This page contains some information on different hardware for interfacing audio, squelch and PTT to transceivers.

S56AL interface v2 RPi

New interface from Aleks s56al (ex s54s) especially made for the RPi. USB audio and squelch/PTT via GPIO.

S54S interface

There is an older interface designed by Aleks, s56al. I used this interface for many years but after switching to new computer hardware, a Cubieboard, I discovered that it dampened the outgoing low frequencies too much, so transmitted CTCSS did not work properly. It worked OK on my old computer so maybe it’s the combination of the Cubieboard and the S54S interface that does not work.

WB0RXX interface

WB0RXX/Tim has constructed an interface circuit that he use with his SvxLink system. The schematic can be found here.

Standard EchoLink interfaces

Typical EchoLink hardware may work with SvxLink as well. Have a look at the EchoLink interfaces page. However, I have not tried any of these so there are no guarantees. Please tell me if you get any of the interfaces working or if they are not working.

DMK Engineering URIx

These interfaces have been reported to be in use by some users but you need a version of SvxLink after 01 may 2019 since there were a bug in previous releases. You may also need to add a udev rule like

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0d8c", ATTRS{idProduct}=="013a", MODE="0664", GROUP="plugdev"

to a new file /etc/udev/rules.d/50-usb-uri.rules to give SvxLink access to the device. Make sure that the user running SvxLink is a member of the plugdev group.
