10m FT8 RX - Thursday, October 26th 2017

Well, there is little doubt that FT8 has transformed 10m. Looking at the map of spots for today on 10m, you could be excused for thinking this was sunspot maximum rather than way on the downward slope to the next minimum. Best DX today was VK8NSB (13800km) in Northern Territory, Australia.

OFCOM and spectrum at 3.6GHz

OFCOM has issued a statement about 3.6GHz spectrum.

Trinity College, Cambridge - NOT amateur radio

Living very close to Cambridge, it is very easy to take some wonderful places for granted. This is a picture of the entrance to Trinity College. There is a proctor in the photo complete with bowler hat (bottom left in the shadows). As a local we get free entry into the colleges, which some cross the world to see. With bus passes these are totally free. What a privilege.

630m transformer

When I moved to the "new" QTH 4 years ago I found I needed a step-up transformer to match my 630m transverter to the earth-electrode "antenna". For this I used my traditional method - try it and see what works.

An auto-transformer was wound on a 3C90 42mm toroid core (at least I think that is what it was). It worked and seems to give a decent match.

Of late, I have used the coax up to my 2m big-wheel antenna as a Marconi, tuned against ground with a ferrite rod ATU. So far, best DX is Norway (769km) with 31 unique spots of my 10mW ERP.

10m FT8

Amazing again!  Already loads of Europeans copied and 5 continents spotted on 10m FT8 RX when the sunspot count is low. FT8 - pure magic! This proves it is often a lack of activity rather than conditions on 10m. With FT8 all users are in a narrow slot, which helps.

UPDATE 1746z: 65 countries spotted in the last week on 10m FT8. No North Americans today so far.

10m FT8 RX today - dead?

UPDATE 2138z:  I've been on 630m WSPR for some hours now. When I left 10m FT8, there were still loads of South Americans coming through. And to think 10m is meant to be "dead".

Sunspots - Wednesday October 25th 2017

Solar flux is 77 today and the sunspot number is 23. A=18 and K=4.

Late night on 10m FT8 RX

For a change, I decided not to switch to 630m WSPR, but stick instead on 10m FT8 RX. I shall be on overnight, so that I am on very early in the morning. XE1XJB (8919km) in Mexico was spotted quite late.

10m FT8

So far today only 3 continents on 10m FT8. Best 10m FT8 DX, so far, is F5MYK/MM (9767km) near Mauritius.

UPDATE 1712z: With 16 unique stations spotted in North America today and loads in South America, today is again a great day on 10m FT8, proving that a lack of activity on 10m is often the problem rather than poor conditions.

Sunspots - Tuesday October 24th 2017

Solar flux is 77 today and the sunspot number is 23. A=6 and K=2.
