron will run a complete analysis on each antenna on the site.
    • we can talk inductance and capacitance then
    • there seems to be an RFI problem from a power transformer insulator up there as well
  • KB3ILS, Keith:
    • 80M dipole cut for sideband worked well
    • 40M CW in the corner may need some work
    • 1 beam was pointing at the 80M dipole, so likely caused lots interference
    • it’ll be good to analyze when no one transmitting
    • one 40M dipole may be close to noise.
    • some experimenting to do
    • we still got lots of 40M contacts
  • NA3CW, Chuck:
    • power-line interference has been an ongoing issue
    • Chuck has a small moxon for 137MHz that will be good paired with AM on his HT to search for the noise source
      • worked to find a bad pole in his neighborhood
    • inverted vs flat dipole
      • dipoles end to end have very little radiation off the ends.
      • inverted-v antennas would have seen each other on the ends
      • analyzers work with very low signals, so would have totally been skewed by nearby QRN and TX
  • KB3ILS, Keith:
    • Chuck, let’s build a dipole curtain array for field day.
• W3MFB, Mike:
  • HF vertical can have a ground plane, even in the air or on the ground? They help control common-mode current? Why use them?
  • WA3VEE, Ron:
    • the ground plane is the other half of your antenna.
  • WA3KFT, John:
    • Has the Amtron A99 on a tower without the ground plane kit, but has a TV mast below it on the tower, so may be serving the purpose.
  • W3KZG, Scott:
    • IMAC 2000 antenna, 50 ft in the air without the ground plane kit. The galvanized steel mast underneath it served as the ground.
    • AMTRON 99 came with it, so he installed it. It looks cool.
  • AA3LH, Leon:
    • Used tuned hamsticks in Colorado, and put out lots of radials.
  • KD3EE, John:
    • the computer and radio going wonky (touchpad, USB, etc) always remind me when I need to add radials to my vertical antenna.
  • W3MFB, Mike:
    • With the IMAC, he knows he needs the ground plane kit as it gets higher in the air.
    • His is grounded to a gas pipe, so it seems to work pretty well, and he’s gotten to Australia.
    • Also has lots of coax to absorb it.
    • Has gotten to Australia with it.
• KD3BPI, Simon:
  • He’s planning for antennas on the house, 2 stories, walk-up attic. He has a dormer facing west, and was planning to mount antennas there. Easy to get to them from attic. Can he mount all the antennas on one plate or should he space them out?
    • regional HF (20m) antenna and dual-band 2m/70cm antenna.
  • WA3VEE, Ron:
    • Personally doesn’t like to have antenna on the house, since it draws lightning.
    • How much land?
      • Simon: L-shaped, 1/3 acre, but no trees that are actually his.
    • 40M would be a good horizontal wire for regional NVIS
    • grounding is imperative for lightning protection of the house.
    • those antennas, in size, are very different.
    • wires are easier for HF
  • W3GMS, Joe:
    • the Hustler 5-BTV for 80-10M is a good option
    • he has radio and tuner for Simon
  • W3MFB, Mike:
    • Hustler in the yard would be a good option
    • pin down the feed line and radials with lawn stakes
    • neighbors trees: any limbs over your property could be used to hold up an end fed antenna
    • get the antenna as high as you can get it
  • WA3KFT, John:
    • He has 5 antennas at the top of a tower, like a candlabra.
    • an edger is good for grooving the lawn for wires
  • WA3VEE, Ron:
    • sent link to the Hustler 5-BTV
    • the digital modes are FT8 and PSK31
  • W3KZG, Scott:
    • Has an NMO lip-mount with dual band antenna clamped to the rain gutter of the shop.
  • KC3NZT, Harvey:
    • using a copper pipe j-pole inside in the attic of the garage.
      • should work just fine.
    • an HF antenna in the attic would work fine too
  • WA3VEE, Ron:
    • for new hams and those in HOAs, attic antennas can be effective
  • W8CRW, CR:
    • Why’s the 5-BTV so highly recommended, compared to other variations?
    • WA3VEE, Ron:
      • the 5 walks the line of versatility and size
      • they’re different sizes
  • W3GMS, Joe:
    • a 4-BTV is 4-bands, 5- is 5-band, etc.
  • KA3GLI, David:
    • on the 5-BTV, what auto-tuner is recommended?
    • W3GMS, Joe:
      • LDG RC-1 auto-tuner helps match as you get away from the vertical’s narrow, high-Q, resonant spot.
  • KD3EE, John:
    • remember you can build these HF antennas with some wire and toroids.
• KD3BPI, Simon:
  • How does height affect performance of a vertical: ground vs roof?
  • W3GMS, Joe:
    • wire radials on the ground are easy. detuned by the earth.
    • lots of short radials are best
    • elevated radials will perform better, but will require tuning of radials.
    • random lengths are fine on the ground
  • KC3WRY, Matt:
    • a ground-mounted antenna is easier to tune, instead of up in the air.
    • ground-mounted can always later be moved.
  • WA3KFT, John:
    • worked at an AM radio station.
    • when they moved, they rebuilt all the radials.
      • 60 short and 60 long radials
  • W3GMS, Joe:
    • 8 radials with the 5-BTV at the beach was fine
    • gains aren’t as impressive after the first radials

