Re: Topband: Bottom End Beacons
Here are two views of this Beacon on yesterday afternoon. The Beacon on almost every day. The upper one is coming from North East and the lower on from South East. http://kuvanjako.fi/wen9h.jpg http://kuvanjako.fi/vs7d2.jpg Working of DXs is normally Ok in the Beacon slots. 73!

Re: Topband: Bottom End Beacons
Yesterday evening they were S9 on my poor 6m high INV-L. The 1810-1820 interval is unusable here. 73 Ady YO2NAA On Tue, Feb 20, 2018 at 11:09 PM, Jean-Paul Albert via Topband < topband@contesting.com> wrote: > Yes Mark , around 6 pm GMT time louder than the days before. > Shorter propagation by the moment I suppose because no eastern station at > the grey line today. > > 73´ > Jean Paul > > > Envoyé de mon iPad > > > Le 20 févr. 2018 à 21:29, Mark van Wijk a écrit : > > > > And just tonight they are loud again: https://www.flickr.com/photos/ > pa5mw/39676032834/in/dateposted/ > > > > Signal level: 25dB above bandnoise > > > > RX antenna: 60mtr BOG in a ditch QTF 30 > > > > > > 73 > > Mark, PA5MW > > > > > >> On 2/20/2018 10:41 AM, Roger Kennedy wrote: > >> Yes, upon searching, I came across Alan Cordwell's web pages that he > wrote > >> about the old Decca HiFix navigation beacons that used to be VERY strong > >> here in Britain, but closed down during the 90s. > >> > >> I emailed him about these, as they sound very similar. > >> > >> He confirmed that they are a Russian system that works in much the same > way, > >> and have low power transmitter around the Baltic. > >> > >> As Mark posted, here's a link to Alan's webpage which shows you how they > >> sound: > >> > >> http://alancordwell.co.uk/Legacy/radionavigation/russian/bras.html > >> > >> They are used by fishermen to pinpoint their position so they can locate > >> fish stocks - that's why I referred to them as fishing beacons. > >> > >> I'm amazed some of you can hear them in the US, as they're rarely very > >> strong here - typically between S2 and S9, but generally around S5. > >> > >> But the thing to remember is that there are about 15 of them spaced > evenly > >> between 1800 and 1820 kHz . . and they are quite wide.

Re: Topband: Bottom End Beacons
Yes Mark , around 6 pm GMT time louder than the days before. Shorter propagation by the moment I suppose because no eastern station at the grey line today. 73´ Jean Paul Envoyé de mon iPad > Le 20 févr. 2018 à 21:29, Mark van Wijk a écrit : > > And just tonight they are loud again: > https://www.flickr.com/photos/pa5mw/39676032834/in/dateposted/ > > Signal level: 25dB above bandnoise > > RX antenna: 60mtr BOG in a ditch QTF 30 > > > 73 > Mark, PA5MW > > >> On 2/20/2018 10:41 AM, Roger Kennedy wrote: >> Yes, upon searching, I came across Alan Cordwell's web pages that he wrote >> about the old Decca HiFix navigation beacons that used to be VERY strong >> here in Britain, but closed down during the 90s. >> >> I emailed him about these, as they sound very similar. >> >> He confirmed that they are a Russian system that works in much the same way, >> and have low power transmitter around the Baltic. >> >> As Mark posted, here's a link to Alan's webpage which shows you how they >> sound: >> >> http://alancordwell.co.uk/Legacy/radionavigation/russian/bras.html >> >> They are used by fishermen to pinpoint their position so they can locate >> fish stocks - that's why I referred to them as fishing beacons. >> >> I'm amazed some of you can hear them in the US, as they're rarely very >> strong here - typically between S2 and S9, but generally around S5. >> >> But the thing to remember is that there are about 15 of them spaced evenly >> between 1800 and 1820 kHz . . and they are quite wide.

Topband: Bottom End Beacons
Yes, upon searching, I came across Alan Cordwell's web pages that he wrote about the old Decca HiFix navigation beacons that used to be VERY strong here in Britain, but closed down during the 90s. I emailed him about these, as they sound very similar. He confirmed that they are a Russian system that works in much the same way, and have low power transmitter around the Baltic. As Mark posted, here's a link to Alan's webpage which shows you how they sound: http://alancordwell.co.uk/Legacy/radionavigation/russian/bras.html They are used by fishermen to pinpoint their position so they can locate fish stocks - that's why I referred to them as fishing beacons. I'm amazed some of you can hear them in the US, as they're rarely very strong here - typically between S2 and S9, but generally around S5. But the thing to remember is that there are about 15 of them spaced evenly between 1800 and 1820 kHz . . and they are quite wide. So these will often block out weak DX signals here in Europe. So worth avoiding that part of the band. Hopefully they will turn them off soon, and just use GPS ! 73 Roger G3YRO _ Topband Reflector Archives - http://www.contesting.com/_topband
