RX and comparing the Youloop clone

 


Less than one month after I have received the clone and left tit for the bet time to  test it. 

First notice about my other experiments with a home-made and the original received  from the rtl-sdr-blog in this link https://zachs-radiopage.blogspot.com/search/label/youloop

A short notice: I asked the seller to include two more sets of boxes but his messages shown rather unwilling to help me by no replying the  cost and possible additional shipping . I then immediately made the order after 4 days of waiting After receiving the parcel in 15 days i kept it in  a dedicated box for the Original antenna and left them for a later check. Finally this check has been made on the end of may!


Just a comparison between the boxes As you can see the black boxes are quite bigger than the originals but i also suspect that they are more stiffer and resistant in case other cables will be used. My idea is to replace all cables with TV and use longer reception cable to receive better the lower frequencies Even the  sockets are a bit  longer than the other's!


The tow antennas waiting for the test . as with the previous test . i preferred to keep them handing into a suitcase hanger. The clone's cable is possibly the same but it has a bad winding tat kept it quite irregular.The clone antenna used a 6 m cable  tested a few times for the report here but later it was left back to the common box



MY first time i used them together  hung into the door so i could test them with nearly no external signal. Instead of checking with their cables   separately I preferred toi use the original's cable for testing I already posted two videos in YouTube :

For unknown reason SDRC video recording stopped abruptly after 2-3 mouse rotations. Debut - paid option- was the only solution to grab video. It required  nearly half minute to stabilize the PC system after opened. Sometimes the CPU gets hot because of it.
