mcHF transceiver

Some years ago the mcHF transceiver kit was launched by M0NKA. Since then it has been "cloned" and has been sold as the RS918. Whilst I think the design credit should go to M0NKA, I have some sympathy for those who did not want to buy the kit or were unable to build one.

This video is of the cloned radio. For the price it is good value. It is still sold. The original mcHF is also sold in the USA only as an assembled unit.

IC-705 video

There still seems to be a lot of rumour, but few facts, about the release of this new QRP radio from ICOM.  Many expect it to be on sale at Dayton in May, although I expect it will be released in Japan first. As for UK and EU release dates, I have no idea, although late 2020 is my guess. They have to obtain CE approval first. In the meantime, this video, which I think has been on before, might whet your appetite.

Orchids - NOT amateur radio

My wife seems to have a way with orchids! One on our windowsill has flowered since 2012!

20m FT8

About 20 minutes ago I went on 20m FT8 with the tiny indoor loop on the windowsill. Although plenty of RX spots (30 including Japan), nothing yet on TX. The power was only 6W and I may have landed on a frequency that has a strong carrier I could not see here. I have since increased the power a bit and QSYed about 200Hz HF to see if that does the trick.

UPDATE 1140z: Moving HF did the trick as I now have 16 spots on 20m FT8 TX.

UPDATE 1530z: Now 25 stations have spotted me. 

Amazing!
UPDATE 2133z: In total, 73 spots of my 10W to the tiny indoor loop. The map shows the stations spotting me on 20m FT8 today. Quite amazing.

Conspiracy theories - NOT amateur radio

This latest coronavirus seems to be something that naturally occurred and has worldwide impact but....

Have you thought that a hostile state could use biological warfare against its enemies?

Just imagine if research led to a bacterium or virus that was deadly to certain ethnic groups? A nation could cause an outbreak that could be hard to stop in certain peoples. This could be hard to target (for example there are lots of Chinese people in the USA and Australia).

Just like cyber warfare, such things could be very hard to prove, but could be very damaging.

All I am saying is the world is a very different place from 50 years ago.

Anemone blanda - NOT amateur radio

My wife took this photo yesterday. It shows an anemone blanda at nearby Anglesey Abbey.

Sunspots - Monday March 9th 2020 - sunspots back!

Earth-electrode "antenna" in the ground repair

Assuming it remains dry, I intend to fully replace the wire. A few weeks ago it broke and I suspect there may be breaks elsewhere. The wire has been there for over 6 years, so now is a good time to replace it. Some of the wire from the far ground runs just above the ground along the garden fence.

At the old QTH bringing this wire back to the house on the ground and using another ground close to the house (rather than the mains earth) seemed to make little difference at 472kHz. I think most radiation is from the loop formed in the ground. These findings seem to back this up.

UPDATE 1525z: As it has been raining I may have to wait until later this week.

20m FT8

A few minutes ago I went on 20m FT8 with the tiny indoor loop antenna. Already I have been spotted in Finland. On 20m FT8 RX 3 stations spotted so far today.

Although FT8 is still popular, I get the feeling this mode is going "off the boil" a bit.

UPDATE 1232z: I cannot believe how well this set-up works! Already 8 stations have spotted me with the best report of my 10W to the tiny indoor loop being K7BV (3897 miles). 27 stations in 3 continents spotted so far today.

UPDATE 1458z: So far today 22 spots of my 10W FT8 to the tiny indoor loop As there was a strong signal on my frequency I have QSYed HF about 100Hz. On RX 98 stations spotted so far today on 20m FT8 RX.

UPDATE 1842z : 31 spots of my 10W today and 205 stations spotted.

Iris - NOT amateur radio

We went for a nice walk at nearby Anglesey Abbey in the spring sunshine. Most snowdrops have now past their best but the daffodils are looking great. This iris was on the winter walk.
