5970 kHz BBC WS Rampisham

Not good here, much AM interference from -5, 0, and +5 kHz.

This new frequency seems to be a bad choice, results even worse here, strong AM co-channel interferer (French language), also some interference from the adjacent channels.

Very bad frequency planning! Very strong signal but a stronger AM Co-channel interferer.

Strong AM signal, nearly no audio decoding, most of the time not even sync

Better forget about this frequency. It's a waste of transmitter power due to very strong co-channel interference as well as from other stations 5 kHz up and below.

Thanks for all the reports - this frequency does not look too good does it? I will ask our frequency planning guys to see if we can do anything. - If anyone does manage to identify the french language AM broadcaster please let me know. I had one e mail saying possibly CRI, but its useful to know for sure.

Hi James,
the co-channel station is CRI with 150 kW from Albania.
See coverage map.

Hi James,
the co-channel AM station could be clearly identified as CRI, bad results again in the last hour from Rampisham, here is a long log from Rampisham today including this frequency and a screenshot from the G313 showing the strong AM signal.

A catastrophic failure with strong AM signals all over, especially one from CRI right on channel.

Distance in the log is wrong.

...and here is an AM MP3 recording made at 10 kHz receiver IF bandwidth that further demonstrates the mess.

My best results on this frequency so far with 85% correctly decoded audio!

After somewhat better results yesterday, not much today. Seems not worth to continue on this frequency.
