Tono_2M-100W_Manual操作说明书手册

INSTRUCTION MANUAL2M·100HSPECIALITIES1.The 2M-100w is in a high efficiency and high output power at the time of transmittingand in with low noise at the time of receiving.2.Complete automatic change-over system is applied in switching from transmit toreceive and vice versa.3.Supplied with Manual T/R Switching,which enables the easy operation of SSB orCW mode.4.When the Power Switch is ON,the TX lamp is lit to indicate that the TX/RX circuitis in operation.5.The 2M-100w is compact A1l Solid State design.SPECIFICATIONFrequency144MHz to 146 MHzModeSSB,FM,CW,RTTYIn/Out impedance50 0hmsOutput transistor2SC2630(E)VoltageDC13.8V (standard)Currentabout 8A to 10ADriving power10w to 15wRF power80w to 90WRF preamplifier gainabout 13dBSizeApproximately 146 x 200 x 58mmNOTES FOR OPERATION1.As the output power of the companion transceiver is to be used to drive this ampli-fier,it is important to ensure that the driving power should NOT exceed 15w.If the driving power is exceeded,the final transistor of the 2M-100w will bebroken down.2.The supply voltage should not exceed 13.8V.If the supply voltage is over 15V plusor minus 153,the final transistor will be destroyed.If you use a stabilised powersupply,ensure that it is capable of supplying 13A with low ripple voltage.If using a regualted power supply it may be found that the presence of VHF radiofrequency energy will prevent normal operation.As a cure,connecting parallelbetween the plus and minus terminals of the Dc output,a capacitor of 250MFD and aRF bypass of either 0.1MFD,0.01MFD,300PF or 100PF.3.It is important that the SWR of the antenna be as low as possible.Under no circums-tances use this amplifier with an antenna whose SWR is not below 1:1.3.Ensure that the antenna is capable of withstanding high power output.4.Resist the temptations to open the bottom plate of the power amplifier and adjustthe trimmers and coils inside.5.Try to avoid transmitting when the ambient temperature is above 40'C.6.When loaded in a car,try to avoid setting the amplifier in a heated place,just as an outlet of heated air or the engine room.7.Be careful not to reverse the polarity when connecting power supplies.-to theamplifier.8.The power supply cord should be directly connected to batteries.When the cordis not long enough,use one which is more than 2.0 square thick.
