Now, with FT8, I have real comparisons and can surely see a 5 - 10 db difference for most contacts. That means that you need your clock to be accurate to the precise second. 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. Its significantly faster than the similar JT-65, It works very well even with a lot of noise, Its popular, so theres lots of activity, Its semi-automated, making for easy contacts, Its a great way of racking up the countries youve worked, without too much hassle, Getting the audio connected. 73 Cliff W3KKO. ), or even compromised antennas. You are just very strong. The one on the right, being about 100Hz wide, is a second harmonic, and the one on the left, being about 150Hz wide, may be a third harmonic. timeout for worked markers. What are the frequencies? Thats what I do. It will gain acceptance in SOTA too. These features can be selectively enabled to match band and signal conditions as well as the user's available CPU horsepower. 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 - The Basics Explained | Essex Ham Examples of non-digital reports would 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. I even run the attenuator on 40M. Increasing FT8 usage on the popular bands 40, 30, and 20m means that the default 3 kHz sub-bands are often wall-to-wall with signals. I always thought, its likely because of a quiet location, a good radio (6600M) and maybe others running more power.

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. Operators may or may not be aware of the noise they're creating on the band's, but the result of that noise is is qrm for the others trying to operate on the same band . (Serial number sequencing for DX op's could be a challenge for those op's) The typical JT / FT8 signal report data would interchange nicely instead of RS (T) without any modifications. FT8 signal report Sent/Rcv consistent difference. 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. Both are compromises, but my FT8 contacts in Antarctica, Fiji, Australia, NZ, Japan, etc don't know that. Until you're into the -20dBs you're being heard. Antenna for 70cms is a 7 ele ZLspecial, fixed towards SE up at about 15 feet. From my playing I think this one is alc related. Free Help. It contains a hashed/encrypted unique ID. ft8 signal reports explained just mercy sinopsis maryland vacation payout at termination. Different colors are different bands and minutes indicate the last time they heard and reported back automatically. The higher the better when it comes to decoding, but generally you do not want to come back as positive unless it is a nearby station as this indicates you are running way too much power. Heck, I even see a difference in dB when running two slices off the same antenna. I got a + signal report back from one and a -18 or so back from the other. Essex Ham - Supporting Amateur Radio in Essex Typically S7 to S9+ on HF. . 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. Create an account to follow your favorite communities and start taking part in conversations.

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). 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). New chunks of messages arrive every 15 seconds, and are decoded by the WSJT-X software, which displays the messages like this: 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. It is calculated as the ratio of signal power to the noise power. Conclusion. A FT8 contact would be quite an undertaking. It's not an absolute scale. Automatic miles km. It works only in coordination with the primary cookie. 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. I think this violates the Terms of Service. As we can see, FT8 is quite an interesting protocol. Any other suggestions how to troubleshoot this? Personally, I dont really understand the pleasure of almost completely automatic radio communications, but the FT8 is popular, so people use this. The new topic will begin with this message. I can see on an external SWR meter that I am sending 100w. 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. 15' on the transformer side and around 35' at the far end up in a tree. Forgot your password? This runs in the background and keeps your clock in-sync by resetting the time to one of the online atomic clock servers every 20 minutes. I would think that is more than enough to get a decent signal report.
