Icom IC-202S Transceiver Specification

The Icom IC-202S is a portable SSB/CW transceiver designed for amateur radio operators, notable for its compact form and reliable performance in the VHF band. Operating on the 2-meter band, it offers a frequency range of 144 to 146 MHz, catering to both single-sideband (SSB) and continuous wave (CW) modes. The IC-202S is powered by a 9 to 13.8 V DC supply, ensuring versatility in power options for field operations or stationary use.

This transceiver stands out due to its robust build and lightweight design, weighing approximately 1.5 kg, making it ideal for portable operations and field activities. Its direct conversion receiver delivers clear audio with minimal distortion, while the transmitter offers an output power of approximately 3 watts, sufficient for a range of communication needs. The IC-202S features a VXO (variable crystal oscillator) for frequency control, providing stability and precision necessary for effective communication over long distances.

The front panel of the IC-202S is equipped with essential controls, including volume, RIT (Receiver Incremental Tuning), and a fine-tuning knob, allowing operators to easily manage audio levels and frequency adjustments. The transceiver also includes a built-in speaker and provisions for external accessories such as headphones and microphones, enhancing its usability in various environments. A signal meter on the display assists in monitoring signal strength and ensuring optimal transmission quality.

Overall, the Icom IC-202S is celebrated for its simplicity and efficiency, making it a favored choice for amateur radio enthusiasts who require a dependable and portable solution for VHF band communication.
