Many thanks to G3PAI, G3GVB, M0BMU, LA8AK and PA0KDM (via direct e-mail) for their info on the regulations for top band. I now have sufficient info for my article in Electron. The current regulations
To All from PA0SE, Sorry to use the reflector for a non-lf topic but in this way I can reach many amateurs in the UK that can possibly help me with some info I require. I am presently writing an arti

Dear Bryan, Because the aerial system is very small, expressed in wavelength, the voltage on all wires "above" the loading coil will be the same; unless there is another loading coil between the vert
To All from PA0SE Further to my e-mail of 26 December I measured the field strength as radiated by the aerial in Inverted L-configuration. From this I found EMRP = 57 milliwatt. This confirms the ben
To Alan, Peter and Mal, Tnx for your comments. I have added my reply in red. Hi both, could I ask if the said insulator is fitted with an "anti-corona" ring. Severe changes in direction of the wire c
To All from PA0SE, The transmitter I use on LF was constructed by Harry Grimbergen, PA0LQ. It is a semiconductor affair but with 4 valves PL519 in parallel in the PA. At an input of 0.9A at 500V it p
To All from PA0SE, This morning I measured the field strength of my transmitter again, after improving the insulation at the feed-through of the aerial to the shack, using the centre conductor plus i
I am grateful to CT1DRP, DF6NM, DJ2LF, G3NYK, KL1X, M0BMU and W4DEX for comments and/or reports on my QRSS10 beaconing on 13/14 December. I did not span the Atlantic but will certainly have another t
Dear Walter, No reports yet except from you and Alan. But Alan reports that transatlantic propagation was poor, even CHF was very weak. When I started at 2200 UTC on Saturday frequency was 135.9225 k
To All from PA0SE Tnx to Alan and Jim for their comments. I intend to do so beaconing and as a compromise will use QRSS10. I will try to stick to 135.922kHz, the frequency K1LX is monitoring (hope th
To All from PA0SE The coming night 13/14 December I would like to try QRSS for the first time. The transmitter I use has been built and used by Harry, PA0LQ. Output power 300W, aerial current 3A. I h

To All from PA0SE The following message was sent before but I now have added a request. I intend to do beaconing tonight, starting around 2200 UTC and using QRSS30 on 135922Hz. Will stop about 0800 U
To All from PA0SE I intend to do beaconing tonight, starting around 2200 UTC and using QRSS30 on 135922Hz. Will stop about 0800 UTC on 30/1. Power about 140 milliwatt EMRP. 73, Dick, PA0SE

Dear John, Though the traces on the screen shots are not too clear I am convinced it is my signal, especially as the frequency tallies with Markus' measurement and there being no other participant on
Dear John, Computer simulation takes place over perfect ground and shows appreciable horizontally polarised radiation under high elevation angles for the inverted-L aerial . But even at say 20m heigh
