If you are primarily doing FT8 or some other digital mode and not phone, then you will be fine though. In the non-digital modes you can add multiple connections inbound and outbound and they are all bridged together. It is one of the most common and easy-to-use digital modes as a PSK31 station needs only to consist of an SSB transceiver, an antenna, and a sound-card equipped PC. There are various modes such as XSL, TADIL, HFDL, Pactor, CW, HF Fax, Packet, JT, ALE, DRM, RTTY and various OFDM schemes. The HF Digital "Tower of Babel" QST January 2001, pp. It’s popular because of its narrow signal. Most signals are received and recorded using a software defined radio such as the RTL-SDR, Airspy, SDRPlay, HackRF, BladeRF, Funcube Dongle, USRP and other devices. While a robust mode, it only has 5 bits (as did its predecessor RTTY) and can not transfer extended ASCII or any binary data. Still others are specialized for extremely weak signals, such as moon-bounce. Keep in mind that if you do go in there and no one answers your question, despite there being a couple dozen names in the room, it does not mean anyone is ignoring you.
