License-Free Radio Modems
Radio modems come in pairs, each composed of two similar
units that can indifferently be used at the base or the rover.
The radio modem used at the base will automatically become
a transmitter while the other one, used at the rover, will automatically operate as a receiver.
Models. Radio modems come in two different models. One is
for use in North America (NA) (P/N111360), and the other
(P/N 111359) is intended for most European countries (EU)
(except Italy, Slovak Republic and Bulgaria) (This information
is subject to change without notice). The table below gives the
main features of the two models.

Frequency channels. Radio modems are plug-and-play units.
They are all factory-set to operate on their first channel (channel #0). If however the default transmission channel is
jammed in your working area, you can select another transmission channel using the Radio Configuration utility (see Radio
Configuration on page 255). Don’t forget in that case to
change the channel on both units.
Frequency hopping in the NA model. The selected channel
corresponds to the first channel on which the radio transmits/
receives.
RTCM Rate in the EU Model. In the European Union, licensefree radios are allowed to transmit only 10% of the time. To
be sure this requirement is always met, Magellan recommends
that you set the RTCM rate to 2 seconds. Using “1 second” is
not a guarantee that this 10% requirement will always be met,
especially if a large number of corrections are transmitted.
