RFI 3965 kHz reception via KiwiSDR Web in Carlow, Ireland
The Carlow, SE Ireland, partial reception log of the 1 KW 3965 kHz RFI transmission via the KiwiSDR receiver on the web.
This particular RX web site limits the reception to only 15 minutes - the resyncs are probably due to external sound card/internet sources and not signal related. Interesting that the co-channel frequency of 3955 kHz had the Woofferton based transmission of Radio Taiwan International, and this did not appear to cause any reception problems.

RFI 3965 via Kiwi SDR in England
not bad around 1730, I have to try this one again. Good signal on peaks, but very deep fades.

RFI 3965 kHz reception via KiwiSDR Web near Tiddische, Germany
A little over half an hour of reception in Germany during the middle of the night. The signal was peaking to S9 +10db and dropping down to S8.
When decoding the audio quality was great.

TDF 3965 kHz Issoudun reception near Atlanta, Georgia, USA
The 1KW signal from Issoudun has been trying to get through in the last few days. This morning's received waveform looks much the same as it did in Message #588 (this thread) and although this log is much lighter than a previous one in Message #600 there is one SNR peak of 7.34 dB.
A short description of the TDF system is given in Message #610.

The 3965 kHz signal and Screen ID was showing up on KiwiSDR web receivers along the east coast USA last night as far south as North Carolina.

RFI 3965 kHz Issoudun reception near Atlanta, Georgia, USA
The overnight reception (until 0558 UTC) - no audio decoded, about 6 dB max SNR (the value shown in box in log is spurious). Not enough signal to show the Screen ID.

RFI Missing?
Anyone hearing RFI on 3965.0 kHz at the moment?
Usually I can hear it here without any problems after dark, and even if I can't decode it I can usually see the trace on my waterfall display, but no sign of it at all at present, the channel looks to be empty. Anyone know if it's off the air for some reason?
