Hi all, K3 beta firmware rev 4.12 and P3 rev 0.36 are now available. If you have a P3, you'll want to load both. They work together to greatly reduce serial I/O delays with PC applications such as HRD.
There are many other improvements as well. See release notes for both K3 and P3 below. 73, Wayne N6KR * * * K3 Release Notes > MCU 4.12 / DSP 2.60 / FPF 1.13, 9-15-2010 > > * 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 menu. 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: > Originally, CONFIG:XVn ADR was always set to “INT TRN1” to enable > the K144XV. This set all band data outputs on the ACC jack to 0. Now, > XVn ADR has of “INT TRN0” to “INT TRN9” 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 you’re 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). > P3 Release Notes > MCU 00.36/ 9-16-2010 > > * Center frequency and markers now work on UHF transverter bands. > > * Additional latency reduction for K3 commands. > > * Extensive changes to the RS-232 handler. To obtain the full > benefit of the improvements, use K3 firmware 04.12 or later. > > * Added "Knob Tap" and "Knob Hold" to the MENU. > > * Added 8215 kHz to transceiver menu. > > * Fixed missing single line in bitmap display upload. > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
