UPDATE: Accelerators are no longer supported on Internet Explorer. I'll keep this post around for historical purposes.
I created an accelerator for IE 8 and later that enables you to lookup amateur radio call signs on QRZ.com.
To install the accelerator, click on the following link, turn on the Make this my default provider for this Accelerator Category option, and then click the Add button:
To use the accelerator, just highlight a call sign you see on a web page, click on the accelerator icon and choose Lookup Call Sign on QRZ.com.
Try it with my call sign: KF7GUG.
