Icom IC-27H Transceiver F.A.Q.

How do I perform a factory reset on my Icom IC-27H Transceiver?

To perform a factory reset on the Icom IC-27H, turn off the radio, then hold down the 'FUNC' and 'VFO' buttons while turning the power back on. This will reset the settings to factory defaults.

What is the best way to improve transmission range on the IC-27H?

Improving transmission range can be achieved by ensuring your antenna is properly tuned and elevated, using a higher quality coaxial cable, and ensuring the transceiver is operating at full power.

How can I troubleshoot audio distortion issues on my IC-27H?

Check the microphone for damage or loose connections. Additionally, ensure the squelch and volume settings are adjusted correctly, and that there is no external interference.

Does the IC-27H support dual band operation?

No, the Icom IC-27H is a single band transceiver that operates on the 2-meter VHF band.

What maintenance checks should I routinely perform on the IC-27H?

Routinely check the antenna connections, clean the transceiver exterior, inspect cables for wear, and ensure the cooling system is dust-free to prevent overheating.

How can I program frequencies into the IC-27H?

To program frequencies, switch to VFO mode, select the desired frequency using the tuning knob, and store it in memory by pressing 'FUNC' followed by the desired memory channel button.

Why does my IC-27H keep losing programmed channels?

This may be due to a failing internal battery that retains memory settings. Replacing the battery should resolve this issue.

Can I use the IC-27H with a power amplifier?

Yes, the IC-27H can be used with a power amplifier. Ensure the amplifier is compatible with the VHF band and that connections are secure to avoid damage.

What should I do if the display on my IC-27H is not working?

First, check the power supply and connections. If the issue persists, it may be necessary to inspect the internal connections or consult a professional technician for repair.

How can I adjust the squelch setting on the IC-27H?

To adjust the squelch, locate the squelch control knob on the front panel and rotate it until unwanted background noise is muted while ensuring the desired signals are still audible.
