Hi all

I have been looking for a high voltage tester. The idea is to use it to measure voltage at the MF coil

and also playing with transformers for VLF Tx as Stefan explained few days ago

I found professional stuff and also cheap electric fence testers. Some models based on neons and others

even digital and up to 10kV. For example this one

http://www.ebay.es/itm/Digital-Electric-Fence-Tester-High-voltage-Tester-300-9900V-Handheld-US-Ship-/252161204946?hash=item3ab5faa2d2:g:e7oAAOSwIgNXrTq7

Would it work for our purpose at MF frequencies ?
