Hi Gary you will just get more volts out of it at higher curent......if that drives the meter off-scale reduce the number of secondary turns, or use a potential divider to reduce the voltage. RF Ther
Dear Gary, LF-Group, The coupling between the primary and secundary winding of the current transformer must be purely inductive. But even with a one-turn primary there is also capacitive coupling. Es
Dear Gary, LF Group, The RF ammeter circuit in the LF handbook and on K0LR's web page uses a current transformer to develop a voltage of a few volts across a load resistor when the appropriate RF cur
Dear Gary, LF Group "When I have looked at designs in amateur radio magazines or internet for a clip on RF Ammeter the designs seem to be limited to 2 ranges (100mA & 1A FSD), is there a limit to the
