Our club PHARC (Pune Hams and Amateur Radio Club) organised a Fox Hunt at DSK Vishwa, Dhayari, Pune. We earlier had couple of sessions of a workshop to build the famous Tape Yagi Antenna for this Fox Hunt. Though I skipped to build one, as many as 12 such Tape Antennas were built from scrap measurement tapes and were ready for the Fox Hunt.
A Fox (low power transmitter) was built by VU2ASH. This consisted a 16Mhz crystal working at 9th Harmonic that’s 144 Mhz and pulled a little up to work at precise frequency of 144.035. Further amplified with a 2N2222 based amp stage and some filtering added there after. Controlled by an Arduino Pro Mini. RF Power was about 40mW.
We were also joined by few team members of a local Ham club from Mumbai, Team MARI for this event. There were 3 separate Fox Hunts conducted one after the other with three winners for each of these hunts. Thanks to VU3MXE Devendra for lending me his Tape Antenna, I too made it to the winners list at the last Hunt 🙂
