Many thanks to those who sent signal level and frequency reports and pictures. Got the 73kHz transmitter fired up at around 2130UTC after the loading coil problems had been fixed. The main limitation to beaconing is the power supply. My PSU comprises a 70V home made unit, which gives a maximum of 10amps. This supply is stiffened with a bank of UPS computer batteries. This works fine for limited sessions on full power or long sessions at reduced power. It was fine for the T/A 136kHz QSO that only lasted 55mins. For this reason I shut the transmitter down at 0100 last night. I will have to get into propagation studies! Regards, Peter, G3LDO e-mail Web
