Dear Yas, LF Group, A quick check here shows the DCF39 "space" frequency to be 138830.6Hz, +/-0.1Hz. It is hard to measure more accurately due to the effect of the FSK modulation. Cheers, Jim Moritz
Thanks Alan. I just uploaded sequential captures: http://icas.to/argo/dcf39/ It started to show up about one hour before the sunrise. My question is if DCF39's space freq exactly falls on 138,830.5Hz
Hi Jas it is difficult to say for sure but I think you can be fairly certain that is DCF39. I dont think there are anyother signals like that on LF anywhere else in the world and the fact it fades ou
From Dave G3YMC Greetings All: DCF39 was not visible at all last night, 31/1st. Was it possibly off the air? DCF39 has returned to regular spot tonight although the signal is weaker than usual. Larry
Laurence I've been looking for WD2XDW most nights recently, still nothing but the DX Loaran lines are staying in longer and getting clearer by the day. 73 Dave G3YXM Made its first pre Eu dawn appear
I have also been running captures looking for Laurence most nights recently but so far nothing seen except an unidentified line about 0.2Hz above his nominal frequency. In the words of the old jazz n

Hi Mike, It could be, DCF39 is a 24/7 signal, and the spreading looks like that Laurence was reporting in Anchorage, and is due to the "randon" return of the carrier phase after data bursts ( Markus
Mike at dot 60 normal on Argo and weak it looks like a spreaded mostly filled in 0.1 Hz wide carrier signal. As it gets stronger (if) sideband "noiz" appears and bars above/below the main signal appx
Mike, This is how it looks in the Eastern U.S. on an Argo 120 second screen. I'd say that we are looking at the same signal. John Andrews, W1TAG JPEG image
Hi all, A signal on 138.83 kHz got stronger approaching ZL sunrise. A weak trace started from about 1715 UTC. See the 1854 UTC capture (which includes scales and time) for 10 second dot length. It lo
Hi Mike and Laurie, It will be interesting to see what happens on your sked. This is probably the best time of year for that path. however the condition look to have taken a downward swing again. Bri
Dear LF enthusiasts, I agree with Alan - "It will be interesting to see what happens on your sked" Some datas: Sunset in QTH Laurie G3AQC at March 8 - abt 1750z Sunrise in QTH Mike ZL4OL - abt 1830z
Dear Laurence, All seems normal here at this moment (2025utc)... Cheers, Jim Moritz 73 de M0BMU -- Original Message -- From: [email protected] Laurence KL1X To: rsgb_lf_group@blacksheep.
Hi Jim yes I had a look about 1520z when I read you message and it was pounding away then it went off again. There is no obvious lightning activity in that area according to wetterkarte it is all to
OK Laurence, I am set up for 136.320KHz, qrss60, 300W, send WGT & cw id at 6wpm. Start in a couple of minutes. Gud Luk. Gary --Original Message-- From: [email protected] [mailto:owne
Hi Laurence, I can send an hour or so at qrss 60, what freq? Gary - G4WGT --Original Message-- From: [email protected] [mailto:[email protected]]On Behalf Of Laurenc

Dave - Alan - its not bad - I have peaking S9 but the R75 is doing a good job - this is a new rx so great to see dcf39 and get it cal'd. Im running captures on argo 1 on the kl1x.com web site>>. and
