Adjusting the squelch level
z When the squelch level is set to “open” the repeater will transmit, so the TX output must be connected to the duplexer
and antenna.
z Use extreme caution when making the squelch adjustment or measurement with a signal generator. Do not connect
the signal generator to the duplexer antenna port. To avoid damage to the test equipment, always connect the signal
generator directly to the RX antenna connector on the DR-1X.
z While the squelch level is being set, repeater transmit operation is temporarily permitted. This will facilitate checking
the performance of the Duplexer, and allow evaluation of the receiver sensitivity degradation (“desense”), during
simultaneous transmit/receive operation.
