But the computer processing power grew up, and finally, the hero of our article appeared the digital mode FT8. What says you are have a problem are things like. But I do look at a lot of FT8 op QRZ profiles of people running an Icom 7300 to some freakishly compromise setup. hihi I jest. 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. You all have seen it in social media and on the air. These frequencies will appear in your drop-down band-selector list after you go to the Settings/Frequencies tab, right-click on the frequency table, and select Reset. I am not sure how easy it is to measure the output power at the SteppIR, but I could measure power at the bottom of the antenna. AE6Y will be active again as P49Y from Aruba Island, IOTA SA - 036, in ARRL DX CW Contest, 18 - 19 February 2023. The message length is 15s, and messages are transmitted via fixed time slots, which makes decoding easier. Is there a setting that I am missing somewhere to fix this problem. So, its interesting to see the future evolution of the ham radio digital modes. Any suggestions on what the problem might be? Since FT8 automatically transmits and receives only the bare minimum of information necessary to complete what officially counts as an amateur radio contact (QSO), FT8 has been criticized by some amateur radio enthusiasts as a means for radio amateurs to 'cheat' their way to victory in certain contests and award categories. 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. A good test bed is WSPR. It is popular among amateur radio operators for its ability to send signals despite challenging propagation conditions, high noise environments, low power operations (QRPIn amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range.

Similarly, the JO62 grid-locator is written as a 2-byte number 44 FE 50% save of the data size, compared to the standard ASCII string. It is one of the modes included in the open-source, weak signal, ham radio software package, WSJT-X. Probably everyone who is at least a bit interested in amateur radio and telecommunications heard about the FT8 digital communication protocol. AH2R Team will be active from Guam Island, IOTA OC - 026, in ARRL DX SSB Contest, 4 - 5 March 2023. Forgot your username? JS8Call turns FT8 into a "chat" mode, allowing stations . For FT8 and many other digital modes (But not RTTY), the values are measured by the software and are expressed in dB such as -10 or +02 for example. I run QRP and most of the time the reports are like above, I put 5W into the antenna, they put 100+ (and some Italians would do multi-kW).

A +12 signal does not say you are splattering. Your transmit and receive capabilities are not that much different. toggle quoted message Show quoted text Special data for synchronization (7x7 Costas Array) is also added, it requires for proper signal decoding. You can also setup your WSJT-X and other digital software to send reports back so you can analyze your own receives over a period of time or assist others in analyzing propagation. FT8 is by nature < 50% duty cycle. Any other suggestions how to troubleshoot this? But this is my personal opinion. On average I run about 30 watts only on this mode and have had some success on 70cms along with the other bands. Press question mark to learn the rest of the keyboard shortcuts. Forgot your password? ), or even compromised antennas. FT8 handles very weak signals very well, meaning that a Foundation licence holder with just 10 watts should be able to make some impressive contacts with a modest antenna - something not possible with voice or some other data modes. This includes: harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing. 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. I noticed for a while that I can hear better than I am being heard. 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. First number is for Readability (R), the second is for Strength (S), and the last one is for Tone (T) when representing CW signals. It includes integration with PSK reporter. I am using Windows 10 with WSJT-X v2.5.3 with a USB connection to an iCom 7610 . There are several types of interface available, depending on your rig. It's a shame that most people don't understand that FT8 is designed for weak signal communication. In log 80k QSOs.Problems with low bands. Donation will show as going to SFBA Tech, this is normal, under the same paypal account. It was specifically created to work well in really bad situations like meteor scatter or moonbounce.

If a received CW signal is S9 and the meter reads S7 without a signal, the SNR is 12dB (normally each S-unit is 6dB).

I feed the IQ output of my 7610 into HDSDR and then feed the audio out of HDSDR into WSJT-X through a virtual audio feed.

Replied by G0CBOon topic FT8 Signal Reports Many Thanks for the link James, explains it well, a useful chart that gives the scale. Create an account. No, I can't confirm that, I only use FT8. SNR(dB) = 10*LOG[ Signal Power in watts / Noise Power in Watts] For loud signals you can roughly calculate SNR off the S-meter. The radio also needs to be in DATA mode. DT: Calculated offset of the received signal from your local clock Values above .3 are not optimal. A WSJT-X application screenshot in FT8 mode looks like this: Source: 3fs.net.au/ft8-digital-amateur-radio. Groups.io. If you and your next door neighbor were running FT8 at the same time, with perfectly tuned and adjusted 30 watt rigs, you can be sure that you'd both be "splattering" all over the place. We must say that technically these digital modes are simple, and the characters, entered by the user, were broadcasted almost without any complicated processing. If I tighten the passband in HDSDR down to like 100hz around the signal of interest, there's virtually no other noise in the WSJT-X passband. (Sources: WSJT-X 2.1.0 Program default settings, DXZone, WSJT-X Documentation, JS8Call Documentation). When I run FT-8 I set the filter wide open which bumps up to the 15Khz roofing filter instead of the ~3Khz SSB filter.

SNR is expressed in dB (decibles). JS8Call (JS8) is an amateur radio QSO communication mode based on FT8. Right now my antenna is set up as a sloper. Each message of up to 13 characters takes 13 seconds to send. The exchange above would therefore take about 90 seconds (compared with seven minutes on JT65). So, the signal reports dont make any sense. 1995-2021 Lucas Ford / W6AER / SFBA Tech (Formerly Dream Flix Productions) - ALL RIGHTS RESERVED - - Hosted by QTH.com.

There are 4 slots per minute, and you transmit for one 15 second block, then listen for replies for 15 seconds, and transmit again for 15 seconds. When I last had a play the lower the alc the smaller the spurs at each tone change. 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. Then, youll need some software. However this is what makes Ham Radio so DAM interesting and fun!! Why are the signal reports negative numbers? 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 Radio operator "IZ1M" replies with his callsign and grid square locator. - Lucas / W6AER.
