DIGITOR D-2510 INSTRUCTIONSThank you for your purchase of the Digitor model D-2310 2m RF power amplifer.Please follow theseinstructions for reliable operation from your amplifier.Initial ConnectionsThe D-2510 RF ampiifier is designed for use with low power FM or CW transmitters operating in the 144-148MHz range.Typical uses would include boosting t!e operating range of a handheld transceiver whenbeing used in a vehicle or base station application.An inbuilt low-noise GaAs FET receive pre-amp aidsin reception of weak signals.The amplifier operates from negative ground 13.8v DC.and is supplied withmounting hardware that can be used for both vehicle and base station areas.Before mounting the ampliferin a vehicle or other confined area.ensure that sufficicnt air can flow around the D-2510 heatsink to aidcooling.a)Check that the amplifier front panel switches are both in the "Off"position.and that a 5amp fuse ismounted in the fuse holder in the red DC lead.b)After determining a suitable mounting position.connect up the amplifier DC lead to your 13.8v DCpower source.The red coloured amplifier lead is the positive connection.and the black coloured lead is thenegative connection.Take care not to reverse the polarity of the amplifier's DC supply,as damage to theamplifier may occur,or the fuse may blow.If mounted in a vehicle,also ensure that the DC voltage of theelectrical system does not exceed 15v while the engine is running.b)Connect a coax patch cable between your transceiver and the SO-239 socket marked "Tx/Input"on theamplifier rear panel.As most handheld transceivers use a BNC antenna connector,it may be necessary toconstruct a BNC male to PL-259 lead using a short length of high quality RG-58C/U 50 ohm coax cablec)Connect the coax lead from your external antenna to the amplifier rear panel SO-239 socket marked"Ant/Output".Check that the coax leads now connected to both sockets on the rear panel of the amplifierare tightened firmlv.DO NOT OVER-TIGHTEN.OperationOnce you have completed the initail connection stage,the D-2510 amplifier is ready to operate.with achoice of using just the transmit or receive amplifiers,or both.a)To activate the transmit amplifier.simply locate the switch marked "On/Off Power"on the right-handside of the front panel.and switch it to the On position.The red LED marked "Tx"will light up.Now.whenever the amplifier detects a transmission on its input connector it will activate the amplifier's Tx/Rxswitching circuit,and the amplifier will provide boosted RF output.Note that the transmitter connected tothe amplifier input must provide a nominal minimum of 200mW RF for the amplifier's "Carrier Detect"circuitry to operate reliably.The D-2510 amplifier is capable of transmissions at full power for up to10mins,but must be allowed to cool down sufficiently between such extended transmission sessions.b)To activate the GaAs FET receive pre-amp.locate the front panel switch marked "On/Off Rx"andswitch it to the On position.The green LE
