Thank you all for your reports and the pictures enclosed. Today was very windy as usual, it was even a storm and so maybe not the best weather to do some tests. At least it was (almost) dry. I had to interrupt two times due to light rain. The loading coil (460 to 570mH Variometer)is on a 400 litres barrel, located in "open air". If it gets wet, the enamel-insulation may blow and I don't want to take that risk. I'm using an Audio-PA to generate about 150W (?) output at 14V and 14A input. I don't have any idea about the efficiency of Audio equipment so this is only a guess. The antenna is my LF-Marconi: 16m vertical and abt. 100m topload at least 12m above ground, all realised with fibre-poles. That's why this construction is very sensitive to strong wind. The antenna-current was measured at 500mA with a full-bridge rectifier and a 1R shunt-resistor, normalized to RMS. I think by end of this month I will have a GPS-disciplined generator available which will produce much nicer pictures on grabbers than I do now. Many thanks for your reports and efforts and 73 OE3GHB Gerhard Am Samstag, den 15.01.2011, 15:51 +0100 schrieb Jacek Lipkowski: > On Sat, 15 Jan 2011, Gerhard Hickl wrote: > > > I will have my TX running on 8969.97 (+/- 0.03) today. > > > > Locator is JN88hl, power to the antenna is abt. 150W > > you're also visible in 3.8mHz bandwidth. well done Gerhard! > > what is the antenna, and what antenna current? > > VY 73 > > Jacek / SQ5BPF
