If you get it too high, Vara FM will tell you to turn it down. If you are failing and know you have a good signal path to the destination station, try increasing the Signalink TX control and repeat the test. So, the initial drive level must be high enough for the destination station to decode. When you click the "plug" button: A data block is sent to the destination station indicating an Autotune is in progress, using the current drive settings The drive level is then set low and a test block is sent The drive level is increased and another test block is sent This process repeats 8 more times The destination station then replies with the level that had the best S/N reading at the destination station If the first block is sent with a level that is too low, the destination station doesn't know a Autotune is in progress and ignores the rest of the blocks. This keeps it simple and repeatable.On Sat, at 3:49 PM Scott Currie wrote: OK, so the way Autotune works is as follows. At the moment, I have a couple of bare wires that I short to start PTT, which I want to connect to a (or 6 as appropriate) that I would like to trigger with RTS.Īnyone have some idea how to set this up? 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. USB Codec audio source, if Signalink is connected, and you want FLDIGI to work. I added the singalink explicitly as a device listed in /etc/nf. 1) Windows 10 Update 1803 changed the PCs Microphone privacy settings. I tried a million things, but I think I know what fixed it. I wasn't getting any signal in fldigi, no waterfall. When we setup HRD we will do the opposite. Fldigi Setup Easy RTTY (AFSK) PSK31 & CW. In Configuration, go to Fldigi under Applications and uncheck the box to start Fldigi on startup. These are the virtual audio cables we created with VAC program. NOTE: There is no need to start the Fldigi service in Log4OM. Assign the Input to Virtual Cable 1 and the output to Virtual Cable 2. 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. In PowerSDR setup the VAC (Virtual Audio Cables). 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. Zello is a popular walkie talkie / push-to-talk. use software such as Ham Radio Deluxe, FLDigi, WSJT-X to operate PSK31, FT-8, JT9. HamScope - HamScope is a freeware windows multi-mode communications. How to Setup FLDIGI FlDIGI software has five components used for this presentation: FLDIGI. If the package loads for you I'm jealous. FLDIGI AND SIGNALINK SETUP WINDOWS 10 HOW TO. 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. In the new window that opens, click the + symbol next to the Soundcard section to expand it. Turns out I got it working and never had the capture device show in alsamixer so that was no biggie. FLdigi Click the Configure menu and select Config Dialog. 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.
