I don't remember any of those ELT ----- --------- or detected by satellite
Easily believable
I don't know what the xmon power is on the Judas collars we used on animals during the TB eradication by comaprison to your average ELT, but we had one very smart bovine who when she heard us used to gallop for cover and be hard to find. The freq we were using was around 150 megs.
We would be right up at 2,500 ft listening to the shlick - shlick in amongst very difficult static, constantly turning and tracking with a yargi aerial, hoping it woudl become a strong click - click, then it would fade, we would reciprocate or turn ninety degrees, but when the cow would detect us going away, she would head for other cover, we would hear a stronger signal briefly while she was travelling across open ground and so on. Finally we realised how much she was onto us and we relocated her collar onto another animal.
This was after only about four or five times tracking her to find her cohorts. One smart cow.
The cover was only isolated clumps of light timber up to about thirty feet but is was enough to completely block the signal at times from just a few mile away.
So, all the best there. tet
