QSYed to 10m JT65 transceive

In the last few minutes I have moved from 6m MSK144 RX to 10m JT65 (2W) transceive.

It remains to be seen whether I spot anyone or anyone spots me. Conditions may allow some N-S DX as long as there is activity!

UPDATE 1635z:  Still no 10m JT65 spots.

UPDATE 1930z: With no 10m JT65 spots I have now gone QRT.

70cm UKAC tomorrow evening

Tomorrow evening is the next 70cm leg of the RSGB's activity contest. Although we have visitors, I can only run 5W, and have no suitable 70cm antenna, I hope to come on briefly.

Dandelions - NOT amateur radio

Although officially a "weed", dandelions and daisies are everywhere now. These signal spring and that we are no longer in winter. To me, they are cheerful flowers.

New country on 6m MSK144 and new DX record

IS0AWZ (1596km) was spotted on 6m MSK144 RX this morning. This yet another new country and a new DX record on this band/mode I think. So far 6 stations in 4 countries on 6m MSK144 RX today.

UPDATE 0900z:  8 stations in 5 countries so far spotted on 6m MSK144 RX this morning.

UPDATE 1345z: 12 stations in 7 countries so far today on 6m MSK144 RX.

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.

See https://sites.google.com/site/g3xbmqrp3/hf/wispytx

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!
