However to cut a long story short - I reckon my total resistance is about 30 ohms at the moment, may be a few ohms less, maybe a couple more. What doesnt lie Im hoping, is the thermocouple readings at one end and the HP6434 V/I meter at the other Changes include adding about amother 500pf to the top loading - pull and rearranging the load to be away from trees, adding more HV insulators, cutting down the odd tree overgrow, replacing the old variometer with a 8 gauge version, and finally using a autotransformer before the main coil, I think 3c90 core with 14T primary and 13T on towards the variometer, all with 1.5mm2 wires. Im still having issues with the W@G source on 275KHz - I need to buffer the +10 dBm 600ohm output a bit more as the sig gen is only just clocking the divider chip in the TX - if it doesnt clock properly all sorts of grief happens....
