We are announcing the release of W2 Firmware rev 0.95, and the companion
W2 Interface programs for PC and MAC, rev 1.1.1.20.
The W2 firmware will be the new version your "W2 Utility" program
downloads from our ftp site (automatically, if you have the "Copy new
files from Elecraft into local folder" box checked). Here's what's new
for rev 0.95...
*Rev 0.95, 21-Jan-2010*
* ADDITIONAL CALIBRATION COMMANDS:* *You may now use the "<" and ">"
characters when calibrating your W2 Sensor. The ">" character increases
the calibration value by 5, and the "<" reduces the calibration value by 5.
* ALARM CONDITION RESET VIA SOFTWARE:* *The High SWR Alarm condition
(W2 stops with flashing SWR LED's) may be reset via software. Send the
W2 either a "C" or "c" to clear the alarm. Software can also be used to
detect an Alarm condition by sending the W2 an "I"/"i". If it is in the
Alarm state, the response will only be the character "A!".
* *
* AUTO RANGE MODE IMPROVEMENTS:* *This version includes the most
significant improvements yet to stabilize the Auto Range mode.
* SO2R OPERATION WITH TWO SENSORS: If you are using two sensors
connected to one W2 in an SO2R arrangement, the W2 can now monitor them
both and lock on the one detecting RF. To use this feature send the W2
either a "y" or "Y". The W2 indicates it is in SO2R mode by lighting
only the two "S1/S2" LED's while no RF is detected. While one Sensor is
active, you can change the range and decay speeds as desired. The W2
reverts to normal operation if any button is pressed or it receives
another "Y" or "y" serial command.
* 2KW HF SENSOR SERIAL DATA: The decimal point function for Reflected
Power was incorrect when the measured Forward Power was above 20 watts
(value sent was too high). Now corrected.**
And here's what's new for the W2 Interface program from David, W4SMT...
*Version 1.1.1.20*
* This version requires W2 Firmware Rev 0.95 or higher.
* W2 in the Alarm state now opens a message box window that explains
the alarm and displays the last SWR reading. Clicking the 'Clear'
button resets the alarm on the W2 (sends "C"). Detects the SENSOR
button being pressed on the W2. Also detects alarm state on startup
* Added 'Peak-Hold Textual Readouts' checkbox in SETUP. The user can
now turn off the text display peak holds if desired. It defaults
to on. The state is saved upon exiting the program.
* Made the peak-hold ticks wider for better visibility.
As always, if you have any trouble, please send any questions to
