More VLF experiments
Stefan DK7FC is planning more VLF tests at 17.47kHz:
"Hi VLF,
For this week, i'm planning to start with new experiments on 17.47 kHz,
where i have a (renewed) special permission to transmit.
So far the best results were a prooved carrier detection as well as a 1
character EbNaut decode by Edgar from Tasmania (VK7).
The first goal will be to determine the best time (start time and
length) on the path for this season. We have a usable path for about 2
months centered on our autun/spring time (21st SEP).
The Signal will be exported by SpecLab to simple txt files containing
the FFT data. This allows stacking, which will be required to get some
S/N at all. A reasonable stable path is essential during the
transmission time. All this will be determined by running some carrier
transmissions, a few hours per day, starting about 16 UTC.
When knowing the time to try we will attempt to transfer a 2 character
message and then even longer messages. 5 characters would be realistic i
think, with some luck and good propagation and low QRN on the RX site...
More soon.
73, Stefan"

New Monster Antenna
Southgate News has a piece today about a new dual-band monster antenna from Innovantennas for 4m and 2m. I think if I tried to erect this I would incur the wrath of the neighbours. Perhaps you live on a remote hillside and the nearest neighbour lives 2 miles away!

Llangollen Aqueduct - NOT amateur radio
This is an amazing piece of architecture designed by Thomas Telford centuries ago to take a canal high across a valley. Although there is a narrow path on one side the other side has a sheer drop! We were taken here today by our wedding "best man". That was 47 years ago! He lives on the Wirral near Liverpool. I was too giddy to walk across.

Catch 22 - NOT amateur radio
This book is always rated highly but I have yet to speak with anyone who has enjoyed it. I managed to get through it, but found it boring as hell. My wife has tried several times, but always given up! We gave away our copy (keep it PLEASE) and were only too glad to get rid of it. Maybe it means more if you are American and it was read years ago?
If you read it, I'd like to know how you got on.
I still find it hard to see why it is so highly rated.

Last month's 2m activity contest
Despite a logging error, I see my position in the AL section is unchanged. My error was stupid and cost me points, not that I take any contests seriously. My main aim is fun, to work a few stations and exercise my voice.

10m WSPR TX (500mW)
As usual, I am on 10m WSPR TX with my beacon. As yet, no spots.
UPDATE 1110z: Several Es spots. Best DX is CS7AOL (1457km).

Yet more on 60m band
The 60m WRC 15kHz allocation is being widely allocated now, with Finland (OH) joining the growing list. Sadly, the Finns are losing some other slots at 60m.
