Hi all,
We've just posted updated firmware on our FTP site. Be sure to install
the latest version of our firmware downloader (K3 Utility), revision
date 12-9-07, before you do the upgrade.
Here are the changes in this revision (within K3 Utility, use
"Help"/"K3 Firmware Release Notes"):
MCU 1.53 and DSP 1.47, 12-19-07
* TX INH menu entry added (Transmit Inhibit). This can be used in
multi-transmitter stations
to control access to station resources such as amplifiers or
antennas. Default is OFF
(no inhibit function; pin 7 is then an output used as XVTRON). If
set to LO=INH or HI=INH,
operator must supply an external TTL or open-collector/open-drain
driver (a pullup to 5V
is required in this case).When the rig is inhibited, the TX LCD
icon flashes slowly (same
as TX TEST mode). Using transmit-start switches (XMIT, TUNE, ATU,
M1-M4) results in
a brief "TX INH" message on VFO B. The key, keyer paddle, /PTT, and
TX via PC
commands are all nonfunctional.
* S-meter linearization above S9 has been improved. (Much greater
accuracy is
possible via an automated calibration algorithm. This is still in
development.)
* LINE IN function now behaves correctly on power-up.
* Receive filter controls (SHIFT, WIDTH, etc.) and switches (XFIL,
etc.) are locked out during
transmit.
* TRANSVERTER SUPPORT:
1. The XVn OFS menu entry is functional (+/- 9.99 kHz offset,
per transverter band).
2. Elecraft XV-series transverter address is being sent via the
auxBus.
3. M->V and V->M now work with transverter bands.
4. Direct Freq Entry works between HF and transverter bands.
Examples of direct
freq entry on transverter bands: 144, 144.2, 144.23, 144.235.
73,
