AB3AP Software Control of Elecraft Gear

Runs on linux, MacOS, and Windows.

I've written some software to control Elecraft gear:

Suggested price: 1 QSL card - I truly would appreciate it!
(Return rate indicates interest, which determines worth of offering software publicly.)

Click to Run! Detailed Info Description
K3 EQ Adjust tx and rx EQ settings for K3.
W1 Control Three meter faces, units of W or dBm.
Antenna Bandwidth Use W1 and a K3 to measure your antenna bandwidth.
K2 Settings Retrieval Save your K2 set up in case of an unexpected reset.
K2 Control A virtual K2 face using artwork from the manual cover. Use pop up menu to choose serial port.
K2 Filter Adjustment Unfinished. Adjust K2 filters programmatically.

  1. Simply click an Elecraft icon above to run a program.

  2. If your web browser doesn't recognize .jnlp files, make it use "javaws" (in your Java distribution's jre/bin directory).

  3. After inially running it, "javaws -viewer" lets you run programs later even when off the Internet.

  4. Send a QSL card to AB3AP. :-)

NOTE to linux users: be sure you are a member of group "lock" and that the directory /var/lock is writable to you or the lock group. The serial port library wants to lock out the serial port to other applications.
