The sea is about 400m south of my QTH I shut down the transmitter at 0100 and went to bed. Woke up at 0300 and couldn't get back to sleep. Checked the transmitter antenna current and it was 5amps! High tide was at 0250. E-mailed Dexter (John having shut down due to QRM) and he is now looking. Now transmitting, frequency 72.4005. Regards, Peter, G3LDO e-mail Web
