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.

Marsh Harriers and Bittern - NOT amateur radio

This afternoon we drove to Lakenheath Fen. This is 21.6 to 23.6 miles from here depending on the route.

We saw 3 marsh harriers and heard a bittern boom. There are lots of chiffchaffs around now. Sadly, no cranes.

There was a glossy ibis there which we also did not see. On the North Norfolk coast my son with his family saw some seals up close and his first swallow of the year.

Sunspots and 10m - Friday April 7th 2017

Solar flux is 85 today and the sunspot number 38. A=7 and K=2. What will 10m bring today?

Swallows return

Today we spotted our first swallow (bird) this year flying N-S over the allotments behind Burwell Museum at breakfast time this morning. In a few weeks they will be common!

April 7th is one of the earliest times I have seen these up here, although there have been reports in Devon a few weeks ago. There were days when I thought I would never live to see this day. The cycle of life goes on.
