Quite a few spots on 630m (472kHz) WSPR overnight,but no great DX either way (i.e. spots given or received). Best DX on TX were spots from PA land (306km). I did spot LA on RX (1035km) but he did not spot me last night.
I have now gone QRT on MF and started up the 10m WSPR for the day.

Another low cost rig from Yaesu?
See http://www.qrpblog.com/2016/04/yaesu-ft-891-new-hf50mhz-transceiver.html .
The date of this was April 1st, so this may be a wind-up. If it is, like me, you have been fooled!
YO9IRF/M0HRH reports on his blog about on the Yaesu FT891. As reported, if true, it is a mobile-sized rig covering HF-50MHz.
As I said, this could be a wind-up. Caveat Emptor. It was also picked up by Amateur Radio Weekly, so if a joke, they were fooled too!
They claim this is not an April Fool wind-up. I hope this is correct.The FCC data does look genuine enough. If a hoax it is a very complex one. The question is, if genuine, will it be available in Europe and at what price?

50W red LEDs cheap on eBay
Bernie G4HJW recently posted to the UK Nanowave Yahoo about some powerful red LEDs that he bought from China for just £2.80. A couple of these are more powerful than the 10mm LEDs that I used in non line of night tests (when I was fitter) but even without any lenses! It would seem these would be ideal for optical tests. 50W is a lot of power. This was Bernie's post. I trust he won't mind me sharing it with you all:
"Morning all - This might be of general interest:
I recently bought a couple of 50W red LEDs from China, which I thought I might use in a wide-angle initial set-up lantern for portable use. They were very cheap (£2.80), so I also expected there would be dead segments, which there were, but there was a bigger surprise waiting to show itself.
During this weeks UK uwave group net, Martyn G3UKV asked me how wide the spectrum was, so out came my trusty secondary school Spectroscope. Instead of the expected relatively narrow response, there was noticeable output right through to yellow plus a weakish narrow line at the violet end. This should have been an obvious clue, of course, but it was only later when I was telling Stuart G8CYW (sorry about all the name dropping..) that he suggested that the LEDs might be fluorescent driven devices, just like the white lighting LEDs all seem to be these days. He was correct, as the following picture shows:
http://www.earf.co.uk/uvred.JPG
Note that in pealing back some of the fluorescent gell, all but one of the individual 1W UV leds have been destroyed. Not obvious from the picture is that these LEDs are embedded in an initial clear silicon rubber prior to the red fluorescent layer being applied. From supplier ebay pictures, it is now clear that the same UV driven devices are available in all colours, leading to the question - does this produce an overall increase in efficiency, or is there simply a significant cost saving in just fabricting UV LEDs?.
I've yet to measure the response time of the fluorescent material.

Working with simple optical gear was one of my great pleasures, so I very much hope I can do this again. Optical gear is easier than microwaves. All my kit was home designed and built and the test gear simplicity itself. For details of my optical work see http://www.g3xbm.co.uk . G4HJW and others know far more than me in this area. I consider myself very much a novice in this area.

Sunspots and 10m - Mon April 4th 2016
Solar flux is 82 today and sunspot number higher at 38 (K=3). The forecast for 10m propagation is still "poor" but 10m looks a little more promising than yesterday, which was dire here.
I am about to switch on 10m WSPR.
UPDATE 1735z: No 10m WSPR spots all day.

G3XBM Projects
Yesterday, Steve G1KQH mentioned in a comment how he missed my projects. I do too!
As many will be aware I suffered a stroke 2.5 years ago. I expected to make a full recovery, but it has not worked out that way. Even now, although people tell me how well I look, I still feel giddy most of my waking hours and I tire easily. My voice is poor and I have trouble with drinks. My fine motor skills are not good. Basically, I have struggled with things that were easy in the past. I really miss just fiddling and building. Life is much harder.

Sunspots and 10m - Sun April 3rd 2016
Solar flux is 81 today and sunspot number 11 (K=3). Conditions look a little worse than yesterday. The forecast for 10m propagation remains "poor". Although I am expecting little, this band has a habit of throwing surprises.
