Subject: CMX882 Pseudo Code Implementation

The CMX882 is a sophisticated modem + baseband processor targeted at “family radio” applications (e.g. FRS/GMRS/MURS/PMR446 radios).
It is particularly well suited to family radios that include facilities for text messaging and GPS location data exchange.
The purpose of this application note is to illustrate how the CMX882 can be configured for a feature-rich “family radio” product.

Subject: HSC and XTCSS Coding for Radio and Paging Systems

The Hexadecimal Sequential Code (HSC) is a coding format for sequential tone signalling systems. HSC permits address codes, instruction codes and data blocks to be exchanged on an unrestricted basis between all units in a network, thus providing the key to the design of fully integrated base/mobile/personal communications schemes.
HSC is also compatible with the frequencies and protocols used for international '5-tone' selective call (SelCall).
