QSXer (Freeware)

CommCat QSXer is a free program that lets you operate your station from afar using your Apple iPhone or iPad. QSXer also sends your current operating frequency, mode, and a short note to the MyQSX web site where it is displayed on the MyQSX Activity Map. This and additional info is also shown on your own QSXer web site.

QSXer has its own rig control program and optional VoIP for 2-way audio. QSXer also works with Ham Radio Deluxe, TRX-Manager, Logic, and HAM-LOG.

Temporarily turn off your antivirus program and download the file by clicking the button below. Install by double-clicking the package icon. Start QSXer and follow the instructions to request your free QSXer account. Within minutes you'll be live on the MyQSX Activity Map. (Version 3.1.0 was released June 24, 2016.)


Using Vista, Windows 7, 8, or 10?

Vista/Windows 7/8/10 users can install and run CommCat 4 without using "Run as administrator" or modifying your User Access Control (UAC) settings. (Windows 10 is the latest Microsoft operating system, the successor to Windows 8.)
