Here is a diode mixer at work.

RF signal is 1mv @ 1MHz; LO is 1v @ 10.465Mhz. The IF signal generated is about -80db @ 465Khz, just as expected.

Thanks， man!

I called a dealer for a quote of ADE-1+ , they said 15 RMB each. that's expensive!!

Do you know of any house-hold device that comes with a mixer like ADE-1+ ?

VCR ? 900MHZ/2.4GHZ cordless phone? Motorola Cable modem (Surfborad 51xx) ?

That's not a bad price. But making one is definitely more fun.

Allow me. I searched ADE-1 on www.taobao.com and found that there are many parts named after ADE-1-24. It only costs 6 RMB each. Is there any difference between ADE-1 and ADE-1-24?

看起来是起止频率的区别。

本以为国内会便宜一些。

ADE-1L+ 厂家 20 个报价 4 刀一个。

Looks like you can use the dongle + upconverter to receive digital shortwave broadcast (DRM).

这个混频器的IP3指标怎样啊？

这个东西在频率应用不是灰常高的时候完全可以自制

Supposedly QST 1/13 issue talked about using an upconverter to allow the dongle to listen to broadcase signal.

So this topic is "international frontier",

Some of. The sticks can only tune 60Mhz and up. Others (mostly newer sticks) can tune 25Mhz or up. So a 50Mhz LO will not work for the former.

Also if you are into direct soldering, a wire to 2832's pin 1/2 and change of a sampling source in sdrsharp (to direct sampling) is all it takes to tune to the 0-22Mhz band.
