How to fix phase locked loop unlocked on Kirisun PT6500?
If the phase locked loop is unlocked on your Kirisun Transceiver, it could be due to a broken Phase locked loop Crystal Oscillator X1, a broken oscillator tube, or a broken Phase locked loop IC2. In each of these cases, replace the broken component.
Why Kirisun Two-Way Radio cannot transmit?
If your Kirisun Two-Way Radio is unable to transmit, it might be because the frequencies of both users are not the same. To resolve this, select the same frequency channel again.
How to fix phase locked loop unlocked with “tick, tick” sound in Kirisun Two-Way Radio?
If you hear a “tick, tick” sound and the phase locked loop is unlocked on your Kirisun Two-Way Radio, the issue could be: * A broken Phase locked loop Crystal Oscillator X1: Replace it. * A broken oscillator tube: Replace it. * A broken Phase locked loop IC2: Replace the IC.
What to do if my Kirisun Portable Radio has no display after being switched on?
If your Kirisun Portable Radio's display doesn't turn on after you switch it on, the issue could be due to several reasons: * The battery power may be insufficient, so recharge or replace the battery pack. * The power switch may be broken, consider replacing it. * The CPU may be broken, consider replacing the IC. * The regulator tube Q45 may be broken, consider replacing the IC.
Why can't my Kirisun Portable Radio transmit?
Your Kirisun Portable Radio might not be able to transmit due to a few reasons: * The frequencies of both users are not the same. To resolve this, select the same frequency channel again. * The CTCSS/DCS signaling of both users are not the same. To fix this, set it with PC. * You might be beyond the efficient communication range.
What to do if Kirisun PT6500 transmitting red light is on, but no voice is heard?
If the transmitting red light is on but no voice is heard on your Kirisun Transceiver, the issue could be due to a power-amplifier tube with no power output, which would need replacement. Another possibility is a broken microphone, which should also be replaced. Finally, the Operational Amplifier IC14 may be broken and also require replacement.
Why does my Kirisun PT6500 Transceiver have no display after being switched on?
If your Kirisun Transceiver's display remains blank after you switch it on, the issue might stem from several causes. It could be due to insufficient battery power, in which case you should recharge or replace the battery pack. Alternatively, the power switch itself may be broken and need replacement. Other potential causes include a broken CPU or a broken Regulator tube Q45; in both cases, replace the IC.
What to do if my Kirisun PT6500 Transceiver cannot transmit?
If your Kirisun Transceiver is unable to transmit, consider these possible causes: ensure that the frequencies used by both transceivers are the same by selecting the same frequency channel. Also, verify that the CTCSS/DCS signaling settings are identical for both users, configuring them via PC. Finally, check if you are within the efficient communication range.
What to do if Kirisun Portable Radio has no signal?
If your Kirisun Portable Radio shows no signal, ensure the antenna is well connected. Low sensibility can also cause this issue, try trimming in 'computer test mode'. Other potential causes include a broken HF amplifier (replace it), a squelch level that is too high (reset it by PC), a broken Mixer tube Q19 (replace the tube), or a broken Frequency Modulation IC4 (replace the IC).
What causes abnormal programming in Kirisun Portable Radio?
If you are experiencing abnormal programming with your Kirisun Portable Radio, consider the following: * Make sure the wires are well connected. * There may be abnormal output of the RS-232 serial port of the computer, so check the computer. * There may be an abnormal connection of MIC and SPK jack, so check the jack.
