Backpacker's beach party in Australia - NOT amateur radio

The BBC news is carrying photos of a backpacker beach party in Australia. People are understandably appalled by such stupid people flouting the rules. Many were from the UK. 

Some may get deported. Quite right. So they should for such crass stupidity. 

At the moment there have been new outbreaks in Sydney which the authorities are trying to contain.

15m QRP CW

It seems amazing that I designed and built my Pipit 15m CW QRP transceiver so long ago!  For a long time this was my main rig and gave me lots of fun. These days FT8 is ousting SSB and CW, but you would be hard pressed to find something as simple as this that really works so well.

6m FT8 (QRP) Tuesday

After a really good day yesterday, I am again on 6m FT8 with 2.5W (FT817ND) and the V2000 vertical omni antenna. It is now 0940z and I have been on for about 3 minutes.  Already spotted by G0PQO (50km), with just G0DYW (77km) spotted on RX.

UPDATE 1149z:  4 spots of my QRP TX in 2 countries and 17 spots in 4 countries on 6m FT8 RX today. Definitely winter Es about on 6m FT8.

UPDATE 1435z:  27 stations in 6 countries spotted so far on RX, and I have been spotted by 8 stations in 3 countries on 6m FT8 QRP TX.

USA spoilt child? - NOT amateur radio

Without mentioning any names (I am sure you can guess) there appears to be a really spoilt child throwing his toys out of the pram in the USA. Does this person not realise the harm to his future reputation? Please, stop being so childish!! Just grow up.

Yet more homes - NOT amateur radio

 


Every spare space in our village seems to be being used for new houses. This is one plot yesterday.

Label making video

Jason M0NYW has sent me this video on how to make professional looking labels.  Well worth looking at. Look at Jason's example, which looks good to me.




G3XBM video channel

Some of the videos on my YouTube channel may be of interest, as are some of the pages on my main website. Many of these are quite old and probably are in need of an update!

Memories - NOT amateur radio

At breakfast my wife and I were counting up how many walks we had been on this odd year. We keep a record each month. At one point she said a figure and I said she had miscalculated. Without a recording, we can never be sure who was wrong. 

This makes me wonder what other memories may be wrong. Memory is an odd thing: as I said some weeks ago, we think we remember things in the past, but it is entirely possible time is a human construct and each day is new with memories we think we have. This is getting too heavy!

My apologies - 136kHz transverter

Some time ago, I was asked by email if the technique to make this into a full TX-RX transverter as used on 472kHz could be adapted on 136kHz. What happens sometimes with emails is that they get filed and forgotten about. I do not remember replying to this question. So, if I did not answer this please accept my sincere apologies. I just cannot remember.

Yes, the same techniques would work on 136kHz, suitably scaled. This could be a simple way to get on this band. I have to confess I have never been on 136kHz TX from this QTH!

6m FT8 QRP (Monday)

After breakfast I hope to go on 6m FT8 with 2.5W and the V2000 vertical omni antenna.   This is now the winter Es season, so it is possible some European stations will be spotted. Yesterday was very promising on 10m. 

UPDATE 0907z:   Already spotted in Sweden by SM4CHK (1138km) on QRP FT8 TX and 16 stations spotted on RX from Scandinavia. This definitely looks like winter Es.

UPDATE 1100z:   Already spotted by 6 stations on QRP 6m FT8 TX right across Europe!  No QSOs.  27 stations spotted so far on 6m FT8 RX again right across the continent with the furthermost being LB7FA (2008km).

UPDATE 1316z:  I have been spotted by 10 stations across Europe with my 2.5W QRP 6m FT8 TX and I have spotted 45 stations on 6m FT8 RX.

Stations spotted
to 1515z on 6m
FT8 RX
UPDATE 1515z: 1 QSO with an LA station.  67 stations spotted on 6m FT8 RX. 14 spots of my QRP 6m QRP  on 6m FT8 TX.

UPDATE 1532z: 70 stations spotted on 6m FT8 RX. 2 QSOs  (LA and DL).

UPDATE 1712z: 18 stations have spotted my 6m FT8 QRPoday. TX with the furthermost being IS0YFG (1600km).  82 stations spotted today on 6m FT8 RX. This looks like winter Es.

Stations spotting
me today
UPDATE 1819z: 
QRT soon.  85 stations spotted today on 6m FT8 RX today.

