Hello Petr and all OMs!
That is fine! Be lucky, you are 212km away :-)
I was briefly receiving on the new band as well. I listened to signals from NDB  "RP", "PT", "VIB",  "BIA" :  

477kHz    1018/1030    RP    Malacky/Kuchyna       SVK   JN88NL
475kHz    1014/1018    PT    Petrovskoye              RUS   LO01CR
480kHz    1020/1025    VIB   Viterbo                     ITA    JN62AK
474kHz    1031/1034    BIA   Rzeszow/Jasionka     POL    KO10BC

Well, despite my problem with huge  "RP" signal I am sure, that the band will be  usable for me. I am going to build a new beam antenna on my garden. Its minimum receiving must be direct to "RP", of course :-)   

73!

Hello all,
 
I am not so pesimistic, more exactly, I am a bit more lucky. I am abt 212 km away from RP.
I made a first reception test this Sunday. RP is the strongest signal on the band but it doesn’t bother much. Besides it I heard two more beacons. The band is more spacy and much calmer than 136kHz. Looking forward to the day it is crowded by HAM sigs.
 
Listen to recordings at:

Hello OMs!
I read all your comments about new HAM band, they were written in the last days. To tell the truth, to use this band  will be a problem for me and all HAMS in our region. There is a Slovak NDB beacon "RP" located right between 472 and 479kHz.
 
CALL : RP
FREQ: 477kHz
Modulation:    +/- 1060Hz side bands
QTH: Malacky/Kuchyna
QRA: JN88NL  
 
My QTH is only 37km far from the "RP". The beacon´s signal is constantly  at least +50dB up to noise (in fact +60dB in the modulation gaps). The carrier is not problem, but the worst thing is the wide strong noise during the transmission. It is about +25dB - see the picture. I made sure myself, that it was not a problem of my RX. The situation is the same, when an attenuator between antenna and RX is used.
 
I hope that "RP" will not be a problem for you as well!
