SOAPBOX: June 2021 ARS Spartan Sprint


K3/10 @ 5W to a 40M extended double Zepp.  6 QSOs on 20M, 3 on 40 and 1 on 80. 6 states this month. Best signals: 20M - NØTA, 40 and 80M - K4BAI.  Remarkable signal:  K4PQC @ 2W! Gave up after an hour and a half, but still had fun. Holding a good thought for Andy, W5ACM (SK) . . .


4 Qs on 40M. 1 on 20M. Thanks all.


4 on 20m, 6 on 40m. Worked the first 45 minutes. K3, Doublet, GenLog.


Started out on an empty 40m band, wondering where everyone was.  Yep, 20m was open (in and out) and that's where the party was tonight. At last, there is hope for improved propagation in my lifetime!  Thanks for the nice contacts this evening and for the Spartan Sprint .  72 ... Don


Terrible weather here in Bishop, GA with severe lightning storms approaching.  I couldn't hear many stations so I decided to just call CQ and go as long as my battery would last.  It only lasted for one hour and this was OK as I had to shut down my station anyway because of the lightning.  Using a modified Steve Weber design ATS-3B and 160 meter loop at 25'.


Another fun night with the little red radio. I shaved off some ounces and got my station down to 0.606 pounds using a different battery, ear buds and paddle made with some smaller wood.


3 QSOs on 20M; 13 QSOs on 40M; 3 QSOs on 80M.  Only one heard and not worked was WVØH on 20 and I worked Myron on 40. Thanks for all QSOs.  73/72, John, K4BAI.


Set up my mcHF rig for the sprint.  The LiFePO4 battery I use with it outweighs the rig! The contacts were great for the first hour But activity disappeared during the second.  K4PQC was sounding FB with 2 watts! TNX to AB9CA for 2 bands.  Worked 2 on 20, 2 on 80, and the rest on 40.  SRI to the couple stations I couldn't pull out due to QRN. 72, Don


Celebrating my 50th year as an amateur radio operator.


Very frustrating evening. Started on 20M with 5 qsos, then shifted to 40M and 80M. That's where things fell apart. Local noise was high and although I could copy them none of the stations I called heard me. Heard WA9TGT, K4BAI and WVØH on 40M; K4BAI, WVØH and AB9CA on 80M. 73/72, Andy, W4NLT.


40 meter band seemed rather noisy again, all my contacts were made on 40 meters except for 1 which was on 80 meters. I was using my KX2 with a 12v 4000 mAh 12v Lithium-ion battery. Participation in the Spartan Sprint seems pretty low again this month.


Ran the K3 at 5w to the usual wires. This is the first time in a looong time that 20 has been the main band. The band breakdown is 11/9/3 for 20/40/80. Total of 23. The noise seemed to be pretty bad on 40 and 80, made it tough to hear. Was hearing stations on 20 who were east of the Mississippi. Been a while since hearing that. Thanks to all for the Q's. Hope to hear everyone, and a few more, next month. 73 de Dave, AB9CA


Many thanks to the unknown heroic operator who worked so hard to cut through my local QRN - wish I could have completed that contact! Made one contact on 20m, 6 on 40m, and then K4BAI and AB9CA for a second time on 80m. Always enjoy listening to such highly skilled CW operators! 72, Evan - Huntsville, AL

Not many Sprinters on 40m this evening but at least those of us there could space ourselves out easily. (But that's not usually a good sign; is it?)  40m was really up and down here in FL and very strong into New England tonight Big signal was KB1M - a nice change after months of barely copying each other.  72 and thanks for the contacts ... Don


Thunderstorms in GA tonight and QRN very bad on 40 and 80 Worked only VE3EDX on 20, 12 stations including NK6A in CA on 40, and AB9CA on both 40 and 80.  Hope for better conditions next month. Now that we are into summer like conditions, it will pay to start on 20M. 

73/72, John, K4BAI.


Used 40m only.  Seemed like pretty good conditions.  Naked 40m QCX w/500 mAH LiPo Battery Pack running 4w with K0MBT 3D Printed Mini-Mini Key and Earbuds to a 40m dipole.   73 - Jody - K3JZD


I used my usual MTR4B-v2 but decided to exclude my Palm Paddle and larger battery (if you can call my 650mAh LiPo a ‘larger’ battery). I used an 1/8-inch stereo plug for my paddles. I rigged a wooden paddle to it from a hamburger skewer and bent the contacts of the plug to allow for single-lever iambic keying. Very fun to have the rig positioned sideways in front of me.