While driving to winter field day, I heard lots of fldigi/flmsg messages sent and received during a drill on the W3EOC repeater system. They assigned municipalities to each operator to call them for reports.

I found the old AndFlmsg from sourceforge wouldn’t install on modern Android, so I couldn’t immediately decode messages.

I found and installed a new version of AndFlMsg, from a new provider. I’ll be ready to follow along the next time.

  • NA3CW, Chuck:
    • WA3KFT is badly deviated, needed to turn down audio when receiving.
  • AF3Z, Jim:
    • As Chuck said, WA3KFT, John is loud.
    • Can hear everything just fine, no cut-out, so that may be Mike’s rig.

• WA3VEE, Ron:
  • Antennas were cut long, then installed, we tested, then adjusted. What’s the formula for determining the amount to trim?
  • NA3CW, Chuck:
    • SWR guesses were just good guesses.
    • For adjusting the length of the dipole: “tuning your dipole, second time, every time”
    • lots of things affect resonance:
      • height
      • quality of ground
      • insulation
      • wire velocity factor
    • to adjust:
      • measure before you put it up, while long

I purchased a USB adapter to connect my CW paddles (1/8-inch audio plug) to the computer. I can now use Vband on-line chat to practice keying CW with other people.

The adapter simulates Left and Right Ctrl keys with the morse key, and the website interprets that as dits and dahs. It works really well.

I also found Morse Invaders, which is a typing tutor that uses CW: key the word before it hits your city.

Minor Linux Note: I use keyd to remap some keys on my laptop, so be aware how it may mess with the Ctrl Keys.

  • W3KZG, Scott:
    • 11M dipole hanging in a tree, 6ft from the ground: similar to hanging it from the ceiling.
      • split right off the coax, speaker wire
    • just try it
    • try a magmount vertical
    • try it on a balcony
    • near a window: magnetic loop
  • KC3SQI, Wayne:
    • use 11M whip antennas, and trim it
    • wire across the wall
    • work from the balcony
    • drop a piece of wire from a higher floor
    • outside will avoid inside RFI
    • inside can mess with other electronics :)
  • W3KZG, Scott:
    • may have an 11M whip to donate
  • W3QNZ, Joe:
    • recycled a pota antenna made of scrap wire and a cobra head
    • moved it into the attic
  • KD3EE, John:
    • may have a loop antenna to lend
    • run wires down the hallway or the loft
    • use lower power, digital modes, CW, weak signal for results

I updated rpt.conf on my node to enable the 813 DTMF code for making permanent link. The permanent link will try to re-establish itself after a disconnect.

It doesn’t re-establish upon reboot, so a macro is still needed on startup. I updated the existing startup macro to *81353085 after *77 (report).
