Dear all I thought I'd run the grabber on the US window to see how Rugby affects the region around 137.777 and it occurs to me that I can use the lines to calibrate my receiver exactly. Can anyone te
David and co I have made a recording this evening with a repeatable signal (about "S6") in the passband and will make another when the Loran is on. It'll be interesting to see if I can hear the S6 si
Gary That's strange. I would be happier with some 50A FETs, I rather like the IXYS IXFH58N20 but the ones you are using should be OK... I suppose the FETs are well clamped down with not too much heat
Gary. Have you any SWR protection on the TX? I would doubt if the cores would saturate so quickly that you didn't notice the heat and drop-off in power before it went pop! SWR protection is essential
Ingolf I sent a minute of carrier at 1722 and could see it very well on your grabber. My frequency was set at 137.777 but your grabber shows it as 137.776 I will check my calibration later. The clock
Dear all. Has anyone noticed this announcement at www.nels.org ? NOTICE CONCERNING LORAN-C IN NORTHWEST EUROPE The Northwest European Loran-C System (NELS) will be discontinued on 1 January 2006. How
Dear all. In the next Radcom LF column would like to do a piece about the effect of Rugby Loran on UK stations. How much interference is there at your QTH? How are you coping with the QRM? Etc. All i
Stewart How much of it would you like?! I can do you a wav file. I think I've got some "before" recordings too. Dave G3YXM --Original Message-- From: [email protected] [mailto:owner-
Dear all. I hear from Bill G0AKY (Via Steve GW4ALG) that his good friend Colin G3KMP died earlier this year whilst on holiday in Germany. Although he didn't make all that many QSOs on LF Colin was a
Dear all I'm a bit short of the LF news for the next column so if any of you have news of new developments at your station, new countries worked, modes tried, fets blown etc etc. please let me know.
Dear all Due to the unreliability of BT Internet's FTP servers I have changed the picture URLs for the grabber. The main page remains the same at http://www.wireless.org.uk/grab/ and has been updated
Markus Interesting. The frequencies are right. I could understand the Rugby one because that's loud here but neither DCF39 nor Lessay are loud enough to intermod locally so where does that product ge
Dear all Following all the discussion of the "G3YXM design" filter, I feel I ought to let you in on the time consuming process I used to arrive at those values: Stage 1. Look up a topband PA design A
Dear all Myself and Gary G4WGT both see these fuzzy lines on Argo. I seem to remember some discussion of their origin before but can't remember whether there was a definite answer. The come in at dus
I ran a grabber on it but no decode. It looks like a good frequency here, nicely between Rugby lines so it may be worth another go. Others signals were fading in and out of the noise in about half-ho
That phase modulated data is a real pain. In the Scottish borders Droitwich beats with Westerglen (between Glasgow and Edinburgh) which either doesn't have phase mod data, or has different data on it

Joe I've recently been using a tuned rotatable loop antenna to receive DX and null out Rugby Loran and frankly it's poor, it picks up all the local noise going, the main antenna is much less noisy de
Gary Yes I think it was the loop because I can see the wobbly interference that it picks up. It's amazing how little ERP you need to get 100 miles or so, I did some tests with Alan Melia and I got do
