Best Option for Working Remote
I have used this app since picking up my AU-510m from Dayton in 2026. The app makes it so easy to work the rig from another room or even another state! Macros are flexible and the CW Decoder is one of the best available!
No funciona con smartlink
No funciona con smartlink, da muchos errores y es imposible hacerlo funcionar. Decepcionado
Audio is clipped or boxy
Hello, I really like this software for iPad for the Flex Radios. Two things. I purchased this for my iPhone, but it doesn’t work on my iPhone, says I need to purchase it, but it works on my iPad. Go figure. Second, on my iPad, I got my Bose NC headset adjusted to work perfectly with my iPad and this software.. Then this morning I got on the air with my iPad and I was getting very bad audio reports. They say it sounded boxy and they couldn’t understand what I was saying. I thought maybe it’s the Bose Headset, but when I did this on my Android, the audio reports were perfect. Maybe it was the latest software with the Bluetooth? Here is extra info. This is an iPad Air 2 with version 15.8.1 I tried using only the microphone with the iPad only ( not the Bluetooth Bose) and I got the same distortion, so it’s not the headset. I would like feedback, advise to fix this issue. Thx 73 HC5DX
Having trouble getting a software to work on the ICC 7300.
I would like to cancel my subscription for this ICC 7300 It is made by flex radio I’m waiting on a delivery next month then I will get your software 73’s Chris Nm5f
Buona app ma …….
App interessante, non sempre funziona come dovrebbe forse per colpa della connessione Comperata visto che ho un ipad 12,9 Quando riesco a farla funzionare va abbastanza bene lo stesso vale per iphone
Fantastic software
I have a large flex system two radios 860 6600 with tuner genius, antenna, genius and power genius I was really struggling running this on windows with flex software kept having slice master other third-party apps and windows. Every other day updating the software kept crashing system. I was spending hours of my day trying to keep windows working. I packed it all in scrapped windows went and bought a new Mac and I used Marcus‘s SDR software to do everything it is fantastic now I play radio with built-in FT8 whisper and logging programs also DXlogger is a fantastic logging program as well and an optional JS8 CALL software everything works radio always hooks up my Flex radio‘s be work better than ever. I was ready to sell all my radios and throw rocks at them . Marcus software save me the radios work fantastic now I have no problems. Flex radio’s are fantastic. Just don’t use Windows and flex software. This is your ticket. Buy his suite of software and it works fabulous. I also have his Icom control software it works beautiful with a 705 and a 9700 works fantastic. This is a software for you if you want it simple and just to work. Can’t go wrong with this software and running flex on an apple is the way to go.
CB Band
Da ich aus welchen Gründen auch immer den Entwickler nicht so erreichen kann muss ich es eben so versuchen. Ich bin CB Funker aber das 11 Meter Band geht hier wohl nicht!? Warum ist das so? CB ist nun mal der Einstieg ins die Welt des Funkens! Wenn das noch gehen würde wäre ich auch bereit für die App zu bezahlen! Bitte um Kontakt.
Scaricata su iphone e iPad
Chiaramente in possesso di un Flex 6600 e interessato a delle prove di remotizzazione ho scaricato la app. Funziona molto bene e devo dire che lo sviluppatore aggiorna e migliora costantemente il prodotto. L’utilizzo su IPad e’ decisamente più pratico che su iphone. La inevitabile latenza che a volte si riscontra e’ determinata dalle reti non sempre all’altezza delle nostre aspettative.

Doesn’t work with headphones
My entire English class now knows I’m a nerd (if it wasn’t already apparent). Put my headphones in and started to listen in only to realize everyone else could hear the ATC tower I was tuned into. Please allow for headphone compatibility.
Awesome App
I find myself listening through the app more than on my Flex Radio.
App says it’s free, but then you have to pay to use it.
The app can be downloaded for free, but then requires a $60 in-app purchase to use even its core functionality. The price isn’t the issue, it’s reasonable for what the app does, the approach just comes off as scammy as I’ve now downloaded an app that essentially does nothing without at least one additional purchase. Just list the price in the store. I’m frankly surprised Apple allowed this.
It used to work great
It worked great until the last update. How do we contact you to resolve issues? When selecting “Contact Developer” it brings you to Flex’s web page, not yours.
Na ja
Ich hab mir die App runtergeladen und musste feststellen das einzige was läuft ist die Demoversion! Man muss sich hier und da anmelden, es ist kompliziert und dann stellt man fest ich muss noch dies und jenes kaufen. Es nervt einfach wenn man umsonst etwas läd und zum kaufen „gezwungen“ wir. Ich habe die App wider deinstaliert !
Can’t add a Slice.
73! Why I can’t to address a TX Slice? iPhone 6 with iOS 12.4.6
Truly radio anywhere!
To be able to open the app and access all the best of the Flex system anywhere is a blast! The app keeps getting better. To have a few minutes, open the app, and bag some DX or POTA is just too cool!
