Hi all, Thanks for private and reflector reports. It looks like reception in North America was very good at times. I'm working through confirmations from John W1TAG, Dex W4DEX, Mike KB6WFC and Mitch

Hi all, ZL6QH will be sending LF beacon transmissions overnight (New Zealand time) on 27, 28 and 29 December. Transmission will start about 0720 UTC (ZL6QH sunset is nominally 0752 UTC) and end about

Dick PA0SE, It was not until recently that I found out about the extent of "mixer control" placement(s) in a sound card. There are analogue and digital mixers. The MIC-IN, LINE-IN and CD-IN have inpu

Jim and others, I also find that external effects affect the depth of null you get - in my field strength measuring experiments, I found some locations where there was almost no null - This seemed to

Alan G3NYK, OK on the notch filter design, but for a high impedance load. I have often wanted to try a notch filter in a low impedance feeder, for such purposes as reducing a TV line oscillator harmo

Jim and others, Thanks for getting the numbers straightened out. I've been hasty with email recently due to "not enough minutes in the day". The mains harmonic situation is that "very high" frequency

Hi all, I made a numerical mistake in my last posting. 25 Hz shift at 136 kHz is a ratio of about 0.009, or 0.9%. Of course, we would like the "QRM deviation" of 50 Hz lines to be much less than plus

Hi Jim, Alberto, Rik and others, I agree that the frequency stability of the mains network is a point to consider further. However, I think there are two interference mechanisms at play in the LF ban

Hi all, I originally thought that 137.7000 kHz was clear of QRM in this corner of the world, however lots of capture time on trying to find a UA9OC signal (with success on 13 March) found a weak QRM

Hi all, Our experience at ZL6QH over the last two nights has lead us to consider that 60 second dot length is about right for long haul QSO attempts, as when propagation lifts even shorter dot length
