 This morning I received this email from KK4HSX saying that (certainly in the USA) Amazon is already selling wifi connected slow cookers called “Crock Pots”. Not sure if this is a stateside generic term.

It’s already here. Behold,the Crock Pot you can monitor and control with you phone.

Landwade was the site of my first “over the horizon” optical tests. The tests were successful, but predate my stroke by some time. I remember well being surprised at the reception when “on beam”.

We go here each year about this time for a delightful walk of about 1.5km calling at the small private church (locked these days). The church is surrounded by seas of snowdrops and aconites at this time of year. Landwade is very quiet at all times. It is in Suffolk but was in Cambridgeshire until 1994. It has been occupied since Roman times, but consists of a few farms, a hall and the odd cottage these days.

I have updated one of my other blogs.

An amateur band at 40MHz would be really useful as I suspect the F2 MUF has been in this region several times in the last few years. There are a very few beacons around 40MHz (UK and Denmark only I believe) but wouldn’t it be good to have even 100kHz around this frequency? Sadly it is very unlikely, but I would happily lose 100kHz at the top of 10m in exchange.   It would also be a very useful Es band.

Somehow I can’t see this happening, more is the pity.  The world of radio science would really benefit. This would have been so much more useful than 146-147MHz recently released to UK amateurs by NoV.  I know a handful of UK amateurs are trying narrowband DTV but the 2m band is mainly Japanese “black boxes” and is mostly white noise in most areas.

The Tenner is a very simple CW rig for 10m. It produces about 500mW output and has worked across the Atlantic on many occasions. Offset RX-TX seems to work out at about right, although no special circuitry is employed. This simple circuit just works. Although I used an “at hand” SBL1, any double balanced mixer is likely to be OK. Although I did not try it, a homebrew DBM would be fine.

My low cost 40m Pixie kit – although G1KQH only paid about 60% of what I paid – is on its way from China but has not yet arrived here. I assume, with free shipping, this comes by sea. I am in no great hurry. As I mentioned before, I very much hope to build this unit as I have not built much in ages because of my brain bleed.

UPDATE 1600z:   My kit arrived in the post today.  Still to open the package, but judging by the speed this must have come by air. It looks well packed.

In all my time in amateur radio I have never once experimented with microprocessor programming and I have done very little “digital” design.  This seems to be a gap in my knowledge, although I am still not really interested, preferring RF design, especially QRP.  I must say I remain very impressed with Wolf’s (W5OLF) tiny WSPR-AXE-CW beacon: this goes to show just how much can be achieved with so little physically. Maybe this is a whole area I should embrace? The trouble is it is impossible to be an expert at lots of things, unless you are very bright. Certainly I do not consider myself a polymath!
