I bought 5 LM317s on PCB with heatsinks for a fiver:Why bother building it any longer, that used to be half the fun! The heatsinks would of cost a Quid each over here, never mind the LM317 and the PCB with connectors..Happy days73 Steve G1KQH

Another G1KQH bargain
This came in from Steve, G1KQH, today. It is often cheaper to buy the completed, built modules from China than to buy the parts in the UK! What is the world coming to?
Not amateur radio - new blog
Today I started a new blog to keep a record of our visits to churches in East Anglia. We hope to visit quite a few through the year.Although the new blog is public it is primarily a record for our own use, so any inappropriate comments will be removed.
At one time we planned a full website on this subject when we retired but a blog seems more appropriate

10m USA WSPR spots
The first spot of my 500mW 10m WSPR beacon was by KC1AWS (5308km) at 1250z.
UPDATE 2225z: The last USA spot of my 500mW 10m WSPR beacon was KC1AWS at 1836z. I went QRT on 10m WSPR a little later, so it is just possible there might have been others later, but unlikely.

Sunspots and 10m - Jan 31st 2015
Sunspot number today was 193 (high) and 10m propagation was forecast to be "good".
How do they make a profit?
On eBay I have just seen a complete LM386 amplifier kit on a PCB for $2 with free shipping. G1KQH has spotted Pixie transceiver kits for £5 with free shipping. How do they make any money?

472kHz - same stations again?
I am beginning to get tired of 472kHz WSPR as the same stations are being spotted and are spotting me. It is some time since new stations have been spotted or have been spotting me.
Starting tomorrow, I think I may try a totally new band for me on WSPR. Unsure which band to try as yet. I'll stay on 472kHz overnight in case some new stations appear.
On 10m WSPR it is a similar story, although I find watching the changing conditions of interest and the DX is real DX. The little WSPR-AXE-CW WSPR 10m beacon is also so tiny. I find it amazing that something so small and just 500mW can be heard all over the world.

10m USA WSPR spots
The first USA station to spot my 10m 500mW WSPR beacon today was KC1AWS (5308km) at 1404z. At least the band was open to the USA.
In a few years the best chance of copying the USA, or the USA copying me on 10m, will be on the rarer summer days with transatlantic Es. F2 across the Atlantic will become very rare sadly, although WSPR should help to "winkle" out such openings as long as up to 2 minutes in length. The danger is people will desert the band as conditions dive. We've already seen this happen on 6m, which is a pity.
UPDATE 2024z: The last spot of my 500mW 10m WSPR beacon was K9AN (6505km) at 1746z. Now going QRT on 10m. Went QRT on 10m at 2034z. Still active TX and RX on 630m (472kHz) WSPR.

ET/G8DYK on 10m WSPR
I have just seen that ET/G8DYK (5931km) was spotting my 500mW 10m WSPR beacon this morning a few times. This my best DX so far today on the 10m band.
Low cost kits
See http://www.aliexpress.com/store/331885 . This website has some very low cost rigs for sale. An example is a 40m Pixie at around $10 post free. You'd be hard pressed to buy the individual parts for less!
UPDATE 1430z: I have just ordered a 40m Pixie kit from them. Should be here in 2 to 3 weeks time. I hope I can manage to build it with my clumsy soldering currently.
UPDATE 2000z: G1KQH has found the same Pixie at an even better price:

Sunspots and 10m
Sunspot number today has climbed to 181. 10m is forecast to be "good".
UPDATE 1125z: So far this morning my 10m 500mW WSPR beacon has been copied by UR/SWL56 (2283km), 4X1RF (3519km) and local G4IKZ (18km). The usual reporters! I expect the 10m band will open to the USA after lunch.
UPDATE 1447z: The 10m band opened to the USA for me here after 1404z.
