Hi, I am looking for information to be able to put togeter a soft rock kit to receive 138KHZ, it is the frequency the RFIDs function at and I am having problems from EMI from various sources , If I could build a unit that could produce a spectrum analysis then I may be able to eliminate or discover what is causing my problem, Is there a unit that workis in this region or do I need to build an "up converter" and place infront of a conventional softrock?
Thanks in advance Ross
