From eacd76cb80db12adcce74980e69d116911a8cde7 Mon Sep 17 00:00:00 2001 From: Szymon Dziok Date: Tue, 17 Jun 2014 23:13:15 +0000 Subject: Radio and radio recording for Samsung YH-920. There is no simple method to detect radio through the 3-wire interface, so it's not implemented for the YH-925 for now. YH-920 always has a radio.
