PSK31 OPERATIONAL FREQUENCIES
Operational international and regional PSK31 frequencies.

BPSK31, BPSK63, BPSK125 and QPSK31 Common Frequencies

Note that all channels use the upper sideband.

Amateur Band Frequency Comment
160 meters 1.838 MHz Proposed frequencies for PSK31 Recorded activity (mostly USA )
1.840 MHz Recorded activity (mostly European)
80 meters 3.580 MHz Proposed frequencies for PSK31 and all recorded activity
40 meters 7.035 MHz Proposed frequencies for PSK31 in regions 1 and 3. No reported activity
7.038 MHz All recorded activity
7.080 MHz Proposed frequencies for PSK31 in region 2. No reported activity
30 meters 10.140 MHz Most recorded activity
10.142 MHz Proposed frequencies for PSK31 with some reported activity
20 meters 14.070 MHz Proposed frequencies for PSK31 and all recorded activity
17 meters 18.100 MHz Proposed frequencies for PSK31 and all recorded activity
15 meters 21.070 MHz Near all recorded activity
21.080 MHz Proposed frequencies for PSK31. No reported activity
12 meters 24.920 MHz Proposed frequencies for PSK31 and all recorded activity
10 meters 28.120 MHz Proposed frequencies for PSK31 and all recorded activity
6 meters 50.250 MHz Recorded activity (Mostly European)
50.290 MHz Recorded activity (Mostly USA )

With many internet sites providing conflicting operating frequency information for PSK31 and its variants the above table has been prepared based on proposed frequencies presented at the official PSK31 web site http://aintel.bi.ehu.es/psk31.html and review of the Radio DX Summit database http://www.dxsummit.fi/Search.aspx  presented by Arkala OH8X DX sports station http://www.radioarcala.com/  

Frequencies that represent the stand out operational activity are shown in bold.  

The proposed frequencies for PSK31 and recorded activity in the above table for the 160 and 80m bands is inconsistent with Australian band plan for these frequencies. The Australian band plan for the 160m band has the frequency range of 1800 - 1810kHz and the 80m band has the frequency range of 3620 - 3640kHz assigned for digital modes including PSK31. For more details refer to the Wireless Institute of Australia. http://www.wia.org.au/
