Question : Radio voice recorder

We have  a radio line and record conversation through the line. We have used Digital Logger's MIL-8000U to record radio lines. But the device gives problems sometimes, it goes off and the application always consumes 100% CPU with AMD processor. I contacted their support and look like they don't care about this small product for bug.
Anyway, today it went down completely.
I'm looking for any alternative to record radio line. Because radio line doesn't have hook, the recorder should record based on the voice level on the line.
Does anyone have any recommendation?

Answer : Radio voice recorder

Can you connect the line to a sound card?

Have you looked into any software solutions such as this?
