10m FT8

After a few minutes on TX, I am now on 10m FT8 RX. No spots as yet.

UPDATE 1042z: Best DX spotted so far on 10m FT8 is OZ1LXJ (805km).

UPDATE 1355z: Just one more G station spotted on 10m FT8 today so far. Very quiet.

UPDATE 1603z: Just one more G and PG0DX (411km) spotted. These could be aircraft reflections.

UPDATE 2000z: No further spots today.

Sunspots - Sunday January 14th 2018

Solar flux is 70 today and the sunspot number remains at zero. A=7 and K=4.

Transatlantic on 472kHz

Last night, with the shack PC on battery power I copied 20 uniques, which is a record with my unbelievably bad antenna and ground. Honestly, you would be hard pushed to make you antenna any worse! The FT817 is also starting to get deaf at 472kHz (630m).

So, I was very pleased to spot N1BUG (4940km) twice last night in the early hours. This is the first time I have spotted any North Americans here at this QTH on WSPR on MF. Believe me, if I can spot across the Atlantic with my setup so can you!

New EbNaut decoder for VLF amateur DX

Paul Nicholson, a very good UK VLF SWL, has created some new software:

"Updated EbNaut decoder for Windows, now at version 0.8

 http://abelian.org/ebnaut/software_ms.shtml

This version does 16K23A which is a useful polynomial
for short messages combined with a large CRC.

The Linux program is up to version 0.9 now.

 http://abelian.org/ebnaut/software_linux.shtml

The only significant change is the use of DSW re-balancing
of the list decoder stack.  This may reduce decode time
a little when using very large list lengths.  It is most
useful when measuring the distance spectrum of a polynomial
where a degenerate tree often develops.

Back to 630m WSPR RX

At about 2130z I returned to 630m WSPR RX with the shack PC on internal battery power so the noise floor is lower. Already 5 unique stations spotted including ON7ZO (355km) who I am sure is new.

UPDATE 2210z: Now 10 unique stations including another new one for me - EA3AER (1142km).

Moles - NOT amateur radio

In the UK we get moles. These are small, furry animals that spend most of their time underground. They eat mainly worms.

You rarely see them but they have a nasty habit of leaving "mole hills" at regular intervals, often in well-kept lawns. They are otherwise harmless, but these mole hills can be a darn nuisance.

We saw these earlier today, but luckily not in our lawns!

10m FT8 RX

Yesterday I think I was on 10m FT8 but with the wrong antenna. Today I double checked! Quite a lot of Europeans spotted already on 10m.

UPDATE 1612z: 12 unique stations spotted so far today in 5 European countries on 10m FT8.

UPDATE 1727z: So far,17 uniques in 7 countries.

UPDATE 2123z: As well as lots of Europeans VP8LP (12772km) was spotted at 1751z. This is the first non-European spotted here on 10m FT8 this year, although my 10m antenna is very average.

630m WSPR RX last night

Turning off the mains to my shack laptop definitely helps reduce my 630m noise floor. Last night 16 unique stations were spotted, which is a record for me.

Winter - NOT amateur radio

At this time of year everything looks dead. In a few months we will have returning swallows, lambs, fresh green leaves and life. In reality, life is already stirring, but largely unseen.

Sunspots - Saturday January 13th 2018

Solar flux is 69 today and the sunspot number zero. A=4 and K=1.
