Hi Roger
Yes we won't do the subject to death yet again but there is up to 18dB
spare on some WSPR reports.
I think there is also a human 'can't be doing with it' factor involved
when a signal is broken and hidden in the noise.

Thanks Eddie.
I think WSPR2 is roughly equivalent to QRSS10, so some 5dB(?) better than QRSS3. It is
possible that people did not detect the QRSS3 signal because of this, but more probable
that the "manual" decode required did not happen.
There is NO doubt in my mind that WSPR in all its flavours is an excellent
research tool because of the Internet feedback.

Hi Roger
I did take a look for you last night but QRM levels here, interference like
heavy theater curtains, means 136KHz is a no go area for me unless whoever it
is stops doing what ever it is.
I am also doing it the difficult way still, running my 200uW TX on WSPR and
QRSS on 475KHz producing regular spots from the UK, DL, PA and F. However
confirming my previous tests the QRSS3 may as well not be there. Not one report
received even from a UK station.
This is with the QRSS between WSPR transmissions in the WSPR window. If the
mode was the slightest bit comparable then surely it would produce a comment
even if those seeing the signal cannot resolve a call sign or the unique
identification Morse symbol.
I will now duck whilst it is mathematically proven that all who are decoding
the WSPR are copying the QRSS3 just fine.:-)

My LF WSPR2 tests using the earth-electrode antenna and 30uW ERP max continue
this evening. With 2 unique reports yesterday (G8HUH 250km and M0GXM 18km,
both multiple times), I'm hopeful that others will copy me this evening.
Please take a look for me if you get a chance. All spots really appreciated.
