rain agn=2E the transmission has been switch= ed off at 21:06:42=2E

what abt the second message 20:01 until 21= :02 ?
can you decode that one?

Carri= er of DJ8WX measured in about 80uHz bandwidth=2E S/N is 18=2E4dB in

The magn= etic flux density of 0=2E1fT corresponds to around

With the above S/N, this should decode at about Eb= /N0 =3D +2=2E5dB

At 18:00 I am still = getting carrier=2E When I run this into
the decoder it struggles to = decode, the noise has come up
since the S/N measurement=2E I add in = the E-field to gain a
couple of dB and then the carrier decodes:
=
18:00:00 to 19:01:20

(Car= rier decodes to a string of * characters)=2E
