160m FT8 RX

A few minutes ago I QSYed to 160m FT8 RX using the earth-electrode "antenna" in the ground. 57 stations spotted with UA9CGL (3793km) as best DX spotted so far this evening.

View from the London Eye - NOT amateur radio

Years ago we went with our sons and grandsons for a trip on the London Eye. This is the view west on a dull, wet day.

Flybe - NOT amateur radio

As I write there is a danger of Flybe collapsing. This airline is based in Devon and serves many airports around the UK and Europe. I hope this can be avoided.

2m FT8

A few moments ago I switched to 2m FT8. At first I called CQ (10W to the big-wheel omni) and now I am RX only. Best DX on TX was G7RAU (461km) in Cornwall. All the other spots of me (7) were by G stations. On 2m FT8 RX 3 stations in 2 countries spotted so far today.

UPDATE 1423z: 11 stations in 5 countries so far spotted today on 2m FT8 RX.

UPDATE 1751z : Now 21 stations spotted.
Stations spotted today on 2m FT8 RX 
UPDATE 2115z: About an hour ago I called CQ (10W) on 2m FT8. In all, 10 stations in 3 countries spotted me. On 2m FT8 RX 40 stations in 6 countries spotted so far today.

UPDATE 2144z: A recent FT8 CQ call on 2m was spotted by several stations including GI6ATZ (479km).

Hyacinths - NOT amateur radio

My wife was given a collection of hyacinths. These came out a few days ago and have given us much pleasure.

G3XBM shack and antennas

Just over a year ago I made a video showing the shack and antennas in use at that time. My voice is very poor!

Since then, I have made a few changes, but still mostly use FT8. There are other videos on the G3XBM channel, most made when my voice was OK!

WISPY

It is some years since I designed this TX. At the time I needed a quick and low cost way to TX WSPR on 10m.

I opted for a DSB TX using low cost 14.060MHz crystals and doubling. The PA used low cost transistors. These days many prefer FT8, although WSPR works with much lower signal levels.

You may find some useful ideas in the circuit even if you do not use it for WSPR. The site below also has a transceive option. This was breadboarded as separate RX and TX units but never tried as a full transceiver. It should work.

The same circuit (and the transceive option) should also work on PSK31. Just think of it: work the world for a few pounds!

Worst night yet on 160m FT8

Overnight 160m was the worst I can remember this season with just 9 North Americans spotted. Nothing from the Caribbean or South America. Again, using the earth-electrode "antenna" in the ground. A week ago I was spotting more than 50 North Americans on 160m FT8 RX nightly!

160m FT8

As it is dark, I have QSYed to 160m FT8. 104 stations spotted so far. Best DX so far this evening is RJ6J (3414km).

UPDATE 2220z: At the moment 225 stations spotted this evening on 160m FT8 RX. First North American was spotted at 2112z. This was VY2NA (4445km) on Prince Edward Island, Canada.
