If transmitting via [[AFSKFSK|AFSK]], setup the [[AudioConnections|Transceiver-to-Soundcard Audio connection and select the soundcard used for transmission]]; if transmitting via [[AFSKFSK|FSK]], setup the [[FSKConnection| FSK connection]]. 1. Setup the [[PTTMechanism| Transceiver-to-PC PTT (reception-transmission switching) connection]] 1. [[ConfigureRTTY| Configure WinWarbler for RTTY Operation]] 1. Configure your transceiver a. if [[TransceiverControl| Commander]] isn't running and you're transmitting via [[AFSKFSK|AFSK]], set your transceiver's mode to ''LSB'' a. if [[TransceiverControl| Commander]] isn't running and you're transmitting via [[AFSKFSK|FSK]], set your transceiver's mode as shown in this [[FSKConnection| table]] a. set your transceiver frequency to an open RTTY band ||80m||3,590 kHz|| ||40m||7,040 kHz|| ||30m||10,140 kHz|| ||20m||14,080 kHz|| ||17m||18,105 kHz|| ||15m||21,080 kHz|| ||12m||24,920 kHz|| ||10m||28,080 kHz|| a. disable compression a. disable all receiver filtering (re-visit this later when operating on a crowded band) 1.

With its '''Operating Mode''' panel set to ''RTTY'', !WinWarbler's Main window provides a Waterfall or Spectrum display, and one or two '''Receive Panes''', each capable of independently decoding and displaying a RTTY signal. The choice of ''Waterfall'' or ''Spectrum'' is governed by the '''Tuning Display''' panel on the '''Configuration''' window's '''RTTY''' tab; these instructions assume that you've chosen a Waterfall display. The vertical height and horizontal zoom of the Waterfall or Spectrum display is controlled by the '''Tuning Display''' panel on the Main window, as shown in the screen shot above. To decode a signal in the '''Receive Pane''', 1. click on the Mark frequency of the desired signal in the Waterfall display; the yellow traces that indicates the '''Receive Pane's''' Mark and Space frequencies will be positioned over the signal in the Waterfall display, and decoded characters will appear in '''Receive Pane''' 1. if [[TransceiverControl| Commander]] is running, click the '''RTTY receive''' panel's '''Opt''' button, which will direct Commander to QSY your transceiver so that the selected signals Mark and Space frequencies straddle the '''Optimum Offset''' you specified in the '''Modulation and transceiver mode''' panel on the Configuration window's '''RTTY''' tab * if the [[http://www.dxlabsuite.com/winwarbler/Help/SoundcardRTTYReception.htm#2Tone%20demodulation%20and%20decoding|2Tone Demodulator]] is enabled and [[ConfigureRTTY|configured as recommended]] to demodulate information from the same soundcard and channel being used by the MMTTY demodulator, it will decode the selected signal in parallel with the MMTTY demodulator. * if you have a subreceiver or second receiver, you can connect it and your main receiver's audio outputs to your soundcard's left and right channels, and [[http://www.dxlabsuite.com/winwarbler/Help/SoundcardRTTYSettings.htm#MMTTY%20Sound%20Card%20Source|configure the MMTTY demodulator to display information decoded from one channel]] and [[http://www.dxlabsuite.com/winwarbler/Help/SoundcardRTTYSettings.htm#2Tone%20Soundcard%20Channel|configure the 2Tone demodulator to display information decoded from the other channel]]; this enables the simultaneous decoding of two RTTY signals, e.g. a DX station working split and the station with whom the DX is in QSO. * to start a standalone instance of MMTTY that runs in parallel with !WinWarbler, if MMTTY has been installed in the folder {{{C:\Ham\MMTTY}}}, use '''Notepad''' to create an {{{ExternalMMTTY.bat}}} file whose contents are {{{start "MMTTY" C:\Ham\MMTTY\MMTTY.exe -Z}}} and then direct Windows to