An aging mainly male hobby?

My comment on ours being a hobby mainly of older men has received quite a few comments on amateurradio.com. Not sure of your view, but our hobby will have to change in the coming years or it will fade away. What interested us may not be the same for young people in the 21st century.

There are some ideas here which we should think about.
See http://www.amateurradio.com/hobby-30-years/#comments .

One example from CN8VY:

Roger,
I agree with you 100%.
Ham is missing one after the other all the game-changing opportunities: the wifi-wireless revolution, Drones becoming general consumer goods, solar and alternative energy, the need of a fitter lifestyle (trecking and extreme sports), the global outcry for Solidarity, etc
All the items I have mentioned here are of concern to men, women, kids all over the world. We ham are unable to contribute seriously to them and “surf” the wave and get newbies. Let me make myself clear with one example. If you go to a public park anywhere in North America or Europe, set up a small solar panel or a wind generator, start using a small radio to send GPS data or weather bulletrins, you will get a lot a lot a lot of attention and interest. You will see teens and young active adults come and ask you about the set up. Initially, they don’t care at all about RF. They are attracted by the solar stuff and the resilience to power shortage. This is the good starting point to convert may be 10% of them to ham.

Southgate News reports that this balloon has crossed the Pacific Ocean.

Some notes on WSPR 4 from G3UDI

This came from Bob G3UDI:

A few notes on WSPR-4
Downloading software Follow George M1GEO: http://www.george-smart.co.uk/wiki/Compiling_WSPR Linux and Windows. Another useful site is VK2TPM: http://blog.marxy.org/2014/11/wspr-on-ubuntu-1410.html Linux only. I used older instructions as here: http://www.george-smart.co.uk/w/index.php?title=Compiling_WSPR&oldid=5027 I am using Linux Mint-17 and have no direct experience of running WSPR under Windows.

Issues WSPR-4 is a bit flaky, particularly in uploading to the database and maps, in both Linux and Windows. There is a newer version, WSPR-X, and this appears to be even more flaky according to various forums.

Uploading Spots to WSPR database: Spots are held in file ALL_WSPR.TXT. This file is a complete log of all WSPR activity rx and tx. It can be cleared from the gui. The location of the file is not too obvious: ~/.local/share/WSPR/ALL_WSPR.T

XT They are uploaded to the WSPR database. Confusingly there are references to the "old database interface" although this is the working interface. 1. In real time: check "Upload spots" box in WSPR gui; starts from the time when the box is checked. Sometimes data is not shown in interface, but it is always registered. 2. To upload all new spots manually. Open site http://wsprnet.org; click on "Database" in top right- hand corner; scroll to bottom of Database; click on Link to old database interface. Enter callsign and Maidenhead locator. In the box labelled "Location of ALL_MEPT.TXT" enter the location of ALL_WSPR.TXT. Then click on "Upload spots".
3. To upload all new spots automatically.

1. Obtain a copy of curl. In linux : sudo apt-get install curl . This is a general program for transferring data to/from a server, with a huge number of options. 2. The key command is, all on one line: curl -F allmept=@Desktop/ALL_WSPR.TXT -F call=g3udi -F grid=JO02de wsprnet.org/meptspots.php Desktop/ALL_WSPR.TXT is the location of ALL_WSPR.TXT, callsign and Maidenhead locator are obvious, allmept is the receiving file at the wsprnet target. The rest of the mumbo-jumbo are curl options. 3. Under Windows the procedure is similar. 4. See attached for my Linux script and the Windows option of N8FQ, taken from the WSPR site. Also screenshot of operation using HiQSDR + Quisk software.

Dull again - NOT amateur radio

Spring flowers
We have had a mild, wet winter here in East Anglia, UK. There have been more muddy, wet puddles than I can ever recall. I have lived in this part of the UK since 1970.  They were forecasting a very cold winter. Mind you, they said this last year! At some point they will be correct. Most spring flowers came out very early.

It re-enforces my view that the most reliable forecast is to look out of the window! We had rain last night, but I don't think it was forecast.

Sunspots and 10m - Friday March 18th 2016

Solar flux and sunspot number are both 66 today. K=3 and the forecast for 10m propagation remains "poor" today.

UPDATE  1045z:  Not surprisingly, no spots on 10m WSPR, as yet.

UPDATE 1218z:  Just a single spot of my 2W by G4CUI (172km) on 10m WSPR, so far. It is very very quiet here at the moment with no DX spotted or spotting me.

472kHz WSPR overnight

Last night, I followed my usual pattern and closed down on 10m and 6m WSPR and went on 630m WSPR overnight.  My 5mW ERP WSPR on MF was copied in Norway again by LA3EQ (769km). Otherwise nothing special, although I was copied in Belgium and Holland again on 472kHz WSPR.

I have now QSYed to 10m WSPR (2W 20% TX, 80% RX).

Ickworth (National Trust) - NOT amateur radio

Lambs at Ickworth


As members of the National Trust, we are very lucky to have several properties with fine grounds nearby.  Today, as the sun was shining, we went to Ickworth not far from Bury St Edmunds. Although there were lots of lambs, the daffodils are still not out, in the main. A few are, but most are still in bud. All the NT places nearby are very different. We also made use of our free "tea for 2" voucher which came with a card.

Back on MF WSPR overnight

As it now after dark, I have gone QRT on 6m and 10m WSPR and QSYed to 630m (472kHz) until after breakfast tomorrow.  So far, the best DX on RX is LA1TN (1269km) and on TX (5mW ERP) G6AVK (78km).

On 6m and 10m WSPR

Local G4NUA (12km) was exchanging strong spots with me on 10m, so I decided to swap to my W5OLF 10m WSPR beacon (500mW) and use the FT817 to go on 6m WSPR at the same time (1W ERP vertical). The W5OLF beacon takes about 20 minutes to settle before I start getting reports.

UPDATE 1718z:  No reports, well not yet anyway, of my 500mW beacon on 10m WSPR. G8VDQ (93km) has been spotted several times on 6m WSPR.

10m and 6m Es

The sporadic-E (Es) season will soon be with us in the northern hemisphere. This usually peaks May to July, although there are openings less frequently outside these times. I shall probably return to 6m WSPR soon in the hope of catching some short-skip DX on the band. If I go on 6m, I shall return to the W5OLF beacon on 10m. This stand alone 500mW WSPR beacon runs 100% TX but randomises the TX frequency within the WSPR window. In previous summers I have been copied by 4X1RF (3519km) on 6m WSPR. Although the conventional wisdom is that this is multi-hop Es, I have my doubts. Es yes, probably, but some sort of chordal hop?
