Hi Stephen,

V1.04 upgrade received and installed all OK. Many thanks.

Worked first time with my GPS, frequency, locator and time all correctly
updated.

There seems to be an additional Menu setting of "Cursor" with a default
value of "4".

Before I play with it and screw things up can you elaborate please?

Thanks again.

David,

Thanks Stephen.

Since last post, WSPR now up and running (across the shack). QRSS into
dummy load and RX made deaf. No padding to call sign field was needed, only
5 characters G8OQW entered.

WSPR 2.11 is copying signal 100% at -21 to -26dB with a frequency stability
of 1Hz.

I have encountered something strange which I suspect might be a receiver or
PC sound card artefact but open to comments as I'm not too familiar with
WSPR:

WSPR is showing two signals separated by exactly 100Hz both decoding
perfectly as my signal but one typically 5dB down on the other.
eg. one at -21dB and one at -26dB both show same DT. RX noise is 0 to -3dB.

Investigating further...

Regards

David,

I believe that Hans put that there because some people found the original
cursor a bit difficult when inputting parameters. So that gives you a
choice.?

Thanks for the feedback, it really is invaluable.?

It may be related to the sound card but that would also show up on off air signals from other stations, particularly on strong signals. I have found that sometimes 100Hz sidebands may be produced if there is hum on the power supply. It doesn't take much hum to show up, particularly on the feed to the 2N7000.

It is very common on WSPR to see a double decode several db down on a very strong signal. It is particularly likely when you are swamping your own receiving system with a local mept like this. It happens on mine too. I think it is caused by overwhelming the sound card with a strong signal. Turn the RF gain back on your receiver and it will disappear. It doesn't mean you are transmitting a wide splattering signal, so no need to worry about it.

Thanks to Tony (BZB) and Dick (BBH) for their thoughts.

I'm confident I'm not overloading the receiver, I've made it as deaf as
possible and the QRSS TX is well terminated. The signal the RX is seeing is
well below often heard off air signals. Swapped for another PSU as well
with no change. It's not the U.QRSS either so most likely something weird
with the sound card / chip.

There was one benefit of the investigation which revealed one of my bench
power supplies is a little sick exhibiting a repetitive 22MHz burst of low
level oscillation. So something else to look at!

This effect has been discussed several times on the WSPR website.
