It would seem to be a 152.815 TRANSMIT xtal...the fundamental freq of
course would be something different. The third wire could be a ground
for the case of the xtal.

A mi me parece un cristal de 152.815 Mcs de salida para un transmisor.
La frecuencia basica será algo diferente, depende en el modelo del
equipo, su frec. IF, etc. El alambre tercero sería una conecxion
aterrizada del casco del cristal. 8-76 mas probable significa la fecha
de fabricacion.

Thanks for your help
