A miscellaneous post

ckThe team at VK9CZ spent the first few days on phone and then migrated to CW, becoming DXCC #302 (#299 with the dipole) for me soon thereafter.

Despite their posting about the lack of a reliable internet connection, I and many others had our LoTW confirmations only hours later.

That’s good because their signal was so strong that the thought crossed my mind that I’d worked a pirate although there was that tell-tale flutter.

It is currently 7:30 pm US East Coast local time and they are being received on the East Coast – on 80 meters! Normally those W4’s would be hearing Europe and Africa on 80m at that time…but VK9?! Strange propagation. Not a peep here on 80m…


If you’ve just started (or are thinking about) dabbling in antenna modeling and don’t have the book I recently mentioned, check out this site for a near-equivalent substitute.


And if you’ve already read my ‘Drone for everyman’ post, you may be interested in a couple of links left in the comments section by Charlie WA2ONH.

Keep in mind as you watch that no one is controlling these mini-drones with an R/C transmitter nor are they GPS-driven – they are completely autonomous.

Amazing stuff from the University of Pennsylvania. Thanks for the links, Charlie.


wxMy Davis VantageVue weather station has been mounted about three feet from the driven element of my Yagi for about three months now. It’s been exposed to a kilowatt on 14, 18, 21, 24 and 28 MHz and hasn’t missed a beat.

No resets needed and no missed reports to my indoor unit through walls and a ceiling 150 feet away.

Once these personal weather stations send their data out to the “cloud” they are assessed and given a grade based on accuracy. I don’t know how all that works or how accuracy is determined, but here are the results.

I’m just glad it’s “RF-hardened”.

    Congratulations, John. I have listened for them nightly as the sun goes down and I can just barely copy them, not good enough to confirm a QSO, so I haven’t called. I’m away tonight, figures it might be the best chance so far! Maybe it’s a sign that prop will be good the next few days? Sure hope so.

      Ed, I’ve attempted to work them on 3 bands – all three have been at times I wouldn’t have expected to be able to hear them. Looking at their stats on Clublog, I see that most of their contacts with the US on 40m occurred at 0000Z. Openings to them on 12, and 15 meters are occurring during our (US) mornings. Odd.

      Good luck to you.
