The other key component of the SmarTrunk II system is a miniature
logic board which installs inside the mobile or portable radio equip-
ment. These logic boards are custom designed for each radio and
control all the signaling and trunking functions, including scan, PTT,
and monitor. In most cases, the logic boards are easily installed by
plugging into the host radio; however, soldering may be required in
some older radios (See SmarTrunk II Logic Board Collection, Appen-
dix A).
Highlights of the Omni feature set includes Channel Banks for multi-
site applications, multiple talk and receive groups, faster channel
access, positive radio kill, and greater use of the radio’s display.
The Omni feature set is currently available for radio models from Icom,
Kenwood, Motorola, Standard, and Yaesu/Vertex (see Appendix A for
details). A summary of the Omni features is listed below:
Channel Banks
The Channel Banks feature allows
subscribers to access different sites which
may use different frequencies. Channel
Banks are accessed via the radio’s Channel
select switch i.e. Channel 1 would become
Frequency Bank 1.
By programming the frequencies of different
SmarTrunk II or conventional sites as
Channel Banks on the subscriber radio, system operators may offer access
to multiple sites or even allow the radio to operate in conventional Talk-
Around mode. To access a remote site, the subscriber selects the Channel
Bank of the desired site. The diagram shown on the left explains a typical
Channel Banks application.
