Precision 19.6651 MHz Crystal Oscillator for Icom Radio Frequency Generation
This is a genuine Icom crystal oscillator marked "19651" (indicating 19.6651 MHz frequency) used in various Icom two-way radio models. The component features a metal can housing with the frequency marking clearly visible on top, mounted on a black plastic base with surface-mount solder pads. The underside shows a circled "4" manufacturer marking. Crystal oscillators are precision frequency reference components that generate the stable clock signals required for accurate radio frequency synthesis, ensuring the transceiver transmits and receives on the correct frequencies within tight FCC tolerance specifications.

Application & Installation
This crystal oscillator is a precision frequency reference component that requires professional installation by a qualified radio technician with surface-mount soldering capabilities. The crystal provides the stable reference frequency used by the radio's frequency synthesizer to generate all transmit and receive frequencies. Replacement is necessary when the crystal fails due to physical shock, thermal stress, age-related drift, or electrical damage, resulting in symptoms such as inability to transmit or receive, frequency drift outside FCC tolerance, erratic frequency behavior, or complete radio failure. Installation requires precision surface-mount soldering with proper temperature control to avoid thermal damage to the crystal element inside the metal can. The component must be oriented correctly and soldered with clean connections to both pads. After installation, the radio requires comprehensive frequency alignment using specialized RF test equipment including frequency counters accurate to at least 1 Hz resolution, spectrum analyzers, and deviation meters to verify the radio operates on correct frequencies within FCC specifications. This is a critical frequency-determining component, and improper installation or lack of post-installation alignment will result in radios that operate off-frequency, violating FCC regulations and preventing proper communication with other radios. This repair should only be performed by technicians with appropriate skills, tools, and access to Icom service documentation.
