What can you do with a PACTOR modem?

PACTOR is a radio modulation mode used by amateur radio operators, marine radio stations, military or government users such as the US Department of Homeland Security, and radio stations in isolated areas to send and receive digital information via radio.

How fast is PACTOR 4?

PACTOR IV

Is packet radio still used?

Packet radio is an amateur radio technology from the early 1980s that sends data between computers. Linux has natively supported the packet radio protocol, more formally known as AX. 25, since 1993. Despite its age, amateur radio operators continue to use and develop packet radio today.

What is Vara HF?

VARA HF is a soundcard modem like ARDOP that can be commonly found on the HF bands exchanging traffic (Winlink). The creator of VARA is EA5HVK. Free version of VARA HF only allows tranfers up to ~180 bps, where as the paid version (70 USD) can allow transfers up to a max theoretical speed of ~8490 bps.

What does Pactor stand for?

What Does PACTOR Mean? PACTOR is a new form of data transmission that combines two prior methods called packet radio and AMTOR, a form of radio teletype messaging.

What can I do with packet radio?

Packet radio is a digital radio communications method used to send packets of data. Packet radio uses packet switching to transmit datagrams. This is very similar to how packets of data are transferred between nodes on the Internet. Packet radio can be used to transmit data long distances.

How much does Vara cost?

Free version of VARA HF only allows tranfers up to ~180 bps, where as the paid version (70 USD) can allow transfers up to a max theoretical speed of ~8490 bps.

How fast is Vara FM?

VARA is a software modem using orthogonal frequency-division multiplexing (OFDM) modulation. VARA is capable of HF speeds comparable with Pactor 3. It does this using 52 carriers limited to 42 bps thus satisfying the FCC symbol rate requirements of 300 baud or less for any carrier. VARA uses a bandwidth of 2400 Hz.

What is packet radio network?

Packet Radio (PR) represents the digital communications that use radio channels allocated to the amateur services. The name comes from the format in witch the data are send, called packets. This technology can be used to create inexpensive experimental radio networks.

Is VARA free?

How fast is VARA FM?

What does VARA cost?

What is VARA digital mode?

VARA is a High Performance HF modem based on OFDM modulation. VARA Modem, brings state of the art Military grade technology to new and existing HF data. Introduces a new standard of technology available for Amateur and Commercial use. Designed for operation within a SSB Bandwidth of 2400 Hz.

Is PSK31 the same as RTTY?

RTTY is a very simple binary frequency shift keying (BFSK) modulation scheme, and PSK31 is a very simple binary phase shift keying (BPSK) modulation scheme. FSK and PSK are very common modulation schemes for digital modes, and implementing the simple forms of these is key to implementing the more complex forms.

What is DM780?

Digital Master 780 (DM780) is the new Multi-Mode Digital Software Program from Ham Radio Deluxe. DM780 supports the most commonly used digital modes, including variations of: BPSK, QPSK, CW, MCW, RTTY, MFSK, Olivia, DominoEX, Throb, ThrobEX, MT63, with Hell, WJST, and others to come.
