Thanks Peter for an excellent and well reasoned explanation of the key click problem.Far better than the near hysteria that there has been on this reflector. A small contribution to the discussion,if
Hi Marco, Signals first seen at 1900,but not identified.Now reading callsign from 2030 good "O" sig with slow fading.Will continue to monitor.73s Laurie. .
Hello again Marco, Your beacon signal faded out here at 0930 am. No trace all day, but re-appeared at 1700 very weak. Just about readable now at 1730.Intresting experiment,73s Laurie.
After a short appearance1700 1800 very weak the signal dissapeared until 2030 when it slowly increased in strength becoming a good"O" by 2100 and "OO" by 2200 with some QSB.However by 2300 it was ver
Hi Alan, Thanks for your mail,yes I did mean .064Hz, slip of the finger Hi.But I could also get a better looking signal with .125Hz and even at 0.25 but only "M". This morning (Sunday) he was very we
Bonjour Marc. Welcome to 137.Very nice pictures of your station.Look foreward to working you soon,but there may be some difficulty because of interferance from Loran station at Lessay,quite close bea
Hi Alan, Sorry to hear about the Bug! There was a coronal mass ejection(CME) on 30/4/00,but not expected to arrive until 02/03 May? also M-Class flare on 01/05/00.73s Laurie.
Hi All, Perhaps this is just too naive-but would it not be possible to put a resistor in series to swamp the Ant.system resistance so that changes in it have little or at least less effect on the cur
Hi Alan, Had contact with HB2ASB at 10:05(start) on 14/5/00 so guess report from IK1HSS was me.Have not had contact with "I" yet so nice to know sig getting that far.Thanks 73s Laurie.
Hi James, Great that you are going to do some real comparitive tests.I think that this will be very useful. I hope that as many as possible will join in so that radiation at various distances can be
Hi Peter, Further to your request for info/experience with recievers ,I have tried several.The station here includes a 4 section BP filter(PA0SE design)modified for 137.I hope that this keeps big sig
Further to my previous note I forgot to mention that the 781 tunes in 10Hz steps 2.5Khz per revolution of the knob wheras the 756 can be set to 1hz steps with 500 Hz per revolution! which is of cours
Hi Jim and all, Thanks for all the hard work on the Ant tests.I confirm that the small Ant 5db better than the big one when grounded.Possibly 6db better when big Ant resonant.Very small difference I
Sorry Mal,I cant agree that the small ant "is but a long wire etc" if this is meant to imply that it is anything other than a short 9m high vertical with top loading,which will have the same omni-dir
Wether a wire is "long" or not must be related to the wavelength.In the case of 136Khz, 50M certainly isnt long! My point however is that the "small ant" at Puckeridge can only be described as a vert
Hi All, I think that what we have here is re-inforcement at certain frequencies due to the proximity of reflecting surfaces at critical distances(similar to "eigentones produced in a room by the wall
I may have added to the confusion last night. I heard a M signal from VE1ZZ during his 0000-0010 slot and made a short transmission on136.505 about 10Hz above Peter. Perhaps this was seen as instabil
