Just a thought to consider, have you tried running the USB devices with a

I ran into an interesting problem with a couple of USB-to-RS232 adapters I had. Same cheap no-name brand, same chipset, both serial number zero. Individually they worked fine. When I plugged the second device into my system (Fedora Core, don't remember which drop) while the first one was still connected, the system hung as soon as I tried to access the serial ports. The only way I could avoid it was to not use both identical devices on the same system (the GPS is now connected through a different brand USB-to-RS232 adapter with a different chipset). Since you're using cheap USB sound chips in these adapters (and probably the same brand and model), do they have identical serial numbers to thereby confuse the USB drivers? It seems to cost extra money to get USB adapter chips with unique serial numbers, so that's something that is commonly skipped in the low-budget parts.

Re: AX.25 Packet Survey
I run an APRS digipeater/igate on a Pi4B (Buster) using Direwolf 1.7. The sound card is a Syba sound fob modified per the instructions on the AllStar web site. The radio is a retired General Electric commercial radio. It operates at our club repeater site. Patrick (N3TSZ)

Re: direwolf, SignaLink, Raspberry Pi
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

Hello Lynn,
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. 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 |
