Hi All
Can someone give me an idea about how to do a Low frequency , frecuency
counter?, I need to count between 50 Hz and 300 Hz, but not more than that,
and if it's possible avoid interference from higher frecuencies.
I need it to detect CTCSS tones from a given radio channel, so it must have
less than 2 Hz of error, it is possible to do it with a F84??.
Thanks in advance.
