At 1820-1830 UTC Saturday 15/7/17, I am receiving the Kuwait "DRM Service A" on 15540 here in Newfoundland.
I have both the MR27024 (with eight-metre outdoor wire) and the Avion DR-1401 (with Sony AN-LP1 active antenna attached) and neither one is getting as much as 10% decoding. They are both silent as I type and have been for two or three minutes. When the signal peaks, I hear (very good fidelity) sound for as much as ten seconds before it slips down again.
The Avion is showing MER levels ranging from 3dB to about 12 dB (audio decoding starts above that). The loop picks up the best signal when facing just east of North.
