Icom IC-27E Transceiver Specification

The Icom IC-27E is a robust VHF FM transceiver known for its reliable performance in amateur radio communications. This device operates within a frequency range of 144 to 146 MHz, catering specifically to the 2-meter amateur band. It boasts a high RF output power of 10 watts, ensuring effective communication over considerable distances. The receiver sensitivity is rated at 0.18 µV for 12 dB SINAD, which facilitates clear reception even in challenging conditions.

The IC-27E features a 5 kHz channel step and a PLL synthesizer, providing precise frequency control and stability. This transceiver is equipped with 5 memory channels, allowing users to store frequently used frequencies for quick access. It includes a built-in CTCSS (Continuous Tone-Coded Squelch System) encoder and decoder, enhancing privacy and reducing interference by filtering out unwanted transmissions.

The user interface is designed for simplicity, featuring a large, easy-to-read LED display that shows the operating frequency and other pertinent information. The front panel includes a keypad for direct frequency entry, alongside various knobs and buttons to adjust volume, squelch, and other settings. An integrated speaker ensures clear audio output, while the external speaker jack provides flexibility for additional audio configurations.

The transceiver is housed in a durable case, suitable for both mobile and base station installations. Its power supply requirements are 13.8 V DC, typical for mobile transceivers, and it comes equipped with a detachable microphone for convenient operation. Overall, the Icom IC-27E is designed to deliver consistent performance with essential features for both novice and experienced amateur radio operators.

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

How do I perform a factory reset on the Icom IC-27E transceiver?

To perform a factory reset, turn off the IC-27E, press and hold the [FUNC] and [VFO/MR] buttons, then switch the power back on. This will reset the transceiver to its default settings.

What is the best way to clean and maintain the exterior of my IC-27E?

Use a soft, slightly damp cloth to wipe the exterior surfaces of the transceiver. Avoid using harsh chemicals or solvents as they can damage the finish. Regular dusting will help maintain its appearance.

How can I improve the signal reception on my IC-27E?

Improving signal reception can be achieved by using a high-quality external antenna, ensuring all connections are secure, and positioning the antenna as high and unobstructed as possible.

What should I do if my IC-27E is not powering on?

First, check if the power cable is properly connected and the power source is active. If the issue persists, inspect the fuse in the power cable for any damage and replace it if necessary.

How do I program frequencies into the memory channels on the IC-27E?

To program frequencies, switch to VFO mode, select the desired frequency, press [FUNC] followed by [MW], then choose the memory channel number and press [MW] again to store it.

What are some common troubleshooting steps for audio issues on the IC-27E?

Check the volume and squelch settings, ensure the microphone is securely connected, and test with an external speaker to rule out internal speaker problems.

How can I extend the lifespan of my IC-27E transceiver?

To extend the lifespan, operate the transceiver within recommended temperature ranges, avoid exposure to moisture, and perform regular cleaning and inspections for any wear or damage.

What is the procedure to adjust the squelch control on the IC-27E?

To adjust the squelch, turn the squelch knob counterclockwise until you hear noise, then slowly turn it clockwise just until the noise stops. This sets the squelch threshold correctly.

Is there a way to lock the controls on my IC-27E to prevent accidental changes?

Yes, press and hold the [LOCK] button until the lock indicator appears on the display. This will disable the buttons and knobs to prevent accidental operation.

How do I perform a firmware update on the IC-27E?

The IC-27E does not support firmware updates as it is an older model. Ensure you are familiar with all features and functions as per the user manual.
