Page 6: Introduction
Under software control, the centre-frequency can be arbitrarily tuned across a band, within the limits of the installed receiver and transmitter submodules. A range of available submodules allows The Eclipse2 system to cover most of the band from 66MHz to 941MHz. -

Full EIA CTCSS capability as well as nonstandard sub tones are built into the modules. The CTCSS tone can be programmed for each channel in their profiles. This means each channel can represent a unique TX/RX and tone frequency combination. Eclipse2 Technical Manual, 3-Aug-12 Page 15 of 17... -
Page 16: Channel Programming
Channel Programming The channel information is stored in Flash memory and can be programmed via the Ethernet, USB or RS232 interface using a Host PC and RF Technology’s Service Kit software. Channel Selection Channel can be select by Service Kit or front panel buttons (if enabled). - Page 17 This separation distance also does not take into account any other transmitters that might be considered co-located at the same site. An RF exposure report was prepared for this transmitter and in it are the typical calculations on which the above is based. Eclipse2 Technical Manual, 3-Aug-12 Page 17 of 17...
