what frequency is ft8

What is FT8?

•FT8 is an excellent mode for HF DXing and for situations like multi-hop Es on 6 meters, where deep QSB may make fast and reliable completion of QSOs desirable. •Works well for EME (“moonbounce”), meteor scatter and other modes where Doppler shift would otherwise render communications difficult or impossible SWOT Analysis1 Strengths Weaknesses

What kind of clock do you use for FT8?

A computer’s onboard clock can be notorious for drifting off, and FT8 needs to transmit at very specific times to work. That means that you need your clock to be accurate to the precise second. I use the Dimension 4 for keeping my clock accurate.

Is FT8 the most popular data mode?

In 2017, FT8 started to become the most popular of the various data modes. 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.

Can I operate FT8 with an older transceiver?

Although you can operate FT8 with older transceivers, the best experience will come by using a transceiver capable of both computer control and dedicated data mode. Fortunately, most modern radios have both of these. The extra feature that many of today’s radios have is a built-in sound card, eliminating the need for the extra sound card interface.

What is the 2 meter FT8 frequency?

2m FT8 has amazed me. This is a fairly new digital mode that was introduced in 2017 (I think) and has really "taken off". It is part of the free WSJT-X software suite. Signals only occupy about 50Hz and the TX periods are just 15 seconds long.

What are RTTY frequencies?

This is a radio receiver pre-tuned to 4 frequencies - 4583 kHz, 7646 kHz, 10100,8 kHz and 11039 kHz.

What is FT8 protocol?

FT4 and FT8 are digital protocols designed for rapid and accurate communication between amateur radio stations, particularly in weak- signal conditions. Information exchanged in a minimal two-station contact typically consists of call signs, four-character Maidenhead locators, signal reports, and acknowledgments.

Is FT8 upper or lower sideband?

When we think of "Band," we're usually talking about, say, the 40M band, or, at least, the cw, data or voice portions of it. But FT8 is an extremely narrowband mode, around 50 Hz wide. In the case of 40M, you set your radio to upper sideband (yes, upper, even on 40M and 80M) and tune it to 7074 kHz.

How do I get RTTY signals?

RTTY signals can be found on all HF bands - check the band plans and tune through the "Digital Modes" segments. A number of different modes are used in these band segments, but these modes can be distinguished by ear: RTTY signals are characterised by a regular shifting back and forth between two tone frequencies.

What is the most popular ham radio digital mode?

FT8 -when hams worked out techniques of connecting mechanical Teletype keyboard/printers to amateur gear using FSK and AFSK modulation. There are too many different modes to list individually, but here are some of the major ones: FT8 - In 2018 it is by far the most popular digital mode for award chasing and working DX.

What equipment is needed for FT8?

To use FT8 you need four things: An HF transceiver with data or SSB capability. An audio interface, a way to get receive audio from the radio into a computer and audio output of the computer into the radio, typically a sound card interface. A computer capable of running the FT8 software and time synchronization.

Is FT8 SSB?

It appears that although FT8 and other WSJT modes are going strong, the essential life-blood of amateur radio still continues to be the SSB radiotelephony and CW which are doing absolutely fine. There is a healthy and sustained growth of these core radio communication modes on the amateur radio HF bands.

What is FT8 radio?

FT8 is an extremely-weak-signal amateur radio mode that transmits very limited communications. JS8, a variant of FT8, can send full conversations and relay messages.

What is the FT8 signal?

FT8 transmissions can be decoded at S/N down to -21dB (very weak signal). FT8 was developed by Joe Taylor (K1JT) and Steve Franke (K9AN). It is one of the modes included in the open-source, weak signal, ham radio software package, WSJT-X.

What is JS8 in FT8?

JS8 is a variant of FT8 which allows operators to send more information and converse with each other. 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).

Is FT8 a conversation mode?

Because only this information can be sent, FT8 is not a "conversation" mode. FT8 transmits this minimum of information in a semi-automated fashion on its own time frame. Therefore, FT8 is not a "keyboard-to-keyboard" (real-time chat) mode.

What is FT8 mode?

FT8 is one of the many digital modes often referred to as sound card modes (SCM) because they utilize a computer’s sound card to bring in audio from your radio to be processed by software to decode the information embedded in the signal.

What is FT8 keying?

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 is a HF transceiver?

An audio interface, a way to get receive audio from the radio into a computer and audio output of the computer into the radio, typically a sound card interface. A computer capable of running the FT8 software and time synchronization. FT8 software.

What is the best software for FT8?

WSJT-X is the most popular software for FT8. This great program is not only free but versions are available for Windows-based PCs and Macintosh OS, Linux (with pre-compiled Debian, Fedora and Raspbian distros). For details on installing and configuring the software, follow the online WSJT-X User Guide. Do not ignore the information on making sure your computer’s time is synchronized as this is vital to making contacts! After you install the software, you may also need to configure your radio’s settings.

What is FT8 data mode?

FT8 – The Basics Explained. In 2017, FT8 started to become the most popular of the various data modes. At the time of writing (Feb 2018), it appears to be the most popular for a number of reasons: It’s fairly simple to set up. It’s significantly faster than the similar JT-65. It works very well even with a lot of noise.

What is WSJT X?

WSJT-X Settings screen (audio) Radio interface settings – Most common models of radio already have their comms settings built-in to WSJT-X, so it’s a case of selecting from a list of radios. Connecting to the radio’s CAT/DATA port for controlling the radio.

Does WSJT-X have a clock?

WSJT-X Settings screen ( radio / PTT) Your computer’s clock does have to be spot on with FT 8. A computer’s onboard clock can be notorious for drifting off, and FT8 needs to transmit at very specific times to work. That means that you need your clock to be accurate to the precise second.

When was amateur radio first used?

The latter is part of the basic framework upon which amateur radio was originally established, when back in 1914, the ARRL described in their 'Code of Conduct' for amateurs ... " The Amateur is Gentlemanly. He never knowingly uses the air for his own amusement in such a way as to lessen the pleasure of others.".

Can you hear 6m with a small antenna?

If you are a new arrival, with a small or makeshift antenna for 6m, it's important to realize that you may not be hearing what others near you (with bigger antennas) are hearing and can easily mess things up when transmitting at the wrong time. On HF, one can transmit or listen on whatever time sequence they wish.

What is FT8 mode?

Until fairly recently, FT8 was a mode that was something that one could indeed be indifferent to — it used a well-defined set of frequencies, and occupied very little bandwidth, essentially the equivalent of one SSB channel. You knew where to stay away from if you wanted to operate CW or another digital mode.

Is FT8 a spectrum hog?

FT8 is not a spectrum hog: it only takes a few kHz to support hundreds of stations simultaneously. Not needed: headset, micophone, key, speaker any power speak of. There are thousands of hams stuck in their tiny apartments with low power rigs and simple indoor wires who are now ejoying communications (if you want to call it that) with others.

Is FT8 bad for amateur radio?

The FT8 mode itself is not bad technology, or detriment al to amateur radio. The mindless fashion in which it is in use I’m not so sure about. This article was originally posted on Radio Artisan. Anthony, K3NG, is a regular contributor to AmateurRadio.com.
