What to do if Kirisun PT8100 -01 Radio has abnormal programming?
If you are experiencing abnormal programming with your Kirisun Radio, consider the following: * Check the programming cable connection to ensure it is properly connected. * Verify the RS-232 serial port output of your computer. * Inspect the radio’s socket for the programming cable for any contact issues. If the socket is faulty, replace it.
How to fix Kirisun Radio power on failure?
If your Kirisun Radio fails to power on, there are several potential causes: 1. The power cable might not be properly connected. Reconnect it, ensuring the power voltage is greater than 13V. 2. The power cable's fuse could be burnt out, so replace it. 3. The power button may have poor contact; in this case, replace the rubber key or the key PCB. 4. The battery might be depleted. Try charging it or using a new one. 5. The MCU could be broken, requiring replacement of the IC. 6. The zener diode IC17 may be faulty; replace the IC.
What to do if Kirisun PT8100 -01 Radio has no signal?
If your Kirisun Radio shows no signal, it could be due to several reasons: * The antenna may not be securely connected. Ensure it is fastened tightly. * The sensitivity might be set too low. Adjust it in the “Tuning Mode”. * The high-frequency amplifying tube Q18 could be broken, requiring replacement. * The squelch level might be too high, preventing it from opening. Reset the squelch level. * The mixing tube Q19 could be damaged and need replacement. * The FM processing chip IC16 may be broken, requiring replacement.
Why is my Kirisun PT8100 -01 beeping and showing PLL unlocked?
If you hear a beeping sound and your Kirisun Radio displays 'PLL unlocked', it might be due to: * A broken PLL crystal oscillator X1, which needs to be replaced. * A faulty oscillator transistor, which also needs replacement. * A broken PLL IC3, requiring replacement.
What to do if transmitting red light is on, but no voice is heard on Kirisun PT8100 -01 Radio?
If the transmitting red light is on but the recipient doesn't hear any voice from your Kirisun Radio, it could be due to: * A broken power module IC1, which prevents power output and needs replacement. * A faulty microphone, which should be replaced. * A broken operational amplifier IC13, requiring replacement.
Why is there no voice on my Kirisun PT8100 -01 Radio when the receiving green light is on?
If the receiving green light is on but you hear no voice from your Kirisun Radio, check the following: * The speaker might be broken, and you should replace it. * The audio power amplifier IC7 could be faulty; replace it with a new IC. * The switching tube Q33 might be broken; replace it with a new one. * The operational amplifier IC9 may be broken; replace it with a new IC.
