​​Hello Oscar, I will be monitoring 475.000 kHz from now till 06:00 tomorrow. Good luck! 73, Rik ON7YD - OR7T Van: [email protected] <[email protected]>
Hello Oscar, I started monitoring last nigh with the DX on 472.2 kHz dial and Argo / SpectrumLab at 800 Hz (centered) audio ... to find out this morning that the RX was in LSB (thus I monitored 473.4
Hello Juan, what about a PARDT minwhip antenna: http://www.472khz.org/media/pa0rdt-Mini-Whip-Manual.pdf​ ? 73, Rik ON7YD - OR7T Van: [email protected] <[email protected]
(I heard that somewhere in the Pentagon are getting worried...) :-D Maybe they will offer Stefan a $$$ job ;-) 73, Rik ON7YD Van: [email protected] <[email protected]
Hi Chris, maybe you are better off with a 198kHz notch filter? 73, Rik ON7YD - OR7T Hello DK7FC Stefan, I am seeing better SNR and more WSPR receptions in general with the BPF in place, especially at
Hi Paul, same here, losses are high in summer: up to 70 Ohm (475 kHz) or 180 Ohm (137 kHz). In winter it drops to 35 Ohm (475 kHz) and 120 Ohm (137kHz). I always assumed it was not so much affected t
Hi Stefan, more power is indeed an option, but at that moment increasing the antenna height was a "quick win" (took me about one hour). In addition more power will result in higher antenna voltages (
Hello Paul, getting 1 W EIRP on 137 kHz is indeed not easy for many of us. With my 450W TX I managed to get an antennacurrent of almost 2A in winter. My antenna was a 14m high and 25m long inverted-L
Hi Stefan, for QSO's we would need the slower JT9 versions (JT9-2 and so on), not WSPR. Does anyone know what WSJT-X version(s) supported JT9-2? 73, Rik ON7YD - OR7T Paul, Am 06.09.2018 13:03, schrie
Hello all, I just received the question below. Did anyone already try to get an ICOM 178 working on 630 M? 73, Rik ON7YD Van: JP Rohow <[email protected]> Verzonden: vrijdag 5 oktober 2018 19:36 Aan:
Hi John, Nicolas, Chris, thanks for your respnses, I forwarded it all to N0DZQ. 73, Rik ON7YD - OR7T ________________________________________ Van: [email protected] <owner-rsgb_lf_gr
​If WSPR is an issue (in case of a "straight" CW TX) QRSS might be an anternative. QRSS10, although much slower, would even outperform WSPR in regard with SNR. 73, Rik ON7YD - OR7T Van: owner-r
Hi Mal, all, SWLKQ40LS is Bjarne Melde, living in the very northern part of Norway. Have a look at arcticdx.blogspot.com​ He is using BOG antennas and managed to copy VK4YB and (KH6/)K9FD on 63
Reporting to wsprnet.org via a "public" WEB SDR such as Twente seems rather confusing and even meaningless to me. Reporting via a "private" WEB SDR might be useful (in particular if it is an area wit
Congratulations Stefan, I am even more impressed by the number of spots (over 200) and the SNR values (up to -5dB) you were getting from North America. Based on that a CW QSO should be within reach.
I agree with Roelof, alle LF/MF signals are string these days. Maybe this is related to the fact that we are going into the solar minimum? I remember I got regular TA spots on 500kHz in 2009/2010, ru
Yes, I saw your spots in KQ40. Unfortunately most active EU's live 2500 km more south ;-( Your best chance might be LA2XPA in JP33. 73, Rik ON7YD - OR7T ________________________________________ Van:

Hello all, I just found this on my JT9 screen this morning: 0102 -27 0.3 1340 1 CQ K9KFR EN71 (6590km) 0218 -27 0.4 1053 1 CQ K9SLQ EN70 ( 6616km) According to pskreporter.info there was a lot of JT9