10m (28MHz) - my best band

Although, at the moment, 10m is not a great DX band, this will soon change. Within a few years it will again be one of our greatest DX bands. Even with simple antennas and low power, worldwide DX should be possible. Being 1.7MHz wide there is space for all modes. Even a wire dipole is very small.

With my poor voice I find FT8 better than SSB or AM or FM. It will be interesting to see the impact of FT8, which is already very popular on many bands. I like it as most DX is concentrated in a few kHz and there are lots of people monitoring.  It works with signals weaker than SSB or CW. Being a very narrow-band mode (each TX takes about 50Hz only) it seems better with man-made noise than wider band modes. 

I suspect there may be less AM activity this cycle, which would be a pity: often operators use old "boat anchor" rigs with beautiful modulation. In the last (poor) sunspot cycle several USA AM stations were copied well in the car with just a super-regen RX and a base loaded whip.

In the past I have well exceeded DXCC with 10W SSB on 10m with low dipoles.

Homemade trifle - NOT amateur radio

My wife likes to make homemade trifle at Christmas as shown in the photo. 

They always taste delicious.

Village houses - NOT amateur radio

We have lots of different house styles in our village as the photo shows. 

Some houses go back many centuries and some were built this year. One old house dates to the 1100s I think.

Muddy walk - NOT amateur radio

We have just got back from a walk. It was very muddy! Part of the walk is through a wood planted for the millennium making the trees about 20 years old. 

I don't get tired walking, just being giddy all the time: it feels like I am always about to fall: this exhausts me.

10m FT8 RX

It is now 1013z. A short while ago I turned on my 10m FT8 gear using the FT817ND at the tiny indoor loop antenna. So far 24 stations spotted here on RX. Winter Es?

UPDATE 1623z:  79 Europeans spotted. Good. 

UPDATE 1724z:  88 stations spotted on 10m FT8 RX.   Unless there are surprises I expect this is it for the day. Still, this is good for 10m in winter at this part of the solar cycle.

UPDATE 2047z:  QRT.  95 stations spotted today on 10m FT8 RX.

Morons? - NOT amateur radio

This cartoon appeared on Facebook earlier. No idea who the moron could be or where the cartoon originated  😉. 

IC-705 warranty again

It appears that ICOM Australia offers a 5 year warranty if you ask whereas the standard UK ICOM warranty is just 2 years. If all UK dealers offered a 5 year ICOM underwritten warranty this might make buying decisions easier.

Snowdrops - NOT amateur radio

The photo shows the snowdrops coming out in our village. They are starting to appear now.

20m FT8 RX

This morning, I am on 20m FT8 RX with the FT817ND and the indoor loop. The gear was turned on at about 0815z.    It is now 0926z. So far today, 257 stations have been spotted already.

UPDATE 1046z: 432 stations spotted so far.

Stations spotted today at 1749z
UPDATE 1749z: 
1055 stations spotted today. At some point I may QSY to 2m FT8. All this with just the tiny loop indoors - and it cannot be that good on 20m as it is so small!

UPDATE 1929z:  1117 stations spotted so far. Latest is a South African.

UPDATE 2215z:  QRT. 1152 stations spotted today.

472kHz (630m) WSPR

At the moment I have not tried 472kHz (630m) WSPR TX for a while as I need to replace the wire in my earth-electrode "antenna". In past winters I have had lots of fun overnight with low ERP WSPR. I really should try again during January, February and March.

I still have a quiet noise floor on 472kHz WSPR RX. With AM on 160m, 80, and 40m, the noise floor is S8. WSPR being a narrow-band mode seems to do much better.

The magic of Christmas - NOT amateur radio

As mentioned in an earlier post today, Christmas can be a magical time for children. 

These are some of our grandchildren, and my wife, with some of their presents.

2m FT8 QRP with 2.5W and the big-wheel omni (Christmas)

Whilst Christmas is going on I am on 2m FT8 using 2.5W and the big-wheel omni antenna. So far today I have been spotted by 9 stations with the furthermost being G7RAU (461km) on 2m FT8 TX.  On 2m FT8 RX just a couple of Gs spotted. It is now 1045z.

UPDATE 1853z: 15 stations have spotted my QRP on TX and I have spotted 12 stations on RX with the furthermost DL6YBF (471km). As most spots of me are G and near France, these could be flat band tropo.

