Just a brief report regarding the RST entry in the ARRL DX Contest. It was a quick and minimal setup, but complete enough to have some fun. Bill N7DZ, Richard K7NSW, and Matt KC9UHI all invested some hours and effort into the event. We put up the 3 element 10m beam built by Lloyd K7NX (now SK), and for the other bands mostly used Ken's Butternut vertical that has been (semi-)permanently erected north of the barn. It was oh-so-clear what a distinctive advantage the beam is, so we're looking forward to the possibility of a tri-band beam up on a tower (both also donated by Lloyd K7NX) for ongoing big(er) gun performance in contests.
Anyway, we had some fun. Richard and Bill set up on Friday and started operating at 0000z (5pm local) that evening continuing until the good DX bands were gone around 8:30 pm. Our antenna is not adequate to work effectively outside of North America on 80 and 40, and US/CA stations cannot work each other in this contest. We resumed Saturday morning and operated more or less all day, though there was some local AF band rag chew some of the time. We started up again Sunday morning, joined by Matt KC9UHI, and operated until around 3:30pm, quitting early because 10m was pretty much cleaned up and the other bands were just not enough fun. And some of us were tired.
We worked 48 DXCC entities, 65% on 10m, and 6 continents, 40% South America. Some pretty graphs and a map are attached below.
Thanks to Bill, Richard, and Matt for making it happen.
2026-02-24 to 03-03 RST Support of ARRL WAS250
RST participated in the ARRL Worked All States 250 event, operating as W1AW/7 on an RST Club station at the Yuma Hamfest and also at RST member home QTH locations. We did our part well. 13 ops from RST membership and 5 more from other clubs around the state put a lot of RF in the sky day and night for 7 days. Collectively we logged just under almost 4000 contacts in every state and almost every province, as well as 60 DX entities. We used every HF band on CW, SSB, and FT8, plus a little bit on 2m FM.
Ops from RST: AD6T, AI7AZ, K7GPS, K7NSW, KC9UHI, KK7MBX, KK7VLU, KK7WBH, N7DZ, N7NBV, N7OMI, W7RFL, W7VIX
Ops from other clubs: AA1SQ, N7BBQ, N7VBN, W7JET, W7YBY
Thanks to Bill, N7DZ, for AZ section coordination and Scheduler tool support.

Use this link to see if you're in the log. If you're not and you think you should be, contact the CASE helpdesk (helpdesk@k7rst.net) to check for maybe a typo or something on our end that might still confirm your QSO.

Including a donation to help support these events and defray costs will be greatly appreciated. The suggested amount is $2. Checks can be made to Radio Society of Tucson.
