Dear Uwe, here is what I fugured wx- condx: surface wet snow 1 - 2 cm. Antenna: Umbrella 20m, top 300 pF, R/in = 24 Ohm RX: Praecitronik MV 62 locator: JO40LE Time ur signal noise DCF39 2200 -86 dBu
Alexander, how much topload on your vertical? Mine is 22m high with 300pF top. R at feedpoint is 24 Ohm. After some tests (compared with DCF39) and calculations the radiating restistance seems to be
Hello Dick, between a peak and a plate it takes 1 kV. Between two balls ( diameter?) - spheres - abt 3 kV. per mm. Don't ask me for kV/m. 73 Peter, dj9dw. -- Original Message -- From: dickrollema@cas
Valerio, have a look at http://www.rainer-foertig.de/unterlagen/DDR-RFT-6.htm Good luck, Peter, dj9dw Hello all, I bought an LF-HF receiver EKD300 but the PLL chain of the first Local oscillator does

Hello Roelof, would you please send me that article too? Tnx in advance es 73 de Peter, dj9dw [email protected] you mailadress in dx-summit did not work, by the way.
Hello Alberto and all, they choose this exotic transistor because of its extreme linearity. 73 Peter, dj9dw Hi Uwe, probably you haven't found it because it is referred to as "Amrad active antenna".
Hi Roelof, did you receive this via miniwhip? 73, Peter dj9dw Hello all, The receiver was switched on in QRSS60 at 07:00 UTC and just caught the tailend of VO1NA. I also found a DFCW signal at 137779
Hi Roelof and group, in my location - JO40LE - close to Mainflingen -DCF - I had to increase BW for better rx-performence. The noise was caused by databursts from that nearby commercial LF-TX. Narrow
Hello LF-ers, found some info abt DCF 39 at DK8KW's site. Not brand new, but as far as I know, there has been no change in parameters. So have a look at http://www.qru.de/dcf39-beacon.html 73's, Pete
