Ratings and reviews

I've had quite a few ham radio apps over the years, and usually they're kinda glitchy and are always lacking features. This app is completely the opposite! it worked straight away from the first time I connected it to my QMX and I kept discovering handy little features along the way that I didn't even know I wanted or needed. The ADIF export was dead simple and didn't need manual formatting. Just export, upload, and you're done. Thank you!

This is an Amazing app. thank You soo much Luis!!! The app is FREE and NO ads!!!! This app was designed for the QRPLabs rigs, I use it with the QMX. Most other apps have a lot of configuration and bugs and are difficult to set up and work. Because this was designed for the QRPLabs rigs there is actually no setup. You do need to enter your call, etc but no technical radio or phone settings. I literally just plugged in the usb cable to the rig and it worked!!!! interface is BEAUTIFUL THANKS

This FT8 app has native QMX support, displaying SWR and TX Power directly on the screen. It's significantly more performant than ft8cn or ft8tw, decoding more contacts and featuring a retry system that automatically re-attempts contacts after a few minutes. The app is very well thought out! It auto calls stations just finishing RR73 with another station and those actually calling CQ. What more could you want?

Performance improvements.
Fix to long callsigns in FT8/FT4/FT2 and JS8.
