Using Aprs And Echolink Simultaneously - Kenwood TM-255A Product Manual

7.6 Using APRS and EchoLink Simultaneously

Both EchoLink Sysop mode and APRS/Packet mode using the internal TNC can be used at the
same time. This means that a single TM-D710A/E transceiver can serve as an EchoLink node
station and APRS/Packet station to transmit beacons or work as a digipeater simultaneously.
To operate in EchoLink Sysop mode and use the APRS/Packet station with a single TM-D710A/E
transceiver, assign a different band for the external data band (Menu 517) for EchoLink and the
internal data band for Packet (Menu 529) or for APRS (Menu 601). For example, if B-band is
assigned for EchoLink, assign A-band for APRS/Packet mode. Since TM-D710A/E cannot
transmit on 2 frequencies at the same time, the transceiver transmits on the band on which a
transmission request comes first. If you wish to communicate between the internal TNC and a PC
for Packet mode operation, you will need another PG-5H programming cable kit in addition to the
PG-5H cable kit that is used for EchoLink Sysop mode.

7.6.1 Transmitting Node Information
Configure the EchoLink frequency in the transmit data for the QSY function. Configure the APRS
icon for EchoLink. Since data is transmitted using APRS with a beacon transmission, this will
send the EchoLink information.
