Not an automated band-opening prediction
How to interpret: Solar flux and Kp are background indicators. They do not confirm 27 MHz DX. Only dated reception reports show what operators say they heard. New reports are manually reviewed and aren't independent proof of reception or contact.

DX activity map
Map displays approved reports within the selected time window where the country name is recognised. Markers show countries, not station coordinates. OpenStreetMap tiles require an internet connection.

10-metre amateur DX spots
From HamQTH's public DX-cluster data. 28 MHz reports are NOT proof of 27 MHz reception. They provide nearby-band activity context.

IONOSPHERIC MEASUREMENTS
Is the MUF high enough for 27 MHz?
For 11m F2 DX, check the MUF(3000 km) map. Values around or above 27 MHz can support long paths, but this is not a guarantee. Maps based on ionosondes are interpolations and may be delayed or stale.
Near-real-time MUF (3000 km)
GIRO ionosonde-derived global map, by KC2G. Check its data timestamp and warnings.

Please report a signal you actually heard or a contact you made. This is not a DX cluster automation or a way to claim a verified QSO. All times UTC.
OTHER LIVE DX SOURCES
Independent 11m cluster
For wider 11m DX reports, consult the RCQSL / CRX live spot tracker. The CRX 11m feed is ready to use when an authorised key is added in the administrator panel. Until then, the local 11m reports and the public 10m indicator work independently. Other cluster websites are linked rather than scraped without permission. UK11Cluster · LOG11DX · DX Jungle.

10m public indicator works without a key. CRX 11m requires your own authorised API key. It is saved server-side in the protected data folder.
