P3

[Richard Thorpe]

For those of us who didn't order a P3  should we download the latest firmware update?

Optional. The changes were entirely in support of the P3.

But it can't hurt to have as many K3 users as possible testing the  
latest code.

Thanks,

The new K3 Utility version is not required, but there are a few months of
changes, and I'd encourage you to remain more-or-less current.

- K3 Utility functions that use EEPROM read and write have been sped up, and
are more reliable. This includes configuration save/restore, crystal filter
configuration, command macro read/write, RF Gain calibration, power-on
banner save/restore, TCXO data entry. Configuration save (at 38400 bps) now
takes less than 5 seconds. Reliability improvement comes from a (private)
protocol that includes a checksum. This improvement depends on MCU support
introduced in K3 MCU firmware version 3.83.  Earlier MCU versions continue
to use the older technique.

- Filter configuration now inhibits enabling a filter wider than 2.8 kHz for
CW. This was required as part of the MCU update for QRQ CW.

- The K3 Utility no longer sends commands to alter the K3's "auto info"
state. N8LP's LP-Bridge wasn't able to support the K3 Utility because it
changed Auto Info. That impediment has been removed. LP-Bridge is an N8LP
product that allows several PC application programs to apparently share a
single COM port that is connected to a K3. You still should not attempt to
load K3 firmware through LP-Bridge or any other K3 sharing software, such as
microHAM's uRouter.

- Fixed a bug in RF Gain calibration that changed the VFO frequency
slightly.

- Revised Tx Gain calibration to preserve the last-used frequency on each
band.

- Added a check during K3 firmware load to look for a P3, and if it's
present, ask the user to switch the P3 off for K3 firmware load. This is a
temporary workaround until P3 firmware supports a "pass thru" for K3
firmware load.

Dick,

Since the Mac version hasn't been updated in a while would you recommend that us Mac users use the Win version instead?

Rick,

Barring any unforeseen problems, I will be releasing the P3 Utility for Mac/Linux soon (within the next week or two). I will be releasing an updated version of the K3 Utility around the same time.

Great,  thanks for your work on the Mac versions.

Dick,

Do you keep a wish list for future releases? I found that the CW memories
editor is too "rough" for me. The half space is not sufficient to make my
call sign to sound perfectly. Could you add quarter space, please.

73, Val LZ1VB
