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). People decoding you multiple times. For a successful QSO, which takes about 90 seconds, decodes occur 4 times a minute, 2 second break between cycles. Therefore, FT8 is not a "keyboard-to-keyboard" (real-time chat) mode. If nothing else, remember to shift-click .

I got a + signal report back from one and a -18 or so back from the other. Re: [CQ-Contest] Reciprocity in signal strength 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. FT8 is by nature < 50% duty cycle. All topics relating to the hobby are welcome here, from purchasing and building equipment, to operating techniques and activities, and everything in between.

Subject of the new topic: On average I run about 30 watts only on this mode and have had some success on 70cms along with the other bands. Thats what I do. Is there a solution? Welcome to JS8Call JS8Call is software using the JS8 Digital Mode providing weak signal keyboard to keyboard messaging to Amateur Radio Operators. This mode allows communicating with a lower s/n ratio compared to PSK31 or RTTY. This page was last modified on 14 April 2021, at 21:03. 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. Tell us more about your antenna system - antenna, feedline, any transmatch needed, etc. It is an ICOM feature, not a bug. JS8Call (JS8) is an amateur radio QSO communication mode based on FT8. I now have a new Windows 10 computer, loaded with the latest versions of WSJT-X (v2.2.2) and JTAlert (v2.16.17). Some operators do, some don't. 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. Just to report that quarantine in between I was able to pump some hours into the long delayed FT8 transceiver based on a raspberry pi using the RPiTX package and now ft8_lib. Welcome to the new FlexRadio Community! 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 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. IMO, focus on doing everything you can to improve your receive capabilities first with a focus on lowering your noise floor, then improve antenna transmit gain before adding power.

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"). 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. The exchange above would therefore take about 90 seconds (compared with seven minutes on JT65). This cookie, set by Cloudflare, is used to support Cloudflare Bot Management.

The numbers tell you the strength of your FSK signal (6.25 Hz) as it compares to the signals in an entire 2.5 kHz SSB bandwidth. This is measurable to some extent by the signal reports on FT8. It's a popular mode, so popular in fact that one report citing Club Log data recently showed that 80% of HF contacts in their tracking nowadays are FT8. Alternatively, you can add the new FT8 frequencies manually. 2023 If theres any interest, Im happy to expend this article, but hopefully this tells you what FT8 is all about, and gives you enough to get started.

The idea of replacing characters with indexes is important here, which is effective when using a small dictionary size. 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. I am using Windows 10 with WSJT-X v2.5.3 with a USB connection to an iCom 7610 transceiver running 100w. Maybe invest in antenna & pre-amp. Sometimes propagation is like a laser.
