10m WSPR DX
4X1RF (3519km) surprised me by spotting my 2W 10m WSPR many times today. G4CUI (172km) has also spotted me on 10m WSPR. Not too bad for a band many would choose to ignore as a dead loss.
Sunspots and 10m - Wed March 23rd 2016
Solar flux is 87 and sunspot number a very low 13 (K=4). The forecast for 10m propagation remains "poor" and I really am not expecting much on 10m WSPR today. I've been on 10m WSPR for about 15 minutes but no spots, well not yet anyway. 10m is always a band of surprises so who knows what the day will bring? I hopeful of some Gs, maybe some short-skip and just maybe some South Americans, but the latter are unlikely.

Packhorse Inn - NOT amateur radio
We ate lunch with our son (pity the other one wasn't there too) at the Packhorse Inn
in Moulton near Newmarket. The food was very good and it was very busy,
which is always a good sign. This is our third visit. This medieval
packhorse bridge is just a few metres away.
QSYed to 630m (472kHz) WSPR
At about 1846z I moved from 10m down to 630m WSPR for the evening and night. It is getting a bit late in the season for new MF stations, but I remain ever hopeful. At some point I really must count all the spots with 5mW ERP on 472kHz WSPR this DX season. As you will recall, I am only using the earth-electrode "antenna" in the ground. I have managed to hear stations all over western Europe with this "antenna". It has reached Norway and Germany on TX.
Before too long I shall move to 6m WSPR as activity on MF will drop off and the Es season will really be with us on 6m. In previous years I have got to Israel, 4X1RF (3519km), several times on 6m WSPR with just 1W ERP to an omni vertical antenna. Mind you, 6m is more of a daytime band, so I will have to think about a band at night - maybe 40m.
I may try an E-field probe on 136 and 472kHz next season. These are tiny, but effective, RX antennas if carefully positioned in the garden. I suppose I could even do several bands scanning on RX. My old work colleague Bob G3WKW has used a Raspberry-Pi as a 10mW WSPR TX beacon switching across several bands. He has achieved some remarkable results - all credit to him.
UPDATE 1918z: G4GIR (53km) is a newcomer on 472kHz WSPR - well he's new to me, I think. We just exchanged spots. Also in the RX log already is LA8AV (1035km) in JO59cs. I do like 472kHz WSPR - even with my set-up I seem to get very decent results. It is a great pity more don't join in the fun. As I have said many many times, if I can get out OK then anyone can! My "antenna" proves you do NOT need lots of wire in the air and a ground the size of a football pitch. No, a very small system works. The transverter I use was homebrew and is shown in the latest edition of the RSGB book "LF Today". It is also on my website at http://www.g3xbm.co.uk . This is very simple and several versions have been built. No, before you ask, I do NOT do a PCB for this. It has an output of 10-15W although my measured ERP from the earth-electrode "antenna" is very low. To a half decent antenna just think what you could achieve!

WSPR on 472kHz already this evening |
10m short-skip
EA1FAQ (1249km) spotted me on 10m WSPR at lunchtime. A few hours later I noticed the shack PC had closed the WSPR program and shut down, presumably to install updates. I did a time resync and restarted the WSPR program about 1 hour ago. I have no idea when the PC shut down, but there have been no more 10m WSPR spots.
Our rear garden - NOT amateur radio
This was our rear garden taken this morning. In a few weeks time all the
blossom will be out. In the distance, in our neighbour's garden, is an
apple and plum orchard.
More on the IC7300
See http://yo9irf.blogspot.co.uk/2016/03/icom-ic-7300-review.html?utm_source=amateur-radio-weekly&utm_medium=email&utm_campaign=newsletter .
YO9IRF takes a look at the IC7300. MLS is offering this for sale but at a price over £1000, which may interest "early adopters", but is much higher than most are prepared to pay, I believe. Expect the price to drop soon. Even with the dollar and yen exchange rates, I think a much lower price should be expected and demanded.
£799 would seem a fair price to me. Don't forget that early radios are often riddled with bugs that later get sorted. This is the first time the transceiver will have been mass produced so it is quite likely this will occur, although not inevitable. Personally, I can wait.
I found this via Amateur Radio Weekly at AmateurRadio.com. Always a good source of data.

Sunspots and 10m - Tues March 22nd 2016
Solar flux 89 today. Sunspot number is 25 (K=2) and the forecast for 10m propagation remains "poor" today. Yesterday, with similar conditions, my 2W 10m WSPR was spotted many times in Brazil and Israel. There was also some short-skip in the early morning on 10m.
UPDATE 1035z: No spots on 10m WSPR here as yet.

That balloon again!
The Bristol balloon is now over North Africa, having been all around the globe.

Frog (or is it a toad?) - NOT amateur radio
For the first time since last summer we saw this fellow in the garden. I think it is a frog rather than a toad, but I am no expert. Last year we saw these most times we were in the garden. This one was about 10cm long, maybe less. We have no ponds in the garden so I don't know where it comes from.
