PSK /RTTY/ NAVTEX

 

RTTY is still popular and heard on the amateur radio bands on a very regular basis, especially at weekends and during contest periods. There are numerous software packages to choose from. But for me I think the truetty program takes a lot of beating and is the only one I use now. Multipsk again is very good. There are some links near the bottom of the page where you can go directly to the programmer’s site and make your own mind up.

W1AW still sends some of their bulletins using  RTTY / PSK / CW . There are  weather forecasts still sent using teletype from two German coast stations

 

 

FLDIGI is good for  RTTY /PSK, there is a version that  runs on a Raspberry Pi . Below is a screen shot of the windows version ( but the Raspberry Pi version looks the same)

INSTALLING FLDIGI ON A RASPBERRY PI THE EASY WAY

The easiest way to install FLDIGI on a Raspberry Pi is thru the add/remove software function which is part of the operating system. 

 

 

TRUETTY

 

 

 

 

     To control your transmitter you will need an interface of some kind for PTT / Audio out from the computer  to the TCVR microphone / audio into the computer sound card.  check my circuits page out  or you could buy a unit from the internet

 

TRUETTY only installs on windows platform

 

 

 MARINE TELETYPE AND NAVTEX

 

There are a few marine weather stations still sending weather / navigational reports using RTTY

 

  

Both FLDIGI and TRUTTY can be used to decode the RTTY sent by the above weather stations

 

   for a list of current navtex stations and their operating times check here. the majority of tranmissions are on 490 khz (national ) 

or 518 khz ( international ) with some stations now utilising 4.209.6 mhz
