I was about to report that it was as you said just the tune button... actual TX tones were working in the previous version this morning. I just installed the last... all OK. I will send some JT9-2 an
OK Steve, and Chris said the same. I will change all four this time since I will be going to a different type of FET but in the future will try to identify and change just the bad ones. Sorry I miss
Hello Chris, OK after this first time (switching to the 32N20 type) I will try changing just the bad ones. I'm sure there are better FETs these days but I will let someone with more technical knowled
Congratulations Luis. I copied you the first time in the slot before my sunset. You were in command for some time, then it switched over to Stefan. I just uploaded some additional spots this morning.
Hello Rik, all, Yesterday I could do some tests with my QRP Labs U3S transmitting, SlowJT9 receiving. I used a lot of attenuation between U3S and TX antenna. Then there is another 30 or 40 dB lost be
First I want to thank Rik for his work trying to bring back the slow JT9 submodes! I also want to thank everyone who has been helping with tests. I truly believe these modes can be helpful in making
Update: It seems the new AF limit for JT9-2 is somewhere between 1250 and 1300 Hz. 1250 decodes, 1300 does not. This may explain why my JT9-10 test did not work. It may not be possible to get low eno
Hi Jay, Yes of course night time testing is needed also. I am only thinking first steps to establish some kind of base line for sensitivity. I've seen some conflicting hunches so far based on night t
Hello Rik, all, It's the same for me. I know 2200m is mostly a engineers and experimenters band, but I came as a ham radio operator looking for challenging DX QSOs. Maybe I don't quite belong there,
My nearest neighbors are >200 miles but AA1A at 236 miles tends to be quite stable on 630m during mid-day. Probably not quite as stable as a <100 mile path. 73, Paul N1BUG
We should ALL answer this, with copies to K1JT and K9AN and/or the wsjt-devel list!!! I personally don't like the averaging idea. I am not technically knowledgeable enough to comment on the last part
I spent the last 6 nights making QSOs on 630 meters. While it has been interesting and at times fun, it has also been very frustrating. Many QSO opportunities were lost due to people calling split. W
Yes I will. Not sure yet exactly how much power, probably 4 dB down from my usual. I am setting up a combination of WSPR-15 and WSPR-2. Is 137.607 OK? With so poorly calibrated receivers around, it's
Hi Stefan, Yes now I remember something was said about the DCF sidebands last winter but I could not remember it exactly. I will go to .620 for tonight. Thank you! What I plan tonight is one WSPR-15
No transmissions from me this night. The little amplifier has died. I think it may be related to this resistance change in the antenna which is getting worse and worse. I'm going back to MF for this
Thanks Rolf for trying to work me the past two nights. It seems we are having very bad luck with the QSB. Your RX is better than mine but we did see that I can RX you to at least -23 which is good en
Hi Markus, That is very interesting. It changes about 25 % during the first 2-3 minutes, then it seems to settle down and not change any more. It could be moisture somewhere, but any moisture here is
For what it's worth I noticed the same with an older version of SlowJT9 when I changed the output sound device. The setting did not take affect until after I closed SlowJT9 and restarted it. It was n
