Picking the Right Band for Spring POTA as Solar Cycle 25 Fades

Picking the Right Band for Spring POTA as Solar Cycle 25 Fades

If your 10-meter POTA activations felt a little quieter this month, you're not imagining things. Solar Cycle 25 peaked back in late 2024 with sunspot numbers north of 200, and we've been on the downslope ever since. The SFI has been hovering in the 130s–140s lately — still decent, but noticeably off from the 160+ averages we got spoiled by last year.

So what does that actually mean for your spring activations? Mostly good news, honestly. But you do need to be smarter about band selection than you were twelve months ago.

The Bands, Ranked for Spring 2026

20 meters (14 MHz) — Still king. This band remains your most reliable daytime option for POTA, and that's not going to change anytime soon. It opens early, stays productive through the afternoon, and reaches both coasts from pretty much anywhere in the continental US. If you're only bringing one antenna to the park, cut it for 20.

40 meters (7 MHz) — Your best friend after 3 PM local. As higher bands fade in the late afternoon, 40 picks up the slack beautifully. It's also your go-to for shorter-range contacts during the day — 300-800 mile skip zone fills in nicely on 40 when 20 is sailing signals right over nearby hunters. A lot of activators forget this: running both 20 and 40 during a single activation can easily double your contact count.

15 meters (21 MHz) — Still works, but check before you commit. Fifteen was absolutely cranking during the cycle peak. Now it's more of a "when it's open, it's great" band. You'll get solid openings on sunny afternoons with SFI above 130, especially for DX into Europe and South America. But don't build your whole activation around it.

10 meters (28 MHz) — The heartbreaker. Ten was the star of 2024 and early 2025. Now? Sporadic openings at best during spring. You might catch some sporadic-E starting in May, but for reliable POTA contacts in April, leave 10 meters for your second or third frequency, not your first.

17 meters (18 MHz) — The sleeper pick. Seriously, 17 doesn't get enough love in the POTA community. It sits right between 15 and 20, catches a lot of the same propagation as 20 but with less competition. If you've got a tuner or a multi-band antenna, try calling CQ on 17 before you default to 20. You might be surprised.

How to Check Before You Head Out

The worst thing you can do is drive 45 minutes to a park, set up your station, and then discover the band you planned on is dead. I used to check the solar numbers on NOAA's site, cross-reference with DXHeat, maybe glance at a cluster — three tabs minimum before I even packed the car.

These days I pull up Hamtrax before I leave the house. Their solar dashboard puts the SFI, K-index, A-index, and band condition forecasts all on one screen with color-coded ratings. Green means go, red means pick a different band. Takes about ten seconds to know what to expect. The thing I actually find most useful, though, is flipping over to the live POTA spots — I can see which bands activators are actually getting contacts on right now, not just what the propagation models predict. Real-world data beats forecasts every time.

Practical Tips for Declining-Cycle Activations

Bring a multi-band antenna. This isn't optional anymore. During the peak, you could throw up a single-band dipole for 10 or 15 and have a great time. Now you need the flexibility to shift bands mid-activation. An end-fed half-wave with a tuner, a linked dipole, or a portable vertical with swap-out elements all work great.

Start on 20, shift to 40. For afternoon activations, begin on 20 meters and ride it until the rate slows. Then switch to 40 for your second wind. This two-band strategy consistently gets me past 44 contacts — the magic number for a "successful" activation that actually feels productive.

Try CW or FT8 if you're struggling on SSB. Weak signal modes punch through when voice can't. FT8 on 15 meters can pull DX contacts that SSB simply won't on a mediocre propagation day. CW on 40 meters at 5 watts will get you contacts that 100 watts of SSB might miss. If you haven't tried digital modes for POTA yet, a declining solar cycle is the perfect excuse to learn.

Time your activations. Band conditions aren't static through the day. The sweet spot for 20 meters is roughly 10 AM to 4 PM local. For 40, it's late afternoon through early evening. Plan your park visit around the bands you want to work, not the other way around.

Don't Panic — It's Still Good Out There

I want to be clear: declining solar cycle does not mean bad conditions. It means different conditions. The bands that work shift a little, the timing matters more, and you need to pay a bit more attention to propagation. But POTA was thriving long before Solar Cycle 25 peaked, and it'll keep thriving on the way down.

If anything, this is when the operators who actually understand propagation start outperforming the ones who just got lucky with 10 meters being wide open. Use the solar data, watch what bands are producing real contacts, and be ready to adapt mid-activation.

I've been tracking all my activations in Hamtrax since last year — the automatic folder organization means each activation gets its own log without me doing anything, and having the solar conditions right next to my spots feed means I'm making smarter band choices before I even leave the house.

See you in the parks. 73.
