Re: LOTW help
I realised very quickly when I started actively DXing several years ago the advantage of electronic logbook and electronic QSL systems. A paper logbook of course can be managed, as it was from the beginning, but an electronic logbook will at the very least make tallying your award totals and keeping...

Re: Trans-Tasman Low-Bands Challenge 2016
Nice to work you John VK4BZ/2 on Top Band last night. You were unreadable on SSB, but quite workable on CW! I didn't operate "VHF", just 160 m, and it was nice to see some activity on the band.

Re: 40 meter rotatable dipole questions
FWIW Its not worth commenting on these pages because no one listens and everyone has their own opinion What are you on about Gregory? You appear to have no posts in this thread to ignore. As mentioned before, a vertical array may be worth considering. A "half square" will fit in your back...

Re: 40 meter rotatable dipole questions
The Bobtail Curtain performed very well. It certainly worked well broadside, compared to a large doublet antenna. Rubbish from the north (off the end) was noticeably attenuated. As Peter noted above, a 2 element broadside array, known as a Half Square works nearly as well. But as you already have a ...

Re: 40 meter rotatable dipole questions
A vertical monopole offers no rejection in any direction. A horizontal dipole can provide some rejection off the ends. Another antenna I experimented with was a vertical array - Bobtail Curtain. I oriented this to reject the crap to the north, and provide some gain in two directions in which I was i...

Re: 40 meter rotatable dipole questions
I support your proposal for a rotary dipole. Several years ago, I started noticing many DX stations using rotary dipoles with good results, surprisingly superior to their fixed wire dipoles. A few years ago, I knocked together a rotary dipole, and used two 7 metre telescopic fibreglass poles. I had ...

Re: The future for amateur radio in VK
I studied the ITU regulations regarding pX and pY and it comes down to a given average power for the different modes. CW has a roughly similar duty cycle to SSB, 25-40% or so. FM and most digital modes have a duty cycle of 100%. My argument is that the CW key-down power limit should be the same as t...

Re: Ted Powell (VK2AU) Memorial DX Challenge
Hi Peter, This a neat competition! I especially like the way the log uploader works. Very clever indeed. Let's have some more entries! Were there only six for the last quarter, or only the top six entrants listed in the results? I've been having a dream run the past six months or so, I hope others a...

Re: VK9NU - Norfolk Island
Oh yes, Anzac Day is commemorated with a Dawn Service at Emily Bay. This is the first Dawn Service in Australian Territory, being so far east. The Dawn Service is well-attended, and breakfast is served at the Administrator's residence in Quality Row a short walk from Emily Bay, this being all in the...

Re: VK9NU - Norfolk Island
There is almost no AR activity at all on NI apart from visitors. There are two residents who are licensed, but rarely on air. You might like to look up John VK9JA, he lives on Mission Hill Rd. You will probably find nobody to talk to on VHF/UHF, and there is certainly no repeater there. Internet is ...

Re: Solar Cycle #24 is (Doh) Crashing
I have been active through this cycle on Low Bands, and look forward to great conditions like we had in 2007,8 and 9.
I might even take down the 6 m beam and put up my 2 m beam again.

Re: HELL on Tuesday!
I like the actual human involvement with Feld Hell. WSPR, isn't that the mode you use when you are asleep? Good luck with VK0EK. They aren't hearing my 5 watts this evening on 15 m. Worked other bands though (with more than 5 watts). Re: VK0EK, look at this short video. It made me smile! https://www...

Re: HELL on Tuesday!
Perfect copy this evening on VK3IH, VK2PWR, VK2EIK and VK3FM using Feld Hell.
It's a cool mode, isn't it? It still requires eyes and brain to decode.

How about 30 m, which is an all digital and CW band?

Re: Waterproofing with self-fusing silicone tape
Yes, it's the best stuff for weather sealing connectors, etc.
I've had connectors out in the weather for ten years and found them as good as the day I wrapped them.
Self-fusing tape doesn't make a revolting sticky mess like PVC electrical tape.

Re: Anyone use Hellschreiber?
Sunday mornings are out for me, as I am nearly always out on my bike at that time. Late afternoon might be better for VK4-VK3 on 40 m. I'd like to make a few Hellschreiber QSO. Feld Hell is not strictly a digital mode, as it needs to be read from the screen like a ticker tape. This gives it a nice &...

Re: Anyone use Hellschreiber?
Paul, that's too early for me.
I am usually up around sunrise, 2020z working Top Band.
2100z or a bit later might suit, as the DX should be shutting down on 40 m by then.
