* When the SEND terminal controls the inductive load (such as a relay), a counter-electromotive force can cause
the transceiver's malfunction or damage. To prevent this, we recommend adding a switching diode, such as an
"1SS133," on the load side of the circuit to the counter-electromotive force absorption.
When the diode is added, a switching delay of the relay may occur. Be sure to check its switching action before
operation.

* VSEND is used for the 144 MHz, 430 MHz, and 1200 MHz bands, and HSEND is used for the HF/50 MHz bands
