What grid square is the HL57 operating area?

HL57 is the live DXRadar reference square for the HL57 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of HL57 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 HL57 right now?

HL57 is currently rated POOR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

Sunrise 07:45 UTC

Sunset 19:54 UTC from HL57

From the HL57 operating area, work the 07:45 UTC and 19:54 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses HL57.

Best band now

10m

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

● Best DX Windows from HL57 — the HL57 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from HL57 to each DX region at SFI 105 / Kp 0.67, 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 HL57

A planning heuristic for the local day at HL57, built from sunrise 07:45 UTC, sunset 19:54 UTC, SFI 105, and Kp 0.67. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 07:45 UTC

40m · 30m · 20m

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

Morning

after 07:45 UTC

20m · 15m

Modest SFI — 20m is the daytime workhorse here.

Midday

local noon

15m · 20m

20m and 15m carry the daytime load at this SFI.

Dusk grayline

around 19:54 UTC

20m · 40m

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

Night

after 19:54 UTC

40m · 80m

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

Spots touching HL57 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in HL57, HL58, HL56, HL67, HL47. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate HL57 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.
