I wonder if anyone on the list has experienced or has any knowledge of interference caused by the Grid Tie Inverters used in Solar PV farms? There is a proposal for a 4.4MW Solar PV farm about one mi
Hello Gary, Peter and all It's a good signal down here in Lincolnshire. It is a bit stronger on my E/W loop than my N/S loop and coupled with your location, I'd take an educated guess at the north-we
I think that it's because their Customs procedures are so irksome? I have a friend in the US who ships items over for me and he complains about all the paperwork that he has to complete. 73s Tracey H

Hello Clemens NDBs are generally modulated with either 1020Hz or 400Hz. In the frequency range concerned there is a mix, but it is predominantly 1020Hz You can see what has been received and their de

Hello Ken I doubt it, but you never know. I've just checked our Received In Europe (REU) database and there are some 29 inactive NDBs listed in the 472-479kHz range. If they were all to become active

Hello Mal You don't quote the all important, the bandwidth that you were taking these measurements in. I've just done a quick look on my receiver. 20kHz DDC bandwidth and 10Hz selectivity Noise floor
Hello mal That's from Darlowo in Poland, a military airfield I believe and the NDB is activated when required. It's just over 700 miles from me and is always a good signal. 73s Tracey -- Original Mes
