6m FT8 and "super DX"

It is now almost the end of May and I have still to catch "super DX" on 6m FT8. My system allowed me to catch a lot of great 6m DX on JT65 last year. I continue to watch in hope.

The system was turned on before breakfast. A quick 6m FT8 CQ (2.5W) brought spots from as far as Italy by Es, as well as Gs. Since then, I have been on 6m FT8 RX only.

UPDATE 0840z: So far 12 different stations spotted today in 3 countries.

UPDATE 1028z: 21 stations in 5 countries so far on 6m FT8 RX.

UPDATE 1540z: Now 30 stations in 5 countries on 6m FT8 RX today so far.

UPDATE 1814: Best DX on 6m FT8 RX is now 4X4DK (3580km). 5B4AIF (3193km) is the first station I have ever spotted on Cyprus on 6m. Also on again is S01WS (3043km) in Western Sahara.

UPDATE 1855z: Now 28 countries (I think) spotted in 3 continents so far today on 6m FT8. I have lost count of the number of stations, but there have been lots!

UPDATE 2110z:  QRT.

Friedrichshafen, Germany

This big European rally is fast approaching. Outside of the USA, I think this is the biggest amateur radio showcase in the world. Dates are June 1st-3rd 2018. Like Dayton, this is a chance for the big players to showcase new radios.

Sunspots - Saturday May 26th 2018

FT8 versus JT65

In the last few months the usage of FT8 is phenomenal. It uses about a third the bandwidth (about 50Hz) of JT65 and a much shorter TX period. In many ways it is an ideal QRP mode, especially in Es conditions.

I think FT8 is not as good as JT65 in terms of very weak signals, but I am no expert. So far, I have not spotted what I would call real DX on 6m, whereas last season I copied lots on 6m JT65. Now, this may be just conditions, so I need a few more months to decide.

It would be interesting to know how serious DXers find FT8. I only use a V2000 vertical, so others probably do better than me. As you know I'm a fair weather DXer. I do not chase DX, but I observe 6m FT8 most days.

FT8 is not a mode for chats. Without auto-sequencing enabled there is very little reaction time. It is a good mode for quick, formulaic exchanges.

See http://www.dx.nl/?p=860
This seems to show FT8 is some 6dB worse than JT65 on weak signals. Maybe this accounts for why I am spotting less real DX? Now, since then FT8 has been improved. Certainly, I shall stick with 6m FT8 this season to see what is spotted.

Our local museum - NOT amateur radio

YouTube posts - NOT all amateur radio!

A reminder that not all videos on my YouTube channel are amateur radio related.

Hamnet growing

According to a report on Southgate News, the Hamnet amateur network, mostly in Germany, is growing.

Old Cars - NOT amateur radio

Just over a week ago we attended a funeral in Nottingham and stayed in nearby Southwell.

The owners of these old cars were also staying in our hotel.

Lightning in Europe

At the moment, the lightning is in mainland Europe with nothing shown here in the UK on the lightning maps. I guess the storms over northern France could be an issue in southern counties of the UK later.  Definitely worth a look in a few hours time.
