SmartSDR for iOS

Operate your Radio from anywhere

FlexRadio System official SDR Client​

SmartSDR™ for iOS illustrates the versatility of the SmartSDR ecosystem when paired with the FLEX-6000 Signature Series SDR to utilize Apple mobile devices for radio operations. It was designed for those who want to have all the features (and even more) of SmartSDR for Windows on their mobile device either to operate from home or remotely.

SmartSDR for iOS is a full-featured radio client run from your Apple mobile device in the same manner as SmartSDR for Window is used on a Windows PC. You can operate in any mode like SSB or CW (e.g. with CWX with sidetone) by only using SmartSDR for iOS. In addition, you can even run third-party programs on your PC such as N1MM+ or CWSkimmer in parallel with SmartSDR for iOS since it allows you to manage the DAX and DAXIQ settings.

SmartSDR for iOS can run in two modes; Full Control or Remote Control. In Full Control mode, SmartSDR for iOS operates like SmartSDR for Windows, but on an Apple mobile device. Remote Control mode means it can run at the same time as SmartSDR for Windows. In this mode, you will not see the Panadapter with its panafall display because it is already being displayed by SmartSDR for Windows. But all radio, Slice, and Panadapter settings can be maintained remotely by SmartSDR for iOS. In this mode, you can even use the CWX feature of the SmartSDR for iOS to operate in CW remotely.

SmartSDR for iOS also includes optional DX-Cluster and Band plan applets that integrates into the spectrum display. When using DX-Cluster, spots are displayed directly inside the panadapter. Tapping on a spot will directly tune to the right frequency. Several popular DX Cluster servers are already pre-configured but it is also possible to use any Telnet or Skimmer Cluster Server closer to your QTH. The Band Plan tool provides a visual frequency overview in the panadapter of all HF HAM Bands for your particular IARU region as well as the modes and maximum bandwidth.

Requirements (what you need)

  • A FlexRadio Systems® FLEX-6000 series radio
  • An Apple device such as an iPad, iPhone or iPod Touch which needs to run at least iOS 11

Tuning and fine-tuning

Quick and as natural as possible.

You can move the slice with your finger, fine-tune with a graphical tuning-wheel (which regards the Radio Frequency Step setting) or quickly enter the desired frequency manually with just a few taps.


SmartSDR includes a fully integrated DX-Cluster tool. Spots will be displayed directly inside the pan adapter. You can also switch to the DX-Cluster overview where you can set filters. Tapping on a spot will directly tune to the right frequency.

Several popular DX-Cluster servers are already per-configured but it is also possible to use any Telnet or Skimmer Cluster Server. It is even possible to use your own CW-Skimmer, running on your own PC.

Filter maintenance

It is easy to maintain filter settings.

Tapping at the lower end of a Slice or TNF will show the edit screen where you can manually change the filter settings or even Delete the Slice or TNF.
