Hello Reino,
Thanks very much following up. I will do my best to answer your
questions. Feel free to ask for more clarification as needed.
Number 5. I am not sure whether or not I saw both rx and tx early on
the waterfall. I will have to wait and look again. I do know that the
6 second early dt shows up in the station received list. I have seen
the delay but not sure if it was one or the other or both rx and tx.
I took a look at wspr.live and could not really figure out how to use to
check my own transmitted signal. I’m very familiar with using databases
and did some consulting after I retired, but the whole interface to
wspr.live is not clear to me. The advantage would be I could see the dt
received by other stations. I don’t know how they get it as it is not
sent to wspr.net. I was hoping that someone else would hear my signal
and be able to report the dt to me. I don’t know if you can hear me on
wspr. I run only 500 mw but could easily raise it. The xmit power is
quite accurate I believe as I am using an LP-100a to set it.
Number 6. I’m not quite sure I understand you question. I can only
record dt on received signals and it is not on wspr.net. There are
horizontal lines on the waterfall on the even minutes with the band
displayed at the left. Those lines are timed correctly with respect to
the system clock, but the sequences I receive (and transmit?) are not.
Again, I don’t know if it is only rx or tx but the early start is
clearly visible on the waterfall.
I don’t know much about FST4W. Is it rx only from particular beacons?
I still would need to get dt from both tx and rx.
Finally, I am pretty sure this is a software bug. It is as if there is
a variable/register that accumulates dt offsets and at six seconds adds
a shift of six seconds to the received dt. I would not be surprised if
it added another six seconds after another two days.
I’m not that good a programmer to dig into wsjtx, besides I am 86 and
would rather spend the time doing other things.
Thanks again and 73
Paul
