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

• KD3EE, John: Seeing a 20kHz-wide band of noise in the 30M band. In SSB it sounds like a flatulent tractor anywhere you tune in it. reminds me of maybe over-the-horizon radar. What might this be, and what other mysteries in signals have you seen and solved?
  • KC3NZT, Harvey:
    • 60M is shared with military, but 30M may also have military.

Questions

• AC3NW, Manny:
  • Considering antennas for HF in his neighborhood.
    • Trying to remain low-profile.
    • Vertical for HF: Hustler 5BTV
    • trapped vertical
  • WA3VEE, Ron:
    • used that antenna previously when he was a kid
    • 190 countries
    • 75m resonator
    • WAS on 75M SSB
    • for CW as well
    • solar cycle 20
    • Russia, China, Australia
    • used raised verticals
    • we’ve used that antenna at the field day site
  • K3FS, Renee:
    • an end-fed wire can be pretty invisible
  • KC3NZT, Harvey:
    • that vertical could be sort of conspicuous
    • an 80m dipole with ladder line would be a great multiband
    • has chosen to an EFHW for his home
  • W1RC, Mike:
    • likes his 130-ft EFRW + tuner for agility
  • AC3NW, Manny:
    • end-fed sounds interesting
• K3FS, Renee:
  • has an older amplifier, Clipperton L
  • runs 4 5072 tubes.
  • does not have a tuned front-end
  • used pi network to match impedence to the amplifier
  • there’s a tuning module that can be inserted to give 50-ohm interface for transceiver.
  • doesn’t have that module
  • would an automatic tuner match the amplifier that’s not tuned?
  • WA3KFT, John:
    • uses a 7300 with that Clipperton L for 10 meters
    • has inserted an MFJ tuner between the transceiver and the amp.
    • built-in tuner may not have enough range
  • WA3VEE, Ron:
    • has no trouble driving the Clipperton L with 7610
    • caution: built a circuit to key it
  • WA3KFT, John:
    • also has a circuit of a transistor driving a relay to key the amplifier
    • DIC relay
  • WA3VEE, Ron:
    • can share keying circuit to be safe
  • KC3OOK, Bill:
    • learning about his Clipperton L
  • WA3VEE, Ron:
    • another word of caution: look at the voltage on the relay.
    • it’s driver at a high voltage, so it runs hot.
    • use an LM317 regulator to bring it down
  • K3FS, Renee:
    • great to see so many Clipperton Ls around.
    • already has some tuners to use
    • thanks for relay advice
    • will use a quiet relay
• KC3OOK, Bill:
  • How would one adapt a new speaker impedance to an old radio that uses higher impedance? matching wattage?
  • WA3VEE, Ron:
    • speakers are pretty forgiving
    • the volume may vary a little
    • large speakers could require more current to move the cone
    • try it and see
  • AF3Z, Jim:
    • 25W speaker doesn’t need 25W, that’s just the max
  • KC3NZT, Harvey:
    • speakers going into clipping is what damages them.
    • sensitivity is rated in dB at 1W at 1M from the speaker
    • pick a speaker that sounds good to you.
    • Liisong speakers are a great option for radios
    • pay attention to how it sounds. a clipping speaker sounds like garbage.
    • 90dB is the benchmark: quite loud.
    • 200-5000Hz is about what we need for SSB
    • find 8ohms or higher
• KD3EMS, Chris:
  • Church is using FRS Retevis radios, Does anyone have any recommendations for ear pieces for extended use?

Questions

• KA3GLI, Dave:
  • Didn’t care for “Coax Shield” to seal connectors. Is there something better?
  • KB3ZIM, Bob:
    • There’s a silicone tape, coax seal, that sticks to itself, and stays in place really well: 9 years.
    • Maybe you had a bad batch of that “Coax Shield” stuff.
    • try a different brand.
    • make sure the coax is clean.
  • W3KZG, Scott:
    • Coax wrap can be an absolute mess to remove.

  • KC3NZT, Harvey:
    • labor is getting expensive: $1000 labor to install $7 part
    • SDR radios, like 7300 is 10 years old, and working well
    • 10 years is probably a good lifespan
    • with labor price, budgeting to buy replacement might be best
    • doesn’t miss old car systems
  • NA3CW, Chuck:
    • they seldom commit suicide, but they sometimes get murdered
    • some new radios promise updates, but never deliver

