i would guess the latter, Andy, as 1580 is not evenly divisible by 9, so does not comply with the MW band plan.
1575kHz and 1584kHz are compliant channel frequencies and transmissions in either of these channels would cause an unwelcome beat. However, with many European countries closing down MW transmitters at an ever increasing rate there must be a fair number of gaps to accommodate such off-channel sources.
Long gone are the days when it was claimed that over 3,000 transmitters occupied 121 MW channels (120 since WARC 79).
