All I will say with regards to the ADCR25 board from Russia is use caution in dealing with this guy. I sent a PayPal payment to him on 02/27/2015; heard nothing for several weeks and then after repeated correspondences back and forth, I finally opened up a PayPal dispute. He insisted that he mail the item to me, even provided a Russia Post Office tracking number, which couldn't be tracked here in the U.S. up-to and including after the resolution from PayPal on the issue. The PayPal resolution issue drug on into May, where he kept saying he could not issue a refund; finally, after escalating the issue, a PayPal refund was issued. Then a few days later, he e-mails me and says he gave me the incorrect tracking number for an items that was mailed in March; here we are in May and all of a sudden the new tracking number shows it's in New York. The long and the short of it is, the board eventually arrived in May; however, it was broken in two pieces. It was only packed on an envelop, like it was thrown in the mail last minute. After dragging on since the end of February, he honestly wanted me to pay postage back to Russia and wait for a replacement after already waiting several months and having to go through the whole process I did; I don't think so. I asked him for a return postage paid return; I have yet to receive anything. Having received my refund through PayPal, I threw the broken board in the trash and moved on. Now he's threatening me online and essentially calling me the thief. Those who know my online reputation know what to expect from me, so I could careless at this point; this guys a total nut job and his posting my full name, address, call sign, etc on his website and in his users manual just goes to show how unprofessional he really is. If anyone would like to see a list of my corresponsdances with this guys, please let me know and I'll be happy to share them and the details of the PayPal dispute.
My suggestion is to stay away from the ADCR25 and purchase an AirSpy and use DSD, this combination will do exactly the same thing and covers all bands. A friend suggested this ADCR25 board and that's why I initially jumped on it; however, following this experience, I will NEVER purchase anything from outside the U.S. again...
