Why can't I hear the speech after pushing SPEECH on my Icom Transceiver?
If you cannot hear the speech after pushing SPEECH on your Icom Transceiver, the speech level may be too low. Adjust the speech level in the Speech setting.
How to save changes to a memory channel on Icom IC-7300 Transceiver?
If the contents of a selected memory channel are not changed on your Icom Transceiver, touch [MW] for 1 second to write them into the memory channel in the VFO/MEMORY screen when you want to save the changed settings.
What to do if MAIN DIAL is not changing frequency on my Icom Transceiver?
If the displayed frequency on your Icom Transceiver does not change properly when rotating the MAIN DIAL, the Dial Lock function may be activated. Hold down the SPEECH button to turn the Dial Lock function OFF.
How to fix no sound from the speaker on my Icom IC-7300 Transceiver?
If you're not hearing any sound from the speaker of your Icom Transceiver, here's what to check: * Rotate AF RF/SQL (inner) clockwise to increase the audio level. * Rotate AF RF/SQL (outer) to the 12 o’clock position to open the squelch. * Turn OFF the Tone squelch if it's ON in the FM mode. * Disconnect any headphones or external speakers connected to the [PHONES] jack. * Inspect the external speaker cable for cuts and repair if necessary.
How do I fix an Icom Transceiver touch screen that isn't working correctly?
If the touch screen on your Icom Transceiver is not working correctly, the touched point and the detected point may be different. Calibrate the touch screen.
Why is the received audio unclear in SSB mode on my Icom Transceiver?
If the received audio in SSB mode is unclear or distorted on your Icom Transceiver, the incorrect sideband may be selected. Try toggling between USB and LSB. It's also possible that the PBT function is activated; hold down TWIN PBT CLR to clear the settings.
Why can't I contact another station with my Icom Transceiver?
If you cannot contact another station with your Icom Transceiver, even though receiving and transmitting appear successful, the Split function may be activated, causing transmit and receive frequencies to differ. Push the SPLIT button to turn OFF this function. Alternatively, the RIT function or the ?TX function might be ON, also setting different receive or transmit frequencies; push RIT or TX to turn OFF these functions.
What causes a high antenna SWR on an Icom Transceiver?
If the antenna SWR is too high on your Icom Transceiver, it could be that the antenna is not properly tuned. Adjust the antenna SWR to be less than 3. Also, ensure you are using a coaxial cable with a characteristic impedance of 50 Ω.
What to do if my Icom Transceiver displays “OVF”?
If your Icom Transceiver displays “OVF,” it means an excessively strong signal is being received. Try rotating the AF RF/SQL (outer) dial counter-clockwise. If this doesn't help, turn ON the attenuator.
Why is the received audio unclear on my Icom IC-7300 Transceiver in SSB mode?
If the received audio in SSB mode is unclear or distorted on your Icom Transceiver: * Toggle between USB and LSB to select the correct sideband. * Hold down TWIN PBT CLR to clear the settings if the PBT function is activated.
