FSQ on 5 MHz

FSQ is a Fast Simple Qso chat mode, a bit like chatting by SMS or Skype but of course using RF. The FSQCALL protocol was developed by Murray ZL1BPU with significant input from Con ZL2AFP. Murray suggests all the hard work was done by Con 🙂

FSQ is intended for fixed frequency (channelized) operation, with dedicated calling frequencies. It isn’t intended as a ‘tune around to see what you can find’ mode!

Suggested Frequencies

Region 1 (Africa, Europe , Middle East)
80m 3588 kHz USB (sunset to sunrise)
60m *5367.5 kHz USB local day
40m 7044 kHz USB (sunrise to sunset)
30m 10144 kHz USB (local day, DX night)

*suggested UK freq for 5 MHz.

Region 2 (North and South America)
80m 3594 kHz USB (sunset to sunrise)
40m 7104 kHz USB (sunrise to sunset)
30m 10144 kHz USB (local day, DX night)

Region 3 (Australia and Asia)
80m 3580 kHz USB (sunset to sunrise)
40m 7105 kHz USB (sunrise to sunset)
30m 10149 kHz USB (local day, DX night)

You can read more about FSQ and the way it can generate automatic replies from station monitoring the frequency. You will need to understand how the commands work.

To help you get started have a read at the operating guidelines published here. They establish some rules around callsign format being in lower case and what frequencies to try. One option for inter G is to try 5 MHz, put your dial freq on 5367.5 USB and call CQ.

You can download the software on ZL1BPU website, for some reason we have a USA and rest of the world version. I would suggest you select the rest of the world version (unless your in the USA) as for some strange reason they dont both centre the signal as 1500 Hz (centre of the waterfall) if you try and use the USA version and the other station have the rest of the world version you cant operate on the same dial freq.

FSQ was developed by Con Wassilieff ZL2AFP with the assistance of Murray Greenman ZL1BPU. The first QSO took place between these two on 28th November 2014, and the first Alpha executable release was on 17th December 2014. The source code was released with the Beta version 0.23 on 3rd March 2015. The first US version release (V0.24 RC1 by Bob NW8L) was on 29th March 2015. The first full-package public release was by Bob NW8L on 29 April 2015.

A version of fldigi with full FSQ support was released by Dave W1HKJ on 16 July 2015, and includes support for Linux and Mac platforms.

More information on FSQ and fldigi is available online.

The software requires very little setup, just add your callsign (lower case) and locator. You may need to use VOX to key the radio, much depends on your local setup.

Here you can see a screen grab from a chat with G4VLC Peter, G0VPJ John, G4DAX Dave on 5367.5 MHz USB
