Hello Walter, thanks for the report. My 500kHz setup is very experimental. As the UK NoV's may expire by the end of February 2008 I wanted to be QRV asap and make some QSO's. The PA is a modified 137
Vern, almost omnidirectional and 90 degrees takeoff. But don't believe too much of that. 73, Rik ON7YD I use a 2000' and 1000' unterminated longwires that simply lay on the ground and are used specif
J.B. , I simulated the fence wire with MMANA. On HF (80m, 40m) I got the expected (bi)directivity and low offset angle. But on 500kHz the horizontal pattern is almost omnidirectional and the offset a
Hello David and all, I just did a check with Argo on 600m. The MRF beacon on 503.8xx is clearly visible here, see attached. 73, Rik ON7YD - OR7T Disclaimer: http://www.kuleuven.be/cwis/email_disclaim
Dear Ha-Jo and all, I will stick to regular CW as long as the PA heating problem is not solved. I will try to listen on 3533 but I will have to use the 500kHz antenna. If I listen on 3533 I will anno
George, ultrasonic waves are "shockwaves" (just like sound, only at higher frequency) that change the density of the medium. A complete different mechanism than electromagnetic waves. If you add ener
Mike, it started on 15 januari 2008. All holders of a "full licence" can use the new allocation within the given restrictions (max. 5W ERP, CW only). No notice or special permit required. Interesting
BTW: together with the 500 kHz segment we got topband up to 2MHz (upper limit used to be 1875 kHz). 73, Rik ON7YD But the EU is not the United States of Europe (yet!). And I recall a time when in the
Dear all, today we (UBA) received notice from BIPT (Belgian Ofcom) that we can use the segment 501-504 kHz on a secundary base, CW only (all speeds, so including QRSS). Power limitation is 5 Watt ERP
Hello Laurie, what version of QRS are you using (and what version of windows)? From your description of the problem it might be caused by: - using a Win3 version of QRS with WinXp or Vista - another
Mal, I won't be home during daylight ... family visit. Maybe next weekend. 73, Rik ON7YD - OR7T Hi Rik Pse try tomorrow morning for a qso during daylight. I will listen for you on your freq 503 khz 7
Dear all, propagation on 500 seenms to be good tonight. Just worked GI4DPE (559) and G3KEV (599). In particular Mal's signal was booming, when he tuned in I thought it was Gus calling ... I will list
Hello Mike, what's your QTH? If it is not to far north or west a QSO could be possible at the right moment. On 2 occasions I could hear the G0MRF beacon in CW, I believe it's running just a few mW. M
Great news! I was afraid to get lonely on 600m on March 1st ;-) 1 W ERP should give strong signals all over Europe and maybe even further. 73, Rik ON7YD - OR7T http://www.ofcom.org.uk/radiocomms/ifi/

Hello Wolf, not yet ... My only antenna at the moment is the 500 kHz antenna and it is absolutely deaf on HF (as it should be). My stations is still put together with pieces of string. Next weeks wil
Dear Hajo, thanks for the report. Just worked ON4KTJ, but even here he was only 339 over abt 70km distance. His QTH is Ath (abt 50km SW of Brussels). Maybe southcoast G's can copy him. Anyway: my 14t
Dear all, as I tried to tune my 500 kHz antenna last right I noticed that it was detuned by about 1.5 kHz (from 503 tot 501.5) and that the antenna current was down to 1.8 A (from 2.1 A). A first vis
Paul-Henrik, thanks for the report. I just worked G3LDO, Peter was 559 with some QSB. Also heard G3ZWH calling xband earlier tonight. 73, Rik ON7YD - OR7T Hear you calling CQ on 502.95kHz at 2125z We
Dear all, I have been calling CQ once in a while last night (on 502.95 kHz) and once I thought to hear a response near 501.9 kHz. Unfortunately QRM is very high in the lower part of the band. Lowest
