Now after identifying problems with high SNR (already solved in the r2711 ? ) i'm continuing a while in JT9-5. Same QRG. I added 6 dB power. The program seems to work a bit more consistent now. The observation of DF2JP, using a directional antenna was interesting! This obviously identified that my signal was not faulty (e.g. caused by multiple phase glitches due to CPU overload) but rather by a to high SNR from my side, which was not observed in WSPR. Also this must have caused the bad RX results here of my own signal or the signal of DF6NM which shows positive SNR values in WSPR here. Joe/K1JT, another point from my side: There are several RX stations using a DC converter with an LO of 125 kHz or 130 kHz. For example TF3HZ, DU1GM, DK7FC, YV7MAE, G4WGT and so on. All these stations have to shift the input signal down to < 1500 Hz in SpecLab and use a VAC to feed it into WSJT-X. It would be desired to allow the RX center frequency to be set to values from 0...24 kHz (48 kS/s samplerate) so the soundcard input can be fed to WSJT-X directly. This will certainly reduce the probability of phase glitches caused by the chain of programs, especially on older computers. You did it for the TX side and this helped a lot here, as you can see. 73, Stefan/DK7FC Am 31.10.2012 23:06, schrieb Ulrich Wandel: > > Hello Stefan, > > nice decodes from you. > > 73 Uli DJ7KA > > WSJT-X v0.2 r2711 > > 136 KHz > > 2120 10 -20 0.2 1439.84 0.00 DK7FC JN49QRP > > 2124 10 -18 0.1 1439.84 0.00 DK7FC JN49QRP > > 2128 10 -19 0.1 1439.84 0.00 DK7FC JN49QRP > > 2132 10 -19 0.2 1439.84 0.00 DK7FC JN49QRP > > 2156 10 -19 0.2 1439.84 0.00 DK7FC JN49QRP > > 2200 8 -23 0.2 1439.84 0.00 DK7FC JN49QRP > > 2204 10 -19 0.1 1439.84 0.00 DK7FC JN49QRP > > RX: IC-7600 > > Antenna: endfed 40 Meter dipole > --------------010008010705040304080407 Content-Type: text/html; charset=ISO-8859-15 Content-Transfer-Encoding: quoted-printable X-MIME-Autoconverted: from 8bit to quoted-printable by relay2.uni-heidelberg.de id q9VNjpqD022603 Hello Uli and the other reporters,
