![]() The second class of digital modes is a family of modes supported by the WSJT-X program and its offshoots. The digital engine software may also display some kind of tuning aid to help users to tune signals in accurately. This software, in conjunction with a sound card or codec, acts as a modem to translate when transmitting between characters, either stored in message files or input from the keyboard, and the varying frequencies that are actually transmitted, and on receive, between the received signals and the characters displayed on the screen. N1MM+ implements them with the help of either a hardware interface (TNC or TU) or more often, using “digital engine” software. ![]() These modes are conceptually quite similar to CW. There is no restriction on when a transmission may begin, other than the usual admonition to avoid having both parties to a QSO transmitting at once. These messages may be of arbitrary lengths and may contain any information that can be written down in letters and numbers. The first class of digital modes comprises “conversational” keyboard-to-keyboard modes in which the two parties to a QSO exchange messages made up of characters (letters, numbers or punctuation characters). There are two broad classes of digital modes supported by N1MM+.

The reason I am wanting to use RTS is so that ANY Ham software can operate PTT by using the "serial port" RTS line. This particular radio has no line in/out, not any sort of data interface, so I must assert PTT by shorting the SLEEVE and RING on the microphone input jack. Not that I am NOT using a signal link, but am using the cmedia audio USB adaptor and directly coupling the audio in/out to the radio (5-watt X1M) which likes the levels very well. As such I cannot assign RTS nor CTS to one of the GPIO pins. I installed bw_tools and the git programs but I cannot use gpio_? as the system tells me it is not installed. I am successfully using then Raspberry Pi model 2 with both fldigi and qsstv but I still need to get PTT working. I added the singalink explicitly as a device listed in /etc/nf. I tried a million things, but I think I know what fixed it. I wasn't getting any signal in fldigi, no waterfall. I fired up fldigi and could suddenly select port audio devices - and my signalink was in there as the USB Audio CODEC as a playback and capture device. So I installed the portaudio packages and recompiled fldigi with portaudio support (your working package probably has this already). But once I got it loaded, I saw I couldn't select any devices in the soundcard config.Īfter reading the fldigi linux recommendations I figured using the portaudio library on top of ALSA was the way to go. If the package loads for you I'm jealous. I had to add a bunch of packages as you'd expect but finally it compiled and worked. The fldigi package didn't fire up for me, I'm not sure why, so I ended up compiling it from source. Turns out I got it working and never had the capture device show in alsamixer so that was no biggie. I don't see a capture device in alsamixer though, and that's freaking me out. The program 'alsamixer' is showing both cards, and I can select between them. The internal soundcard does not have a capture device, so just card 1 is showing up.
