Re: LF: Band 472_479

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.

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!
