When trying to recive RU6 signals I have hear someone similar DCF39 about 138.83 kHz. But delay between 'RTTY bursts'is not 10 sec. but about 18 sec. Sometimes the delay is about 4 sec. but not often. I wonder is this stn DFC39 indeed? I copy this stn (audibaly) very nice at night time. I do not measure S/N ratio but its seems to be 15 dB or more... My input filter (135.5 .. 137.8 kHz) reject 138.83 kHz about 10 dB. So real S/N is more 25 dB! Unfortunely I do not hear this stn in day time. Also I can not hear it at evening (befor 01 or 02 local) because of very strong industrial QRM (TV sets I think). I wonder also does DCF39 radiate all the time or part of time only? 73 de RA9MB/Alex http://www.qsl.net/ra9mb
