    Adesso posso completare il mio pulpito tx con questo utilissimo strumento consentendomi di monitorare sia il funzionamento corretto della mia tx che le frequenze degli altri modellisti presenti sul campo.Provata per adesso solo in laboratorio ma funziona che e' una meraviglia, per non parlare dell'effetto ottico che e' fenomenale!!!!!!

    This device will alert you to the presence of other signals in the 2.4 G range used by many drones for flight control. These can sometimes cause interference with the signals from the flight control transmitter. Since most drones can have the control frequencies reconfigured, if there is lots of activity on the upper part of this spectrum, you can change the control channels to a different portion of the spectrum that is less crowded. The device comes with a pigtail that plugs into the JST connector which you can solder to your power. I chose a 9 volt battery and added a On-Off switch to a case I made from discarded covers from Radio Shack project boxes. I used the case the Lantian came in to hold it. The scratch in that case is a little distracting, but it still makes a great holder for the spectrograph. Nothing else except the power needs to be added for this to work and produce the signals it can see. I made a short video and posted it on Vimeo at this link: Will try to post it here so it embeds, but I don't use Youtube so not sure I can do that.

    Very useful device to control the emission of its 2.4Ghz radio control connects to a 2S 8.4v lipo with JST socket Otherwise for deliveries, fast enough for delivery from China (Priority direct mail).

    Good cheap product, bought to control the flight zone of 2.4Ghz controlled radio models

    No adjustments just apply power and go No mounting holes Only way to mount would be with some sticky tape. Be careful of fragile ribbon cable on front List frequency along axis would be nice if there were actual channel numbers. Not very sensitive. Midrange reading only when touching controller

    Excellent petit appareil pour tester la fréquence et la puissance relative. Un prix dérisoire pour le service rendu. Parfait pour tout matériel réseau wifi et absolument indispensable pour tout pilote de drone !

    Great little gadget! 3D printed a case for it and it does exactly what it says it does. I have found that it works on 7.2v.

    quite too small it lacks a more precise display of frequencies but is usefull
