There are a few other clandestine Hifer beacons that are hidden in the
Southwest desert and running on solar power. Check 2097.45 kHz. An
"A" is sent every 9 seconds. Also check 4079.65 kHz. The CW beacon
sends "TMP" and then the temperature in Morse. Supposedly located in
the western AZ desert. There is also a cluster of "beepers" and
"ditters" between 4095 and 4096 kHz located somewhere in the California
Mojave Desert. All these beacons are around 100 mW and solar powered.
