We are announcing the release of W2 Firmware rev 1.00.

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...

Rev 1.00, 12-April-2010

* SWR ACCURACY: As a result of our continuing product improvement, a 
different algorithm is now used to calculate the SWR value. Besides 
offering greater accuracy at lower power levels, the SWR data available 
from the Serial Port now reports the range of 1.00:1 to 99.99:1, giving 
much finer resolution of SWR readings.

* SWR ALARM CHANGES: The trip points for the SWR Alarm now match the SWR 
LED’s on the front panel of the W2. The range is still 1.1:1 to 5.0:1. 
Sending the W2 a “[” lowers the trip point, and “]” raises the trip 
point. Note the decimal point is implied in the serial response, i.e. 
“[25;” means the trip point was lowered to an SWR of 2.5:1 and “]40” 
means the trip point was raised to 4.0:1.

* SWR ALARM RESPONSE TIME: You can use the “PTT RY” RCA connectors on 
the back of the W2 to help protect your amp in case of high SWR. The 
response time that it takes for the relay to trip has been improved and 
can now catch an “I” sent at 60 WPM.

* SERIAL COMMAND CHANGES: The Serial Command set has had some minor 
changes in output format. Please see the “Elecraft W2 Serial Interface 
Commands” document available here on Elecraft.com.

As always, if you have any trouble, please send any questions to 
k3support at elecraft.com.
