Alan and LF group: now for the real excitement!! By chance at 1449z today I noticed that there was an FSK signal visible on FFTDSP4 on exactly 137.00 +/_42.5 Hz shift FSK. I dont know when it appeare
Greetings: Preparations continue for TransAtlantic II, the test transmissions from here in Eastern Ontario on 137.710 kHz are now heard widely in the USA and Canada. Moving forward through the lists
Greetings all Hi all Jack has posted his usual sked times to the DX Cluster (10 min tx starting on the hour and half hour) starting at 2100z this evening 31 Dec. for some reason Jack stopped sending
Greetings: Simple and succinct. A 16 bit A to D converter board that Alberto di Bene, Bill de Carle can make their software work with so we can go to the next level of digging in the noise. With the
Greetings All in Europe: I will be listening tonight from 20 utc onwards on 136.500 from 10 after to 30 after, then 40 after to the top of the hour. I have copied a number of one, two and three lette
Peter, G3LDO I am not sure who is the source of offensive behaviour, I do not see some of the emails on this reflector (you can guess were they go automagically), but your LF source book was and rema
Greetings: I have a note from a chap who tells me that there is someone on here who wants to try regular CW over the North Atlantic. I do not see all the messages on this reflector but just in case i
as Alan has observed before, transatlantic condx appear to be quite good lately. Last night's spectrogram showed CFH on 137.742 peaking 26 dBuV/m I trust your meaning 137.042. This tone cum carrier

Alan: If possible would you please turn OFF your message acknowledgement request with each of your email submissions to the RSGB LF reflector. Each one of those requests is received over here and tri
Greetings Laurie: Well, not much on 922, a frequency line at times but nothing very clear at all last night. However there were a pair of excellent frequency lines on 921 early in the evening at time
Greetings: A while back I incorrectly stated that DFCW as a two tone system was not useable for the weak signal work I am doing. My assumption, and it can be no less than that was wrong, Rik, ON7YD h
From Marco, IK1ODO comes Hi all, Larry come out of noise this morning around 0630z, when street lights come off. But at least some more dB are needed for a QSO! Picture at http://www.spin-it.com/LF/l
Rik: followed by to avoid misunderstandings : DFCW does not need linear amplification. I have just looked around and I can not find the file I referenced, please send me a description of DFCW, I am o
Mike: However, the earlier part is a bit flawed. Are you assuming that this type of communication can only be done on sked, or can there be a random QSO? Flawed? Well that is the issue isn't it. We h
Greetings All: After consultation with a number of peers I propose the following as the minimum for a QSO validation over the North Atlantic on LF. Step 1 M0BMU VA3LK va3lk sending Step 2 VA3LK M0BMU
More general : it seems that it is possible to cross the pond with stations running less than 1W ERP (believe that BMU and AQC are abt 400-500mW) but it needs rather long dotlengths (1 minute). So we
Greetings All: The following is presented as an alternative and supplement to the use of a BPSK schema for having a QSO across the North Atlantic. The following proposal is presented as a way to make
Greetings All: My noise level has dropped very low here, I am seeing clearly signal lines that I normally have not been seeing on 135.9218 to 135.9232. Anyone in the UK who can transmit this weekend
