Thanks for your report & comments & Andy for answering Rik's query.
Well there has not been any response to my CQ call so I will change the text to beacon & continue to see if there is a report from further afield.
If you want to try for a weak decode I can reduce the power for a short period say 30 minutes, my power is 50 watt RF (200 mW ERP) at the moment so in view of your good
report I could take it down to 10 watts RF.

solid copy here, SNR -5 to -7dB.
But the signal is clearly audible, CW would be armchair copy.
Any idea down to what SNR values JT4A produces a usable decoding ?
LF,
Running JT4A this evening on 503.600 kHz, dial frequency 502.300 kHz USB.