Not ready
Crashes every time I use it for more than 3 minutes. Lost 3 DX calls in progress. Crashed. No info. No reason. Simple setup. Just up and crashed. $60 wasted. Flex 6400M latest iPhone. Software engineer by trade. Seriously. This app is amateur and not in the good way. Flex Systems should be ashamed this is offensively bad. What a sham.
Mostly good
It’s very nice to be able to control my flexradio from my ipad. Sitting on the deck or away from home. The iPad SmartSDR gives nearly complete functioning of the flex. Held back on the final star as the user interface does not have any keyboard control. I cannot type in frequencies or use the arrow keys to tune across the bands. While the iPad is primarily a tap-device, the keyboard is a very common accessory and should be supported within the SmartSDR app.
Costosa
Costa troppo. Si perde lo spirito del radiantismo con un costo così elevato per utilizzarlo. Bastava abbassare la somma e dare la possibilità a tutti i radioamatori di utilizzarlo tranquillamente
demo
Demo volume is too high
Hamshack In The Garden.
Best way to operate a FlexRadio is using this app sitting in the garden. The implementation is superb and includes many features not in the windows version. Naturally some things are easier in the shack with dual 4k monitors; but within that limit every function is doable. Also app support is great. Detailed and rapid. My experience is with iPad Pro 12.9 6th gen, Flex 6400, TGXL, and PGXL. I have used an iPhone 15 and it works remarkably well but I REALLY recommend the big iPad if you can. W0MPM
Decisamente pessima applicazione
Sono un radioamatore di lungo corso e molte volte sono solito scaricare queste applicazioni Sdrradio per testarle. Questa applicazione non sono riuscito a saperla usare, l'unica cosa che ho capito che si tratta di una finta voce registrata di un Qso Infatti se ascoltate attentamente sentirete ripetere la stessa identica frase a pappagallo, per coloro che non sanno come avviene veramente un Qso e pensasse che ciò che si sente qui è verità Vi dico che non è affatto vero Già disinstallata questa app inutile
Mehrfachinstallation?
Ich habe die App auf meinem iPad installiert. Jetzt wollte ich es auch noch auf meinem iPhone und dem iPad meiner Frau installieren, habe aber keine Möglichkeit gefunden, ohne weiter Zahlung. Normalerweise kann man doch eine App bis zu 5 mal installieren....?
crash after upgrade to new version 1.0.7
crash after upgrade to version 1.0.7 on ip6 with iOS 9.3.2
Incredible app
Quite impressive with everything that’s been built in to this one app. The fact you can do CW, FT8, and more right in the app is a huge accomplishment. I literally just tried FT8 for the first time from my iPhone while laying in bed. Would love (and would pay) for the ability to do Winlink from the app somehow. If not that, at least a mode like JS8, RTYY, etc where you could do some messaging. Hats off to the developers!
$60+ App
Be advised, this app is absolutely useless until you spend $60 to unlock it. You can’t even test it out first.
Almost perfect
I love this app and it works well. I only wish that the app also supported encode and decode of some basic digital modes like Olivia, PSK31 and RTTY. I would happily pay for the additional capabilities.
Love It
I purchased this program a couple of years ago for the novelty of being able to remotely operate my Flex radio, the reality is it has been one of my best software purchases to date. If you are chasing DX, parks or fill in the blank, some times your opportunity may not come at a time when you’re sitting in front of your radio. I have worked hundreds of contacts from the hotel room on a business trip or I got a Ham Alert notification that a person, park, or state has been spotted and I am on frequency in short order throwing out my call regardless of where I am physically located.
No sirve para nada.
Es una cosa que siempre repite lo mismo, no es sdr radio, es ina especie de anuncio que lo unico que hace es molestar y ocupar espacio. Muy malo.
IOS 18 Update
I was happy to see that the app worked flawlessly after my IPhone 14 upgrade to IOS 18. Great work by the developer to keep the app up to date. He has always been responsive to help needs via the help section in the app. If you have issues, it will direct you to him via email. Great program.
Can't try it
Downloaded to try. Can't try it without purchasing. Not worth it to me. I would like to try it first. They should give a full trial for 30 days.
Great Software for FlexRadio on IOS
I find this IOS software for FlexRadio on iPad and iPhone Pro MAX that I have is easier to configure and use for FT8 and SSB then on my Windows 11 Computer. I use it every day. I have made 114 confirmed DXCC/LoTW countries on FT8/FT4 since September 2022, and it is now Jan 30, 2023. This software is will worth the money spent to enable the features I use, including general radio access, the logging and,FT8 features. The developer has quickly answered questions to help with any problems I have in using the software.
Remote Operating At It’s Best
I bought a Flex 6400M with idea of operating it remote when we were out RVing. The radio is great and the pc software works great too. But I have a tether speed limit of 5 Mbps and was concerned that would not handle the radio data very well. The iPhone version works so well that I use a HDMI cable to the 50” tv and I am enjoying the hobby on the road without putting up additional antennas. The software works great! The sound quality through my V1 airpods is superb too. I’m super happy with the software and highly recommend it. 73s KJ5WO
