WSPR frequencies for every band
WSPR dial frequencies from 160 m to 70 cm, as WSJT-X ships them. WSPR is a beacon mode: you transmit, others decode and report, and you learn where your signal is heard.
WSPR
Dial frequenciesWSPR signals occupy a 200 Hz window centred 1500 Hz above the dial. WSJT-X has no 60m WSPR default and lists 6m WSPR for Regions 2 and 3 only.

A WSPR transmission lasts almost two minutes and carries only a callsign, a locator and the power. Every WSPR signal on a band lives in a 200 Hz window centred 1500 Hz above the dial, so the dial frequency is the whole story: there is no calling or answering.
Decodes go to the WSPRnet database, where you can map who heard you, at what signal-to-noise ratio and when. It is the quickest way to test a new antenna or to see whether a band is open before you call CQ. WSJT-X has no 60 m WSPR default and lists 6 m only for Regions 2 and 3.
The WSPR table has 12 entries, on 160 m, 80 m, 40 m, 30 m, 20 m, 17 m, 15 m, 12 m, 10 m, 6 m, 2 m, and 70 cm.
No entry for 60 m: the source gives none there.
1 of the entries hold only in some ITU regions, as the regions column shows.
Dial frequencies are the USB suppressed-carrier setting of the radio; the signals sit a few hundred hertz to about 3 kHz above. Band plans and national rules prevail.
