:GPSDO，GPS时钟，GPS钟，10M 10MHz 输出,比 原子钟 好；
才发现bg7tbl有成品开发哦。正好我的SDR有10M基准频率输入接口，有空搞一个试验一下。

前些时候和店主聊过 基本只能是用在其他地方了。
QS1R的10Mhz口是缺陷设计，
最好的办法是10Mhz驱动倍频至125Mhz插才能用
倍频方法如下
The QS1R as supplied uses a 125 MHz clock for the ADC (Analogue to Digital
Converter). The design actually allows for an external clock in the range
10-130 MHz (see QS1R FAQ page).
The principal supporting software assumes as sampling (clock) rate of 125 MHz,
so while you could use 10 MHz, EVEYTHING would be scaled wrong by 12.5:1 ,
and that includes any hardware filters.
To overcome this, you need a separate unit to generate 125 MHz from 10 MHz.
Such synthesiser units are quite common; most signal generators do it.
But there are PCB options. Here is one:
http://www.vk3hz.net/XRef/XRef_Home.html#XRef-Vx很可惜 只能靠ini文件调整偏差值 也许有哪位大大做个OCXO的GPSDO 125Mhz的
将来内置在里面挂顶，现状SMA调整为GPS
热切的希望 中国北斗星GPSDO的本版的出现 首先报名购买一块...!
