I just put together a new W2. I'm finding that the Remote PTT Control isn't working. I have the line for the ptt to the amp from the rig broken and plugged into the two ptt ry rca jacks. Text says it should break that line or the ptt when you encounter high swr but it don't. In the configuration utility I have alarm turned on. What am I overlooking? 73 Dwight NS9I
