Pressing Q or E increases the left or right channel (radio) level respectively.

The up and down arrows change the levels of both left channels (for the left radio) and right (for the right radio). The default card reported by alsamixer should be the Pi's built-in card (bcm2835 ALSA). Use the arrow keys to select the control. 3.4.1 Make copies of the Fldigi configuration folder. The Hampi image comes already set up to do run and Flmsg "Left" and Flmsg "Right" corresponding to Fldigi Left and Right. I recommend keeping things as simple as possible: If you want to use Flmsg, make sure only one instance of Fldigi is running. 3.4 Scenario 4: I want to run 2 Fldigi applications at the same time, one for a "Right" radio and one for a "Left" radio.Īttention Flmsg users: It is possible but somewhat complicated to run 2 instances of Flmsg, one associated with the left Fldigi and one with the right. 3.3.1 Follow the directions in Scenarios 1 and 2. Fldigi and Direwolf cannot both use the same radio at the same time. Note that if Direwolf is on the Left radio, then Fldigi must be on the Right radio or vice-versa. 3.3 Scenario 3: I want to run Fldigi on the radio at the same time. 3.2.2 Restart Direwolf using whatever script you use to operate Direwolf. Where y = 12 for the left radio or 23 for the right radio. Open the /usr/local/share/applications/sktop file in an editor (as sudo) and change the Exec= line as follows, then save the file and exit the editor: "Right" radios: BCM 23, also check the corresponding ' = 1 (on)' boxģ.1.2 Locate and edit your sktop file."Left" radios: BCM 12, also check the corresponding ' = 1 (on)' box.Select Rig Control > GPIO and set your GPIO to whatever your radio uses:.Select Settings and select Converter Medium Sinc Interpolator (best for V/UHF - change as desired)įor "Right" connected radios: Check Reverse left/right channels underįor "Left" connected radios, leave these 2 boxes unchecked.Check PulseAudio and leave the Server String field empty.

Open Fldigi, click Configure > Config Dialog.3.1.1 Configure Fldigi (4.1.09 and later) Select your desired scenario from the Scenario sections that follow.ģ.1 Scenario 1: I want to use only Fldigi with one radio. The "Right" radio (uses GPIO 23 for PTT) is plugged in to the rightĦ-pin miniDIN or the TRRS jack if configured.The "Left" radio (uses GPIO 12 for PTT) is plugged in to the leftĦ-pin miniDIN or the RJ45 jack if configured.Likewise, we'll specify the left and right virtual interfaces we create in default.pa below in nf to point direwolf to the correct radio by referencing the virtual ALSA devices we created in the previous step.įinally, we'll create the virtual interface system-audio-playback for use within Fldigi for alerts, notifications, and audio monitoring.Īs sudo, make a backup of /etc/pulse/default.pa:Īt this stage, pulseaudio is ready to use on either the left or the right radio or both at once.ĭecide how you want to use your radios and Fldigi and Direwolf.ĭetermine where your radio(s) is/are connected (applies to the Nexus DR-X and DigiLink boards): We will use environment variables PULSE_SOURCE and PULSE_SINK when starting Fldigi so that it'll use the Fe-Pi audio interface instead of NULL/built-in-audio-card. The changes to this file will set up the Fe-Pi left and right channels and tell pulseaudio to use the NULL audio source (no input audio) and the Pi's built-in sound card for the audio sink (output) by default. This is ONLY needed when using raspbian-kernel 1.20200512-2 or later. These changes break the Fldigi alerts and TX/RX monitor features.įortunately, the fix is simple: Append this text to the end of the line in /boot/cmdline.txt and reboot. The release of Rasbian Buster stable kernel 4.19.118-v7+ (Raspbian package raspberrypi-kernel/testing,now 1.20200512-2 armhf) introduced some changes in how the sound interfaces are handled.

NOTE: If you are using the Hampi image, the majority of the following setup is already done for you. Adjust as necessary if this is not the case. This procedure assumes the operating user is pi and pi's home directory is $HOME and that user pi has sudo privileges (the default).
