ELECRAFT KX3 OWNER'S MANUAL ERRATARev.C5-3,Sept.22,2017Firmware FeaturesATU data sets for use at different locations:The KX3 stores two full sets of per-band data for the internal ATU(KXAT3).Use the ATU DATA menu entry to select which set to use.Typically SET 1 is used at a home location,and SET 2 for field operation.Note:This has no effect on KXAT100 ATU data,which is stored separately for eachof the KXPA100 amplifier's two antenna jacks.ATU LC network value dis play andLRuse:In either the ATU.DATA or ATU MD menu entry,tapping the ATuswitch shows the present values of L (inductance),C(capacitance)and N(L-network configuration).This applies onlyto the internal ATU(KXAT3).The displayed data format is LxxCxxNy.is a 2-digit hexadecimal value that,when converted to binary,shows which ATU L or C relays are engaged.shows which side of the L-network thecapacitance is on:Nt TX side,and NA antenna side.UsingR:Within the ATU.DATA or ATU MD menuentries,R(hold of the OFS/B knob)now clears KXAT3 ATU data only for the presently selected data set(SET 1or SET 2)on the present band.As before,is recommended when using the internal ATU with a new antenna.Once the data is cleared,very few ATU tune operations will usually be needed to cover an entire band.Note:If aKXPA100 amplifier is connected,the Roperation applies to the KXAT100 ATU's per-band/per-antenna data,notto the data for the internal KXAT3 ATU.PSK63 mode:PSK63 is a faster version of PSK31.Select 31 or 63 baud using VFO A when doing DATA setupUp to 15 W:On 80-20 m,the PWR control can now be set as high as 15 W.Supply voltage must be over 12.8 V orhigher on key-down.If a band other than 80-20 m is selected,power output will be cut back to 12 W max.It must thenbe manually set above 12 W after switching back to 80-20 m.Extended Temperature Compensation:VFO temperature compensation improves stability for data modes and2 m/4 m operation.See:http://www.elecraft.com/manual/KX3%20Custom%20VFO%20TC%20rev%20A9.pdf+5 VDC on 2 m/4 m antenna jack:Many high-band transverters and other gear can use a DC voltage of 3-12 V onthe center conductor of the antenna coax to provide T/R switching of other functions.The KX3-2M/-4M module canplace+5 VDC (+/-0.3 V)on its SMA antenna jack if desired.To turn this feature on/off,locate the 2M/4M menuentry and tap 2'(ATTN).The parameter will be either TXant 5V-(off)or TXant 5V+(on).("ant"is actuallydisplayed as a small antenna symbol.)CW QSK mode selections:Taping'3'(APF)in the CW WGHT menu entry selects either OLD QSK (original)orNEW QSK.The latter reduces artifacts heard in the receiver during CW keying on a noisy band,at the expense of aslightly longer receive recovery time.Fast Message Play:A long-hold ofMSG(~3 seconds)puts the KX3 into FAST PLAY mode.In this mode,theBAND+,BAND-and FREQ_ENTswitches can be used to playrepeat messages 1,2 and 3 immediately,without theneed to first tap MSG To turn of fast play,hold MSG for ~3 seconds again,or turn the KX3 off and back on.CAUTION
