FSQ in favour of winlink.

After testing both FSQ and WINLINK(winmore,ardop,vara)  modes I have come to the conclusion that  FSQ , for internal emcom without the internet ,meets our needs in a more cost effective way rather  than winlink as each station in the latter system needs an expensive pactor modem for full mesh networking .We can keep winlink as the backup option for P2P communication as in this configuration no pactor modem is needed.

FSQ tests with Australia VK6YM/3B8DO have been successful and we now need to pursue local tests under NVIS scenarios.

Main features of FSQ

• It has been developed with NVIS emcom working in mind.
• It can perform well under very poor S/N conditions nearly at par with wspr.
• It can easily be configured without much hassle.
• By default it works full mesh and can easily be used  in relay mode as well .
• It has chat mode capability.
• It can be used to send text file,spreadsheets in cvs form,pictures,standard Arrl,Iaru,Red Cross forms and radiograms
• Its a low power mode ,thus can easily be fed  with battery and/or solar  power  and can be deployed using QRP transceivers.
• It works both for HF SSB and VHF/UHF FM.
• It has selective calling capability with extra features ,call a friend by call sign,check if your friend's equipment is operating,check your signal report,leave a message ,send files even when your friend is not around.
• It uses an MFSK system of 33 tones,operating at a maximum of nearly 6 baud.
• It provides nearly 60 words per minute.
• Its overall BW is 300 HZ meeting the ITU-R SM.1138 assessment method ,its ITU emission designator is 300HF1B,but the filter bandwidth per tone is only about 3 HZ.
• The centre of tone transmission is 1.5Khz above the radio dial frequency and the tones range from 1.35 to 1.65 Khz.
• It has very low latency-the first letter prints within 200ms of the start of reception.
• It operates in directed mode with tree levels of priority                                                               

Highest priority is manual sending(when the operator listens to the channel)      

The second level is automated responses.                                                                           The lowest level is sounding(automatic ID)
