Re: LF: 160 to 190 KHz a real magic band ?

Graham,

Have a listen after dark, I seem to remember it was quite horrendous last time I looked at that part of the spectrum. I will have another listen tonight. I think the EU chaps wait until Europe1 has stopped Txing. Here is one frequency I know of, extract from Joe's e-mail.

VO1NA, 184.509.3kHz

TX about 5 watts 0.4 amps to 100m wire at 15 m high.

73,

Ok Gary,

 

Seems to  be  some quite big  gaps  in that  spectrum , big  enough  for a  cw filter and  wspr signal to  sit  with  no  splash ?

Nb looks like someone has the  spam  filter -mal-adjusted- ?

Graham,

I have occasionally read mails on LF regarding U.S. 184kHz qrs beacons & captures from Europe. Apparently there is a very powerful broadcast station in Europe on a near frequency which causes high qrm when on, I believe it is "Europe1"

1 watt and  15  mtrs  of antenna ,decoding  over  1148 kmtrs  , (best round 2000k)    seems  to  make the  137  attempts look a little 'coy  with  somewhat  bigger power levels and  rather  large  arrays , (possibly mal-adjusted ?)

 

Is this  a band  like 500  with  enhanced  propagation ?

 

WHAT IS THE  POSSIBILITY OF A  TA  DECODE ?

 

The frequency range is 160 to 190 KHz. This is most commonly known as Part-15 operation ( under our FCC Part-15 rules ). The basics: Power is limited to 1 Watt DC Input to the Final amplifier, and the antenna length cannot exceed 15 meters, including the feed line,

 

(XR4TN  is the experimental  call  of  KU4XR)