Here is the run down.

Total Weight: 0.62 pounds (0.112 pounds for Panasonic ear buds, battery and paddle)

Input power: 9v battery (EBL Nickel Metal Hydride)

Output power: 3W at start and 0W at 1 hour into SP; battery died.

Total QSOs: 2 on 40m, KF9NL and VE3EDX

Station fun: 100% - 72, Myron. WVØH


Three contacts on 20, the rest on 40m. Used a QCX for both bands, which caused me to miss some weaker callers. Quite a bit of static crashes on 40m making things tough. Tried 80m but no luck. Vertical on 20, doublet on 40.


K3/10 @ 5W to a 40M extended double Zepp.  Operated only 30 min - a serious electrical storm developed almost overhead at about 0130Z. Closest strike < 200 feet away.  1.5" of (much needed) rain in an hour and a half + some hail. Enjoyed 20 and 40M contacts with NØTA (x2), NK6A, VE3DX and K4BAI but pulled the plug and disconnected everything. Still had fun...


I haven't done this one in a while.  KX3 dialed down to 5 Watts with a modified QRPGuys paddle into a Buddistik on my sister's 4th floor balcony railing in Park Ridge, IL.  Stayed on 40.  Heard no SpartanSprint contesters but a lot of stations on the air.  No answers to my half dozen CQs. A lot of fun and easier than at home in Portland OR. - Russ


Using my KX2 with outboard 12V LifePo4 battery. Antenna 100’ cfzepp. I heard very few stations calling CQ SP, all 4 of my contacts were on 40 meters. Band was very noisy due to storm cell passing through.Hope next month will be better. - Donnie Garrett / WA9TGT


Fun times on 20M and 40M this month. I spent the first 25 minutes of the event prepping the ATS3a. It has been a few months since I last used it. With new batteries and somewhat clean key contacts, it did well. The new vertical is also a great help. Looking forward to more 20M ops next time! - 72 de Andy W5ACM, Houston, Texas.

Thanks all for the QSOs. Running 3W with MTR and 18650 battery with a step-up to 10V. Best DX: NØTA in Colorado. 73, Jim


Worked the first hour on 40m. Band appeared a bit long - worked 11 states. Thanks for the Q's. K3 & doublet.


My house is in the midst of being painted so all antennas, such that they are, are disconnected and dismantled this week.  But knowing how important the Spartan Sprint is, I spent the weekend resetting up an attic doublet with two homebrew loading coils and coax running through the house. It's a terrible antenna but some wise fellow once said "any antenna is better than no antenna".  And much to my surprise and joy, seven patient and skilled ops heard me this evening.  Even RBN was my friend this evening!  Thanks to all on 40m and to the complete staff of A.R.S. for continuing to facilitate this monthly pleasure.  72/73 ... Don


Celebrating my 50th year as an Amateur Radio (Ham) Operator.


Got a late start due to a Zoom meeting running over time. Thought I heard a caller on 20M, but couldn't ID the caller. 40M was quite good with no skip zone, so I was able to work as close as 100M iniside GA, plus AL, and FL and also out to NM and MN.  Thanks for all QSOs.  QSOs by band:  40M: 13.  80M: 5.   80 had some QRN, but it wasn't bad and signals were good. 73/72, John, K4BAI.


RIG, HB-1B = 1.39 LBS. I worked 13 states.


Great weather at 65*F for the Spartan Sprint. Lots of activity for Search and Pounce but only a couple of contacts made calling CQ with only 2W. I did work John - K4BAI on 40 and 80.  Also worked Gil - N2GG in NM for his first Spartan Sprint. A little more weight this time using 2 filters. Thanks to all who participate.  72 - Phil


My inaugural run with my new MTR-4B V2. I used a 650mAh Lipo battery, a Palm paddle and CCrane earbuds running 5W into my 40m Delta Loop at home. I started out on 20m calling away and John, K4BAI return my call but quickly faded. I figured if John’s beam wasn’t making it, that was pretty good indication to head down to 40. I stayed on 40 until about 20 minutes left in the Sprint, handed out 8 QSOs there and switched to 80m and worked Nick, WB5BKL again. As always, thanks to ARS for putting this on and collecting our scores. Much appreciated. 72, Myron, WVØH


