  • Page 1 LIMITED WARRANTY Stryker Amateur Radio warrants this product to be free of defects for a period of one (1) year from the original date of purchase. This warranty is non-transferable. This limited warranty is subject to repair or replacement of defective components only. This warranty is void if the radio has been tampered with or misused.

  • Page 2: Installation

    Electrical Connections The Stryker SR440-HP is designed to work on any 13.8 volt DC, negative ground electrical source. The condition of a vehicle’s electrical system can have a profound affect on the performance of the radio. A low battery, worn generator/alternator, or poor voltage regulator will seriously impair the performance of the transceiver.

  • Page 3: Antenna Connections

    Antenna Connections The Stryker SR440-HP has a jack in the rear for a standard PL-259 antenna plug. If you are looking for the most range for your transmission, use a vertically polarized, quarter-wave length antenna. If antenna height is a problem, you may use a shorter, loaded-type whip antenna although you can expect some loss of transmission range.

  • Page 4: External Speaker

    Tuning the Antenna for Optimum SWR CONTINUATION 3. The whip is easily cut by filing a notch all the way around, then breaking the piece off with pliers. NOTE The proper setting is achieved when the SWR is 1.5 or below and when it has the same reading for the low and high frequencies in the range you plan to use.

  • Page 8: Alternate Microphones And Installation

    ALTERNATE MICROPHONES AND INSTALLATION For best results, the user should select a low-impedance dynamic type microphone or a transistorized microphone. Transistorized type microphones have low output impedance characteristics. The microphones must be provided with a four-lead cable. The audio conductor and its shielded lead comprise two of the leads. The third lead is for transmit control and fourth is for receiving control.
  • Page 9 Before beginning the actual wiring, read carefully the circuit and wiring information provided with the microphone you select. Use the minimum heat required in soldering the connections. Keep the exposed wire lengths to a minimum to avoid shorting when the microphone plug is reassembled. To wire the microphone cable to the plug provided, proceed as follows: 1.
