Calibrate your two-way radios and verify continuous carrier signals instantly with the Jancore SF103 portable frequency counter.
You measure signals across 2MHz–200MHz and 27MHz–2800MHz while testing CTCSS/DCS codes on 144/430MHz bands and decoding DMR digital transmissions.
You navigate menus quickly with four control buttons and adjust the backlight on the 320 × 240 pixel TFT color display for any lighting condition.
You power your field tests with a built-in 3.7V 1500mAh battery that charges via micro USB and auto-shuts down after 1 to 9 minutes to conserve energy.
You capture stable readings thanks to 2–2.5ppm TCXO accuracy, 0.2-second response times, and a direct 50-ohm BNC input for precise impedance matching.
