Dahlias at Anglesey Abbey - NOT amateur radio

Usually there are good displays of dahlias at Anglesey Abbey. This year they are not quite at their best. In another week or so they will be. The photo shows one earlier today.

Anglesey Abbey - NOT amateur radio

This is a nearby National Trust place we try to visit most months for a walk around the gardens. At this time of year schools are on holiday and it can be quite busy. We went early before the hoards arrived! The bridge in the photo was recently repaired by one of our neighbours.

70cm FT8

After a brief outing on 6m FT8, I am now on 70cm FT8. At first I called CQ (no spots) and am now RX only. I am on 432.174MHz horizontal with the big-wheel 2m omni which normally gets me 100km on SSB in contests.

UPDATE 1112z: Success!! G0KTN (211km) managed to spot me on 70cm FT8. This was success at first try! Thank you Trevor. On horizontal using the 2m big-wheel omni, where the match was not so good, I could only run 14W. Trevor copied me on this. A later transmission with the V2000 vertical (good match) was at 50W but got no spots. I am now back on 6m FT8.

Sunspots - Thursday August 1st 2019

August already!

Solar flux is 66 and the sunspot number 0.  A= 8 and K=1.

Updated solar data

Early in the new month I look forward to reading the latest solar predictions. These are usually available by the 2nd of each month. With the solar conditions so dire in July, these are especially important as, until now they have forecast that we have passed the solar minimum.

In my view we are only now at, or near, the solar minimum. In the past, solar minimum conditions have lasted for many months. With luck, 2020 could see conditions start to improve, but only time will tell. In the meantime, we have to make the best of things. With luck, 10m could again be our best DX band again in a few years.

UPDATED 1855z: This page (see below) has now been updated and is still showing that we may have passed sunspot minimum.

G3XBM YouTube channel

A reminder that many of my projects are featured on my YouTube channel. Often a video helps to explain what is on the G3XBM website.

472kHz transverter

A few years ago my design for a simple 472kHz transverter was published in the ARRL journal QST. It is also on my website. Several derivatives have been constructed including a version using SMD parts.

Although simple and low power, it has been copied as far north as Norway on WSPR. Although the transverter produces 10-15W output, the ERP from the earth-electrode "antenna" is a measured 10mW.

Now is the time to get ready for "the season" which tends to start in the autumn. In the summer months quite a few stations desert the band. This transverter and a simple earth-electrode "antenna" in the ground are all that are needed to get on the band.

Certainly with more power and a "real" antenna and ground system better results can be expected, but this "KISS" approach you can get over 1000km on WSPR on winter nights.

2m FT8

As the day draws to a close, I decided to QSY to 2m FT8. Best DX on TX was GI6ATZ (479km).

UPDATE  2025z: Despite TXing OK on 2m FT8 I was puzzled why nothing was being received. After investigating I found an error in my settings. Once corrected, stations were received OK. I called (without success) a PA0, but the best spot was by EI3KD (583km) in southern Eire.

3 year old falls from high-rise and survives

This is the sort of horror story you watch and hope. Apparently the 3 year old was caught in a blanket and escaped without injury.
