Warmest place in the UK on Sunday - NOT amateur radio

Well, apparently Cambridge was the warmest place in the UK yesterday. Temperatures exceeded 25 dec C. Today it is still bright and sunny but much cooler.

Enjoying the sun - NOT amateur radio

We have had a decent few days with a high pressure system overhead. Today, temperatures reached 23- 24 deg C. Tomorrow it is likely to be much cooler and duller. We ate lunch in the garden for a change.

This blackbird was obviously enjoying the good weather. It stayed in this position for quite a while.

Sunspots and 10m - Sunday April 9th 2017

Solar flux is 73 today, but the sunspot number is zero again. A=16 and K=4.

WISPY WSPR beacon

Some time before my stroke in 2013, I designed a simple WSPR beacon for 10m that used low cost 14.060MHz QRP crystals doubled. These pulled up sufficiently.

This beacon was copied all across the globe. It uses a DSB transmitter, so the power goes out on two frequencies so the power in the WSPR slot is half. With the Es season approaching you may like to build it. 10m should be fun May-September in the Northern Hemisphere.

The PA could be replaced by paralleled 2N3904s instead of the 2N3866 to get more power for a few pence. 2N3904s are very very cheap. If you look at my Tenbox (also on my website) you will see the idea. Don't forget the emitter resistors so power is shared!

New country on 6m MKS144 RX

S59A (1287km) is a new country on 6m MSK144 RX. I have spotted most of Western and Northern Europe on this mode. I am still on this band/mode.

UPDATE 0944z: 6 stations in 3 countries spotted so far on 6m MSK144 (G,S59,HB9).

UPDATE 1325z: 11 stations in 5 countries on 6m MSK144 RX now.

UPDATE 1540z: 12 stations in 5 countries now.

What will solar cycle 25 be like?

The brief answer is no-one knows. Some have predicted a long period without sunspots but some have suggested the peak could be similar to cycle 24.

In truth, we'll have to wait and see. It seems probable we are unlikely to see the massive peaks that some of us remember. If we see a peak at all, it is likely to be a modest affair.
