Dear all, around 23.45 UTC on September 7th I had audible copy of SK6RUD on 500 kHz in eastern Bavaria. But QRN and QSB is still rather high and I still miss many letters when trying to copy the beac

Dear all, until this night (November 18 to 19) I have had problems to hear GI4DPE at all for several weeks in eastern Bavaria, in spite of seeing him on the Shetland grabber and that he could be copi
Dear Peter, I am using a home brew antenna bridge in which variable R and C are in parallel. This bridge is about 20 years old, and one reason for this parallel arrangement has been that at the time
Dear all, especially DL's, on december 26th around 15.30 UTC I have worked DK1KH nr Munich for the first time on LF over a 100 km path, both rapports 579. He is new on the band and would like to try
Dear John, I guess the modern method is to use so-called "delta-U" chargers. They charge quicker and finish charging upon a voltage decline delivered by the "delta-U" detector, otherwise the cell wou
Dear Hans-Albrecht, good to hear from You. But obviously You have missed us! In the Munich area DK1KH, DK6NI (Erlangen), OE5ODL and me have been around in normal CW for one and a half hour today (6.

Dear Petr, I have just built an LF amplifier using a TBA810S to drive my antenna metering bridge. Output has been 3,5 watts at 136 kHz and 15 volts supply voltage. 500 kHz was not on the table at tha
Dear Walter, I guess You should feed your energy-saving bulbs from the mains via a current balun of at least some hundreds of microhenries when running your transmitter! HW? Ha-Jo, DJ1ZB "Walter und
Dear Henny, my QTH is about 400 m from a railway line, and I regularly saw their 16.667 Hz power frequency and several ELF harmonics. The E-fields are relatively strong as the lines normally do not c
Dear Petr, at the input of my VLF-LF converter I have just a simple low pass filter with a cut-off frequency of about 80 kHz. This is sufficient even for a low-power mixer IC like an NE602 or similar
Dear Petr, I guess the easiest solution would be to seperate receiving and transmitting. For receive it is not necessary at all to tune the antenna. I am using my LF T-antenna for receive from 10 kHz
Dear all, Both signals were weak but readable, from time to time a letter was missing due to quick QSB. the first time. Condx, however, are no longer as good as in deep winter. HW? 73 Ha-Jo, DJ1ZB
Dear Gus, good copy of your CW signal on 505,5 kHz around 22.20 UTC here in eastern Bavaria, JN68GN. SSB is difficult to read in QRN. OK? 73 Ha-Jo, DJ1ZB "Gus" <[email protected]> schrieb: Dear LF grou
