I heard this =very weak= on Sunday night. Not listened since. Yes, I have noticed it, too. I spent some time checking my antenna and matching arrangements as I thought I had a problem. But Tx curren
Hello Rik, hello all, just a reminder: the station Rik is referring to as "DCF39" does not exist+ The callsign is "DBF39" (139,000 kHz = center freq/ fictitious carrier, -170Hz=carrier, +170Hz=data,
Greetings LowFers, Observed the mysterious RTTY signal until 0140z last night. The signal showed strong QSB from "undetectable" on FFT screen to "colour red" in a time window of approx. 10-15 min. Ma
The carrier/rtty on 137,000 kHz - as mentioned in previous emails - could not be detected here (Thursday)+ But, instead, I can see a single, steady carrier on 136,997 kHz - even during daytime+ Is t
Hello Group, I hit the "SEND" key by mistake before the mail was ready :) Sorry...! Here the full contribution follows: The carrier/rtty on 137,000 kHz - as mentioned in previous emails - could not b

Group, Lots of QSB, first looked at 2100 hrs UT and was able to hear this signal, was not there at around noon local time. Monitoring the signal and at 2315 UT it is weaker than at 2100 hrs, local G
the carrier at 136.997 (I agree at +/- 1/2 Hz!) is almost always present here, and very clear ("O"!) in 0.3 Hz BW. I had no time to listen in past weeks. In last two days, no sign of RTTY signals her
Hello Gang, I checked the band last night carefully : - The carrier mentioned by Peter / Marco on 136998Hz is not audible here but it is visible on spectogram with some QSB, readability between 'T' a
Hello all, Renato IK1QFK was able to check the direction of the 137 kHz RTTY signal this early morning. Around 0500z he found a good null in N/S axis, so the signal seems to come from E or W +/- 20 d
Hello all I have been hearing the signal .It becomes audible around local dusk and has a lot of slow QSB until around 0200 GMT it then is quite strong about an S9. The other nite I was testing a 35 t
Hello Lowfers, the RTTY signal on 137 kHz was (is) quite strong this morning, I still can hear it right now (at 04.50 UTC). I made some measurements on it: Mark: 136.949 kHz Space: 127.025 kHz Shift:
Hello Lowfers, this morning I was able to record the signal strength of the RTTY on 137 kHz signal when it faded out into the noise. This was around 05.24 UTC. Maybe someone can correlate this fading
