What grid square is the DC77 operating area?

DC77 is the live DXRadar reference square for the DC77 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of DC77 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 DC77 right now?

DC77 is currently rated FAIR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

Sunrise 12:45 UTC

Sunset 01:01 UTC from DC77

From the DC77 operating area, work the 12:45 UTC and 01:01 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses DC77.

Best band now

10m

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

● Best DX Windows from DC77 — the DC77 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from DC77 to each DX region at SFI 118 / Kp 0.33, 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 DC77

A planning heuristic for the local day at DC77, built from sunrise 12:45 UTC, sunset 01:01 UTC, SFI 118, and Kp 0.33. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 12:45 UTC

40m · 30m · 20m

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

Morning

after 12:45 UTC

20m · 15m · 10m

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

Midday

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

Night

Spots touching DC77 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in DC77, DC78, DC76, DC87, DC67. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate DC77 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.
