Operating Guide

1. Band Selector: This switch allows you to switch bands, each band contains 40 channels, with each channel being on a different frequency.

2. Mon: The variable Mon control (talk back) is used to monitor your own voice.This can be used to compare different microphones. To increase the volume of the talk back rotate the control clockwise. To decrease rotate counterclockwise. To turn off the talkback rotate the control completely counterclockwise

3. Transmit Power or PWR – This variable control allows you to adjust your power output. Turn down when talking to nearby operators to avoid sounding distorted.

4. Mode: This switch controls what mode of operation the radio is in, option is AM, FM & PA.

5. Noise Blanker / ANL Switch: When this switch is in the NB position the noise Blanker circuits are activated. The Noise Blanker is very effective in eliminating repetitive pulse type noise usually associated with ignition systems. The NB+ position activates both the Noise Blanker and Automatic Noise Limiter (ANL) Circuitry.

6.Color: This switch controls the color of the front panel and display. To adjust the color move this switch to the left “COL” setting and then rotate the channel selector. Each click will select a color one option will be loop mode where the radio will automatically cycle through all of the colors.

7. Dimmer Switch: This switch controls the brightness of the front panel. To adjust the brightness move this switch to the left “DIM” setting and then rotate the channel selector clockwise for more light or counter-clockwise for less.

8. Channel Display: The channel display indicates the currently selected channel. When the SWR function is enabled, during TX, the display will show the current SWR such as 1.5.

9. Microphone Input: The Stryker SR447 accepts microphones with a female 4 pin connector. For maximum performance use the SR- 65BC noise canceling microphone. Please see our website for further details.

10. On/Off Volume Control: Turn clockwise to apply power to the unit and to set the desired listening level. During normal operation, the VOLUME control is used to adjust the output level obtained either at the transceiver speaker or the external speaker, if used.

11. Squelch: Squelch is used to cut off or eliminate receiver background noise in the absence of an incoming signal. For maximum receiver sensitivity, it is desired that the control is adjusted only to the point where the receiver background noise or ambient backgrounds noise is eliminated. Turn fully counterclockwise then slowly clockwise until the receiver noise disappears. Any signal to be received must now be slightly stronger than the average received noise.

12. Microphone Gain: Adjusts the microphone gain in the transmit and PA modes. This controls the gain to the extent that full talk power is available several inches away from the microphone.

13. RF Gain: This control is used to reduce the gain of the RF (receive) amplifier under strong signal conditions. For maximum receiver sensitivity, this control should be turned all the way to the right (clockwise).

14. Echo Volume: Varies the volume or number of echo repetitions. To increase the echo volume, rotate the control clockwise.

15. Echo Delay: The Echo switch turn the echo on. A big advantage to this is you can turn it off and then back on with the switch without the need to adjust your volume & delay potentiometer. To turn the echo off simply move the switch to the middle position.

16. Channel Selector: This control is used to select the desired transmit and receive channel. Please note the “LED” switch must be in the center position for this to function correctly.
