Hi Team,

Please help to review the schematic and kindly give us some suggestions.

We need to use NE555 to control TX on/off, is this schematic OK?

Thanks

Daniel,

The biggest issue is that threshold and control pins are shorted together so the threshold comparator has no defined input so the output is undefined (unknown).

What is the the desired function of this circuit?
