OV140 German SDR project

This started from the mcHF project and is an open source software and hardware project from Germany. When it is ready, it should be a very interesting SDR transceiver covering up to 2m with 75W. It is expected to be low cost.

10m FT8 good so far

My 10m (500mW) WSPR beacon seems to be doing a good job so far today. Yet again EA8BFK (2880km) is the best DX.

Sunspots - Friday June 29th 2018

Back to normal?

Solar flux is 69 and the sunspot number 0.  A=6 and K=2.

Japan-UK on 6m FT8

Although I have not spotted one yet, G stations were working Japan on 6m FT8 earlier. This very long path opens on 6m most seasons in June.

Personally, I think this is due to ionisation of the E layer due to noctilucent clouds and not multi-hop Es. If it was multi-hop it would happen at any time in the Es season. It only happens when noctilucent clouds are about.

UPDATE 1225z: WP4G (6803km) spotted on 6m FT8.

UPDATE  1331z: No 6m Es here currently - just Gs and near Europeans.

X80 vertical antenna

In the garage I have an SRC X80 multi-band HF vertical. I used this briefly (before my stroke) at the old QTH. It blows around in the wind, but worked quite well as I remember. With my LDG QRP ATU it might serve me well next winter on WSPR on several HF bands.

Verticals tend to be noisier than horizontal antennas. This is a Rybakov antenna fed via a transformer so they can be matched with an ATU more easily. If erected it would replace my horizontal antenna that only covers 3 HF bands.

This is now on my main website at www.g3xbm.co.uk . This was a "cut and paste" job ànd needs attention on the other PC in the morning as I see some words are not visible.

6m FT8 RX

Apparently Japan was being spotted and called on 6m FT8 earlier from southern Europe, although on my basic V2000 vertical omni system nothing was spotted here in the UK. Lots of Es received already. 45 countries spotted on 6m FT8 in the last day! 59 countries spotted in the last few days on 6m FT8 RX.
UPDATE 1354z: A brief CQ call on 6m FT8 QRP (2.5W) a few moments ago brought 2 QSOs (SP6 and EA3) as well as spots from stations all over Europe. I have gone back to 6m FT8 RX only.

10m WSPR TX

10m WSPR is good today. Already I have received 283 spots of my 500mW 10m WSPR beacon with the best DX being EA8BFK (2880km) and it is only 1036z.
UPDATE 1130z: Spotted by 11 different stations so far today on 10m WSPR.

UPDATE 1816z: My little WSPR beacon has been spotted by 23 different stations today.
