FT8RX – FT8 Decoder Apk


This app quot;FT8RXquot; allows your telephone to decode the digital ham radio mode quot;FT8quot;. It only decodes, its not an encoder, you may simplest pay attention. If you dont know approximately FT8 I advocate getting familiar with WSJT-X from Joe Taylor first, which is likewise loose. You can also read the section quot;Before you buyquot; at the bottom of this text.

Decode FT8 to your smartphone!

FT8RX is a FT8 decoder for ham radio that doesnt require a PC or every other device to function. It facts audio input and tries to locate and decode FT8 alerts each 15 seconds. An internet connection isn’t always required (besides in case you need to synchronize to Internet time thru NTP, of direction).


Timing have to be correct so as for FT8 to work. Even even though smartphones usually synchronize their clock mechanically with the Internet, it still is a touch bit off occasionally. For this cause FT8RX has a put off capability, an inner clock, one should say, which can be used to in addition song the time shift.

Open the app and it’s going to begin looking for FT8 signals. You can test that the app is receiving audio by means of searching on the sound meter subsequent to the little microphone icon at the pinnacle or sincerely with the aid of looking at the waterfall diagram to the lowest.

When the quot;Decodingquot; text at the bottom proper lighting fixtures up the app is processing the most latest 15 seconds of audio facts. Results are displayed as fast as possible. If nothing might be decoded the decoding mild turns off and nothing receives displayed. Dont give up fast, getting the time settings proper may be problematic.

In case your phone clock is off by many seconds, strive the quot;NTP SYNCquot; button. It will connect to a NTP server and adjust FT8RX inner clock flow. Experience has shown that the obtained value from NTP is often still too inaccurate. In that case youll need to alter manually.

You can modify time closer to the offset of the incoming alerts by using pressing the quot;-zero.1squot; and quot; zero.1squot; buttons. If you see that every one alerts have a fine time waft, you must recall decreasing time drift by urgent quot;-0.

If you notice that maximum of the signals have a terrible time waft, you should use the quot; 0.1squot; button.

If you want to reset FT8RX clock actually press the quot;RESET Δtquot; button. You can see the cutting-edge offset for your smartphones clock within the decrease left corner. If it is zero, FT8RX is essentially the usage of your smartphones clock.

In case you dont get any effects, please talk to the trouble taking pictures manual related above.

Before you purchase / Implementation Notes

The app was evolved using the FT8 specification as defined through Joe Taylor in a piece of writing for the ARRL QEX magazine. Legally, Im no longer allowed to check the WSJT-X code for implementation info. Therefore, a few features are lacking on this app. Please take into account the following matters before buying this software:

1. The maximum worrying thing (at the least for me) is the absence of the 2500hz SNR dB size. I attempted to get the same results as WSJT-X and gave up on it in the end. Of course, calculating S/N become viable but yielded a one-of-a-kind price. To avoid confusion and false reviews I left it out completely.

2. WSJT-X is without a doubt the better decoder. Youll discover loads less indicators with FT8RX. So, despite the fact that it may occur that FT8RX determined a sign which WSJT-X did no longer (that’s rare), my assessments showed a performance of approximately 50% (as compared to WSJT-X).

three. Some (no longer so not unusual) FT8 modes are not (yet) supported:

– Type zero.1 DXpedition
– Type 0.3 Field Day
– Type zero.4 Field Day
– Type five EU VHF

four. No FT4 support: You cant encode or decode FT4 with this app.

five. You cant encode FT8. That approach, you cant create FT8 signals. You can simplest listen.

Final Remarks

Im open to tips and I desire youll have as plenty a laugh with it as I do.

seventy three, Sascha
