Fortunately, most modern radios have both of these. Interface, a way to get receive audio from the radio into a computer andĪudio output of the computer into the radio, typically a sound card interfaceĬapable of running the FT8 software and time synchronizationĪlthough 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. FT8 is also extremely popular on the 6 meter band, so there are many opportunities for long-distance communication even with a Technician Class License. With FT8, activity is limited to a narrow band of frequencies, so it is ideal for use with loop antennas that require retuning when changing frequency, such as CHAMELEON ANTENNA F-Loop 2.0 Portable HF Antenna ( CHA-F-LOOP-2-0). With its popularity, quickly working DXCC or WAS with FT8 is easily within reach of almost any station. This means that even low-powered stations and stations with sub-optimal antennas can make contacts worldwide. Why would I want toįT8 is designed to maximize communication even when signals are very weak (as low as -24dB). 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. and even older hardware-based modes such as RTTY that we now use our computers to encode and decode.
Message into audio tones that are sent out via your sound card to your radio’sįor years there have been a variety of these new software modes including Phase-shift keying (PSK31 & PSK 65), Hellschreiber, Olivia, Pactor, etc. Conversely, when you want to transmit, the software encodes your Radio to be processed by software to decode the information embedded in the (SCM) because they utilize a computer’s sound card to bring in audio from your
Wondering how to get started and why you would want to?įT8 is one of the many digital modes often referred to as sound card modes As one of theįastest growing modes of Amateur Radio it has been hard to miss, but you may be I am guessing that most of you reading this have either heardĪbout FT8 from fellow Hams or heard it on air as that strange repetitiveīuzzing sound between the CW and SSB portions of the bands.
