What is JT9?

JT9 is a very narrow 9-FSK mode for making contact (QSO’s) under extreme weak-signal conditions. JT9 is about 2 dB more sensitive than JT65A while using less than 10% of the bandwidth.

What is PSK31 in ham radio?

PSK31 or “Phase Shift Keying, 31 Baud”, also BPSK31 and QPSK31, is a popular computer-sound card-generated radioteletype mode, used primarily by amateur radio operators to conduct real-time keyboard-to-keyboard chat, most often using frequencies in the high frequency amateur radio bands (near-shortwave).

What is JT65?

JT65 is a digital protocol intended for Amateur Radio communication with extremely weak signals. It was designed to optimize Earth-Moon-Earth (EME) contacts on the VHF bands, and conforms efficiently to the established standards and procedures for such QSOs.

What does BPSK 31 sound like?

A PSK31 signal just sounds like a single tone or note with a slight wobble and is used for real-time keyboard-to-keyboard informal text “chats” over the air. It works very well with low power levels and for this reason it has become a firm favourite for QRP and stealth antenna operators.

What do I need to run 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.

What is ham mode phone?

For example, the term “phone” refers to using your voice on the radio. Hence, you will hear hams referring to “phone mode” or “the phone modes,” meaning an operation in which the operator is speaking into a microphone and pumping voice signal out over the airwaves.

What is HamScope?

HamScope is a digital communications interface that supports many modes including PSK31, RTTY, MFSK16 and packet (both HF and VHF). To run packet, HamScope ‘connects’ to an AGWPE ‘port’. AGWPE does all the communication with the sound card or TNC for HamScope.
