direwolf, SignaLink, Raspberry Pi
|
Lynn Deffenbaugh
¿ªÔÆÌåÓýGreetings, I'm trying to get direwolf on a Raspberry Pi to use a SignaLink USB as the audio interface to an IC-706MKIIG.? I've used this SignaLink/radio combination from Windows for many years, but would like to try it now from a Pi.? Here's what I'm seeing so far (removing the devices that aren't the SignaLink): lsusb aplay -l alsamixer -c 1 direwolf receives with this setup with no issues.? But when it tries to transmit, I see the red/pink/magenta [0H] line with the packet, but the SignaLink PTT light doesn't go red and the radio doesn't key up.? The Rx volume control on the SignaLink does affect the audio level of the receive packets.? But I find it strange that alsamixer only shows one control. I have a DINAH audio interface on a different Pi and alsamixer shows two controls, one for Speaker and one for Mic, and a 3rd for Auto Gain Control.? The Pi with the DINAH and direwolf has no trouble keying the transmitter, both the IC-706MKIIG or an Alinco DR-135 both using the same 6 pin mini-din connector. Any/all things to check would be welcome, especially if someone is actually using a SignaLink USB with direwolf on a Raspberry Pi! Lynn (D) - KJ4ERJ - Author of APRSISCE

¿ªÔÆÌåÓýHello Lynn, alsamixer -c 1 Signalink units have limited controls via alsamixer as some of their controls are ONLY available via hardware POTS on the front of the unit.? There is the F3 view to set playback levels and F4 view for microphone levels.?? The key setting here is that you must increase your playback levels higher and higher until the TX LED on the Signalink lights up.? Unless you can get that LED to light up, you aren't keying the radio. Another test you can do is connect a set of headphones to the back of the Signalink and see if you can hear the transmitted audio you expect to be coming from Direwolf.? If you don't hear anything, you have some form of a configuration error.
These use different sound chips and have different controls.? If I was to recommend it, I would recommend to use the DINAH over the Signalink. --David KI6ZHD |

On many systems (like the Pi), the playback and Capture devices may be listed separate, even they they are on the same device. Press <F6> to get a list, and it should show a list of devices. See if there is a separate Capture devie for the USB codec. You can also try <F4> to only show Capture devices. With the Pi (Bullseye) and regular USB sound card we recent configured for balloon tracking, the startup of AlsaMixer only showed (as yours does) View: Playback.? We used <f6> to find the 'Capture' device and configure it. Hope yours is similar. Robert Giuliano KB8RCO
