Hello Steinar, Markus, LF,

That is all very strage. After the transmission in the afternoon and evening using JT9-30 i think i will go back to the usual modes until Joe has some good ideas :-)
Have to work on the step down converter that works better and better now!

73, cu, Stefan

I managed to decode your signal
even if it looks like you are slightly out of sync.

Similar here, most (but not all) slots decoded successfully,
but mostly with asterisks. Strange that the quiet slots at odd
ten minute multiples also achieved 10 sync points - perhaps the
echo effect again? The first line went wrong only because my decoder
was still set to 5 minutes.

Even with 1 Hz tolerance the CPU is getting pretty busy - maybe in a future 
version we could select whether we want multiple decodes or not? On one of my 
machines I can't use 48 kS/s for WSPR and WSJTx because that samplerate is too 
far off, so being able to choose between 12 and 48 kS/s aquisition would also 
be useful.

Best 73,

Betreff: LF: RE: JT9-10 Decode DK7FC

Decode OK but same again – Sync and dB values shown as **** (usually indicates 
values exceed expected)

0120*********   0.9 1138.38  0.00    DK7FC JN49IK

I have reduced the tolerance to +/- 10. I checked JT9-30 and the Wide Graph 
scale shifts again requiring another retune and increase of FFT Bins/Pixel to 
get 1140 kHz on screen (136.3 + 1140)

A decode of your JT9-10 transmission. I wonder why the Sync and dB values are 
shown as **** ??

0100*********   0.4 1138.38  0.00    DK7FC JN49IK

Waiting for JT9-30 ??

I thought you would prefer to stay with BS – sigh!

Stefan getting regular decodes from you – every 10 minutes. Will also try your 
JT9-10. Let us all know if another frequency offset is required.

No, i'll stay at 137.44 kHz over the night.



Sending emails is a pain!
Is it? I like it :-)
