Elecraft K3S firmware v4.12

MCU 4.12 / DSP 2.60 / FPF 1.13

• K3-to-P3 SERIAL COMMUNICATIONS: The K3/P3 RS232 interface has been optimized to eliminate problems with VFO tuning and some third-party PC applications such as HRD.
• DVR TRANSMIT MONITOR SEPARATELY ADJUSTABLE: Applies to TX message play as well as transmit playback of the 90-second loop.

First, set CONFIG: TX DVR to IND (independent) and exit the men​u. Next, hold in the CMP/PWR knob to select MON. Holding the knob in a second time alternates between MON xx and DVR xx. You can adjust MON or DVR level during transmit playback.

• NO GAP IN 6-METER POWER RANGE: The PA now kicks in at 9 W on 6 m, rather than 13 W as on the other bands. This eliminates the original gap from 9 to 12 W on 6 meters.
• 60-METER CHANNEL HOPPING DOWN TO 5.366.5 KHZ WORKS:

Previously, the PLL voltage would sometimes go to zero in this case.

• VFO B to A COPY NOW UPDATES THE P3. This is useful for re-centering the P3 at a desired center frequency. For example, you could leave VFO B set to the center of a band segment. After tuning VFO A around, use VFO B>A to go back to the center. (To use VFO B>A, assign CONFIG: VFO B>A to a PFx or Mx switch.)
• K144XV S-METER CORRECTION: The S-meter is now properly compensating for the added gain of the K144XV.
• K144XV BAND-DATA OUTPUT ADDRESS RANGE INCREASED:

Or​iginally, CONFIG: XVn ADR was always set to ÒINT TRN1Ó to enable the K144XV.

This set all band data outputs on the ACC jack to 0.

Now, XVn ADR has of ÒINT TRN0Ó to ÒINT TRN9Ó for the K144XV.

Band-data outputs are set accordingly.

This may be useful when the K144XV is used as an IF for higher-band external transverters. (If you have a K144XV, the original INT TRN1 will now be INT TRN0 in the menu.

This is the new recommended setting if youre not using external transverters in conjunction with the K144XV.) NOTE: When using the K144XV, XVn RF can be set to the RF band of an external transverter that is using the K144XV as an I.F., rather than at the 2-meter band edge (144).
