Content preview: LF, I want to keep those who are interested in the progress of the Venezuela Grabber informed. Since a few days, a resonated circuit on a ferrite rod is used to match the antenna to the IC703. It looks like there is an S/N improvement of DCF39 reception of about 10 dB!

This is how the DCF plot of the last night looks: http://dl.dropbox.com/u/19882028/LF/LFplot.jpg From the diurnal variation of the background noise it looks to me as if there is at least room for another 6 dB improvement, i.e. the RX noise is still dominant. Very soon, a wideband LF converter is used. All in all it looks most promising to me that there will be chances to leave a trace then in YV even in summer. http://dl.dropbox.com/u/74746618/LF/YV7MAE_LF_Grabber.html 73, Stefan/DK7FC
