137kHz QRSS test

On my ‘to do’ list are some QRSS tests at 137kHz using my earth-electrode ‘antenna’ in the ground and SpectrumView software on my iPhone.

630m QRP WSPR overnight

 

Overnight 17 stations spotted my 10mW ERP WSPR from the earth-electrode "antenna" in the ground.

P***ing in the wind? 10m 500uW (0.5mW) WSPR (Thursday)

My QRPP 10m WSPR is on again, although I have not had any reports for a few days.  I just leave it running ...... in hope! 

The fact I got any reports at all amazed me.

UPDATE 1845z:  No spots.

6m QRP FT8 (Thursday)

My 2.5W 6m FT8 to the vertical omni V2000 antenna has been on since about 1030z.  So far, 8 English stations have spotted me.

UPDATE 1425z: 10 stations have spotted me so far and 3 stations have been spotted here.

UPDATE 1601z: 12 stations have spotted me today.

Squirrels - NOT amateur radio

We have lived in our present home for about 10.5 years. It is about 300m from where we used to live and where we had lots and lots of squirrels. Until this morning, despite there being lots of trees, we had never ever had a single squirrel in the garden. I cannot understand why. This morning we had our first. Apart from a few areas most are grey squirrels.

See https://en.wikipedia.org/wiki/Squirrel .

630m QRP WSPR overnight

 

21 stations spotted my 10mW ERP overnight. No great DX.

Norwich

Norwich is a fine city with a wonderful Norman cathedral built of many stones, some of which came from Caen in Normandy centuries ago. 

It has a magnificent castle overlooking the city.

Sunspots - Thursday February 29th

 Solar flux is 180 and the SSN 127. A=6 and K=0.

8m amateur band?

For many years, I have advocated a tiny amateur allocation around 40.680MHz primarily for radio science research. Here in the UK, the RSGB seems dead set against this, whereas in some countries an allocation has been made.

Frankly, I think the RSGB's position is stupid. 

Surely the main purpose of amateur radio is research and self training. In the UK, if we want do research at 8m it costs us £50 annually unless we keep to ISM powers (10mW ERP).

The latest excuse is space radar to help investigate climate change, yet the latest WARC says:

"that spaceborne radars are intended to be operated only in either uninhabited or sparsely populated areas of the globe, with particular focus on deserts and polar ice fields, and only at night-time from 3 a.m. to 6 a.m. locally."

Surely the RSGB could put a good case to OFCOM for a few kHz in the ISM 8m band, NoV, limited power and modes, by application only, no-interference...

Is this likely?  Probably not. 

Instead we can go on 80m with 1kW, with commercial gear to talk about gardening. Am I annoyed? Yes.

RSGB - wake up!!

More on the SDRplay RSP1B SDR receiver

In the last few days I have not found time to play with, and familiarise myself, with the RSP1B receiver. There is a lot to learn, but on the default settings it does a credible job. 

An eHam.com review will have to wait until I have really got to grips with it. My first impressions are that it is a sensiitve on 2m and 70m as my FT817ND, but more artifacts than I was expecting.

Wicken windmill

One of our favourite walks is to Wicken Fen, where we have a bite to eat. Wicken also has a village windmill (shown in the photo).

630m QRP WSPR overnight

In the last day and overnight 21 stations spotted my 10mW ERP WSPR from the earth-electrode "antenna" in the ground. Plenty of spots from Norway, but nothing from Finland.

Our day - NOT amateur radio

On Tuesdays, we go to a free concert at the university in Cambridge. 

We grab a bite to eat first, walk through the Grand Arcade and the grounds of King's College. 

The collage here captures this.

6m QRP FT8 (Wednesday)

My 2.5W FT8 to the vertical V2000 omni antenna is on. At 1040z, spotted by 7 English stations. No spots on RX yet.

UPDATE 1622z: 13 stations have spotted me with the furthermost EA6VQ (1419km). 7 stations (all England) spotted on RX. No international DX on RX. The map shows the stations spotting me.

Sunspots - Wednesday February 28th

 Solar flux is 180 and the SSN 103. A=6 and K=1.

Electric cars - NOT amateur radio

Compared with a few years ago, there are about twice the number of electric cars on the road. Having said that, I would guess only about 1% of cars are electric. 

At the moment, electric cars are not good value. They are expensive, the range is not good enough, they use battery materials that are not commonly available and their insurance is high.

In my view, there will be lots of battery research leading to batteries that have far greater range and far lower cost cars. 

I expect a tipping point in a few years from now when electric cars will be similarly priced to fossil fuelled cars with ranges that mean charging will be infrequent. Many will charge at home on low energy deals and cars will only need charging every few weeks.

My feelings are "not yet, but soon".

It would be a great shame if the Chinese and Americans got there first and guarded all the patents.

500uW (0.5mW) 10m WSPR (Tuesday)

 My QRPP WSPR is on again. So far, no spots, although I am not surprised.

6m QRP FT8 (Tuesday)

 

My 2.5W to the V2000 vertical omni antenna is on. So far spots from 6 English stations (see map).

