Many thanks Mike for the information. I have been doing some checks today and it looks like there are two possibilities,in fact both combine to give the poor result. 1)My recieving loop has a deep nu
Many thanks Mike for the report,sorry I did'nt hear you ! If there is something wrong with my Rx side on 73, I dont think I know what it is Hi. Of course this points out the problems for anyone tryin
Hi All, Was there any 73KHz activity this morning? I monitored 71.6 to 72.1 from 0600 until 0800 UTC nothing heard or seen. Also put out several CQ calls. I can't guarantee my reciever or ant. at thi
Ok John,sorry you did'nt get set-up at the cottage. We might have made it friday night but as Alan says the nights are so short at the moment that the Ionosphere hardly has time to recover from dayti
Hi All, Well as it turned out it was not good timing! Alan reported the Kp index up to 4, still I went ahead and Brian reported seeing the signal,although it was not brilliant. I need a source of mor
Hi All, The Kp index is very low at present so I will run the 73KHz Beacon tonight. Starting at 2300 UTC on 71,921.5KHz. I will try DFCW with 60sec. dots.The power with the Decca is about 250mW so sh
Hi All, I ran the Beacon last night from 2330 to 0530 with no problems these Deccas run amazingly cool. Condx fairly good so will try again tonight, same time same freq. 73s Laurie.
Hi All, Peter G3LDO has kindly lent me his Decca Tx which I have re-modified back to 73KHz. No more power than before but much more reliable! So propose to run some beacon tests this weekend starting
Larrys signal appeared at about 0300 ,peaked briefly to "O" at 0400 and faded out by 0530UTC. Nice to see you again Larry ,guess condx were far from good last night.73s Laurie.
Hi John, There was a very strong signal above me but it was quite close to a Loran line from eastern France on 137.746 which my Ant. does not null out. If this was you sorry for missing you. Will try
Hi John and Steve, Many thanks for listening sorry nothing heard. Weather pretty stormy here tonight so will give it a miss. Will try again when conditions improve. Did anyone hear G0UPU on 136 this
Hi David and all. Peter G3LDO has leant me his Decca for a few weeks and I have re-modified it for 73KHz.This mod. uses additional coils which slide into the existing ones so enabling fine adjustment
Many thanks to everyone interested in more tests this winter, Jon W1HJ and John W1TAG have expressed an intrest. I propose to kick off with a bit of 73KHz beaconing before Alans predicted disturbance
Alan Melia sent me a message today asking wether anyone intended any T/A activity this year. We are already past the time when last year the first crossings were made. I would like to improve on my 7
I have given many antenna lectures inthe past and always the first stumbling block has been "how does it radiate". I did not fully understand the mechanism and none of the available analogies such as
Jim and Bob,very interested in your measurments and pleased that you have managed to fit some real theory to my empirical results (footprints etc). I wonder now wether there is a "law of diminishing
