From time to time we’ll be bringing back photos of past events and featuring articles from past RHG issues.
To start the series off here’s a few photos of a fox hunt to track down a jamming transmitter located in downtown Chicago. The transmitter was found at the top of the Hancock building. These photos were taken in either 1997 or 1998 around Christmas as evidenced by the star hanging between the two antenna masts in one of the photos.
