Hello Paul, all, JT9-5: my mistake! I was running SlowJT9 v0.9.12.5 for JT9-5 and that version will not decode below 400Hz. I should have known better ... I will install a second version of v0.9.14.0
Hi Chris, the link is http://www.472khz.org/SlowJT9/ 73, Rik ON7YD - OR7T Hello Rik , Any chance you could e-mail the link to the latest SlowJT9 please? Maybe you could add a link to your Software do

And be sure to use version 0.9.14, older versions will not decode below 400Hz. 73, Rik ON7YD - OR7T Hi Michel, Are you sure about settings for JT9-5? There is the period 0620 - 0720z which looks as i
Dear all, Beta-release v0.9.14.1 of SlowJT9 has been uploaded, see http://www.472khz.org/SlowJT9/. The only change is exptended (and hopefully improved) adjustment of the waterfall and spectrum displ
Hello Paul, there was another (and even better) band opening after I left for work (6 UTC): 0550 -34 -0.8 395 5 VVV N1BUG 5 0710 -33 -0.8 395 5 VVV N1BUG 5 0730 -29 -0.8 395 5 VVV N1BUG 5 0750 -33 -0
​Hi Wayde, my RX is still running on 136 kHz dial, JT9-5 and JT9-10 modes. I will leave it running overnight and report any "catch" in the morning. 73, Rik ON7YD - OR7T Van: owner-rsgb_lf_group
Hello Wayde, I just tried JT9-5 (1st and 2nd cycle) and it seems to work fine here (one sequence TX, one sequence RX). If you can reproduce the error: please stop the application when it is sending t
Hello Lubos, nice to see some activity at the "old" 500kHz band. By the way: in Belgium we still have the 501-504kHz band. 73, Rik ON7YD - OR7T Hallo friends! My MW beacon OK0EMW ( 505.060kHz) is on
Hi Stefan, the radiation resistance of a small loop: Ra = (320*Pi^4*A^2)/lambda^4 where A is the loop area in m^2 So for lambda = 630 m and A = 4 m^2 the radiation restistance Ra = 3.17 ľOhm (micro O
Hello Stefan, my calculations assume that you are using a single turn loop. 73, Rik ON7YD Hello Rik, Thanks for your calculations. Looks like the 1000 km distance is already done. Of course i also ma
Dear all, Beta-release v0.9.15.0 of SlowJT9 has been uploaded, see http://www.472khz.org/SlowJT9/. Changes: - PSKreporter.info spotting added. - Flexible frequency boundaries for the spectrum display
Hi Paul, all, SlowJT9 vs WSJT-X: as I mentioned it was pure luck that SlowJT9 performed better that night. But as the only reason I can think of is a small timing difference between both it might be
Hello Les, all, WX permitting I will be QRV on Saturday (here in Europe) starting 5h30 UTC. I will monitor JT9, JT9-2 and JT9-5 all night. 73, Rik ON7YD - OR7T _______________________________________
Dear all, Beta-release v0.9.16.0 of SlowJT9 has been uploaded, see http://www.472khz.org/SlowJT9/. As mentioned earlier I was intrigued by one sentence in the mail from David, G0MRF, (17 Januari): "I
Hello Chris, so you trained the dog to watch the screen all night and wake you up when a DX call appears? I want such a dog too, what breed is it? 73, Rik ON7YD - OR7T Give that dog my thanks too! Em
Aha, I got it. So I should be looking for a Japanese Terrier, I just hope I won't need 9 of them ... 73, Rik ON7YD - OR7T Rik, It depends on the mode. We use to use WOLFhounds, for example. John, W1T
Hello Eric, I had a similar problem: at "key up" one of the driver outputs will remain low and the other high. As a result the gate of one of the power MOSFETs is kept high for a time much longer tha
Addendum: 3 microseconds is for 472kHz, for a 136kHz PA it should be 10 microseconds. 73, Rik ON7YD - OR7T Hello Eric, I had a similar problem: at "key up" one of the driver outputs will remain low a
