How to troubleshoot abnormal frequency programming on Kirisun Radio?
To troubleshoot abnormal frequency programming on your Kirisun Radio: * **Wiring:** Check the wiring. * **USB Driver:** Check whether a USB driver is installed. * **Earphone Interface Board:** Check the contact of the earphone interface board. In case of poor contact, replace the USB socket.
What to do if communication fails on my Kirisun Radio?
If communication fails on your Kirisun Radio, consider these potential causes and solutions: * **Frequency Mismatch:** Ensure both radios are communicating on the same frequency. * **CTCSS/DCS Codes:** Verify that the radios are using the same CTCSS/DCS signaling codes. If not, set the same one via PC. * **Communication Range:** You may be out of communication range. Try moving within the specified range.
Why can't my Kirisun Radio receive signals?
If your Kirisun Radio is not receiving signals, here are a few things to check: * **Antenna Connection:** Make sure the antenna is securely screwed onto the connector. * **Squelch Level:** If the squelch is disabled due to a high level, set a lower level using a PC. * **Component Issues:** The LNA Q205, mixer Z201, or FM chip U201 may be broken and require replacement.
How to fix power-on issues with my Kirisun Radio?
If you're experiencing power-on issues with your Kirisun Radio, consider these potential causes: * **Low Battery:** The remaining battery capacity may be low. Charge or replace the battery. * **Broken Power Switch:** The power switch may be broken and need replacement. * **Internal Component Issues:** The power management chip U1 or Zener diode D1 could be broken and require replacement.
What to do if the red light is on during transmitting on my Kirisun Radio, but the receiver hears no voice?
If the red light is on during transmitting, but the receiver hears no voice, it could be due to: * **Power Amplifier Transistor:** The power amplifier transistor may not be outputting any power, requiring a replacement. * **Microphone Malfunction:** The microphone may not be working correctly, and you should replace it.
Why is the green light on during receiving on my Kirisun Radio, but I cannot hear any voice?
If the green light is on during receiving but you cannot hear any voice, consider the following: * **Speaker Issues:** The speaker may not be working well, so replace it with a new one. * **Audio Amplifier IC:** The audio amplifier IC5 may be malfunctioning, requiring replacement. * **Switch Diode Q9:** Replace the switch diode Q9.
What causes PLL failure in Kirisun Radio?
PLL failure in your Kirisun Radio can be caused by: * **PLL Crystal Oscillator:** If the PLL crystal oscillator U9 is broken, replace it. * **Oscillator Transistor:** If the oscillator transistor is broken, replace it. * **PLL Chip:** If the PLL chip U103 is broken, replace it.
