What to do if my Kirisun Portable Radio receiving green light is on, but no voice is heard?
If the receiving green light is on but you hear no voice on your Kirisun Portable Radio, check these: * The speaker might be broken. * The audio power amplifier IC9 may be broken, so replace it. * The switch tube Q48 may be broken, so replace it. * The operational amplifier IC6 may be broken, so replace it.
Why does my Kirisun Portable Radio have no signal?
If your Kirisun Portable Radio shows no signal, here are a few things to check: * Make sure the antenna is well connected. * Low sensibility, trimming computer test mode. * The HF amplifier may be broken, so replace it. * The squelch level is too high, which makes the squelch unable to switch on, so reset it by PC. * The mixer tube Q19 may be broken, so replace the tube. * The Frequency Modulation IC4 may be broken, so replace the IC.
What to do if my Kirisun Portable Radio 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 Portable Radio, consider the following: * The power-amplifier tube may have no power output, so replace the tube. * The microphone might be broken. * The operational amplifier IC14 may be broken, so replace it.
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 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.
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.
Why Kirisun Two-Way Radio cannot transmit?
