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.
