Dick, I haven't got AO so could you see what it says about the following: Walter G3JKV. Walter, I will send you the patterns (vertical polarisation, horizontal and vertical pattern) as attachments t
To All from PA0SE I have been playing around with feeding differently derived audio into the two halves of stereo headphones with some interesting results. I will report in detail when the tests are
Shouldn't you say "Computer simulations do not model this". Decca did a lot of measurements when they developed Navigator, and the physics always has the last word. The question should therefore be
Does anyone run the mechanical Hell' in this country? I think I once saw one in action many years ago. From memory the display was produced by a continously rotating helix which was brought into cont
To All from PAoSE In my e-mail of June 11 2000 9.39 I gave the URL of one of ZL1BPU's websites on which the history of the Hellschreiber can be found. When afterwards I tried to visit it there was no
Can anyone identify the issue(s) of Wireless World where it first appeared. It would be interesting to extract them from the archives and read up on just what was published Andy G4JNT The article app

Dear Peter, Many thanks for your fb service running the RSGB-LF-Group Reflector. It is just as important and useful as actual radio (wireless?) contacts on the LF-band. I wish you and yours a happy a
To All from PA0SE I tried to download EasyGram at several times during the day, evening, night and over the weekend. But the transmission was so awfully slow, sometimes nothing coming in during sever
To All from PA0SE Dave, G3YXM, writes in his LF column of RadCom of January 2001 that I measured the power of special event station MB2HFC at Old Windsor at about 750mW EIRP. That is not correct, it
To All from PA0SE Please see below the relevant definitions as they are recommended by the ITU. Many thanks Geri. Very useful info. 73, Dick, PA0SE "DEFINITIONS OF RADIATION IN LF, MF AND HF BROADCAS
To All from PA0SE May I inject an item on a low-tech subject into the stream of high-tech stuff that has been coming to us via the reflector? I know that soldering litz wire has been discussed extens
To M0BMU and All See your CQ clearly using spectogram. Don't know about O, M and all that jazz. Could also hear the signal but too weak for a QSO. Perhaps tomorrow morning when noise level is lower.
To All from PA0SE At roughly 2215 a carrier appeared at about 136.95, being keyed on and off intermittently (CFH station cat loose again?). Eventually it came on as a continuous carrier, and was fadi
To Allm from PA0SE i just had a look in the junkbox ... nothing arround these frequencies here. If you don't find the 10836 or 10564kHz xtals you might consider using a xtal on the 3rd overtone, that
To All from PA0SE Hans Peltzer, PA0HRP, drew my attention to an interesting web site: http://www.cpinternet.com/~lyle/models/lftxant.htm, featuring "Computer Modeling of LowFER Transmitting Antennas"
To All from PA0SE (and please keep in mind that "CW" means Carrier Wave, not "Morse"..) I thought CW means Continuous Wave. Am I wrong? 73, Dick, PA0SE
To All from PA0SE My plea for more normal CW activity on Saturday and Sunday morning had success. There was a healthy flow of traffic. Unfortunately later on Sunday morning reception was hampered by
To All from PA0SE I intend to measure the strength of normal CW signals received here on the mornings of Saturday 27 and Sunday 28 January. The results will come to you via the Reflector. 73, Dick, P
To All from PA0SE (...) However, the nature of radio itself is much more interesting; exploding PAs and trying to cross the Atlantic using bizzare communications modes is much more likely to attract
