About TXAdvance
TxAdvance is a radio frequency transmitter manager that helps you quickly get the best frequencies by scanning the RF spectrum and automatically calculating the intermodulations products of your selected frequencies.
Radio frequency spectrum
The RF scan is using the Software Defined Radio technology which allows quick and precise scan. Just plug a compatible* and inexpensive SDR USB dongle to your phone to start analyzing any part of the RF spectrum from 50 to 1300 MHz with a 5 kHz resolution.
Transmitters coordination
Make sure that all of your transmitters are free of any of intermodulation (2TX3order, 2TX5order, 2TX7order and 3TX3order). Calculation and analysis is automatic.
For each transmitter, you can see its available channels with the amount of noise and the intermodulation status.
You can coordinate an unlimited amount of transmitters from any brand.
Auto mode
TXAdvance can automatically find the best frequencies for your transmitters by analyzing the RF spectrum and avoid intermodulation products.
You can also choose your frequencies manually.
Live Check
Turn your Android device into a Real-Time RF Analyzer.
TXAdvance Scan Exchange - TASE
A collaborative worldwide map of scans : anticipate your wireless transmitters coordination by downloading and importing geo-tagged and time-stamped RF spectrum scans from all over the world.
Upload scans directly from TXAdvance to the TASE.
Exclusions lists
User can set bands of frequencies to avoid. It can be TV channels or any custom bands.
Import / Export
Scans and lists of transmitters can be exported and imported for back-up or sharing purposes in proprietary TXA format or CSV format for import in third-party softwares.
To use TXAdvance, you will need :
- an Android phone with OTG support running at least Android 6.0
- an SDR USB dongle with a RTL2832U chipset and R820T2 tuner such as the RTL-SDR blog v3 (Many other models exist)

User reviews
It's an essential app if you work in the film and television industry. It's a small lightweight tool that allows you to scan frequencies and allocate radio mics without the need of a laptop or a large cumbersome scanner. Excited about the updates to the app as well.
Brilliant app just what I was looking for. MAKE SURE your tablet actually does OTG before you try it and you will do well.
This is a fantastic program for frequency scanning and coordination. Didn't have a compatible device, so I purchased a cheap new android phone, along with a compatible SDR dongle and OTG cable. Even with the additional expense of hardware, it still cost me less than comparable portable scanners, all while providing ...
Wonderfully app with very flexible developer.
Great Sound Mixers Tool
I've only started using TXAdvance but so far it's been a great help.
