The 26600 beacon that I know of is located in the Southwest US. It's actual frequency varies between 26600.1 and 25999.9 depending on the state of the battery. It seems to get quite weak when the frequency drops below 26600. It just transmits very long dashes at the moment, no ID.
The current duty cycle seems to be rather hard on the battery. In the future, the duty cycle may be lowered or the panel and battery upgraded.
It seems from what I have been hearing that there may be one or more other beacons nearby.
Here is a Argo capture that I took earlier. Notice the duration the ticks. loooong dashes
