Hi Arthur, I guess there's nothing to stop you (or me!) Tx'ing on 1908kHz but I suspect most, if not all, of the JAs would be listening on 1840kHz so there would be little point on Tx'ing on 1908kHz because the JAs probably wouldn't hear you.  Also, our licence conditions only allow us to use 32Watts between 1850 and 2000kHz so the chances of a JA hearing that are, I suspect, pretty slim!

Hi

I just got Win10 update and now when TX'ing FT8 and at the same time updating web page in Chrome (Firefox too) breaks the TX for a sec or so...
Surprisingly surfing with the Edge Beta does not have this issue at all.

PC is i7 3.4GHz 16GB ram and has no issues b4 this.

Make sure your computer's clock is dead on. If not the radio won't jive with the computer. I had to switch internet time servers on mine because the factory default time server wasn't accurate enough. Anything over a second difference can be a problem. The server that I use is https://time.is/

With you power turned down, test by pressing the TUNE button. The radio should switch to TX and transmit on 1908 and the WSJT-X freq window will also 1908. When you switch back to RX, the WSJT-X window should read 1840 for receive. Hope that this works for you.
Hi Rich, in your second and third sentences above haven't you got the frequencies the wrong way round?  The JAs transmit on 1908kHz so that's where *you* need to listen with VFO-A, and the JAs receive on 1840kHz so that's where you need to transmit with VFO-B, exactly as you've described in your first sentence.  That's how it works for me, anyway - I listen on 1908 and when the rig is keyed by WSJT-X its frequency shifts to 1840, with the WSJT-X frequency window also changing to 1840 until it switches back to 1908 at the end of a Tx period.

I strongly recommend DXKeeper. I was lucky to discover it soon after getting back on the air in 2003. It's one of several loggers supported by JTAlert and/or WSJT-X. Excellent (automagic) integration with LOTW, eQSL, ClubLog. It's FREEWARE.

A good reason to have one main log and log to that in real time. IMHO DXKeeper is the one that should be but there are others. Logging in real time to the main log and having a backup strategy is the way to avoid your problem. You may have no recovery at this point but I will let someone with more knowledge of the app to answer that.

My wsjtx_log.adi has all QSOs back to 2016. I just did a reconciliation about a week ago between the wsjtx log and my main log with no discrepancies (just over 15000 QSOs). I actually log via JTAlert to DXLab. Perhaps you reset something during program updates? Someone had a scheme for deleting wav files and if you did that perhaps it got some of the log data as well?

Joe,

If you by hashing mean the same as interleaving, then the reason is to distribute short QRM or QSB affects all over the transmission period as the error correction works better with single error bits than many continuous ones.

Ah ha!  That explains why sometimes (often?) I get a response from a message sent to a station that I was very late clicking on (within the current transmit period).  Is the point of the hashing of the data in the packet to randomize it for some reason??

Thanks for the insight!

Did you check your task bar to see if another instance running? If there was, you can click on the instance and 'end task'.  No rebooting is normally needed.

It won't decode at all if the mode is not correct.

Doesn't affect the decoding alternating. Whatever it decodes first, it doesn't decode the next one.but will decode the third one. I know it's weird.

Hi Bill,

the transmitted message contains the information in the message, the error correction bits, and a checksum. These are distributed throughout the message payload, so it is not correct to say that some portion of the message only contains some portion of the information sent. At the receiving end there is a probability that the message will be decoded if up to roughly half the transmitted message is received with a reasonable signal quality. The probability of successful decoding is reduced by missing information but not by a great deal.

Hi David,

Look the Band Activity display and Freq column there. You will see on the first row you receiver frequency, if any signal there, and then starting from some value increasing frequency values. If at some row the frequency value jumps downwards and continues again increasing (if more rows), then the Two-pass decoding has happened.
