No additional hardware is required you need only a receiver and computer with a sound card.
Rtty decoders software#
Software also can automatically save NOAA Weather Radio SAME voice messages (NWR SAME) and them digital headers. It can decode GMDSS DSC (HF and VHF) messages. Transmitted in RTTY, NAVTEX, PACTOR-1 FEC and HF-FAX (WEFAX) modes on longwave and shortwave bands. Simple software to handle devices connected to LPT portĪ program to receive weather reports, navigational warnings and weather charts A tool for monitoring popular web-cluster service from OH9W/OH2AQ Radio Club

Uses the same lead already used for other digital modes and for DVK.Weather messages decoder - RTTY, NAVTEX, PACTOR-1 FEC, WEFAX (HF-FAX), NWR SAME softwareĬluster monitor. There are several advantages to using DOOK: No potential for timing jitter (Windows is not a real time operating system), transmit signal will be more sociable to your fellow contesters (narrower bandwidth), auto netting of TX frequency to received frequency and lower processor overhead. My recommendation is to use a variant of AFSK and that is DOOK. I do not recommend the use of FSK but 2Tone will do this with lower processor overhead than MMTTY with EXTFSK. Then you will be using 2Tone for transmit.

Use 2Tone for the main DI window and MMTTY as an auxiliary RX window. It is also more efficiently programmed than MMTTY which is why it uses so little processor resource. Thus saturation of an individual processor may show a slightly higher figure than 12.5%.ĢTone uses a multi-threaded approach that can use multiple processors at the same time.
Rtty decoders windows#
This is somewhat simplified as Windows applications will also make use of Windows drivers, communication, etc which will probably run on a different processor. In my case it will saturate CPU capacity when it is running at 1/8 th of total CPU capacity or 12.5%. One thread software can only ever run on 1 processor at a time. A thread is what the operating system allocates processor resources to. Software can be written so it runs all on one thread. You will have a CPU that does something similar. In hardware it is 4 CPUs with 8 instruction/data caches, which from the software point of view means it is running 8 processors. My AMD FX8350 has effectively 8 processors. The modern processor is not a processor but a set of processors in one IC. However, there is some further information you need to know about processors and software.
Rtty decoders download#
2Tone is available for download from 2Tone Downloads Page – and do read the instructions. Running three 2Tone at the same time the total CPU <2%.
Rtty decoders windows 10#
I am running an 8 year old PC Windows 10 with a FX8350 CPU (not overclocked), 24GB and SSD. I have never measured FLdigi as only ever use it occasionally on PSK for a local UK contest. In my testing 2Tone uses less CPU than MMTTY and both on my PC are <1%. You also might like to use Resource Monitor (windows key and type Resource Monitor). You can also identify internal Windows processes like search indexing. Using this you can get at a lot more data and shows CPU and Memory used by every process running on your PC.

I suggest you download a better application and that is Process Explorer available here Process Explorer - Windows Sysinternals | Microsoft Docs I guess most people use Task Manager to look at process/memory/disk loading.
