What’s in a name?
· PSK stands for Phase Shift Keying
· 31 represents the width of the signal (31.25)
· Occasionally you will see this mode listed as BPSK. The “B” stands for Binary
The PSK QSO:
CQ CQ de [YOURCALL][YOURCALL]
CQ CQ de [YOURCALL][YOURCALL] K
Note: The “K” at the end of your transmission means over or go
[YOURCALL][YOURCALL][YOURCALL] de [THEIRCALL][THEIRCALL][THEIRCALL]
[YOURCALL][YOURCALL][YOURCALL] de [THEIRCALL][THEIRCALL][THEIRCALL] pse K
Note: The “pse” at the end of this call stands for “Please”
“KN” may also be used; this indicates that you only want communication with a specific station.
[THEIRCALL] de [YOURCALL]
Thanks for the call!
RST 599 599 599
QTH is _____, ______
Grid EM29 EM29
My name is yourname, yourname
[THEIRCALL] de [YOURCALL] K
Note: You may also see BTU which stands for “back to you”
At the end of your final transmission use “SK” to send a Silent-Key identifying the end of your QSO
Other common abbreviations:
· DX only /DX – Which means the caller is looking for distant stations
· FB – Fine Business, Which means you copied their transmission
· GN – Good night
· OM – Old Man
Good Amateur Practice:
· Unlike other modes, you do not need to run at full power to transmit PSK, the normal output power is 30-50w. Sometimes less is better, right?
· Your transmissions should not activate the ALC, if so back off your Soundcard output level or gain on your transceiver.
So where can you start:
The table below displays a list of common frequencies where PSK31 can be found. However you can hear PSK crop up all over the bands. Once you have worked PSK for a while you will get used to the tone and can pick it out of the bands just about anywhere.
|70 cm||432.2 MHz|
|33 cm||909 MHz|
There are several Digi-Mode programs to chose from, all with different strengths and weaknesses. Below are some of the most common programs to get you on the air.
Now, get out there and have fun.
