| Strange carriers on 30 meter band | N4OE | on 10/12/17 |
| 30 Meter Carriers For a long time now I have noticed two signals on the 30Meter band that I cannot identify. The frequencies of these signals are: 10.1215 MHz and 10.130MHz and have no modulation but randomly timed interruptions every few hundred milliseconds. At first I suspected that the interruptions might be 180degree phase changes but that turned out to be incorrect. The phase of the carriers stays constant thru the interruptions. I listened to the two binaurally and verified that the interruptions do not seem to be correlated between the two. I turned off everything else in my lab and listened to the carriers with both an IC706MKII and an ICR75 and I am convinced they are not birdies or radiation from anything in my lab or house. Does anyone else hear these signals! Does anyone have any explanation? Thanks John N4OE/6 jobattle@n4oe.com |
