Although antennacurrent is higher now, my signal did not seemed to be stronger........... Alan told me already in an mail that grounds can be tricky on LF........ Meanwhile TX/RX system is ready, as well as an bigger 50Ohm to 135 Ohm transformer. I hope to finish a bigger current meter tomorrow, completing the station. That means that I might be QRV from then. There is however one problem........... My parents where the TX-site is, have some visitors during Easter, and one from them has MS, ans is very sensitive for LF electromagnetic fields........ And indeed, he had some pain in his head when running the test TX this afternoon. He could even notice the CW-keying...... Another uncertainty is the weather.........no idea what rain does with the isolation in the system (flash-overs or what ever) Anyway, I will try to be on tomorrow, and hope to work some stations in CW around the usual 136.6kHz (my test TX is X-tal controlled on 136.15kHz, my high power TX has VFO) 73 Dick, PA4VHF
