content: This would be fun: Build a low power transmitter and have people go out and try and find it. Put it in weird places like the woods; old buildings; all around town. Have a county or town that it broad casts to (maybe 1-5 watts? Higher watts with a stealth low gain ant.) at certain bands where it wouldn't cause interference and you could hunt around for it. Person that finds it could pick the next spot for it or modify it. Maybe make an Arduino beep morse in it and have a bunch of them all on the same frequency leading to more of a challenge. Do they already have TX's you can build? How much do those animal trackers cost that the park service uses? Set it up with solar or a big battery or stuff in apartment buildings and use the AC on the roof.

content: Quote from: ataradov on September 29, 2017, 05:42:36 amDid it get banned? I doubt it Foxhunting was banned in Britain (not the UK) a few years ago. I believe they come over here or to Northern Ireland, horses and all to participate.Edit to fix photo.

content: Used to be a regular thing in my old amateur radio club, many times I was the one to hide. You used to only transmit for around a minute every fifteen or so and play around with reflecting your signal off buildings and metals to confuse. We used the 2m band and triangulated with maps of the area. Later on people got more sophisticated with Doppler and Adcock DF systems.Have not done it for over twenty years though, so do not know current state.

content: Think they are talking about the one with the real fox being torn apart by dogs, with the poncy hats all sitting on the nags enjoying the "sport", as opposed to the searching for a small transmitter which is the Amateur radio foxhunt.

content: Quote from: Beamin on September 29, 2017, 06:07:47 pmI experienced a couple of unfortunate incidents with the authorities in southern California when hiding or hunting transmitters and that was before 9/11. One time they had the Secret Service in town at the Nixon Library for an event and we moved our regularly scheduled transmitter hunting event out of that area.After 9/11, I decided that hiding an ammo can or anything with an antenna attached was asking for trouble.
