To all LF, Please beware that the official Dutch Telecom Agency has not yet published the issue of experimental licences for the 600m band tot the Dutch Amateur Radio organisations VERON and / or VRZ
Hi LF Radio Caroline is now on 531Kc/s from the MV Ross Revenge at the port of Tilbury in Essex. Signal RS 57-9 here in North Herts (UK). HNY 73 es GL petefmt
Hi LF Group <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> In an attempt to calculating the effect of ICE (Haw frost) on my antenna I get these results. With a wire diam
Well done Mal I heard PA0A the other night while you and UEP were CQing. I should have called him but because of the warning I sat it out. He probably would not have heard me any way. Too bad, I will
Too glib I can visualise the whisker pointing in the direction of time but not the mirror image how does that work. Please explain? How can the spread of sideband frequencies colapse onto the start e
Tnx Kees Last time I looked they had 60m not 600m but now they have MF. That Irish harmonic shows up clearly on it.... some power where it shouldn't be ..eh? I have used the 80m display to monitor a
Thanks for the info Mal My wire is flexweave, the un-insulated type. Last week I was impressed by the frost on the wire it made it look really fat. I did not actually measure the amount of frost but
Hi Mal and LF I think (from memory) all the stations you listed were outside the 501-504 apart from the PA station. And I am sure they were all fully licenced station within their own respective terr
OOOK I'll buy that. Lee points out the faint joining lines of constant frequency during period between expansion and contraction of the side bands. Indicating multi-frequency (harmonic) modulation at
Hi LF For those who don't yet know all the WSPR reception reports by suitably equiped stations are logged on a DATABASE. This is almost real time and can be filtered for BAND (say 500kc/s) and other
Hi Roger and LF 1/ 10Mhz is a totally different situation to the 500kc/s allocation and can not be compared. Its like comparing Apples and Bananas. It's a wide band compared to 500 and has very short
Good point Andy My method on 30m is to use a $30 Softrock T/RX and use an VAC (Virtual Audio Cable) to interconnect Joes software to my SDR application audio input and visa versa for the RX. Still li
Probably simpler to to make up a transverter - mixer with a xtal controlled oscillator and a few stages of linear amplification driving the mixer with an SSB rig. The whole thing about WSPR is the Lo
Yes Graham the German station is winning here at times but earlier RC was in the clear. There is more sky wave as evening comes on so I guess it's to be expected. They are running very low power but
Hi Group As an indication of what can be heard using a Sound Card RX, SAQ when on, is very strong with me using just an Inv Vee 80m dipole strapped feeder. Russian Alpha stations 10 to 15 kc/s tend t
Ken. Why not just stick an antenna wire into your Sound card mic socket and install either Argo Spectran or Spec lab FFT application. You then have DC to 48kc/s VLF coverage with the ability to detec
Well done Roger What happens with hard of hearing audio induction loops, they are every where nowadays? Does this mean if we put a an OFW305 they will issue us with an NOV? I am typing mine now! Than
Alan, Rik and Stefan Thank you for the practical solutions...... I am reading up on the earth conduction work done by John Taylor it may be possible for me to adapt some of his methods for this locat
