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.

The party must have been moved to 80 meters because there were only Walt, Nick and me heard here on 40m this evening.Someday I need to figure out a way to put up an antenna for 80 on my less-than-postage-stamp-sized lot. Helium balloon? See (hear?) you next month.  72 ... Don


Great weather at 60*F a little rain and overcast.  Before the Spartan Sprint I didn't hear much activity on any of the upper bands and 40 was extremely noisy so I stuck to only the 80 meter band filter.  Even on 80 I didn't hear a lot of activity and only worked 3 stations. A few minutes before the end I called CQ and a ?3X? came back when I I sent a ? my battery died...  either good or bad timing.  Thanks to all who participate.  72


K3/10 @ 5W to a 40M extended double Zepp.  2 contacts on 40 and 5 on 80M (1 QRO contact on 40M removed).  Best signals:  40M - K3RLL, 80M - K5MUG.  Nearly half my contacts were named Don!  Gave up early but had fun.


Heard no signals on 20 or 40. 80 was the band of choice. Lots of qrn. At one point I was heard by 20 RBN's across the country. Rig Kwd 590, ant vert. and nvis dipole, rx loop.73 to all - Scott


80m was really thin.  Did not check 40m.   This time I gave up before my batteries did.  KX3 w/500 mAH LiPo Battery Pack running at 5w with K0MBT 3D Printed Mini-Mini Key and Earbuds to a bent 107' EFRW up 20'.   73 - Jody - K3JZD