First event with brand new KX2 + 35ft wire from 2nd story townhouse bedroom window to corner of garage - sloper pointed East with 25ft counterpoise on bedroom floor. 72, Dick ABØCD


80m only, using my just completed purpose-built QCX-Mini transciever.  I was not plagued with a lot of QSB or QRN this month.  It was more very weak signals from the QRP Spartan Sprint players, and not that many participants using 80m.  Maybe 80m will no longer be usable as we get into the warmer months.   I might have to build some more of the single band QCX-Minis.   Naked 80m QCX-Mini w/500 mAH LiPo Battery Pack running at 4w with KØMBT 3D Printed Mini-Mini Key and Earbuds to a bent 107' EFRW up 20'.   73 - Jody - K3JZD


Back on the air now that I have an antenna again! Started on 20 but no activity found. Went to 40 where most of the action was. Logged 11 on 40 and 4 on 80. Good to hear some new calls along with the more familiar ones! Good to see more activity. Rig was IC-7200 @ 5w. Ant was wire. Thanks for the Q's. Hope to be back next month. Dave, AB9CA


K3/10 @ 5W to a 40M extended double Zepp.  Tried 15 and then 20M. RBN heard me on 20 but apparently no one else.  9 QSOs on 40M and 3 on 80M. Best signals: WV0H and K4BAI respectively. Also doubles with Myron and John. Only 7 states this time.  Did not count one 80M QSO as could not complete the exchange. 80M very noisy here. Had fun.


Enjoyed contacting so many of my favorite Sprint operators! I learn a lot from observing how these skilled operators manage weak signals with grace. A nice surprise was working Ivin, N9IVI (not officially in the event) who was backpacking in Indiana: actually living the Adventure Radio Society ethos!


This was my first Spartan Sprint. I called CQ SP on-and-off for 1.5 hours on 7.023 MHz without a response or hearing another Spartan Sprint station (in the rather wide passband of my little rig).  Still, my call showed up on pskreporter with the station closest to Atlanta being in Wisconsin, so I'm actually pretty happy!


Bands seemed to be a little better than previous months. All my contacts were on 80 & 40 meters. Equipment used was a IC-705, 100ft CF Zepp Antenna, RF Output power was 5 watts. Enjoyed the Sprint, Thank You! Donnie Garrett / WA9TGT


Running the TS-590 at 5 watts, vertical antenna and dipole. Conditions were improved up here. It hit 85 degs in the Twin Cities and a TS blew up all around me. So 40 minutes of fun then the mad dash to disconnect antennas! 72 to all Scott NØAR

So, What's a Spartan Sprint, and How Do I Play?

Spartan Sprints are two-hour gatherings sponsored by the Adventure Radio Society, held the first Monday of every month. The Spartan Sprints have a unique, three-faceted focus. They encourage outdoor operation with backcountry radio gear (if outdoor operation isn't practical, home-based operation is fine). They gather fascinating information about the upper atmosphere, documenting how low power signals can travel long distances. And they encourage the growth of a like-minded community of amateur radio operators who generously share their knowledge and experiences.

Which Bands?

Bands of operation are 80 meters, 40 meters, 20 meters, 15 meters and 10 meters. You may operate any number of bands - your choice. Many Spartan Sprint operators gravitate to the QRP CW calling frequencies on these bands.

Equipment and Antennas

Spartan Sprinters use 5 Watts or less. We encourage you to experiment with 1 Watt or less. You will be surprised at how effective these low levels can be, and how much fun QRPp really is. Similarly, we encourage you to experiment with simple wire antennas. And we encourage Sprinters to use equipment they built from "scratch" - that is, equipment built from schematics.


Exchange RST, SPC (state, province or country) and power output. If you choose to call CQ, use the format "CQ SP," or "CQ QRP TEST." You can give yourself credit for working the same station on a second, third, or fourth band.

What Is the Weight of My Station?

The weight of your station is determined by weighing everything at your operating position up to, but not including, your feedline and antenna. In other words, your rig, key, keyer, antenna tuning unit, battery, headphones, and so on. 

Submit Your Spartan Sprint Log

Please send the following information in an email to:
  • Your call sign
  • Total number of contacts during Sprint
  • The weight of your station (in pounds - includes all gear except antenna and feedline)
  • Soapbox comments about your Sprint experience

Check Out the Spartan Sprint Results

The results of each month's contest appear on the Friday following each month's first-Monday Sprint. They are posted here on this website. You can find results from previous months here, as well.
