What grid square is the CA20 operating area?

CA20 is the live DXRadar reference square for the CA20 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of CA20 for planning propagation.

How do I find my grid square?

Use a Maidenhead grid lookup from your GPS coordinates or street address, then compare that grid with the nearby squares linked on this page. A 4-character grid is enough for most HF planning.

What bands are open in CA20 right now?

CA20 is currently rated POOR. The best bands right now are 20m, 30m, 40m, 60m, 10m, with 20m as the main band to watch first.

Sunrise no sunrise — polar day

Sunset no sunset — polar day from CA20

From the CA20 operating area, work the no sunrise — polar day and no sunset — polar day grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses CA20.

Best band now

20m

Night operation should keep 20m on watch and move to 40m as the path darkens.

● Best DX Windows from CA20 — the CA20 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from CA20 to each DX region at SFI 121 / Kp 3, and a current verdict. "Open now" means a suitable band is scoring well on that path; "Try ~HH:MM" points at the next far-end grayline. Band picks and status are a planning heuristic, not a measurement.

● Band-by-Time Plan for CA20

A planning heuristic for the local day at CA20, built from sunrise no sunrise — polar day, sunset no sunset — polar day, SFI 121, and Kp 3. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around no sunrise — polar day

40m · 30m · 20m

Grayline enhancement — low bands reach long distances as the terminator passes.

Morning

after no sunrise — polar day

20m · 15m · 10m

High bands rising with the sun; check 10m for DX.

Midday

local noon

10m · 15m · 20m

Peak high-band window — 10m and 15m open widest.

Dusk grayline

around no sunset — polar day

20m · 40m

Second grayline peak — 20m holds, then hands off to 40m.

Night

after no sunset — polar day

40m · 80m

Low bands own the darkness — 40m for DX, 80m regional.

Spots touching CA20 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in CA20, CA21, CA20, CA30, CA10. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate CA20 footprint right now. That usually means you should widen the search to the nearest regional hubs below or fall back to 20m/40m for the next operating window.
