Still quiet on 10m WSPR

Apart from a single spot for G4CUI (172km) this morning, nothing spotted, or spotting me, on 10m WSPR today. I am sure it is a lack of activity rather than poor conditions.

Sunspots and 10m - Mon March 14th 2016

Solar flux is 95 today. Sunspot number is 43 (K=2). The forecast for 10m propagation remains "poor" today.

I have been active on 10m WSPR since about 0715z.

UPDATE 0912z: So far just G4CUI (172km) spotting me on 10m WSPR.

10mW WSPR by G3WKW

My old work colleague (of long ago) Bob G3WKW has been experimentally frequency hopping on WSPR and has achieved remarkable results with 10mW from his Raspberry Pi. He has been hopping 160m to 10m. Note the spot by K9AN on 15m! Not bad at all for 10mW and a stand-alone PC.

24hrs hopping with 10mW WSPR by G3WKW

Return to 630m (472kHz) WSPR

For about 30 minutes now I have returned to 630m after a day on 10m WSPR. The first and second stations spotted were in Norway and Germany. Both these were stations I have seen before.

472kHz WSPR spots so far this evening

UPDATE 2222z:  Best DX on 472kHz WSPR TX (5mW ERP from earth-electrodes) so far tonight is PA7EY (306km). Best DX on RX so far is LA1TN (1269km).

U3AC - NOT amateur radio

Mondays this term I have been attending a University of the Third Age course in Cambridge. I go into, and out of, Cambridge on the bus using my (free) bus pass.  I am doing a course called "Living with less". Although I often disagree with the lecturer, I find the course informative.

As I usually have some time after the course, I get a bite to eat in different places in the city. At the moment my favorite is Le Patissier, opposite St John's College. This is a small place, but prices are reasonable and I have found the service very good.

Spring at last

Rear lawn after first grass cut

The Met Office (our UK weather bureau) treats the start of spring as March 1st. Well, there was no doubt that here it is now spring. Today I cut the back lawn for the first time since the autumn.

It was a day of b's: bench, beer (on the garden bench after doing the lawn), buzzard (overhead), bees, butterflies, blooms and blossom. Today really felt like a spring day. We have had a mild, wet winter but it has seemed endless. Today, the garden was calling.

Oh to be in England now that spring is here.  Honestly, there were times when I thought I would not see it.

This is another view of the rear garden in which you can see the V2000 (6m, 2m and 70m vertical) and the big-wheel (2m horizontal omni) antennas. If you click on the image you may be able to make out the 2m halo and maybe my wire for 10m, 20m and 40m. Not visible is the earth-electrode "antenna" in the ground which I use on 472kHz TX and RX.  With 5mW ERP using the earth-electrode "antenna" on 472kHz WSPR I was received in Norway again last night.  Next autumn I must get a long wire for LF/MF strung up!

Another OFCOM cock-up? - NOT amateur radio

Southgate News reports on what some will see as another sign of OFCOM incompetence. Why did we chose the old standard?

See http://www.southgatearc.org/news/2016/march/millions_of_tv_sets_may_become_obsolete.htm .

OFCOM? Fruitcakes.

Stroke update - NOT amateur radio

It is hard to see any improvements now 2.5 years after my cerebellum brain bleed. If improvements are occurring then they are so small they are not noticeable. I still feel giddy on my feet and I still feel sick most of the time. My liquid swallow is still poor as is my voice. I still get exhausted very quickly.

If any improvements now come, they are a bonus, but I guess I have to adapt to life as it is now, much though I would like my "old" self back. It means I am very restricted when using voice modes like SSB and FM on the air: every QSO is hard work. This is one reason why I am a fan of WSPR: I don't have to use my voice. Field experiments and building have had to take a back seat, although who knows in the future?  We are blessed with a great hobby and, despite my poor health, I am able to enjoy it still.

A very simple QRP transceiver for 80m CW - the XBM80-2

I received this yesterday from Martin G0PJO:

Hi Roger,

G0PJO's rig in the field

I thought you might like to know that the QRP rig works and I’ve just returned from the field (the only place I can put up my 80m dipole) having had a successful QSO with G3XVL just over 4.5 miles away in Ipswich. He gave me a report of 599. The only issue that I had was with the audio level on receive. I’m using a crystal earpiece and I really had to listen but we managed a 30 minute+ QSO!

Many thanks for publishing the design.

This very very simple transceiver for 80m CW is on my website. See the direct link at  https://sites.google.com/site/g3xbmqrp3/hf/80m_xbm80.  There is also a video link. 

For all my projects go to http://www.g3xbm.co.uk . Because of my poor health I have not built anything original for some years.  I very much hope to get back to experiments soon.
