Please keep in mind that you might need the EXTFSK addon for MMTTY, if you are using MMTTY via an USB RS232 port.Īs the microHAM device router simulates COM Ports via USB, you might need the EXTFSK addon for MMTTY. Great, now you've got the engine downloaded and installed it's time to fire up Win-Test and get things setup! Note: MMTTY saves buffered, so you might not see the data in realtime but after you close MMTTY (or Win-Test) everything will be there.
If all works properly, shut down MMTTY and go back to Win-Test and start MMTTY from within Win-Test. It should have more than 0 bytes and contain data like this: You might need to save the MMTTY options as a profile. Now close MMTTY and restart it to check whether the options are still set correctly.
Next select File(F) | Log Rx file(L) to activate Logging. To configure logging, start MMTTY (from the desktop, not from Win-Test!), then select File(F) | Options of Received-log to configure the file the information is written to, and enable timestamps. If you want to keep all sent and received RTTY characters in a text file, then you should activate logging in MMTTY - since Win-Test (as of Version 3.18) has no option to log the RTTY received and sent data to disk. Now you are ready to set up Win-Test to launch MMTTY actually you may even want to have it launch two different instances of MMTTY to go SO2R on RTTY! Set up only RTTY decoding and RTTY keying through the sound card and/or COM ports. By the way: although it's possible to control your radio from MMTTY, PLEASE DO NOT configure it as this will interfere with Win-Test trying to take control. We recommend setting up MMTTY as a standalone application first, before integrating it into Win-Test - especially if you wish to get FSK going. Details for setting up EXTFSK can be found at JA7UDE's web site and on AA5AU's extensive Getting Started on RTTY pages.

If you wish to use FSK instead of AFSK, be sure to download and install also the EXTFSK extension, which is to be found on the same page in a ZIP file named comfsk105.zip. Win-Test uses the MMTTY engine by JE3HHT, so the first task, before you can start operating RTTY, is to go to the MMTTY home page, scroll down the page to where the title says "MMTTY Engine", download the ZIP file and unpack the file into a folder where you will be able to find it. You can also select the color that should distinguish the Mark frequency.Downloading MMTTY Engine Note: If you're already using N1MM Logger or WriteLog, you may already have this engine installed so it's worthwhile checking before-hand. Your log can record either the center frequency between the Mark and Space or the Mark frequency. See Pseudo FSK for additional information and a suitable keying circuit.

You can full wave rectify and filter the signal so that it can be used as the FSK keyline signal to a rig that supports FSK transmissions. This signal is a burst tone at the FSK keying rate. PseudoFSK selection generates an additional audio signal on the right channel. The Classis XY-scope will appear noisier than the Pseudo XY-scope. The Pseudo XY-scope is similar with the exception that the horizontal and vertical are phase related to the Mark-Space signals, but not the actual signal. The classic XY-scope is similar to older hardware scopes that show the output of the separate Mark-Space filters, one applied to the horizontal and one to the vertical axis. The Digiscope display can be defaulted to the X-scope or the Signal scope. The resulting bit stream is then processed to extract the byte data. The received signal processing consists of a tuned Raised Cosine Filter followed by an optimized Automatic Threshold Correcting (ATC) detector. You can also disable AFC with the AFC button on the main panel. Select from the Slow, Normal or Fast AFC loop. Depending on operating conditions you may need to adjust the action of the AFC loop. The RTTY decoder maintains an internal AFC system for tracking the desired signal. The extra carriage return will give the physical device time to move to the left margin before new characters arrive. This is very useful if you are communicating with someone using a hardware TTY printer. You can also have it insert a CR-CR-LF sequence instead of the standard CR-LF sequence. You can elect to have fldigi automatically insert a CFLF when it reaches character 72 on a line. You can select from various Shifts, Bauds, Bits, Parity and Stop Bits for both AFSK and FSK keying of the transmitter. The RTTY signal can be transmitted anywhere within the USB passband of the transceiver. Fldigi operates RTTY using AFSK and the transceiver set to USB.
