Radio collar testing (and live bear webcam)
Had some trouble with the small radio collar today, got a regular “thump” approximately every 1.3 seconds, rather than a beep. Took them to the park and had signal from the center nearly to the western park limits (nearly 500 ft). Then we had a weak signal when I took the collar to the 10th floor of Skirball Center. Almost no signal at ITP (interference?). The frequency of the collar was 148.9000 MHz, if that means anything. Tony says, “I suggest FINE TUNING the frequency when the collar is close to the receiver to get a nice “ping” rather than a “thump”. I don’t figure you’ll get much range with the receiver since the antenna is omnidirectional.”

On the plus side, here’s a website I just stumbled on. A live 24-hour web cam in a black bear’s den. There’s videos of her giving birth 2 weeks ago. She’s hibernating right now. http://www.pixcontroller.com/WebCam/BearDenWebCam.htm
They could only do this because the “bear comes from a long line of research bears” and there was a power supply very near to the shallow den. But it certainly gives ideas. Bears don’t see IR.
