uSDX88S 5波段手持短波电台
简介:这是一台短波手持收发器。便于携带到户外使用,支持CW自动解码。内置驻波功率计.使用gp88s电池(需要改为锂电池8.4v或者12.6v以保证功率输出)
特点:
5波段覆盖40m/30m/20m/15m/10m。
全模式支持:USB、LSB、CW、AM、FM(SSB模式接收效果好,发射效果差。AM和FM模式为赠送功能,效果差)
5波段输出功率达到5W功率,改12.6v电池可达到10w以上功率,并预留升级改造所需的SOT-223封装焊盘。
发射效率高,所有频段效率高于70%。
高精度KDS品牌TCXO,频率精度优于1PPM,频率稳定度优于0.5PPM。
LPF全部采用100V C0G/NP0电容。
使用磁保持继电器,更省电.
使用1602lcd屏,干扰更小
使用sma天线接口,方便转换bnc、m座等
整机带屏蔽罩,更低的本底噪音。
PCB厚度1.2注意,印刷电路板
