Hello LF'ers, My scopemeter shows current and voltage waveforms of course, but what relationship does the current waveform have to the actual antenna current? I am sad to say I haven't yet built a tr
Hi Chris, The waveform should look like a pure sine wave. Then it would say nothing but "it's all right, pse QRO!". Maybe i misunderstand the question. BTW you are QRV in WSPR. Are you also ready for
Well it depends on what you mean by scopemeter ... Do you mean a scope match <http://ve7sl.blogspot.co.uk/2014/08/your-lf-stations-best-friend-scopematch_5.html> ? or one of those 'fluke' handheld s
Hello Nick, Sorry, for some reason I always call it a scopeMETER wheras I really mean a Scopematch, and I too have built it to give equal height traces. the traces are perfect sine waves and near as
Hello DK7FC, Hi Stefan, I replied in depth as to what I really mean above. I mix Scope meter and scopematch up sometimes ;) I have never tried JT9, and am not sure if my U3S exciter runs that mode. H
Hi Chris, Have a look at this page on my website. At the bottom right is a link which may answer your question. http://myweb.tiscali.co.uk/wgtaylor/LF%20&%20MF%20Experiments%2013.html A very informat
Ah! Now there is a question - to which I don't know the answer. Too many variables I think. When I did put a gash RF-current meter in line with my antenna it mucked up the tuning, quite a lot :-( So
Hello DK7FC, I have never tried JT9, but it appears my U3S exciter covers that mode. What time span (there's JT9-2 upwards it seems), and what frequency is appropriate? I am happy to give it a shot!
