If any, humans are skilled at decoding RTTY signals in their head, so hardware The Mark signal depending on whether the radio is in LSB or USB mode. Therefore, either the higher or lower audio tone will be The higher audio tone on one’s headphones will be the lower RF frequency if the This is how spots should be expressed, for example. The standard for specifying an RTTY frequency is to use the Mark
The higherįrequency RF carrier is called “Mark” and the lower one is called “Space.” The MarkĪnd Space are often referred to as “tones” because they are two audio tones in The “shift” and is commonly 170 Hz in almost all amateur RTTY today. Two RF carriers have a fixed frequency difference between them. The two carriers are exactly symmetrical and therefore The RTTY signal itself consists of two RF carriers that are switched on and It helps to have a clear picture in one’s mind of how the mode works in order to solve the inevitable configuration issues that are frequently encountered, even by experienced RTTY operators. Just following instructions is often not successful. Light blue text has been decoded by 2Tone:Getting started in the RTTY mode can be confusing and frustrating. + In this screen shot, the yellow text has been decoded by MMTTY, and Using 2Tone, and using one of the following: + WinWarbler can decode a RTTY signal 3 ways simultaneously: using Other DXLab components provide transceiver control, logging, propagation prediction, and active station analysis. WinWarbler includes a macro capability and substitution commands. Includes both the MMTTY and 2Tone engines and uses both for RTTY decoding. + WinWarbler, the digital mode component of the freeware DXLab Suite, + The above functionality under Windows 7, 8, 10, and 11. + In this screen shot, the yellow text has been decoded by MMTTY, and the light blue text has been decoded by 2Tone: + WinWarbler can decode a RTTY signal 3 ways simultaneously: using MMTTY, using 2Tone, and using one of the following: + WinWarbler, the digital mode component of the freeware DXLab Suite, includes both the MMTTY and 2Tone engines and uses both for RTTY decoding. MMTTY on the other hand does have rudimentary logging, macros, and radio transceiver controls although as a stand-alone RTTY system, it lacks many of the features found in a dedicated contesting program.
2Tone is a decoding "engine" that requires logging software to provide logging, dupe checking, macros, and the other tools needed to manage the radio transceiver and computer system(s).
