I could not decode anything=2E The following carri= er

says that should give E= b/N0 of about 8dB=2E When I run the

which agrees with the signal calculator=2E
<= br>With that strong signal, the message should have been an easy decode= =2E

So, something is wrong with the modulation or bit clock=2EIf you tell me the message, I can analyse the signal=2E

I have= been checking for your long carriers in very narrow bandwidth
at Fo= rest VA (distance 6667=2E7 km) but so far no sign of anything=2E