run {{{ExternalMMTTY.bat}}} * the {{{Z}}} in {{{-Z}}} must be upper case * if the pathname contains one or more space characters, enclose the pathname in double-quotes, e.g. {{{"D:\program files (x86)\MMTTY\MMTTY.exe" -Z}}} With the '''Transmit''' panel's '''Net''' box checked, !WinWarbler will transmit on the '''Receive Pane's''' frequency. To transmit, * click the '''Start''' button in the '''RTTY transmit''' panel * type the characters to be sent in the '''Transmit Pane''' * click the '''Stop''' button in the '''RTTY transmit''' panel Your transceiver should switch from reception to transmission, transmitted characters should appear in the '''Receive Pane''', and your transceiver should switch from transmission to reception after all characters have been sent. You can also transmit by [[Macros|constructing and invoking macros]]. Note: with the '''RTTY Receive''' panel's '''AFC''' box checked, the '''Receive Pane''' will automatically adjust its Mark frequency to track any changes in the received signal. To prevent your transmission frequency from also being adjusted by this AFC action, uncheck the '''RTTY transmit''' panel's '''Net''' box once a QSO has begun. ==== Split Frequency Operation ==== To work a DX station operating "split" (transmitting on one frequency while listening on another frequency), * On the Configuration window's '''General''' tab, check the '''split frequency operation''' box * In the Main window's '''RTTY transmit''' panel, if the '''net''' box is enabled, uncheck it * With your transceiver's VFO A (or Main VFO) selected, click on the Mark frequency of the DX station's signal in the Waterfall display and click the '''Opt''' button as described in steps 1 and 2 of the '''Operating in RTTY''' section above * Select your transceiver's VFO B (or Sub VFO), set your transceiver's frequency to the DX stations' listening frequency, and enable its Split function. If you have Commander running, this can be quickly accomplished by clicking the '''1''', '''2''', '''5''', or '''10''' buttons in its Main window's '''VFO B''' panel to enable split and set VFO B to 1 kHz, 2 kHz, 5 kHz, or 10 kHz above VFO A respectively. === Video === * [[https://stationproject.files.wordpress.com/2014/12/digital-qso.mp4|Working RTTY DX with DXLab]] === Additional Information === * [[DisplayingDecodedInformation|Managing the Display of Decoded Information]] * [[CapturingDecodedInformation|Capturing Information from Decoded Data]] * [[RTTYFiguresLettersUSOS| Figures, Letters, and Unshift On Space (USOS)]] * [[http://www.dxlabsuite.com/winwarbler/Help/Logging.htm|Logging QSOs]] * [[Macros|Using Macros]] * [[RTTYSideband|RTTY: Which Sideband?]] * [[http://www.dxlabsuite.com/winwarbler/Help/SoundcardRTTYSettings.htm#MMTTY%20Engine%20Configuration|Optimizing RTTY decoding with MMTTY Profiles]] * [[http://www.dxlabsuite.com/winwarbler/Profiles/Profiles.xls|Spreadsheet comparing available profiles (including EU1SA) to the '''Standard RTTY''' profile]] * [[AA6YQ-FIR-512| Obtaining the AA6YQ-FIR-512 Profile]] * [[http://www.dxlabsuite.com/winwarbler/Profiles/UserPara.doc|Documentation for the parameters that can be set in a profile]] * [[K3CWRTTYXcv|Displaying RTTY Decoded by an Elecraft K3, K3S, KX3, or K4 - and transmitting too!]] * [[ExternalModemControl|Displaying RTTY Decoded by an External Modem (KAM, PK-232, TinyFSK, etc.) - and transmitting too!]] * [[DecodeGritty|Displaying RTTY Decoded by GRITTY]] ---- [[DXLabDiscussionGroup|Post a question or suggestion on the DXLab Discussion Group]] [[ConfigureRTTY|Configuring WinWarbler for RTTY operation]] [[Operation|Operating in CW, Phone, PSK, and RTTY]] [[GettingStarted|Getting Started with DXLab]]
