Optimized new version 2.0 of the kit for the EMC-SPY described by DJ3VY and DB1NV in FA 7/2012 for locating interference emissions.
Detecting sources of interference and testing the effectiveness of interference suppression measures is becoming increasingly important for radio amateurs and radio listeners today. A simple locating device such as an EMC-SPY can do a good job.
The built-in loudspeaker provides a quick acoustic overview of the interference situation and is automatically switched off when the headphones are connected. The increased AF bandwidth of the demodulated signal to about 10 kHz compared to the predecessor model improves the possibility of detecting pulse-shaped interferers. The four search antennas do not require any additional components. Their coils are designed as conductor tracks, which makes the probes mechanically less sensitive. In addition, the EMC-SPY can also be used as an AF signal tracker thanks to the adapter board supplied.
The new kit contains an SMD equipped board, all wired components, a machined and printed housing as well as four search antennas (probes) and an adapter board. The pre-assembled circuit board simplifies and accelerates the assembly considerably and makes it easy to handle even for less experienced hobbyists.
