SmartSDR™ - Official FlexRadio Systems® SDR Client

By Marcus Roskosch

Open iTunes to buy and download apps.


Official FlexRadio Systems® Client
SmartSDR is a full featured radio client that enables your iPad or iPhone to operate your FlexRadio device.

Please note: This App requires a FlexRadio Systems® Series-6000 Software Defined Radio (SDR) Device.

However, the App also contains a FlexRadio Simulator (Demo Mode) so you can try this App even without owning a FlexRadio. PLEASE NOTE: The Demo Mode audio is by far not as good as when connecting the App to a real FlexRadio. That quality is identical to SMartSDR for Windows.


SmartSDR offers almost all features of SmartSDR for Windows such as:

■ Creation, maintenance of Slices, TNFs, Filters
■ Unlimited number of Slices, Panadapters (limited only by radio model)
■ CWX support including Sidetone and live send mode
■ Maintain all Radio, Slice and Panadapter settings
■ Support for Memories
■ Profiles integration (TX, Microphone and Global)
■ Audio settings supported including equalizers
■ Support for TX Settings like Power including all Tuning features
■ Transverter support

In addition to SmartSDR for Windows, this App offers these features:

■ Band limits and Band maps and modes will be displayed inside the Pan adapter (In-App Purchase)
■ DX Cluster support which displays spots directly inside the Pan adapter (In-App Purchase)
■ Graphical tuning knob for easy and exact frequency selection.
■ Various additional minor bells and whistles such as easy TNF maintenance,
■ direct Bandwidth selection, Split Mode, instant Memory creation and more.
■ Device logging and device parameter monitoring (e.g. PA Temperature etc.)

There are just a few limitations compared to SmartSDR for Windows which are:

- Only one Panadapter visible at the same time.
- Diversity and full Duplex are not yet implemented.


- 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 9.5 (iOS 10.1 recommended)
- A newer iPad (3, Air 2 or newer) or iPhone (5s or better) is recommended

To run this App at your home, nothing else but a regular WiFi connection is needed. You can immediately start using the App.


To run SmartSDR on your home network, nothing else is needed but a regular Wi-Fi connection that can access
your FLEX-6000. You can immediately start using the App.

Remote operation requires a VPN connection (VPN software and hardware not included).

The App supports Multitasking on the newer iPads so you can run SmartSDR in split mode parallel to your browser, Email software or any other App. It is also optimized for the new iPad Pro models.


FLEX-6300, FLEX-6500, FLEX-6700

Awesome app!

WV9L--- ive ran remote for several years. Ran RDP apps, used Commcat, then went to Remoterig RRC, as i found that no app was able to give me full functionality of my rig. Sold my TS-480HX and Remoterig setup last week. Bought a FLEX 6500 and this app. True radio heaven!! Worth every penny spent. My hats off to the developer. All your hard work and attention to detail is greatly appreciated. Look forward to future developments.

Just put in a VPN at home. Now i can work remotely with this app. Love it.
1 suggestion....adding filtering to the cluster would be great. So we could filter by the spotters country.