UPDATE 2220z: QRT.

Christmas Day - NOT amateur radio

Christmas can be a magical time for children. 

As an old man, I find Christmas hard. It is a time when we are expected to be happy, whereas I find everything amplified and pain harder to take. To me, I am glad when it is all over. 

This year is particularly hard with Covid-19 and many unable to meet loved ones and give them a hug. Next year things should be more normal. I hope so. In the next few months we have some hard times ahead. Then we should start to see the light.

Whatever your situation I wish you a happy Christmas. 

2m and 70cm activity contest results

Both the 2m and 70cm activity contest results, run every month on Tuesday evenings and organised by the RSGB, have been published. 

These show very credible scores in the low power (AL) sections, considering I usually stay on for under an hour and just use a 2m big-wheel omni antenna. No beams or rotators here!

See the RSGB contest website for details.

Sunspots - Friday December 25th 2020 (Christmas Day)

Solar flux is 88 and the SSN 25.  A=8 and K=0.  These figures were correct at 2245z Christmas Day.

Gecophone crystal set

When I retired in 2008 I was bought a Gecophone crystal set as a leaving present. This is almost 100 years old and still works.

It is in a polished wooden case and looks magnificent. They don't make things like this nowadays.

BREXIT deal done - NOT amateur radio

So, a deal has (eventually) been done between the EU and the UK. No doubt in the days ahead we will hear the details. I expect, and hope, that both sides compromised and came away feeling the deal was good for all. 

In the 2016 referendum I voted "remain", although I do appreciate that the EU can be protectionist and slow. Whilst we in the UK have vaccinated 500,000 people against Covid-19 the EU has not even started! I can understand the UK does not want to be burdened. On the other hand, the EU has been a power for good.

In my heart I expected a last minute deal: a deal is in the interests of all and there was a degree of brinkmanship to see who would blink first.

Online carols - NOT amateur radio

My wife took part in an online carol service with the Run by Singers with people from all over the world. Great. It is so good to think that all over the world people were taking part.

It is available on YouTube, but perhaps not yet. 

Sunny walk - NOT amateur radio

This morning it was very cold and crisp with a stiff northerly breeze. 

We did a walk around the village. The boat in the photo was seen at one point. You can just see the 2 ducks.

Often on this walk we see Muntjac deer, but none today.

Croatian 60m 100mW beacon

This may be worth listening for.   9A5ADI/B is a beacon on 5288.8MHz sending 100mW CW from Croatia (JN95).

2m FT8 QRP overnight and daytime December 24th

By accident, I left my 2m FT8 QRP station running overnight. I meant to turn it off. No more spots since last night of my QRP signal.  Staying on overnight is not worth it.  When we go for a walk shortly, I shall be RX only on 2m FT8. As usual, still using 2.5W and the big-wheel omni antenna.

UPDATE 1520z:  Since before lunch I have been on TX as well as RX. So far today I have been spotted by 14 stations with the furthermost being a spot by DF0MU (475km). If you want DX at any time, try 2m FT8.  Interestingly, 13 stations in just 2 countries spotted on 2m FT8 RX. I get the impression more people are monitoring and not transmitting.

Birthday breakfast yesterday - NOT amateur radio

As reported, my birthday was yesterday. The photo shows me having breakfast yesterday.

It was a cooked breakfast with fruit.

Austria gets 60m and 630m

Southgate News reports that Austrian amateurs will have access to these bands.

2m FT8 QRP (Wednesday)

As 15m has been quiet for a while I QSYed to 2m FT8 QRP at 1800z using the usual 2.5W and the big-wheel omni antenna.  At the moment (1805z) 4 stations have spotted me on TX and I have spotted nobody yet on RX.

UPDATE 1945z: 7 stations in 2 countries have spotted my QRP on TX and I have spotted 3 stations in 2 countries on RX.

15m FT8

It is now 1005z and I have just turned on 15m FT8 RX. So far,  5 stations spotted on RX with the indoor loop and FT817ND.

UPDATE 1207z:  37 stations spotted so far with the furthermost 9K2OW (4639km) in Kuwait.

UPDATE 1352z: 76 stations in 5 continents spotted so far on 15m FT8 RX today. Furthermost is HC1DAZ (9256km) in South America.

UPDATE 1651z:  Now 136 stations spotted.
