Dear MFers I made a capacity-hat portable vertical yesterday. I would have gone out to test it except the band was covered in static crashes. It occurred to me that they might not be that far away so
Dear all I am hoping to be granted an NoV for portable operating on 500kHz. I have parts on order for the GW3UEP Economy transmitter which will be run on 12 Volts. Suggestions for portable aerials th
I heard someone beaconing on 501.1kHz at 2030 local tonight. Just too weak to make out the call. Got "test" and QSK before they stopped. My beacon is on 501.8 now. Any recommended transverter designs
Seeing some weak traces on 503 kHz, it may be ON7WP ?? G I too can see a signal on 503kHz - not audible yet but clearly visible on the FFT. 73 Richard IO83wg
I wonder if anyone has attempted to plot the diurnal noise levels on 500kHz? I wonder if, for instance, very early on a Sunday morning is particularly quiet? 73 Richard G3CWI
Hi Alan Thanks for the analysis. I was actually thinking more of locally generated electrical noise - hence the reference to Sundays. I recall doing some test with Peter G3PLX years ago. We conducted
ON7WP QRS signal last night at 2135utc. At 2130 ON7WP was 549. OR7T was 419. GW3UEP also 419. Gus (SM? I forget his call) was 569. I called many times but my TX will only QSY to 502.5 so could not ne
Thanks for the reports on the beacon signal. If nothing else, it is at least a viable 500kHz TX antenna - as well as the reports, it is showing up reasonably well on the G3YXM and G4WGT grabbers. I h
Over the last few days I have been doing some experiments with ground systems with my LF/MF antenna. Jim Thank you for your detailed and well thought out review of earthing - the experimental results
