New to forum here. Looking for a replacement for the ultra basic 4N25 interface that I built 11 years ago. Is the Digirig compatible with the seemingly simple 2AT l???

Thanks…

Looking at the manual, the connectors use the same [pinout as ICOM ID-52](https://forum.digirig.net/t/id-52-interface/344). If the spacing is the same then it can be used with the combined jack, otherwise you can use separate 2.5/3.5mm jacks.

Outstanding!! This is awesome news. The 2AT is excellent as a satellite radio due to how good the RX is. I still use mine for FM sat downlinks, as well as ISS APRS on 145.825.

Thanks for the reply!!
