Nice idea but needs moodification in my case Time Owned: 6 to 12 months.
This mixer interface did not work in my case as supplied. It assumes "single ended" wiring from loudspeaker and takes ground from the power supply, i.e. no transformers here. Audio transformers are only used in connection to the PC. Microphone inputs to the radio have no transformers as well. My station uses two different power supplies for two radios. So it resulted in excessive hum and I had to add additional transformers. SO2R operation needs also modification to supply both radios with audio. No circuit diagram is provided but a mix of circuit- and block diagram. For this price I would have assumed:
- Full support of SO2R
- Real circuit diagrams
- Galvanic decoupling (= transformers) of all audio interfaces

It is good as a basis for your own modifications but then a full circuit diagram would be helpful.

It may be good if you only use one radio at a time.
