Tolle App

Wirklich schöne App - funktional und wird immer wieder optimiert und weiter entwickelt - dieser Punkt ist für mich besonders wichtig - würde die App definitiv wieder erwerben - ganz klar geschenkt ist die App nicht - aber ihr Preis ist sie Wert

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.

Awesome App

I find myself listening through the app more than on my Flex Radio.

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!

SmartSDR

Excellent App ‘6’ Stars. I recently had a problem with my logbook and Marcus couldn’t have been more helpful in resolving the issue. He went above and beyond my expectation in doing this. Thank you Marcus.
