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. Power amps are unnecessary and unwanted on the FT8 band seqments. A well equipped FT8 station only requires 25-50 watts and a modest antenna. This means that even low-powered stations and stations with sub-optimal antennas can make contacts worldwide. 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.įT8 is designed to maximize communication even when signals are very weak (as low as -24dB). and even older hardware-based modes such as RTTY that we now use our computers to encode and decode.

Conversely, when you want to transmit, the software encodes your message into audio tones that are sent out via your sound card to your radio’s audio or Mic input.įor years there have been a variety of these new software modes including Phase-shift keying (PSK31 & PSK 65), Hellschreiber, Olivia, Pactor, etc.
FREE CW DECODER IC 7100 HOW TO
As one of the fastest growing modes of Amateur Radio it has been hard to miss, but you may be wondering how to get started and why you would want to.įirst, what is it? 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.
A lack of sunspots has turned HF CW and SSB into a dead zone for many of us who don’t operate super stations.
