This Week in Ham Radio

• RTTY NA Sprint
• The 2m dipole is flopping around outside on this windy day.
• I heard the ISS pass on scan. That’s always pretty cool.
• I checked into the Simplex Net in Lancaster County I reached the West check-in to Mount Joy with my external antenna and my Quansheng UV-K5 running 5W.

This Week in Ham Radio

• I pulled my j-pole wire into a tree by string for tonight, so it’s outside the house.
• Started testing a longer 71-foot (21.65m) EFRW after months of using the shorter 41-foot EFRW.
  • seems mostly the same, so far.
• ARRL Internationl DX SSB Contest
  • First time using SSB on HF
    • Usually digital modes
    • Not a rag-chewer: here to discuss tech
  • 41-ft random wire
  • 10 watts
  • 42 valid contacts in 37 DXCCs
    • Did hit Russia, but then realized I had tuned too low for my privileges
    • Hit lots of other parts of Europe and South America
  • I was Surprised how well SSB worked
  • I might want a vanity url:
    • Shorter: less room for error
    • People don’t seem to expect “WW”
    • People misheard 2 -> 3
    • Might be easier to type
  • It was nice to chase, since I could pause, relisten until I got the call, etc.

Question about Tuning SSB

During the DX contest, people were tuned all over, not just on full khz. A woman with a higher voice confounded me for a moment as I tried to get her to sound right. I was tuning by 100hz, so some were boomy low, a bit high-pitched, and some were just right. Tuning people a little higher made them easier to read, but that probably makes me lower for them. I tried to keep them as low as I could understand. RIT/XIT might have been useful for longer conversations.

What’s the best practice tuning SSB to hear clearly and tx as clearly as possible?

Setup

The SSB part of the ARRL DX Contest this weekend was a phone contest contacting DX stations only. I used the X6100 running 10W and 41-foot random wire out front window from Mountville.

Exchange

The exchange was:

• Me: 59 <state> (PA, papa alpha)
• Them: 59 <tx power>

Score

My raw score for my 42 contacts was 3 * 42 * 37 = 4662, but I’m sure some logs may be busted, so it’ll be less. I qualified as low power, limited antenna.

I logged directly into QRZ.com. I could take time to understand their entire callsign and then call back.

Problems

I had some problems conveying my call over phone:

• Stations heard my “3” as “2”
• Stations don’t expect “WWC” (“whiskey whiskey charlie”), and hear it as “VWC” (“victor whiskey charlie”).

I made 42 valid contacts, and 4 were outside my privileges as general. I’m not accustomed to thinking about the boundaries in the SSB portion of the bands.

For my future reference, I noted voice ranges for general:

• 3800-4000 khz
• 7175-7300 khz
• 14225-14350 khz
• 21275-21450 khz
• 28300-29700 khz

Question on Tuning SSB

During the contest, people were tuned all over the place and not aligned on 1 or 0.5 khz. I tried to align with them, but sometimes higher was easier to read, but does that shift my voice for them? RIT/XIT may have been the answer for longer contacts, but not for this quick stuff. A woman’s higher voice confounded me a bit as I tried to fine tune.

Conclusion

I had great fun yelling my callsign all weekend, and it’s the most I’ve ever used my microphone.

I assembled a new 71-ft (21.56m) EFRW and strung it up at Emily’s. It’s 5-6ft off the ground. I give it a 17-ft (5.2m) counterpoise and a 9:1 unun as usual. 2:30pm EST, 1W into it gets me midwest to a little bit of Europe on 10m. I’m not making many contacts, so I bumped up to 5W.

The antenna tunes on 40m too just fine. I’m getting a few more contacts there.

As a new strategy, I’m aiming for ALC around 1.0, instead of just below any movement. This allows me to not touch the power slider in WSJT-X quite so much.

A new R1CBU firmware is available for the X6100.

I wrote the image to the micro SD card:

$ sudo dd if=x6100_r1cbu_v0.20.0_sdcard.img bs=1M of=/dev/sdb status=progress

It’s working fine. Auto levels for waterfall and spectrum seems useful, but it still shows the min/max level settings that do nothing while in auto. I had to set up all preferences again, since it comes with a new database on the image.

I did the CQ WPX RTTY contest over the weekend. RTTY is fun and more interactive than FT digital modes.

My Week in Ham Radio

• Chuck’s repairs sound fascinating
  • enough basic electronics from childhood to get to general
• HF radio
  • QRP X6100 with 3rd party firmware - R1CBU
  • Maintainer is flaming out
    • ungrateful complaints
    • unhelpful bug reports
  • Source code is available, so some of us may pick it up
  • UI is an app running on a small embedded linux computer
• Flashed new firmware onto my Quansheng UV-K5 HT
• Restrung a random wire
  • From a steep sloper into a tree in front yard to flat horizontal to the shed in the backyard.
  • Patterns in FT8 contacts look a little different
• Learning CW
  • Morse machine
  • All 40 characters they quiz: Koch method
  • Try the feel with a 3d-printed iambic key
  • Next try a different character set: cwops
  • Next more traditional copying exercises

Question

• Often rebuilding and testing antennas
  • On HF, I can test with FT8 and pskreporter
  • See effect of my changes and maybe more propagation conditions
  • For VHF, how variable are the conditions?
  • On the fringe of accessing 985.
  • Slight repositions with unintuitive results
  • What conditions affect propagation to a repeater like this one?
  • What can I measure?
• Requirements for the Scout badge in radio?

ARRL/FCC/ARCC in Harrisburg

KA3TKW and the 21 repeater group hosted a lunch with representatives from the ARRL, the FCC, and the ARCC.

POTA

I stopped at State Game Land 246 near Middletown to activate on 10m FT8/FT4.

I used 2 different antennas: - initially used Grabil whip fully extended, shorted coil, w/ tuner - 12.5m EFRW thrown into a tree Both antennas seemed to perform similarly. I was skipping far: lots of contacts came from Oregon, Washington, and I even got Alaska.

Clipperton DX

Later that day, I also contacted the Clipperton DX station, TX5S, on 40m via FT8
