MCU 4.60 / DSP 2.80, 11-17-2012

* ESSB TRANSMIT CAN USE THE FM FILTER: The wide (FM) crystal filter  
can now be assigned to ESSB transmit as well as FM and AM. This can  
potentially free up a crystal filter slot for customers who were using  
the 6-kHz filter only for AM or ESSB. NOTE: The 6-kHz filter is still  
recommended for high-performance ESSB and AM receive, as it will  
provide significantly better close-in dynamic range than the FM filter.

* TRANSVERTER FREQUENCY ENTRY FIXED:  The previous firmware release  
did not handle direct frequency entry to transverter bands correctly  
(e.g., 144 MHz came out as 180 MHz). This also affected memory recall  
of transverter bands.

4.60 = WOW!  NICE!

Now can you filter out the poor operating styles surrounding the PT0S operations?   ;-).

Frustrating for us little pistols with HOA restrictions.  :-(

Absolutely appalling.  If Wayne could write a filter for THAT sort of
nonsense, we'd all win.

I installed 8 new Lithiums in my KX3 just to try them out….  15 bucks…
Yep that first set worked just fine. I used them for a few weeks off and on listened to am short-wave made cw and ssb contacts more or less for a few weeks.
FB the voltage hovered above 12 volts in the Rx mode… No problem. I am happy.
Today they gave up the ghost.
The KX3 huffed and puffed and shut down :) Time to swap out the old for the new.
Cracked open a brand spanking new set (8 to a pack) and shoehorned them into my KX3 rig. ahhh fresh juice I thought to myself…
Maybe I'll do a few QSO's on 21 since its been kinda good.
Within 5 mins the voltage is at or below 12 volts… WTF!
Is my radio messed up???? no…
Pulled the battery and measure the voltage of each cell… 1.614 +/- on a lark I measure the Old ones… 1.591 +/-….hummmm but in the old 8 pack there was one battery that measured 1.214 +/- volts…. Hummmm
Seems the new batteries are bogus…
I will call the Energizer Hot line in the AM and see whats up.
800 383 7323
So beware of bogus Lithium batteries… checked Amazon battery reviews and saw some folks are having problems with crappy lithiums…. hummmm
I smell a rat.

K3 beta-test firmware revision 4.66 (with DSP rev. 2.81) is now  
available. See release notes below.

K3 MCU 4.66 / DSP 2.81, 3-22-2013

* FSK-D KEYING BANDWIDTH GREATLY REDUCED: This change reduces the  
amplitude of the FSK-D keying sidebands by 25-30 dB at a 500-Hz  
offset, giving the K3 one of the cleanest FSK signals available.

* K3/0 (REMOTE-RIG) IMPROVEMENTS: (1) Supply voltage can go down to  
7.6 V; (2) VFO lock works correctly; (3) TX LED no longer gets out of  
sync.

* IMPROVED HANDLING OF SERIAL I/O (RS232) ERROR CONDITIONS.

* SUPPORT ADDED FOR ALTERNATIVE LCD DRIVER IC. This has no effect on  
radio operation.

* RIT AND XIT NO LONGER TURNED OFF UNINTENTIONALLY: In previous  
releases, changing bands via direct frequency entry (FREQ ENT) or  
remote-control band change commands (FA, FB, and BN) would turn off  
RIT and XIT. This was true even if CONFIG:SPLT SV was set to YES.

K3 firmware rev. 4.81 (with DSP rev 2.82) is now available as a beta release. Highlights of this release:

* RIT can now be turned on/off during transmit: (Note: If RIT is turned on or off during transmission of a CW character, the length of one code element may be affected. This will be corrected in a future release.)

* 10 and 18 MHz are now available as transverter I.F. bands. 10 MHz is particularly useful as an I.F. for VLF and LF transverters, e.g. for the 600-MHz band (~475 kHz). This is because 10 MHz OCO's (oven-controlled oscillators) are relatively inexpensive, and can serve as the local oscillator for a home-built transverter.

* That pesky RTTY 45/75 baud bug has been fixed. The FSK-D/AFSK-A baud rate is now global, meaning that one setting applies in all cases. The band rate is set by holding DATA MD, selecting FSK-D or AFSK-A using VFO B, then selecting the baud rate using VFO A.

* RTTY/FSK transmit improved: In FSK-D mode using an PC-generated FSK input, the K3 no longer exhibits DSP errors (ERR DSE) or loss of communications. Previously, these may have occurred when the K3 was sent too many serial (RS232) commands.

* A number of bugs in Remote Rig mode have been fixed. See release notes (accessible from within K3 Utility) for a full list.

* You can now set the crystal filter lower edge in CW mode to 0.1, 0.2, or 0.3 kHz above zero beat. The default is 0.2 kHz. The 0.1-kHz selection provides enhanced bass response, but may allow you to hear a low-pitched opposite-sideband signal when you're tuned near very strong signals. The 0.3-kHz selection may be preferred by some operators in extremely strong-signal environments. To change the setting: Select CW mode, then go into MENU:RX EQ and tap '0' (CWT) to choose the desired XFIL LO value.
