6m FT8 yesterday

On TX 142 stations in Europe spotted me and 303 stations spotted here.

Sunspots - Sunday July 19th 2020

Solar flux is 68 and the SSN 0. A=4 and K=0. Still poor.

Party - NOT amateur radio

As it was someone's special birthday we had a socially distanced party on our green as the photo shows.

10m FT8 (500mW and the indoor loop)

Until about 1130z, I am on 10m WSPR. Using the indoor loop, I shall turn things off to prevent the risk of RF burns to the grandchildren who are arriving this afternoon.  As yet, no spots received. It has been on for about an hour. It is now 1037z.

New ICOM IC-705 video

Southgate News has a piece linking to the new ICOM video about the SDR based ICOM IC-705 QRP rig.

Wireless charging

In the last few years things appear to have moved on with wireless charging now available at very competitive prices. I assume the device has to have a way of receiving the inductive field. Is that what they mean by "QI compatible"?

I expect some amateur radio manufacturer will catch on so that some 2m and 70cm handhelds can be charged by simply placing the rig on a charging pad. I would expect this to be a flexible PCB coil within the battery. They could even reduce bill of material (BOM) costs by building the cells within the radio body and not even selling a charger. I expect either a Chinese manufacturer or ICOM will be first. You can imagine the Yaesu engineers saying "that's a good idea, why didn't we think of that?".

Dog - NOT amateur radio

In the next road is a dog that wails whenever a police siren sounds: we hear the police car, wait a few moments, then we hear the dog! It must think it is a mate.

6m FT8

Since about 0750z, I have been active on 6m FT8 with 10W and the V2000 vertical omni antenna. 16 European spots of me already. Just a single G spotted on RX and no QSOs. It is now 0801z.

UPDATE 0837z: 5 stations now spotted on RX and 24 stations have spotted me. No QSOs yet today.

Cornfield walk - NOT amateur radio

One of our favourite walks takes us across this cornfield. At the moment the corn is ripening.

Sunspots - Saturday July 18th 2020

Solar flux is 68 and the SSN 0. A=4 and K=1.

Sunflower - NOT amateur radio

On our walk this morning we saw our first sunflower out. Ideal today with sunshine all day. It was a nice day all day - the best this month.

10m FT8

It is now 0750z. For about an hour I have been on 10m FT8 with the tiny indoor loop antenna and 5W.  So far 15 stations spotted and 1 spot of me.

UPDATE 1057z: 15 spots of me so far today.

Getting older - NOT amateur radio

At 71 and a few years longer lived than my dad and granddad, I guess it is fairly natural to contemplate mortality.

Years ago, life seemed endless. These days I am more aware just how finite life is. I suppose I could live another 30 years or I could die today. At one time I seemed invincible whereas I now feel in my last years. More of my friends have died.

Generally I am a "glass half full" kind of person, so I still think long term.

Sunspots - Friday July 17th 2020

Solar flux is 69 and the SSN 0. A=4 and K=1.

Finningley rally postponed

Today I heard about another postponed rally. As before, this is as I received it, so the background may make it hard to read on some screens. The summary is the Finningley Rally has been postponed.

Yet more - NOT amateur radio

It seems that every space in our village is being used to erect new houses. These are not houses for the people that really need them, but large homes for the well healed that work in nearby Cambridge. I guess these maximise profits for the builders.

The latest are being built on what was a field. I have no idea how many homes are being built, but I would expect at least 4. It would be nice to be a "fly on the wall" to see what was the village was like years ago. The trouble is that when new places go up you cannot remember what was there before!

10m FT8 (5W to indoor loop)

It is now 0912z. Since about 0900z, I have been on 10m FT8. A couple of European spots of my 5W already received and the best DX on 10m FT8 RX is JA9CVH (8770km) in Japan.

The loop 

This tiny indoor loop continues to amaze me. It is just fixed to a chair in the downstairs shack yet I continue to get fantastic results.

UPDATE 1904z: 110 stations copied on 10m FT8 RX and 26 stations have spotted my 5W (or less) on 10m FT8 TX today. In some situations I was using 3W. Several QSOs had (all within Europe).

UPDATE 2106z:  130 stations spotted on RX and 30 stations spotted my 5W or less 10m FT8 TX. Several QSOs, all European via Es.

Me in 1968 - NOT amateur radio

One of my Facebook memories today was this photo of me in 1968 when I still had lots of hair!

World population - NOT amateur radio

According to recent research the world population is expected to peak mid century and then fall dramatically as the birth rate nose dives. One consequence will be more old people and fewer youngsters. The concern is taxes and care of an ageing population.

It probably means more migration and different employment opportunities. From a world resources view point I think this is good news: more food to go around and less environmental damage.

QRP transceiver ideas in RSGB RadCom

FETer 80m CW transceiver

It was pleasing to see my article in the August 2020 edition of RadCom on ultra simple QRP transceiver ideas. There are a couple of circuit ideas, one for 80m and one for 10m. 

These are extremely simple circuits that would make nice wet weekend lockdown projects. One uses just a single FET and the other just 2 transistors. Remember, these are complete transceivers!

As I state in the article, please don't be afraid to experiment. My hope is that, like me, you adapt the circuits to find what works best for you. The circuits are simple and like all simple rigs, they are compromises.

Both work and have been used on the air. More details are on my main website and YouTube channel.
