Encyclopedia
WINMOR is a radio
transmission protocol intended to be used in the Winlink
2000 Global Radio E-mail System by amateur radio
operators, marine radio stations, and radio stations in isolated areas. WINMOR will complement the PACTOR
modes in the high frequency
portion of the Winlink
system. WINMOR debuted at the 2008 ARRL / TAPR
Digital Communications Conference. Unlike PACTOR II & III, only a simple computer soundcard-to-radio interface is required, as compared to PACTOR's relatively expensive external terminal node controller
. It has two modes, either 500 or 1600 hertz
in bandwidth, and provides ARQ speeds ranging from 67 to at least 1300 bits per second, similar to PACTOR's various modes. It is fully documented and without restrictions or license issues preventing anyone from using the protocol in other software. WINMOR supports both connected (ARQ) and FEC (broadcast) modes.
Operational peer-to-peer (on-air) beta testing of WINMOR began on September 17, 2009. Deployment of RMS WINMOR servers for the Winlink system began in January 2010.
Radio
Radio is the transmission of signals through free space by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space...

PACTOR
PACTOR is a radio modulation mode used by amateur radio operators, marine radio stations, and radio stations in isolated areas to send and receive digital information via radio. A robust network of PACTOR stations has been established to relay data between radio stations and the Internet,...

High frequency
High frequency radio frequencies are between 3 and 30 MHz. Also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters . Frequencies immediately below HF are denoted Medium-frequency , and the next higher frequencies are known as Very high frequency...

Terminal node controller
A terminal node controller is a device used by amateur radio operators to participate in AX.25 packet radio networks. It is similar in function to the Packet Assembler/Disassemblers used on X.25 networks, with the addition of a modem to convert baseband digital signals to audio tones.The TNC was...

Hertz
The hertz is the SI unit of frequency defined as the number of cycles per second of a periodic phenomenon. One of its most common uses is the description of the sine wave, particularly those used in radio and audio applications....
