6m 5W FT8 (Sunday)

Late Sunday, I went on 6m FT8 with 5W to the V2000 vertical omni antennas. 5 English stations spotted me. Now QRT.

My favourite band - 10m

Over many years, I have had most fun on 10m. Initially, I was on SSB, AM and FM on that band with a low wire dipole. Of course, on 10m antennas are small and CB antennas usually work.

These days, because of my poor voice following my 2013 stroke, I use digital modes like FT8 and WSPR mostly.

DXCC was worked on 10m QRP SSB with a simple wire dipole over 40 years ago, so DX chasing is no longer important. I am more interested to see where my QRP is reaching. That's one of the joys of our hobby: there are so many different ways to enjoy it.

Before my stroke I enjoyed experimenting. I still do, but restrict myself to what I can do at home that does not require soldering or fine motor skills!

A real experimenter

Thanks to DX Explorer, I was pointed to the website of LA6NCA who is a true experimenter. I had not visited his site before. It also looks like he has a good range of test gear. Certainly a site for inspiration.

DX Explorer website

Just now I was watching a video on this website. Then I realised it was derived from one of my designs!  I am flattered and hope he really has fun. He is eventually making a tiny PCB for it.

This was last week on a lovely cold and sunny day.

8m FT8 RX (Sunday)

Today, I am on 8m FT8 RX, more in hope than expectation, using my end-fed long wire antenna. I have no idea of the polar plot on 8m, but it has been used to copy CT, EA and G on 8m FT8.

UPDATE 1455z:   No spots.

Time and consciousness

We think of time as absolute, but we experience time differently when we sleep deeply and indeed as we age.  It may be that our understanding of time is totally wrong.

5MHz operation

Some years ago I tried WSPR on this band. 

As I recall I used the coax up to my 2m big-wheel antenna and a mains ground. It worked and I got quite a few reports. The auto-ATU in the rig was used to match the random antenna.

Unfortunately, this part of the spectrum is controlled by the military in the UK. As a result, the UK has a fragmented set of allocations and has never adopted the WARC allocation. Although we are allowed more power and more spectrum, I personally would prefer a contiguous, if narrower, allocation at lower power.

To me, it is all too confusing. I suspect many do not use the band because they are confused by the allocations. There is a band plan on the RSGB site.

2m ultra QRP FT8 (Saturday)

 Although at 3.2mW I can see my 2m FT8  signal at the grabber at G0LRD, at 26km I cannot see myself on PSKreporter. I shall increase my power until I am I decoded.

UPDATE 1815z:  Increased to 6.4mW. No decode.

UPDATE 1829z: Increased to 12mW. Decode appeared on PSKreporter (just).

UPDATE 1837z:  Increased to 25mW. Decoding, but not reliably. I think both G0LRD and I have big-wheel omni antennas.

UPDATE 1900z: Increased power to  35mW. No decodes this time.

UPDATE 1917z:  Increased power to  45mW. No decodes.The other variable is S/N at the RX.  What I am looking for is what level I need to get reliable and repeatable decodes.

UPDATE 1928z: Increased power to 55mW. It would appear that I am being defeated by local noise. No decodes.

UPDATE  1940z: Increased power to 60mW. No decodes.

UPDATE 1958z:   Increased power to 65mW. 2 people now spotting me.

UPDATE 2117z:  Increased power to 100mW. A surprise QSO with M0WDN at 100mW with a 15dB attenuator in the input of the RX!! The S/N at G0LRD seems to vary widely suggesting he was pointing a beam in a different direction. I have now gone QRT. 

Getting harder?

In all the years I have been involved in amateur radio (it started in 1961!) my main interest has been QRP (low power). 

In recent years the local noise level especially in urban areas has gone up, mainly because we have more gadgets and chargers. These often use switched mode power supplies which can produce a lot of noise. Taken together these can increase the noise floor. The result is weak signals can be buried in the noise.

Sadly, this means QRP operation can be harder. 

The problem is not so much the low power but the noise floor at the receiving end. If you have an electrically quiet QTH, you can still dig these signals out. Such sites are becoming rarer.

Probably there is a power below which it gets much harder.  At very low power it is easy to be clobbered by a stronger station as well. 

Thinking of the future, I suspect 5W QRP will be a good choice.

Trump pardons drug trafficker

Some times (many times actually) I question the motives of US President Trump. 

Allegedly, he has just pardoned the former president of Honduras who was jailed for 45 years on drug trafficking charges. I find this at odds with the "make America great again" movement and keeping drugs out.

Many Americans voted for him, so I would be interested to hear their views.

15m 100mW FT8 (Saturday)

At 1217z, I changed from 100mW 15m WSPR to 15m 100mW FT8. Now, FT8 is about 10dB worse than WSPR, but there is more activity on FT8 these days.

UPDATE 1340z:  Just. one spot of me by SP9WTC (1480km). Maybe I am being clobbered by a stronger station? Also, I suspect it is increasingly likely that QRP signals are now buried in noise, making QRP operation harder than it once was. Even with a 15dB attuenuator in circuit right next to the rig I am spotting 119 stations. This suggests an effective power of low watts if they were running 100W.

UPDATE 1708z:   Well it helps if you use a 15m antenna!  I discovered I was using my 2m big-wheel antenna rather than my end fed HF antenna. So I am surprised to have got any spots with 100mW 15m FT8.

Swaffham Prior

This is the next village from us going towards Cambridge. 

It is unusual having 2 churches in the same churchyard (don't ask me why!) and 2 windmills. 

It is a sleepy village on a rare "hill" overlooking the fen.

100mW 15m WSPR (Saturday)

For a complete change I am trying 15m 100mW WSPR.

UPDATE 1117z:  Just 6 spots from a station in Austria.  These days, although less sensitive,  there seems to be far more activity on FT8  than WSPR.

UPDATE 1212z:  Still just 6 spots of me from OE3GBB/Q (1233km). If I was starting out, I think you are more likely to have success with QRPP on FT8 rather than WSPR. QSYed to FT8.

Saturday plans

 Today I think I will try 15m WSPR at 200mW or less.

Ely Cathedral sun

 Earlier this week we went to Ely. 

The cathedral is at the top of the “hill “ and can be seen for miles around.

This was the sun shining through a stained glass window.

2m 5W FT8 (Friday)

At about 1715z, I QSYed tp 2m FT8 with 5W to the big-wheel omni antenna.  

So far 12 stations have spotted me with the furthest EI2FG (565km). 

I am convinced this is some kind of scatter.

Stations spotting my 5W
FT8 to the omni
UPDATE 1841z:  Since about 1835z I have been vertically polarised with my V2000 vertical omni. This is fed with CB RG58 coax, so I would guess the ERP is similar. It seems to make little difference which rather supports the scatter theory.

UPDATE 2125z:  22 stations in 6 countries spotted my 5W FT8 this evening. See map. Now QRT.

One of our friends made and decorated these cup-cakes by hand. 

If I had tried to decorate them, they would have looked a mess!
