Hi Marco, Oops, does that mean my mains hum sideband rejection is only 25 dB? No, i measured 35 dB here. And it will become much better soon because i will build a new type of power supply soon... Th
Hello André, OK, i'm going to 20%. Is there any preferred frequency where to go to? Maybe i should go closer to the lower end, arround 137.410 kHz? 73, Stefan/DK7FC Am 18.09.2012 18:49, schrieb André
Hi Stefan, I am using VAC for rx and tx without any problem, the distance to you is abt 450 km so my signal should be between -10 and -15dB at ur RX. I hope you will improve ur RX capability on OPERA
Stefan, I doubt that VAC is the culprit. Using it since ages without problems. Look somewhere else. Here is a decode of your transmission. You are about 2 sec out. Maybe that is the cause. 1946 -4 -1
Hi Stefan, it's quite incredible but if you have look on the spotdatabase you wil see my uploaded report: at 21.46 UTC you are -3dB on your QRG (137449) and decoded with -28dB on a (HUM carrier) on 1
Hi Klaus, and Marco/IK1HSS, Thanks for the feedback and reports. It looks like timing is critical here. I don't know why the time delay is changing. Maybe it has to do with the separate tool to gener
Hello DK7FC Stefan. Congrats, but I am sorry because your LF WSPR signal is very strong here in JN19QB (about 180 µV in SPM3), and of course I cannot copy any other station when you are transmitting.

Hi Stefan, here the report from jn35tb UTC Date: 2012 Sep 18 -- 202600 13 -17 -1.8 -570 0 DK7FC JN49 30 will try now to run wspr and upload the decode (this was catched with wsjt7 software cu marcoei
Hi Stefan, you may run SpecLab utility, listen to DCF77 (you should receive it .... .. .... ..) and sincronize the pc clock! it take a couple of minutes and with warm PC is fine for at least 12 hours
Hello Albert, I'm receiving in WSPR between my transmissions but somehow i do not get many decodes. It is the same like in Opera. Maybe it has to do with the virtual audio cable software i have to us
Hi Roger, LF, All my PCs are running a time server program. But the tool that generates the WSPR tones here is not affected by the time. I must use the WSPR program to generate WSPR-2 to correct the
Dear LF group, A few days we started a discussion about a slower WSPR here in the group. After that, i've been in contact with K1JT who meant he will work out a slower WSPR version for LF, in a few m

OK, OK Thanks for the tutorial Stefan. Didn't want to bother you into such details; but anyhow: tnx for it. Right now I am only SWL (or should it be LWL or MWL??, hi!) on the low freqs. See you on al
Stefan, I fully agree with Andy, less is more. "The goal of WSPR is to transmit with low power and also to listen the band for giving some RX reports to other transmitting stations." 73, Albert PA0A
Hi Stefan, what DIAL frequency must be set in RX for receive your WSPR packets ??? 73 de Mauro Ik1WVQ So now i joined the WSPR group and start to do some test transmissions with the normal 2 minute W
