3.1 The CE134 PPS programming software

The Standard Horizon programming software for the HX300 is called CE134. It may or
may not be available from various online resources as the software is normally made
available to authorized Standard Horizon dealers only. There may or may not be differ-
ent versions of the software for the USA (possibly bandwidth limited) and non-USA
(not bandwidth limited) markets.
Several of the Standard Horizon radios available on the US market are known to be
bandwidth limited. It has not been established whether this also applies to the HX300.
The Wide Band Programming Recovery Tool may be able to allow extended bandwidth
operation also on the HX300. This utility is available from The Vertex Radio Group site
[8].
The original CE134 software will establish a handshake with the HX300 at 19,200
baud and continue the communication with the radio at 57,600 baud. The protocol
seems to be identical to the protocol used with the HX851 radio, briefly described in
[6].
In order to place the HX300 in programming/cloning mode, first switch the radio
off — then connect the USB cable and keep the PRESET key pressed in while switching
the radio on. The LCD display should indicate "CL" and move on to indicate "CP" once
communication has been established with the programming software.
