. . . . . is it possible to make contacts effectively at 136 kHz with a proposed antenna which would only be about 25 feet high and about 50 foot long (horizontal wire or "T" resonated against groun
Hi All, I got the balloons up again on Saturday morning and thus extended my 12 m vertical into a 20 m vertical for 136 kHz. At 06:42 UTC, I had a fine QSO with Harry PA0LQ (RST 559 both ways). At 07
. . . . I discovered that plywood is not a good insulator, expecially after a rainy weekend and with 21 kV on it .... :((( Now, IK1ODO QRT. But QRV again soon, we hope! I had the same 'learning expe
. . . . . Saturday [27] March Heard G3YXM (599), PA0LQ (549), G4GVC (599), G3KEV (599), GW4ALG using his balloon-supported 20m vertical (599 - best yet), EI0CF (549). And a very weak signal ending i
. . . . my vertical is 20 meters high, but the two 10 meter loading wires from the top have to slope down at about 45 degrees ( to fit in the available space ). I have always thought that the effect
Over the past month, I had become aware that a certain G-station - new to LF, but with a very commanding signal on 136.53 kHz - was often heard to 'clobber' QSOs, and CQ calls from other stations. Th
. . . . it is worth considering a time rather earlier in the day when band noise is quite a lot lower. I am on (or at least listening) nearly every day around 7am local (0600z) and this would be a g
To All, I too was sorry to hear the news from fellow 'Early Bird', PA0LQ. Over the past 4 months, Harry and I have managed at least one LF QSO every weekend (except for one stormy weekend in May). Ma
Hi All The QRN has made operation on LF difficult over the past week, so very little activity to report from here. And I'll be away this weekend (VHF FD at G4BRA/P), so I won't get much operating tim
. . . . . My other loony idea was to use a balloon, not like Steve does to hold up the weight of the whole of his 20m vertical (I think), but just to extend the height of a 15 metre lightweight mast
Andre' Kesteloot, N4ICK has recently advised me of the web address for the 3C85 Data Sheet (Philips Components). Many members of this reflector will know that this is becoming a very popular material
Hi All, Over the past 3 weeks I've heard a lot of slow-CW (QRSS) activity on 137.1 kHz - a popular frequency for normal CW operation. Yesterday morning (Saturday), I worked Geri DK8KW; Fred DJ5DI; an
Hello Andreas! The location of the Philips 3C85 Data Sheet is: http://www.acm.components.philips.com/pdf/3c85.pdf (a PDF file viewer, such as Acrobat Reader, is required) At the above page you will a
Geri DK8KW recently asked me how much current I get into my antenna. I am ashamed to admit that, in all my 30 years as a radio amateur, I have never sought to measure antenna current. So the followin
. . . The 5 ohms rf resistance I quoted was the figure for the original single loop. With conductor two conductors in parallel the figure is close to 1.25ohms. Corresponding DC figure is just over 0
Worked DF2BC/P at Campen Lighthoudse near Emden this morning with a formidable signal, RST 599 both ways. I also worked Ali, DF2BC/P, at 0552 UT today. I sent RST 579; received 339. This was my firs
Hi Roger I also listened this morning using my 65 m perimeter loop, resonated to 73 kHz. But I could not hear your signals. Nevertheless, thank you for running the beacon. I will listen again during
Bob ON4DY asked: Who is going to tell me why someone all of a sudden is catched by LowFer, after spending over fifty years of activity on HF, and the other end of the spectrum up to the 13 cm band .
[My] New antenna has definitely made at least one s-point improvement. The difference has been to increase the effective height by (1) reducing the sag by improving the end supports and (2) changing
