Antenna Safari - Sunday 23rd August - walking around Zinneke
types of antennas we came across :
- gsm antennas
- satellite dishes
- gsm repeaters (is that the correct term ?)
- radio amateurs' antennas ?
we listened to :
- noise in different locations that we could not decode
- elements of a conversation in French through a talkie walkie (hypothesis according to the range - maritime : two people on different boats)
- elements of a conversation (in English ?) through a laptop (hypothesis : conversations about airplanes)
- radio panic on a roof
- pager messages
