Hi LF Group On the base of my own "generalased mirror reflection theory" I just have derive the formula for ground loss resistance: R = (lant/lcp)*a*Xc where: lant - wire length of antenna, lcp - wir
Hi James and Group. It seems to me that in this case, where most of the antenna field (and therefore the displacement current) is going to the ground rather than the counterpoise, most of the return
Someone more... With no counterpoise, the antenna loss resistance at 136kHz was 37ohms. With the counterpoise as above, Rloss dropped to 32ohms, a reduction of about 14%. With antenna current of 5A,
Hi James and Group. With no counterpoise, the antenna loss resistance at 136kHz was 37ohms. With the counterpoise as above, Rloss dropped to 32ohms, a reduction of about 14%. What coil resistance You
Hi, Giulio. Has someone tried the E-field probe vertical whip with high impedance fet preamplifier, comparing it to a classic multiwire receiving loop, here in 136 Khz? I would like to made an E-fiel
Hi, Wolf and Group. Like all others, I had solid copy on Ed's signal but never tried to call him (he had enough callers with higher ERP than mine from DF0WD). If you saw a signal from DL0WD (not DF0W
Hi, Group. I?m sorry, but the tolerance of my measure is + or - 1.0 Hz. Now, at 2.25 UTC is beginning the 6 of the call, at a rate of 60 seconds per dot. By my measurement FREQ was 135.918 kHz +/- 1
Hi, Group. This night I copy Ed RU6LA (RU6LWZ location) audible most of time. It was nice codition. I saw (and hear) Ed in QSO with DL3FDO, OK1FIG, DL0WD. QRB ABT 2500 km. At QRSS60 test transmission
Hi, Group. There is my log here. 29 Sept 2002 18-37 GMT 137.69 M copy RU6LWZ 19-07 GMT 137.69 O copy RU6LWZ 19-17 GMT 137.69 O copy RU6LWZ 19-32 GMT 137.69 O copy RU6LWZ 19-35 GMT 137.69 O copy RU6LW
Hi, Group. If sombody know E-mail of OH1TN please send it to Vlad. It seems OH1TN is nearlest STN to Vlad (exept RU6LA). 73 de RA9MB/Alex http://www.qsl.net/ra9mb
Hi, Group. INFO from Vlad. Because 135.5 is common CW FREQ today he will transmit on 137.71 kHz. As Ed get Vlad's sigs on 135.51 when nominal FREQ was 135.5 today Vlad will set nominal 137.7 wich cor
Hi, Group. deacreased (antenna current about 1.5 Amp). This night Vlad will continue beaconing on 136.51 kHz. Also it is posible computer will be carried today. So it is good oportunity for 2-way QSO
Hi, Group. Last night Ed RU6LA sucsesully copy Vlad's QRSS (QRB ABT 500 km). Ed mesured FREQ. It was 136.51 kHz. Worth to note ysterday Ed recieve Vlad from noisy home location, not from Machta. Also
Hi, Alan and Group. Hi Alex thanks for the gen about the instability....... that would wipe him out on QRSS completely. I think that it would be better to stay with 136.100 if possible if he starts j
Hi, Giulio and Group. Hi Alex and all, soon i'll measure exactly the antenna current, but one things that appear in this discussion, is that the antenna work very well, it is only a single wire 60 me
Hi, Group I wonder why my message on RX3QFM does not go to a Group? Two times I try to send and there is no echo for a long time... But another MSG go sucsesfully. I'll try ones more... I have notice
