161. Topband: Great Opening to Eu (score: 1)
Author: Greg - ZL3IX <zl3ix@inet.net.nz>

I enjoyed a really great opening to Eu around my SR this morning, with 15 in the log, from DL, PA, I, OK, F, and G. Wolf DF2PY peaked at a genuine 599, and I was still working guys 20-25 min after SR

Hi Paul, I would say that S9 is a little on the high side for a suburban environment. I also have a resonant antenna, and the background noise is about S5, or -97 dBm. Is your S-meter well calibrated

Hi Brian, I can see two main problems with doing this. I haven't tried using the actual fence strand, but I did have a Beverage that ran close along the top of the fence. Problem 1. Being in close pr

Hi Ken, Not quite sure to which arrangement you refer, but back in my days as ZS5K, I built a single wire 2-way Bev, using 2 lengths of coax. I did bias them though, and used the bias to feed a relay

Hi all, Ever since I first commissioned my remote receiving site in 2004, I have had issues with coax. At that stage, as I needed over 400m, I went for the cheapest 75 ohm that I could find, namely R

Hi Mike, Perhaps not quite what you were after, but I have found that the new DSP Rx at my remote 160m site works better than any analogue Rx I have had there. I am using a modified Mercury PCB from

Hi Mark, 250ft is VERY short for a TB Beverage. You will get some F/B, but the front lobe will be very broad. Can you extend it at all, maybe asking some kind neighbours to use a bit of their land? 5

Hi All, I'm sure that the Epsom salts trick works well, but seems to require quite a high level of maintenance. At my remote Rx site I use multiple ground rods to terminate my Beverages. I find that

Hi Pete, As long as your relays have decent isolation, even for high impedances, it may even be better to switch the Bev wires themselves. That way you don't share the ground at the feed end, and avo

In the discussion during the week, the common wisdom seemed to be that it was better to switch at the transformer secondary, ie the low impedance side. Well, I thought it rather surprising that the i

It seems wrong, and is wrong, Brendan. DXCC rules require the Rx antenna to be in the same country as the Tx antenna. Personally I think that there should also be a requirement that it is owned and m

Hi Eddy, I would say that activity has been fairly normal, but propagation has been above average, especially over the CQ 160 SSB test. My log book has far more entries in it than for any other year

Jeff, I suspect that you mean modern day synthesisers rather than specifically DDS. Actually, the DDS itself has quite low phase noise, better than -130 dBc/Hz with Analog Devices chips, especially i
