ft8 signal reports explained

This signal is transmitted almost "as is" into the air, and the backward process of decoding is activated on the receiver side. The other thing to keep in mind is that signal level is relative to the noise level around the signal. Now, with FT8, I have real comparisons and can surely see a 5 - 10 db difference for most contacts. Common to receive say a European station after their dusk but nothing you can do to make them hear you. Free Training. During contest and for DX Expeditions everyone is 59 for Phone (USB/LSB) ad 5NN for CW in order to expedite exchange. Is there a setting that I am missing somewhere to fix this problem.

Hertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). FT8 and its Decibels Editorial section of the Monthly FB NEWS magazine We have received reports that we are seeing signs of sun spot cycle 25, but it still has been difficult to hear overseas stations on SSB or CW.

When the conventional FT8 sub-band on 6, 20, 30, or 40m seems too full, please try moving your dial frequency down 3 kHz! I primarily run FT8 at 30W into either a 135ft long end fed at about 40ft, or a vertical delta loop with apex around 40ft but base at 6ft. Pending some tweaking and other optimizations I've a version running using the library right out of the air, receiver SDR is a rtl-sdr dongle.

If you want to, fine, but absolutely not necessary to run 1 watt or less.lol.. IMHO your results are just fine. I will be starting a donor thank you page soon so please indicate if you wish to be not listed. FT8 ("Franke-Taylor design, 8-FSK modulation") is an extremely-weak-signal, digital, narrow bandwidth (50 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). MOD input should only listen to you PC of course. wire The following equations explain why FT8 signals start decoding at -26dB and everything else is below the noise floor: SNRFSKFT8 = SNRreportedFT8 + (10 x LOG (2500 Hz/6.250 Hz)) JS8 was created to allow the basic principles of FT8 to be applied to sending actual messages (instead of just the bare minimum QSO information that FT8 limits operators with). Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. I noticed for a while that I can hear better than I am being heard. Essex Ham is dedicated to supporting Amateur Radio. Personally, I dont really understand the pleasure of almost completely automatic radio communications, but the FT8 is popular, so people use this.

Starting with theWSJT-Xversion 2.2.0-rc2 (available for downloading from theWSJT-X website) theWSJT-Xdevelopment team has also published additional FT8 overflow frequencies: 7.071, 10.133, 14.071, and 50.310 MHz. Other amateur radio operators herald the mode as a boon to the hobby of amateur radio during times when the solar cycle is at a minimum and when radio propagation conditions are poor. FT8 is a weak signal - not a low power mode (power works the really weak ones) FT8 lets you work DX on 6m when there would be none FT8 is suddenly dominating VHF/UHF contesting FT8 lets you work weak signal DX without proficient CW skills FT8 is like having constant DX beacons on every band By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform.

Do not assume that many folks are running 100 watts or less. Signal reports for FT-8 can vary by 10dB or more between cycles due to fading and changing polarization. Automatic miles km.

We are trying to coordinate the suggested frequencies in WSJT-X with updated band plans being considered by IARU, ARRL, and other amateur radio societies. Here's the actual math behind the signal report if you want to deep dive into the concept: The noise floor is relative to the receiving station, however. On Tue, Jan 4, 2022 at 7:15 AM John wrote: Are you sure you wish to delete this message from the message archives of main@WSJTX.groups.io? Some of these I see the images spaced at twice their mains power frequency. That being said, it just means you are coming in loud at the receiving location. A +12 signal at times says more about the other persons low noise floor than whether you maybe a strong signal. Share them in the comments below or email me at KE8FMJ@arrl.net. The only time I bump up to full power is if there's been QSB and the other station isn't copying my "RR73". From DXNews.com, 59 plus 20 for a really strong USB signal, 47 for a somewhat weak but still readable USB signal. As a result, the signal report I end up giving is like 30dB higher than it would be if I left the entire passband open. ), or even compromised antennas.

If you are wondering what Amateur Radio is about, it's basically a two way radio service where licensed operators throughout the world experiment and communicate with each other on frequencies reserved for license holders. FT8 transmissions can be decoded at S/N down to -21dB (very weak signal). It is one of the modes included in the open-source, weak signal, ham radio software package, WSJT-X. (references). shift/alt/control keys and clicks are handily explained on the screen by pressing F5 to ^Display special mouse commands _ (commands for special mice): 3. I always thought, its likely because of a quiet location, a good radio (6600M) and maybe others running more power. With the bonus of DAX not requiring A/D conversion and the attendant degradation of received signals, your great installation, radio, and location really do put you ahead of the average Joe. FT8 signal report Sent/Rcv consistent difference. Heres the actual math behind the signal report if you want to deep dive into the concept: The noise floor is relative to the receiving station, however.

These modes, while great for modest stations (read . That means that you need your clock to be accurate to the precise second. Some operators do, some don't. FT8 transmissions can be decoded at S/N down to -21dB (very weak signal). If the average recipient has a lot more noise than you, you will get a worse report on average. Here you will see that on my FT8 Transmit some decoded me as +13 and others closer as -3, this can be due to skip zones as well as different antenna setups, etc. At the time of writing (Feb 2018), it appears to be the most popular for a number of reasons: As with modes such as JT65 and PSK31, you interface your HF rig to a computer, and send out text encoded by your computer over the amateur bands.
