What to do if no sound comes from the Icom IC-M710 Transceiver speaker?
- P

  If no sound is coming from the speaker, there could be several reasons. First, check if the [SPEAKER] switch is turned OFF and turn it ON. Ensure the microphone is connected to the [MICRO PHONE] connector. If the RF gain is set too deeply, push [FUNC], then [RX] to reset the RF gain (RF GAIN 9 applies audio). Finally, the squelch might be closed; adjust the squelch to the proper level or push [SQL] to turn it OFF to receive weak signals.

How to fix unclear or distorted transmit signal on my Icom IC-M710?
- S
  Scott WilliamsAug 23, 2025
  If your transmit signal is unclear or distorted, the wrong operation mode might be selected. Push [MODE] to select the proper operating mode. Also, ensure that the microphone is not too close to your mouth; speak into it naturally and avoid holding it too close.

What to do if the Icom Transceiver power does not come ON?
- N
  Nicholas ValentineAug 26, 2025
  If the power does not come ON when [POWER] is pushed, it could be due to a couple of reasons. Ensure the power cable is securely reconnected. Alternatively, a fuse might be blown; check for the cause, and then replace the fuse with a proper spare one.

Why is the received audio unclear or distorted on my Icom IC-M710 Transceiver?
- M
  michaeltateAug 27, 2025
  Unclear or distorted received audio can result from several factors. The wrong operating mode might be selected, so push [MODE] to select the proper operating mode. If AGC is deactivated while receiving a strong signal, push [AGC] to activate the AGC function. Also, if the noise blanker is turned ON when receiving a strong signal, push [NB] to turn it OFF. Finally, check the [CLARITY] control; adjust it to receive proper audio output if it's rotated too far clockwise or counterclockwise.

Why is the sensitivity too low on my Icom IC-M710 Transceiver?
- J
  James QuinnAug 30, 2025
  If the sensitivity is too low and only strong signals are audible, the antenna may not be properly matched to the operating frequency. Push [TUNE] to tune using the antenna tuner or select “automatic tuning” in the set mode when using an optional AT-130. Alternatively, the RF gain might be set too deeply; push [FUNC], then [RX] to reset the RF gain. Also, a wrong tuner condition might be selected in the set mode, so set the proper tuner for the connected tuner.

What to do if I cannot make contact with another station using Icom IC-M710 Transceiver?
- K
  Kim FernandezSep 1, 2025
  If no contact is possible with another station, the wrong transmit frequency might be set. Push [TX FREQ] to check and store the correct transmit frequency.

  If there is no sound coming from the speaker of your Icom Transceiver, check the following: * Ensure the [SPEAKER] switch is turned OFF. * Verify the microphone is connected to the [MICRO· PHONE] connector. * Reset the RF gain by pushing [FUNC], then [RX]. (RF GAIN 9 applies audio.) * Make sure the squelch is OFF by pushing the [SQL] switch.

Why does my Icom Transceiver signal not reach as far as usual and transmit signal is unclear or distorted?
- C
  Cory HicksSep 7, 2025
  If your Icom Transceiver signal doesn't reach as far as usual and the transmit signal is unclear or distorted, consider these potential causes: * The transmit power might be set too low. Reset it by pushing [FUNC], then [TX] to reset the transmit power. (RF-PWR 3 is maximum power.) * The antenna tuner might be improperly matched to the operating frequency when manual tuning is selected. Push [TUNE] to tune the connected antenna tuner or select "automatic tuning" using set mode. * CW or FSK mode might be selected for voice transmission. Select J3E mode (or H3E, R3E etc.) by pushing [MODE]. * The microphone may be too close to your mouth. Speak into it naturally, without holding it too close.
