LF: JT9-1 sporadic decodes

["Markus Vester" <markusvester@aol.com>]

Thanks Rik and Marco for the reports. It looks like you've been decoding each of our transmissions.

 

Stefan and myself were less lucky, and still struggling with only sporadic decodes. He was getting me once, then no more for a while. We are both strong signals to each other, but reducing my power by 12 dB gave no improvement. I was seeing nothing at first, then several successful decodes, and nothing again during a later attempt around 14:55. The failed decodes usually show 10 sync points and the correct QRG but simply no decoded text.

 

Software version is r2713. I have uploaded wavs of three consecutive failures to

Best 73,

Markus (DF6NM)

At 1358 and 1400 I saw a weak trace on Marcus' frequency, maybe reduced power?

I assume that AAAAARGGHHHH it not an expession of happiness ;-)

DK7FC is starting further JT9-1 transmissions on 137.44 kHz.

Reports apprechiated, especially from stations who mostly received
15P6715P67WCV so far ;-)

I'm also trying to receive between the calls and hope to get first
decodes from other stations. I can't watch the RX window all the time
but will take a look from time to time.

73, Stefan/DK7FC

PS: Can't monitor 501.4 kHz, sri.