Questions

• AB3AP, Mike:
  • Winter Field Day sounds like it is 20-25WPM, and that’ll be comfortable. Faster requires lots of extra listens. What are others’ comfortable speeds?
  • W3DIB: 0
  • AF3Z:
    • keyers set to 35wpm, spacing is usually wider.
    • 20-25wpm is more comfortable
    • try to get contact info before the call
  • W3DIB, Greg: N2HM, Bob is amazing to watch
  • KB3ILS, Keith:
    • don’t worry about speed on WFD. people will slow if you need.
    • just skip people who go too fast.
    • working closer to 20wpm will get you more contacts
    • managed first straight key contact at about 6wpm at last field day
    • “we’ll help you copy, just try”
  • WA3KFT, John:
    • passed test with 13wpm for advanced
    • no longer that fast, out of practice
    • taught code in classes
    • first learned it in boy scouts
  • NA3CW, Chuck:
    • slower, took 2 attempts to pass 13wpm
    • 15-18 today
  • KD3EE, John:
    • morsle.fun: 25-30wpm if i can hear it multiple times
    • keyer at 20wpm, but leaving some space
    • I’ll hope to get help copying at field day
  • AF3Z, Jim:
    • flags in boy scouts
    • passed 13wpm in 1967
    • barely passed 20wpm in 1979
    • practicing with a sked qso
    • 35wpm seems impossible, but he’s getting there
    • being retired gives him time to practice
  • W3DIB, Greg:
    • https://lcwo.net/
  • KB3ILS, Keith:
    • use computer programs
    • also just listen to others’ QSOs on 40m
  • WA3VEE, Ron:
    • use a websdr to listen
  • KD3EE, John:
    • ARRL code practice files and podcast
  • KB3ZIM, Bob:
    • hearing signals from south pacific right now on HF
    • practiced and learned at 59 years
    • always intended to use it
    • bought the CW paddle before a transceiver
    • doesn’t want to inconvenience others
    • prosigns are baffling
    • practice sites don’t necessarily demonstrate prosigns
    • seeing dots and dashes slowed us all down
  • KD3EE, John:
    • chase POTA to practice CW
  • KB3ILS, Keith:
    • relayed my message, and recommended spotting from pota.app.
  • AF3Z, Jim:
    • SKCC hangs out on +50khz and events, so good to listen there
    • simple exchanges
    • don’t do CW if you don’t like it.
• KD3APR, Paxton:
  • Seeing some repeaters offering “auto-patch”. How’s that work, and how’s it sound?
  • W3DIB, Greg:
    • Univ Del had an autopatch.
    • you’d need to get permission and get the code to be able to use it.
    • it would place the phone call.
    • it would leave the TX up the whole time the phone was on.
  • WA3VEE, Ron:
    • it’s been years.
    • other person would need to know to say “over” since the carrier stayed up even when remote is transmitting, and on one would otherwise know when the other person stops
    • got to use it once in the 70s to call for road help
  • AF3Z, Jim:
    • needed to remind the phone side that the communication is being transmitted
    • don’t do business.
  • NA3CW, Chuck:
    • you just can’t use the radio for your boss, “under ordrers”.
    • running a business vs doing a transaction.
• KB3ZIM, Bob:
  • Is autopatch still used and offered?
  • WA3VEE, Ron:
    • repeater book lists autopatch as a service on some repeaters
  • W3DIB, Greg:
    • it’s probably easy in the time of VOIP.

My Week in Radio

• seeing more “alternate” FT8 traffic on the waterfall: dxpeditions and contests!
• tempted to replace my old cheap coax with something lower-loss for my 50W VHF to compare.
  • bust out the attenuators and the tinySA or maybe just the little digital power meter I have to measure at the antenna feed point.
• bring a wire and a whip to demo the Nano VNA before or after breakfast.

Questions

• KD3EE, John:
  • I have my 50W mobile radio, home-built YAGI, 75ft cheap coax in a couple connected sections. How should I evaluate this system?
  • WA3VEE, Ron:
    • check that the antenna is matched with the nanoVNA: SWR
    • have people on the repeater talk, so I can point for maximum signal
  • KC3SQI, Wayne:
    • with nanoVNA, calibrate at the nanoVNA, then move calibration load to end and use a through-measurement to see loss in coax.
  • AF3Z, Jim:
    • bury-flex is a good deal
  • KC3SQI, Wayne:
    • if you’re going to an LMR type cable, should good with bury-flex, since the outside doesn’t allow moisture. they use glue between outside braid and the seal. bury-flex will need heated a little to force the crimp end underneath the braid
    • buryflex is available at ham radio outlet.
• KB3ZIM, Bob:
  • What are some 160m antenna options?
  • height and length is a challenge.
  • aiming for an inverted L, but the radials will be a challenge.
  • W3GMS, Joe:
    • 240-foot wire, 60ft in the air, fed by open wire line
    • 3/8-wave would need less radials
      • could be end-fed or inverted L
      • not balanced, so noisy
      • will need a tuner to match
    • 1/4 wave would need extensive radials
  • KC3NZT, Harvey:
    • $150 automatic tuner outside. tunes anything.
