I purchased this kit about a year ago, time to write a review. First, the kit is 13 dollars so don't compare it to a 200 dollar unit. This kit was very easy to build, I use it for QRP and SDR.
The amplification from this unit, while on my receivers for QRP, is highly noticeable, it does a fine job of increasing the signal. Using my SoftRock Lite with WINRAD, I can have displayed on my computer a waterfall with one or two signals, turn on the Ten-Tec Amp an 10 more or what ever is active is displayed on the waterfall. I was surprised, a 13 dollar unit does so well.
It is worth the price, even it it was 25 dollars it would be worth it. Again, I was surprised how well it worked. If you have a SDR receiver, buy this, you won't be disappointed, you will see the results in the waterfall.

I did not fully understand which was pin #3. The chip had a white dot but also had a "1" - so guess what - I think installed it backwards. I have ordered another chip on Amazon - hope to have better luck next time.
