HAM

RADIO

The following amateur radio frequencies are commonly used for transmitting and receiving PSK31 signals. They normally occupy the lower edge of each band's digital modes section. PSK31 operators generally use upper sideband (USB), even on frequencies below 10 MHz where the convention normally calls for lower sideband.

This deviation from the norm is mainly done because:

Signals spread upwards into the digimode section from the "base" frequency

and using QPSK requires both stations to use the same sideband.

PSK31 Frequencies

Frequency Amateur Band

1.838   Mhz           160 meters

3.580   Mhz           80 meters

7.035   Mhz           40 meters (regions 2,3)

7.040   Mhz           40 meters (region 1)

10.142 Mhz           30 meters

14.070 Mhz           20 meters

18.100 Mhz           17 meters

21.080 Mhz           15 meters

24.920 Mhz           12 meters

28.120 Mhz           10 meters

50.290 Mhz           6 meters

 There is no authoritative list, as the frequencies are determined by common convention.

The 20 meter frequency (14.070 Mhz) is very popular with both DX and US hams.
