If you are ready for receiving I would recommend to try to copy DCF39 on
138.830kHz. This commercial station runs about 30kW ERP and is located near
Magdeburg (Germany, JO52WG). It transmits a carrier that is interrupted by
a kind of 'RTTY burst' every 10 seconds.
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?
