Thanks, getting a weak very trace & the decode= r is indicating a signal sync but hardly visible, please keep trying, QSB= may bring you up.

Hi Gary

=A0

Just got two dec= odes of you at -12dB and -15dB 2116 and 2118.

I have replied= with my call and locator on odd minute txing

With best regard= s

Rik, & Andy,

=A0

Thanks for your report & comments & Andy= for answering Rik's query.

=A0

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 afi= eld.

=A0

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.

=A0

Let me know.

-24dB S/N (2.5kHz )=A0 is usually guaranteed

=A0

solid copy here, SNR -5 to -7dB.<= /font>

But the signal is clearly audible, CW wo= uld be armchair copy.

Any idea down to what SNR values JT4A pr= oduces a usable decoding ?
