I now have a new Windows 10 computer, loaded with the latest versions of WSJT-X (v2.2.2) and JTAlert (v2.16.17). This mode allows communicating with a lower s/n ratio compared to PSK31 or RTTY. I forgot how the software handles the ratio. By far the most useful weirdness is to shift-click on the waterfall to put your TX signal there (think of it as shift my TX). This ham radio digital mode appeared in 2017, and since then its popularity has only been growing. They are negative numbers (unless you are running too much power; Is there too much power? https://www.sigidwiki.com/index.php?title=FT8&oldid=20766, 3.573 MHz,7.074 MHz,10.136 MHz,14.074 MHz,24.915 MHz,50.323 MHz,70.1 MHz,144.174 MHz,1.84 MHz,18.1 MHz,21.074 MHz,28.074 MHz,50.313 MHz, FT8 is an extremely-weak-signal amateur radio mode that transmits very limited communications. 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. Welcome to Reddit's own amateur (ham) radio club. 15' on the transformer side and around 35' at the far end up in a tree. The only time I bump up to full power is if there's been QSB and the other station isn't copying my "RR73". Rich Text Editor. This includes: harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing. Until you're into the -20dBs you're being heard. Want to say thanks? UTC: When the signal was received, dB: Signal strength of the received signal in dB. Often this will be a separateCOM port that needs setting up in the software. To enable reporting, you need to enter the following information into the settings or preferences . I received services from the Prefet of the TAAF the new convention me allowing me to start my HF activities under the conditions set by the IPEV. Your antennas ability to direct that transmit power at the receiving station and. Very helpful. The mode is a modification of the JT9 & JT65 weak-signal modes that have been around for nearly ten years, an eternity in the digital world. Examples of non-digital reports would be: Different colors are different bands and minutes indicate the last time they heard and reported back automatically. 2023 A computers onboard clock can be notorious for drifting off, and FT8 needs to transmit at very specific times to work. Questions? All this is necessary because the maximum message length is 77 bits (not only predefined symbols but of course, arbitrary text and even telemetry can also be transmitted with similar limitations). the QSO record in ACL log does contain the signal report . Try lowering the AGC, if any, and/or the output audio level. All this, combined together, made FT8 so popular. FT8 is designed to maximize communication even when signals are very weak (as low as -24dB). Some use the S-Meter on their radios to give the reading, which is fine if it is accurate (it is notusually as there are many factors) or by ear which frankly is a better way to go about it.

Best advice I can offer, is check pskreporter. 4. Personally, I dont really understand the pleasure of almost completely automatic radio communications, but the FT8 is popular, so people use this. Antenna for 70cms is a 7 ele ZLspecial, fixed towards SE up at about 15 feet. Yep I've been lucky enough to get Fiji x2 and Kenya in the past week or 2 so it's definitely working! Ham radio callsigns have a strictly defined format of letters and numbers, which also allows us to record them in a more compact form. Also, JTDX, which many of us use because it often decodes weak signals that WSJT-X misses, uses a different algorithm for computing that report (usually many dB lower). Alternatively, you can add the new FT8 frequencies manually. Lets try to figure it out. At first, just a fun fact. Forgot your password? It will gain acceptance in SOTA too. At this step, the message is converted to 00 00 00 23 44 4A 11 91 3F 8B 57 7E CF 78 77 39 55 DE 36 EF 01 48 data block. Why would I want to operate FT8? JS8Call (JS8) is an amateur radio QSO communication mode based on FT8. Having the sequence shown above, we can easily generate a WAV file or directly control the frequency synthesizer in the case of an autonomous beacon. CleanTalk sets this cookie to store dynamic variables from the browser. What do all the characters mean? FT8 transmits this minimum of information in a semi-automated fashion on its own time frame. GL, K7TRK. Information exchanged in a minimal two-station contact typically consists of call signs, four-character Maidenhead locators, signal reports, and acknowledgments. In amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range.

I am running . Hello, after years of saying I would never work FT8 I have finally taken the plunge and having a play. It's a good way to check the quality of your radio setup, and the radio propagation properties that depend on how grumpy the ionosphere is at the moment. 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. Free Help. 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.

Hit tab to get into that menu. No Membership Fees. If this is the case, then you probably have signal distortion in audio output. From a psychological point of view, the FT8 mode is also interesting to analyze. Automatic miles km. In the first step, common abbreviations are replaced by shorter codes, for example, CQ gets a 02h code. JTDX adds a number of FT8 decoding options that are useful on crowded bands and in situations when signals are very weak.

Hello, after years of saying I would never work FT8 I have finally taken the plunge and having a play. Because only this information can be sent, FT8 is not a "conversation" mode. Each FT8 transmission can support up to 13 text characters, coded using forward error correction to ensure proper transmission and decoding despite common radio effects such as fading, interference or poor signal propagation conditions, or low power operation with compromised antennas in restricted urban spaces. Antenna for 70cms is a 7 ele ZLspecial, fixed towards SE up at about 15 feet. Here is the generally accepted System: Basic rule: Higher Numbers are always better. Be sure to configure your software properly as described below. 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. I am running a full 100W into my radio. Transmissions occur in 12.6s intervals (within the 15s transmit cycle window) until an entire message has completed transmitting. No, I can't confirm that, I only use FT8. Of course, before the mass appearance of personal computers in homes, probably no radio amateurs were thinking about transmitting and decoding digital data. Noticed that now when a QSO is logged, the upload to eQSL.cc no longer includes the signal reports added to the comment field of the eQSL record (like FT8 Sent: -19 Rcvd: -07). Most likely your noise level is much lower than the station(s) you are working but I have also noticed a difference in the reports I give out depending which radio/AGC setting I am using. FT8 uses 8- GFSK modulation, includes forward error correction ( FEC ), and has an effective data rate of 5 words per minute. FT8 transmits and receives only the bare essentials needed to make an amateur radio contact (QSO): Exhange of callsigns, readability report, signal strength report, and "best regards" ("73"). However this is what makes Ham Radio so DAM interesting and fun!! On a trial basis, and in response to numerous suggestions from around the world, we have added a second set of suggested dial frequencies for FT8 on three HF bands and also on 6 meters. Many ops can compensate with more power, but the problem with that is you quickly exceed your receive capabilities - people can hear you but you cant hear them.

Grayed-out cells are commonly-used frequencies which are not included in the default program settings of JS8Call or WSJT-X (FT8). Frequency modulation 8-FSK, tone space is 6.25Hz. ND4Q starts QSO with signal report ND4Q does not send grid location Causes problems when working complex call signs 75 Sec per QSO, 48 QSOs per hour. It's main advantage is that it allows low-power stations with marginal Let's say I call CQ and a few stations respond, the first being pretty weak (call 1st enabled). FT8 is one of a group of Multiple Frequency-Shift Keying (MFSK) modes that include JT9, JT65 and MSK144 created by Joe Taylor, K1JT and co-developers. What says you are have a problem are things like. delphinium hybrid blue. 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. I consistently get low signal reports for FT8 contacts, typically 15db less than what I send as a received signal. 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. A lot of people hate FT8. Do not assume that many folks are running 100 watts or less. FT4 and FT8 are digital protocols designed for rapid and accurate communication between amateur radio stations, particularly in weak-signal conditions. ft8 signal reports explained.
