Added a gallery of pictures to my homepages: http://www.qsl.net/df3lp (Antenna, shack, etc.) Hope it works and will be of interest... 54°16'N / 10°04'E, JO54ag 73 es gl de Peter, DF3LP Hi Peter & LF-
Last night (27 april) arround 21UT I could hear OZ1KMR calling CQ with an incredible strong 589 signal. For comparision : this is about the same strength as PA0SE and PA0LQ who both are less than 150
Like all other LF-ham the message of Peter's death struck me with unbelieve as even in the last month you were in contact via e-mail and had the intention to make a sked for a CW QSO between DA0LF an
Due to limited time and very high QRN levels on saturday and sunday night only few stations were heard. Conditions on friday night were exeptional as despite the rather high QRN I could hear 2 Italia
I am sorry but i did not attach any file. The message was an ascii file typed in staight forward from the keyboard. If there are any problems reading the file, I can send it again. No problem to rea
Last night (sunday 9 may) I worked F6CNI on 136kHz (2-way !). This was my DXCC nr. 11, I am still 'missing' EI, OZ and SM. More detailled weekend report comes later today. 73, Rik Rik Strobbe ON7YD r
Again very little time to be active on LF this weekend. Spent most of saturday at the UBA annual meeting and sunday was 'motherday' here in Belgium so we visited my and my wife's parents. I could be
Due to the 'long weekend' of 13-16 may my weekend report covers this period. Lot of activity and despite heavy QRN often very good night condx. This weekend I noticed once more that I have very diffe
As a newcomer I hope I have right to ask silly questions. 1. How efficient is actually capacitancy hat of Marconi "T" ant? In other words, if there is space 40 meters horizontaly and 15 meters vertic
My local noise was off on Saturday and Sunday mornings so I was listening quite a lot on 136 and it seemed that conditions were bad. DF2PY was way down on his normal signal... were you running the no
But with the fancy new receivers now available (which I'll probably never be able to afford!), does the Group still feel 300 Hz to be a reasonable separation for normal CW operation? Over 10% of the
The book gives: Radiation resistance = 160 x pi squared x antenna height squared, all divided by wavelength squared (height and wavelength in same units). By multiplying this by the square of your an
I have also a question regarding the topic of radiation resistance of short verticals (with and without tophats) : All the formulas I saw so far alway assumed the vertical over a perfect ground. This
Pure mathematical the radiation resistance of a short (in wavelength) vertical monopole above a perfect ground is : Ra = 40 . Pi^2 . l^2 / L^2 ... The same vertical with a infinite top-capacitance ha
I forgot one thing to mention in my previous mail : a short vertical monopole above a perfect ground has a gain of 4.77dBi or 2.62dBd (due to the radiation pattern), so you have to add (multiply) thi
I am interested to find a reliable method to measure fieldstrength, I have read about some methods using small 1-turn loops but they all need good calibration. Regarding the distance : I read somewhe
Hi Alen, Thanks for the information, I think it is worth trying. If this method is correct I would de really easy to calibrate a loop for field-strength measurements. It strikes me that most usefull

One more weekend with very little time for LF as I attended the VERON National ARDF Competition on saturday and sunday. On friday evening I could hear G3YXM (579 despite strong QRN) in QSO with G3AQC