UPDATE 1840z: 14 stations spotted me today and 3 stations in South Africa were spotted here with the furthermost ZS6NJ (9115km). This is the first time I have spotted South Africans on 6m since the 1980s I think.

630m QRP WSPR in the last 2 weeks

My 10mW ERP WSPR from the earth-electrode "antenna" in the ground has been spotted by 56 stations with OH1LSQ (1733km) spotting me 12 times! In the last 12 hours 22 spots.

Sunspots - Tuesday February 27th

 Solar flux is 172 and the SSN 133. A=11 and K=3.

The human brain - NOT amateur radio

There about 100 billion neurons in an adult human brain. This is quite staggering. By any analysis the brain is incredibly complex.

500uW (0.5mW) 10m QRPP WSPR

 Although my beacon has been on most of the daylight hours, no spots.

630m QRP WSPR (Monday)

 My 10mW ERP 630m WSPR from the earth-electrode "antenna" in the ground was turned on about 1520z.

UPDATE 2041z:  12 stations have spotted me.

Cambridge waking up - NOT amateur radio

After what has seemed a long and dark winter, Cambridge is becoming alive again.

8m

At the moment I am undecided what to do about my 8m TX permit. 

If I want to get a permit after April, it costs me £50 per year. Running 10mW ERP WSPR under ISM rules would be free. From an experimental viewpoint running QRPP WSPR, although much harder, would be a better experiment. I am appalled that OFCOM and the RSGB seem uninterested in genuine research unless I pay!

At the moment, my inclination is to TX 10mW WSPR without a permit.

My antenna wants renewing, as I currently have a high SWR.

Almonry, Ely - NOT amateur radio

The place in the photo has been serving food since the 1200s. Luckily the cheese scones are not that old 😉😉.

630m QRP WSPR overnight

In the last day and night,  26 stations have spotted my 10mW ERP from the earth-electrode "antenna" in the ground.  No astounding DX.

Where I come from - NOT amateur radio

 This was a Facebook memory yesterday.

Sunspots - Monday February 26th

 Solar flux is 172 and the SSN 114.  A=11 and K=1.

630m QRP WSPR (Sunday)

My 10mW ERP  630m WSPR from the earth-electrode "antenna" in the ground was turned on just after 2000z. 

UPDATE 2212z:  So far, 17 stations have spotted me.

Early spring? - NOT amateur radio

Although spring officially starts March 1st according to the UK Met Office, nature thinks it is already here with lots of daffodils and blossom already out. In my view we are several weeks early. Is this global warming?

630m QRP WSPR overnight

 

In the last 12 hours, my 10mW ERP has been spotted by 19 stations including 2 from Norway.

RSP1B SDR RX

SDRs is one area of our hobby not really explored. A few days ago I purchased the SDRplay RSP1B. 

It was connected up briefly yesterday after downloading the software, which was very straightforward. It is good being able to cover 1kHz to 2GHz with the SDR. 

I think there may be some noise from the PC getting into the RX, so I may add some ferrite chokes to the USB cable later. Watch this space!

UPDATE 1142z:   I am surprised by the number of artifacts. Adding chokes made no difference to LF/MF noise floor, so noise must be external.  I tried several antennas. Next thing to try is a sensitivity test on various bands using the FT817ND and the same antenna each time.

UPDATE 1232z:  Tested 70cm sensitivity comparing the strength of the Leicester beacon. On my 2m big-wheel omni antenna this is just on the noise level on the FT817ND. It was much the same on the RSP1B with the same antenna. This suggests the 70cm sensitivity is similar. Next is to try the Kent beacon on the two rigs on 2m.

UPDATE 1550z: Still learning, but 6m, 2m and 70cm beacons copied OK. Nice seeing whole bands at a time.

UPDATE 1812z:  Would I recommend it? It is great to see the whole way from 1kHz to 2GHz and to be able to just click on a signal.  If you do not have a general coverage RX, probably yes. Otherwise I am not sure. I need to learn more!!

10m QRPP WSPR again (Saturday and Sunday)

After success on Friday, my 500uW (0.5mW) beacon is on again with the PA turned off. It was also on Saturday with no spots all day.

UPDATE 1825z:   No spots. I think another day has passed with no spots.

Sunspots - Sunday February 25th

 Solar flux is 179 and the SSN 106. A=7 and K=3.

630m QRP WSPR overnight

 

In the last 12 hours 27 stations have spotted my 10mW ERP including some useful DX (see table).

Our amaryllis plants - NOT amateur radio

 Over the dreary winter months these help to brighten things up. Even better with a blue sky!

UK amateur license changes

Whilst I understand recent OFCOM changes to the UK amateur radio licenses, I am disappointed that power levels have been increased. Having worked all over the world with 10W pep SSB many years ago and now with even better modes like FT8 available, why do we need more power? 1kW linears are VERY expensive, re-enforcing the message that amateur radio needs deep pockets for rigs, linears, towers and beams. 

As I hope I have shown, deep pockets and high power are definitely NOT needed to have fun or work the world. I hope more stick with foundation licenses!! You can work the world, and have far more fun, for the cost of a few pints of beer or a good night out.  

You definitely do not need to spend much money or run loads of power!!

Sunspots -Saturday February 24th
