Digital Communications Modes

Amateur radio supports many modes of communication from morse code to voice to digital or computer-to-computer communications. Orange County, Florida Auxiliary Communications operates and maintains several APRS digipeaters around the county on 144.390MHz.

Our members are also active on PSK31, SEDAN and Winlink 2000. We use these capabilities to communicate between our Emergency Operations Center (EOC) and shelters as well as the state EOC when necessary.

A Winlink 2000 TelPac node, W4MCO-10, was installed at the Orange County EOC Radio Tower on May 22, 2006.

A Sedan Node on 145.770MHz was installed at the MCO airport, Oct 2006.
The callsign of the SEDAN node is: N2DB-3 Alias ORL.
The second Sedan Node went live, Nov 2006, in Ocoee.
The callsign of the second SEDAN node is: N2DB-1 Alias OCOEE.
This places nodes into the south eastern and north western corners of the county.

Our APRS digipeater W4MCO-10 is located at approximately the same location as the TelPac node, but at approximately 40 feet above ground level.
