Say what you will about Coast to Coast AM; I consider it an asset in the game of mediumwave DXing*. During the past week, I used my Tecsun BCL-2000 and my Eton E5 on a few occasions to receive WWL on 870 khz. But a peculiar thing happens before I can hear a positive identification from the broadcast. As a half-hour mark approaches, the signal weakens considerably, and I am lost in a world of static.
Now, I appreciate the fact that this signal travels a great distance, and continuous reception would be a fluke. But it seems odd that the signal regularly fails at these intervals. Is there any way that this is intentional?
*(I'm not working on a new mediumwave DX initiative at this time.)
