Elecraft

Elecraft K4 transceiver
Elecraft make some fine products, although they tend to be a bit expensive here in the UK. In the past, I have owned a K1 4-band CW transceiver and a T1 ATU. Their latest newsletter highlights the K4, which is Elecraft's new SDR transceiver. Sadly, this will be too expensive to buy for me, much as I would love one.

Beofeng portables

These seem to be "iffy".

They are very low cost, but the quality control seems poor. Some work well, whereas others may be very deaf. It seems to me like the Chinese are still on a learning curve.

At the moment I am not inclined to spend much money on Chinese amateur radio gear. They can do it - see for example of the Apple iPad.

20m FT8 with the tiny indoor loop

A few moments ago I QSYed from 17m FT8 to 20m FT8. Although no-one has spotted my 2.5W yet, it is working on RX with 21 stations spotted so far with AB1EP (4941km) as best DX spotted here so far on 20m FT8 RX.

UPDATE 1514z: With 2.5W and the tiny loop indoors the best DX is ES5RY (1791km). SWR is 1:1.  On 20m FT8 RX 68 stations spotted so far today.

UPDATE 1529z: Changed rigs so now running 6dB more on 20m FT8 TX.

Stations spotted to about
1545z today on 20m FT8 RX
UPDATE 1610z:  Now 97 stations spotted on 20m FT8 RX with best DX spotted K6OK (8413km). It really annoys me that the FCC has really messed up USA calls! At one time K6 would have been somewhere like California. Now K6 can be anywhere. It happens to be California in this case.

UPDATE 1627z:  IU6JJE (1570km) was spotting me strongly. Even with my 10W to the tiny indoor loop he was copying me at -9dB S/N on 20m FT8 TX!  On 20m FT8 RX, 106 stations spotted so far.

20m FT8 TX (10
or less) today
UPDATE 1816z:  8 spots of my 10W 20m FT8 so far today. On 20m FT8 RX 139 spots so far.

UPDATE 1900z: After a QSO on 20m FT8 with an EA5, I have now gone QRT on all bands.

365project - NOT amateur radio

Firstly, to avoid all confusion, this nothing at all to do with Microsoft Word 365! If you want, it can be totally free. For not much you can have total privacy and multiple albums.

For many years my wife and I have sent a picture a day to 365project.org. I think we both started in 2013. Some use this as a way of posting wonderful photographic creations. Others, like my wife and I, just use it as a visual diary. We would win no prizes!

If you have grandchildren, it is good to look back every day and see how they have developed. When we have visitors we can say exactly when they last came! You can look back each month right back to when you started.

You can also, if you want, look at other people's photos. No great photographic masterpieces are needed. Photos can be uploaded by email if you want. Altogether great fun. My user name is g3xbm and my wife foxes37.
The photo shows the snapshots for August 2019. Clicking the individual photos on 365project brings up the full sized images.

481THz

This popped up as a Facebook memory from 2012. It shows G4HJW's optical signal received on my kit "over the horizon". There was no signal visible. This encouraged me to carry out my own experiments.

17m FT8

Last night I decided not to go on any band although this morning I am on 17m FT8 RX with the tiny indoor loop antenna.

UPDATE 1032z: 21 stations spotted so far today on 17m FT8 RX. Best DX spotted here so far is 9K2HN (4632km).

17m FT8 RX spots to 1300z today
UPDATE 1300z: Now 40 stations spotted today on 17m FT8 RX with best DX spotted being HS5XWY (9469km).

UPDATE 1327z: I have just decided to try 17m FT8 TX (2.5W) with the tiny indoor loop antenna. Already I have been spotted well in the Canary Islands by EA8BEV (3126km).

Cambridge bookshops - NOT amateur radio

When I first came to Cambridge about 50 years ago, there were far more bookshops than now. The biggest was Heffers with several shops scattered across the town. Heffers is now owned by Blackwells of Oxford I think.

I guess many people buy their books on the internet instead (in the main, I do), although browsing through books is still a pleasure. In 20 years' time what will we do?

There are still a few independent second-hand bookshops around. One of these is David's shown in the photo. This has remained much the same over 50 years.

Sunspots - Wednesday February 26th 2020

Solar flux is 71 and the sunspot number 0. A=3 and K=1.

2m FT8

Since returning from Cambridge I have again been on 2m  FT8 with 10W to the big-wheel omni antenna

So far, 7 spots of me in 3 countries with the best being a spot by GI6ATZ (479km) in N. Ireland. It seems nearly every time I go on 2m FT8  he copies me!

Fewer stations spotted here. Tropo conditions seem dire.

UPDATE 2105z: 12 stations in 4 countries have so far spotted me on 2m FT8 this evening. Best DX is a spot of me by EI3KD (583km).

UPDATE 2318z: QRT.

OFCOM - thank you!

OFCOM is usually an organisation I complain about, but today I want to say thank you. Yesterday I forgot my password. Today I got an email to get a new one and an email to say my amateur licence had been revalidated to 2025. The person who handled the query showed initiative - thank you!
