Summary of Contents for Standard Horizon HX300

  • Page 1 Abstract This document describes the electrical characteristics of the programming in- terface utilized by the Standard Horizon HX300 floating handheld VHF radio. Two examples of programming interfaces are provided. The CE134 programming software will still be required for programming the radio.
  • Page 2 Disclaimer The sole purpose of this document is to provide owners of the Standard Horizon HX300 handheld VHF radio with information on how to make the most out of their units. While the Standard Horizon HX300 radio may come with relevant end-user documentation included, details regarding the programming interface are indeed sadly lacking.

    VHF ”user channels” as required. When adding ”user channels” to the radio, please take great care not to transmit on frequencies on which you are not licensed to operate. The official frequency ranges for the HX300 are listed as follows [9]: Transmit (TX): 156.025 to 157.425 MHz Receive (RX): 156.050 to 163.275 MHz...

    It should be noted that the communica- tion between the PC and the HX300 does not actually take place using standard USB communication. A direct connection between the PC and the radio, using an ordinary USB/mini-USB cable will only provide charging of the HX300.

    RT Systems, Inc., listed as the CT-62 [5]. The orig- inal Standard Horizon CT-172 cable assembly seems to be a bit harder to get hold of. Luckily, the original CT-172 is not really required for programming the HX300 radio.

  • Page 7: A Brief Examination Of The Hx300 Mini-Usb Connector

    Standard Horizon opted for a mini-USB connector both for charging and for program- ming the HX300 radio. The charging takes place using the Vcc and ground lines of the mini-USB connector. It is important to emphasize that programming the radio does not utilize normal USB data transfers and that a normal USB/mini-USB cable cannot be used to program the radio.

    2.2 Option 1: Using the USB-62B and the CT-99 cable assemblies For those who happen to have the Standard Horizon CT-99 cable assembly around, the remaining process will be fairly straightforward. The CT-99 is required for program- ming a number of fixed-mount Standard Horizon radios. It also happens to provide an easy means of hooking up to the USB-62B for accessing the TX DATA, RX DATA and GND lines.

    The green, white and black wires belong to the mini-USB connector which goes into the HX300. Refer to figures 4 and 5 for a review of the mini-USB pinout. 2.3 Option 2: Connecting to the FTDI Friend (and the likes) The FTDI [4] option is probably the least expensive route provided a USB-62B cable assembly (and/or a CT-99 cable assembly) is not already available.

    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].

    3.2 DIY programming software There is currently no known DIY programming software available for the HX300. The CHIRP project [2] may or may not support programming the HX300 in present or future releases. Readers who have in-depth knowledge of the programming protocol employed by Standard Horizon radios, including the HX300, are encouraged to forward these details to the author.
