DP666 is a highsensitivity radio based on NXP's highperformance automotivegrade TEF6686 chip, which has excellent selectivity and ultrahigh sensitivity. This automotive DSP tuner has a wide range of functions and advanced algorithms (CEQ, EMS, iMS and PACS, noise canceller...), SDR(softwaredefined radio) signal processing, especially for improvement of multipath, adjacent frequency interference, weak signals There are significant advantages in processing and noise cancellation.DP666 is a radio built on PE5PVB's open source project TEF6686_ESP32. In addition to listening to radio stations, the project also supports a wealth of advanced features, such as: almost all RDS (Radio Data System) data display, automatic/manual station scanning, squelch function, battery voltage display, changeable themes, multilingual, station presets, and more.We redesigned the circuit board with reference to the mature TEF6686 frontend receiving circuit, and equipped the DP666 with a 2.8inch LCD color screen with resistive touch based on the open source project. While ensuring the portability of the machine, it can display rich RDS information (RDS information requires local radio support); a numeric keypad is added to facilitate users to quickly input frequencies; and a largecapacity 5000mAH battery supports longer standby time.In short, I hope you will be satisfied with this portable highsensitivity travel radio!Colour:YellowMaterial:plastic+metalPackage Contents:1 * RadioOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
