PTT SWITCH / SEQUENCER - this device has been designed to accomodate switching multiple linear amplifiers. Device can be used as PTT switch by selecting the desired output from the front panel selector to 1,2 or 3 or as a sequencer where all 3 PTT outputs fire simultaneously (JUMPERS INSTALLED). While its primary purpose is to switch PTT keying lines this device also acts as optical separation between your radio and linear amplifier due to presence of OPTOCOUPLER (no physical connection - light transmitted signal).
