10m and 6m Es

In the last 24 hours there has been plenty of European Es on 10m WSPR, but none on 6m WSPR.

Salcombe - NOT amateur radio

Salcombe - I used to live in Coronation Rd which is central in this shot
This morning we went for a walk at Snapes Point, overlooking Salcombe (where I used to live as a child) and the Kingsbridge Estuary.
Kingsbridge Estuary, S. Devon
This is our last full day in Devon. I have been pleasantly surprised that I have been able to do so much. We'll be back.

Sunspots and 10m - Thurs May 19th 2016

Solar flux is 101 today. The sunspot number is 28 (K=1) and the forecast for 10m propagation (F2) remains "poor".

Crab sandwiches - NOT amateur radio

Salcombe crab sandwiches
This evening we did another walk ending with a pub meal. Lis had a crab salad and I had crab sandwiches and Tinners beer.

G3TDZ SK

I missed this but G3TDZ, John Hey is a silent key now. He wrote a very nice article in Wireless World on a 2m AM handheld some years back and was inventor of the Heyphone which was widely used by cavers. He did a version for the 73kHz band too. He wrote to me several times. I think he died earlier this year.

TEP at 10m, 6m and 2m

Although 6m Es has been rather quiet, there was some TEP between Japan and Australia. TEP often allows stations across the magnetic equator to work each other at MUFs far above those expected. I think chordal-hop is involved. TEP between the Med area and southern Africa has even occurred at 2m!

In most recent years there has been 6m propagation between Japan and Australia. This mode may well account for some of the N-S propagation on 10m. It favours stations a bit nearer the equator. In the UK we need Es as well to get us into the area where there is TEP. Just occasionally it happens this far north.

Bolt Tail - NOT amateur radio

Our holiday continues.
This is the view looking west from Bolt Tail in South Devon, UK. On the RHS is Burgh Island. We dodged showers! Real April weather in mid May.  Bolt Tail was once a promontory fort thousands of years ago. It would be wonderful to have seen the view back then - few settlements, the coast would have been further out, etc..

See https://en.wikipedia.org/wiki/Promontory_fort .

The walk from Bolt Tail to Bolt Head along this coast is spectacular. We parked on Bolberry Down.

Sunspots and 10m - Wed May 18th 2016

Solar flux is a respectable 104 today. Sunspot number is 36 (K=3) and the forecast for 10m propagation is still "poor".

6m WSPR - Es at last

There was Es in evidence in Europe today on 6m WSPR. Now it has started, we can expect Es most days on this band. When there is Es about on 6m, it can be a really fun band. Even with 6m SSB, just low ERP is needed to work all over Europe and North Africa.

IARU

See http://www.iaru.org/ .

The IARU is the "umbrella" organisation guiding the amateur communities around the world.

In region 1 I very much hope that a 100kHz wide 5MHz band will be allocated to radio amateurs in Europe despite a 15kHz wide band being allocated worldwide at WRC15.

There is quite a bit going on to persuade amateurs to adopt a new band-plan for 6m which involves relocating beacons slightly further up the band. It will mean more space for CW lower down, as for most HF bands.
