WARNING TO AVOID DAMAGE THE UNIT!
In order to give enough time to the relays to switch before the RF power signal outputs the transceiver when the PTT is pressed, assure that your transceiver provides a delayed "SEND" control line logic signal. Normally that control line is present on Linear Amplifier connector. Also several transceivers feature a programmable delay, see owners manual of your particular radio.

Alternatively a Transmission/Reception Sequencer can be used.

  LF-HF-VHF-UHF Dual Port By-Pass relays. How it works.  
     

 

 

Default state. (By-passed)

When the Dual Port By-Pass Relay is not activated, pins 3 and 4 of the control line connector are open or the unit is not powered the device plugged on Port B and Port C is by-passed. Both ports (B and C) are grounded.

Port A and Port R are connected.

 

 

 

 

 


Active state. (NO By-passed)

When the Dual Port By-Pass Relay is powered and pins 3 and 4 of the control line connector are joined the internal relays switch-over. The device Input (Port B) is connected to Antenna (Port A) and the Device Output (Port C) is connected to the Radio (Port R).
