FLEX-3000™ Accessories

FlexControl™ USB
Controlled Tuning Knob

A FlexControl is the ultimate VFO and radio control accessory for all FlexRadio Systems' software defined radios. Its not just a USB connected tuning knob.  It is much more.

Developed by serious contesters, but applicable for all types of operators, the ergonomically designed FlexControl provides the ability to tune multiple VFOs, RIT and XIT with a simple turn and/or press of the weighted, smooth action tuning knob. 

In addition to the multi-function tuning knob, there are three, multi-state programmable push buttons that you can assign a multitude of radio control actions, such as changing the tune step, RX filters or CW speed just to name a few. 

Unlike other tuning knobs, the FlexControl is not another "mouse" like device and will continue to control PowerSDR and your SDR even if the active Windows program isn't PowerSDR.  This is know as the "focus problem" and the FlexControl solves it; allowing you to have your logging program, or any other program for that matter active while interactively operating the radio with the FlexControl.
