SDR-Control Mobile

SDR-Control Mobile is an exceptional app and easily one of the best tools available for radio enthusiasts using the Icom IC-705 and other compatible radios. It works flawlessly on my iPhone — smooth, stable, and incredibly responsive. The connection to the IC-705 is seamless, and operating remotely has never been easier or more enjoyable. The user interface is thoughtfully designed, striking a perfect balance between functionality and ease of use. The real-time waterfall display is fast and sharp, tuning is precise, and the app provides full control over the radio. One of the standout features is the newly added SSTV decode support — it works beautifully and adds even more versatility to the app. The integrated logging, CAT control, and overall attention to detail make it feel like a full-featured SDR station in the palm of your hand. What’s equally impressive is the regular stream of updates and improvements. The developer is clearly committed to refining and enhancing the app over time, which makes it even more of a worthwhile investment. If you own an IC-705 or any of the compatible radios and want true portable SDR control, this is absolutely the app to get.

What a joy to use software that has been so carefully and meticulously crafted to make SDR easy! Cheap? No. Worth your money? All day long.

I am using this with a cellular modem at the radio end and a little iPhone SE. The “trick” to using an all cellular setup is to run Tailscale, which is a free VPN system. T/S gives you a fixed IP address and can create a subnet with the addition of a humble Raspberry Pi. With the above you enter the IP address shown on your radio regardless of CGNAT, cellular IP address changes, etc. There is a free Tailscale app for the iPhone. The Tailscale web pages cover all the above in great detail. One tip, use the free “ping” app to make sure you can reach your radio before buying this app. The app itself is amazing, you even see the memories stored in your radio as markers on the spectrum display on the iPhone.

This is one bloomin’ good app. Have used the Mac version for a couple of years now and was overjoyed when Marcus produced versions for IOS. They are rock steady and work seamlessly. Have been sitting in the sun today, 178 miles away from my IC-705, working the world via a 4G connection. Can’t fault the IOS version in any way. Absolutely brilliant and worth the slightly high purchase price. But if that helps further development it’s a worthwhile investment! How about incorporating a tool for WSPR Marcus? Nick 2E0FGQ

Previous version had the occasional flaky moment for me, either missing ft8 cycles altogether, or locking into transmit… aside that from that, it was pretty much perfect. Then here comes the update with a very noticeable improvement in stability - I really can’t fault the app now… perhaps the only thing I would ask for… have the transmit checked and locked by default maybe?

To get it to connect to the internet away from home location ! Once set up, it’s, simply brilliant, all modes including FT8 anywhere, any time, including across mobile data networks. iCloud logbook, also my IPhone version works well on my IPad too Works with Bluetooth IPods for total hands free operating! Well done Marcus, 73 de Dave

I have only recently started using the app which I'm doing on both the iPhone and iPad but before this used the app for Flex radios. Very impressive, the ability to control the radio from an iOS device is great but add on CW decoding and sending that works, FT4 & FT8 and you have a very light and portable system. I’m hoping that Marcus will add more modes and features in the future and the app goes from strength to strength. As I write this I'm sitting in the middle of a field in a camper van happily working FT8 on 40M with the IC705 and a mobile whip.

It’s a great app on Wi-Fi around the home,also on a good Wi-Fi access point when operating remote ,but app struggles on audio rx packets on remote when using mobile carriers I have tried vodaphone and smarty sims and they keep breaking up the audio rx packets also bought a 4g router and the same results,my Icom rsba1 v2 software works flawlessly on these networks,I think more work is needed to address this problem remotely

I’m with EE & I am struggling too get the App to work over mobile data when out portable. I’m still having to use my partners EE hotspot, Work that out? Every other App I have works fine for remote access… however it still is a great App 👍 worth the money …

Works good for SSB ops or SWL listening. FT8 is usless. Decode signals are 12db lower than WSJTX. So miss a lot of usable signals and miss lots of DX. Its a coding issue, as i can have WSJTX running in parrallel with the same radio at the same time and see the signal level issues, and less decodes on the app. Dev has confirmed but has no intentions of addressing issue. I have the extensive email chain of all my tests and his confirmation. Somehow he keeps getting my review removed. This is like the 3rd time its been removed now. Makes one wonder what good reviews are. I have the phone, ipad, and mac versions. Same issue on all platforms.
