There must be a List somewhere of Electromagnetic Compatible electrical
appliances. I asked around at my Radio Club and Ham friends for
recommendations for a split-system a/c and a Solar Inverter. I often
hear of other radio amateurs whose enjoyment of the hobby is ruined by a
neighbour
We only use a solar powered clothes dryer, aka Hills Hoist. Never a
problem with RFI.

Rob, are you implying that I shouldn't use a steel lattice tower to
conduct RF as a radiator?
For coil taps, I like to solder.

You can also alter the resonance by changing the slope of the top hat
wires. If you can make them more horizontal, this will slightly lower
the resonant frequency. Either make them tighter or move the ends of the
supports further out. I have supports 3 m high, 40 m out from the
centre. My top
I listened yesterday evening through much of NA sunrise. I could see
there were many stations on, but few were loud enough to make it through
the storm QRN this end. After calling a few of the more readable
stations with no response, I went to bed. I heard VK3NX call and
eventually work AA6AA,
Yes, I too enjoy reading the posts, and am also missing DXpedition
activity. I'm at 143 countries and 34 Zones worked and confirmed, and am
always looking for new ones. I hear/see some Caribbean stations fairly
regularly, but no luck there recently. Of course, they are subject to

John OX/OZ1LXJ was a nice addition to the log yesterday evening around
0930z. He was not easy copy at the time, but good enough to call.
Despite his "Ugly QRN" we made the contact. I also had storm static
making it difficult, despite there being no significant thunderstorm
activity in my
Last night's conditions on the band were quite good. It was quiet this
end and I could hear many (US) stations calling the contest stations
here, and I worked a few myself. Unfortunately, I couldn't stick at it
as I have a very hard couple of days work. Hopefully conditions
continue, although
I rarely see CW activity much above 1830 kHz. The only issue I see from
time to time is SSB interference to the 1840 kHz FT8 channel.
VK band is 1800 - 1875 kHz. If a particular mode were moved above 1900
kHz, some here would miss out. We would have to do what JA FT8 ops did
until recently
Why don't you add one metre more to your pole?
I have Beverage antennas here, supported by 4 m treated pine poles. This
leaves 3 m above ground and one metre in the ground. This is barely high
enough for me to drive the tractor under the wires. Also, where the
Beverage wires cross the laneway
Sorry Tim, et al.

The band has been improving significantly in the past few weeks.
I have been working a few NA stations nearly every day all year, in
marginal to ok conditions.
Since the start of September, I've been typically working several DX
daily, mostly NA with a JA or two.
Yesterday, I ended up
I am planning a similar installation, using Deeco mast sections (6' x
10"). I have 20 of these, used of course. I don't think they have been
manufactured for decades. Sections interface with pin and socket, with 3
x 1/2" bolts between plates on each end.

Thanks for the heads-up.
I run Windows 10 on a newer Dell Optiplex with a solid state drive which
allows me a very fast start up of my HPSDR station running an older
version of PowerSDR console. I loaded the latest PowerSDR when I got the
machine, but it had issues, so I reverted to the older
Nice to hear you almost daily, Bob. Top Band is very slow during our
winter time. It's good to see some activity at all. Yesterday I also
worked AA1K and K3UL on the East Coast.
Len, 0200z is midday here. I am quite certain we won't work at that
time! I start to look for European stations as
I read somewhere that one test for a receiving antenna is to compare the
received noise floor against no antenna, during the day with little
atmospheric noise. There should be a *slight* lift in the noise when the
receive antenna is connected. This is as little as 2-3 dB at my QTH, a
