Covering a wide 10 kHz to 220 MHz range, it serves as a precise local oscillator for superheterodyne receivers, software-defined radios, DCR transceivers, and Ham QRP stations. With a 0.5 PPM TCXO clock, selectable tuning steps (1 Hz, 10 Hz, 1 kHz, 5 kHz, 10 kHz, 1 MHz), and adjustable IF offset, this module makes dialing in frequencies accurate and effortless. It features 20 band presets for quick access to common BCB and HAM frequencies, a dedicated generator function mode, and an RX\/TX selector for homebrew rigs. The bar-graph signal meter (via ADC) provides at-a-glance signal strength, while the device can function as an RF\/clock generator or as a local oscillator for your own receivers. It can interface with a common 128x64 I2C OLED SSD1306 display and the Si5351 module, using only two I2C lines for data transmission. Compact, battery-powered, and ready for your next project, this transceiver is an excellent choice for hobbyists and builders.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cb\u003e2–in–1 flexibility:\u003c\/b\u003e Use it as a precise VFO for superheterodyne receivers, or as an RF\/clock generator for calibration and reference tasks.\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eRapid frequency access:\u003c\/b\u003e 20 band presets help you jump to favorite bands and HAM frequencies in seconds.\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eEasy I2C integration:\u003c\/b\u003e Connect to a 128x64 OLED SSD1306 display and the Si5351 module with just two I2C lines for a clean, compact setup.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cb\u003eName:\u003c\/b\u003e Transceivers\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eBrand:\u003c\/b\u003e KKMOON\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eOrigin:\u003c\/b\u003e Mainland China\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eCertification:\u003c\/b\u003e CE\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eDisplay Size:\u003c\/b\u003e 2.9 Inches \u0026amp; Under\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eWorking Range:\u003c\/b\u003e 10 kHz to 220 MHz\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eTuning Steps:\u003c\/b\u003e 1 Hz, 10 Hz, 1 kHz, 5 kHz, 10 kHz, 1 MHz\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eFrequency Stability:\u003c\/b\u003e 0.5 PPM TCXO clock\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eSpecial Features:\u003c\/b\u003e 20 band presets, generator function mode, RX\/TX mode selector, S-Meter bar graph, I2C interface with SSD1306 and Si5351\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eBattery:\u003c\/b\u003e 1 × 3.7V, 600 mAh battery (included)\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eItem Size:\u003c\/b\u003e 90 × 100 × 40 mm\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eItem Weight:\u003c\/b\u003e 200 g\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003ePackage Size:\u003c\/b\u003e 175 × 126 × 55 mm\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003ePackage Weight:\u003c\/b\u003e 256 g\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e1 × Transceivers\u003c\/li\u003e \u003cli\u003e1 × Type-C Cable\u003c\/li\u003e \u003cli\u003e1 × 3.7V, 600mAh battery (included)\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWarnings \/ Reminders\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eThis is a DIY VFO project intended for electronics hobbyists.
