Looking for anyone who is familiar with this tiny beacon emitter. I've driven one with a NE555 circuit and hear a very strong
signal But, only clicking. If anyone can tell me how to get it to output an audiable tone of somekind. Thjanks in advance.

It is a data transmitter. You shouldn't expect a tone. The data is decoded by a WRL-10532 receiver.

LOOKS LIKE IT IS DIGITAL AND NOT ANALOG (AUDIBLE). READING A LITTLE SAID YOU COULD HEAR IT ON A UV-5 RADIO, BUT DIDNT SAY "WHAT WAS HEARD" THATS AN FM HANDHELD. MAYBE THIS ISNT WHAT IM LOOKING FOR.

It's been a while but those interested in little UHF data modules, potential for voice transmission and receiving them on handhelds might be interested in my experiments & videos here:

pretty cool, the dra818 (u or v) modules are pretty neat and may be easier in some ways as they are FM.

If the 555 oscillator frequency is low enough (ie audible) you should be able to make it sound like a tone on an FM handheld.
An example of a foxhunt tx I've recently built.

One could use a NE556. Use one half for the audio oscillator and the second half to trigger the modules output on and off. That would make a nice foxhunt beacon.
