World Music Radio 15805 kHz

WMR is broadcasting on 15805 kHz (Sa/Su 07-20 UTC) in AM and so listeners (= DXers) are advised to listen in the AM mode. 

Glenn Hauser reports "wobbling unstable carrier tuning USB or LSB" and an "awful, unlistenable" signal and then questions whether I monitor the signal on 15805 kHz.  Of course I do, and that is why I repeatedly have asked DXers to utilise AM and not SSB when listening to WMR on 15805 kHz.

If I had all the money in the world (which I haven't and this is of course just an expensive hobby project) I could probably have the tx fixed so it provided good audio also using SSB, but - sorry - this just isn't a priority as long as 15805 kHz sounds ok in AM. And it does:

Judging coverage of SW stations by using remote KiwiSDRs is not fair.  It should be a well-known fact that most of these KiwiSDRs are connected to extremely inefficient aerials and often in environments with a lot of manmade interference. In other words completely useless.  However there a few good ones, and WMR can usually be heard quite well on these SDRs:
W-Greece: http://sdr.telcosol.gr:8073/
Sardinia, Italy: http://sibamanna.duckdns.org:8073/
Bucharest, Romania: http://kiwisdr.yo3iul.ro:8074/
And is also regularly heard on these SDR's - though of course with a much weaker signal:
Kuwait: http://9k2ra.proxy.kiwisdr.com:8073/  (mornings UTC)
NH, USA: http://w1nt.onthewifi.com:8073/ (afternoons UTC)
Brazil: http://appr.org.br:8073/ (afternoons UTC)
South Africa: http://kp.twrmon.net:8073/ (late afternoons UTC)

Btw: If everything goes well, WMR will be returning to 5840 kHz with a new and stronger transmitter (500 W) from a new transmitter site near Bramming within the next two weeks.  This will be on the air 24/7.
