Rain - NOT amateur radio
A few moments ago we had rain. It has been thundering. The last week has unbearably hot and humid by day and night.
10m FT8
It is now 0900z. A few moment ago, my 10m FT8 gear was turned on for a little while (4W, indoor loop). Already 3 spots of me by Es. On 10m FT8 RX nothing spotted here yet.

70cm activity contest last night
As you may recall, I entered the RSGB organised activity contest on 70cm last night. As I have no suitable antenna, I use my 2m big-wheel omni and stay on for less than an hour because of my poor voice. In all, 6 stations were worked , all SSB, as the map shows.
Eat out to help out - NOT amateur radio
During August you can get up to £10 per person off meals and soft drinks at some participating pubs and restaurants on certain days.
We ate out this lunchtime and had fine meals (hallumi starter and swordfish main) including wine and sparkling water for £22!!

Oscar 100 (geosynchronous)
As usual, I took my periodic peek at the narrowband transponder. When I did this it was 1053z. This is midweek and about mid day in Europe. Only 2-3 QSOs were active, confirming to me that it is not busy. The most I have ever seen is about 8 QSOs. If it was busy, it could hold many more.

10m FT8
Using 4W to the indoor loop, I am currently on 10m FT8. It is now 0830z. So far today, 10 stations have already spotted me.
UPDATE 0920z: 23 stations have spotted me so far this morning and 19 stations in 3 continents spotted on 10m FT8. An outside antenna I think should be better? I guess 6dB (maybe more) could make quite a difference on weaker signals that might not be in audible on the indoor loop. For Es, the loop is probably is good enough most of the time but on marginal F2 or TEP I guess this loss could matter.
UPDATE 1500z: Since returning from our meal out 39 stations have spotted me already. 11 stations spotted here so far this afternoon.

WSJT-X V2.2.2
Well over a month late, I have upgraded to V2.2.2. I did try upgrading some weeks ago , but it said I was missing a dll, so I stuck with the older version. Today it installed fine. Not sure if this was Windows is or WSJT-X. Anyway it is now installed and working fine.

10m antenna?
As many know, the outside antenna that I used on 10m packed up so I have been using my indoor loop successfully for the last few months.
In the next few months I hope to re-elect an antenna for 10m. In the past this would have been trivial, but sadly not anymore. A couple of people have kindly offered me help, but with Covid-19 I am reluctant to ask them. My thoughts are what could be erected with the least effort. I guess this either a wire dipole or inverted vee. My own Homebase-10 would be good, but the trouble would be making it now.

Thunderstorms? - NOT amateur radio
The last few days have been very hot and humid. It has been almost unbearable. Later, we may have thunderstorms.

UPDATE 1548z: Although the nearest thunderstorms are about 100km away, i think there are distant rumbles.

70cm activity contest
Tonight is the RSGB organised 70cm activity contest (UKAC). This starts at 1900z.
UPDATE 2205z: In the end I managed 45 minutes with the 10W and 2m big-wheel omni antenna. 6 contacts. My best DX has still not been worked out although it is probably G4CLA (105km).

PSKreporter and 8m + 5m
Today I learned that PSKreporter now supports 8m and 5m. 8m is just beginning to become active in some countries.
Old bank - NOT amateur radio
The only bank in our village closed 2.5 years ago. Today it looks like it is being gutted. I have no idea what is going on.

Rear garden in August - NOT amateur radio
The photo shows our rear garden in August.
We get most colour in Spring and about now. Our grass is suffering in the heat. They used to say, "don't water the grass as it will recover".
Until recently, I followed this advice. Then in 2018 a third of my front lawn just died and never recovered. Since then, I have watering particularly dry patches for almost an hour most dry nights. Hopefully my lawns will recover in the autumn when the dew returns.

More damselflies - NOT amateur radio
Yesterday, I showed a photo of two damselflies. Today, here are two mating. This was again at Cavenham Heath yesterday.

Amateur VLF
There is a myth that VLF antennas are big. For RX they can be very very small!! So, for RX only, amateur VLF is remarkably accessible.
For TX high power and big antennas certainly help. DK7FC has had some excellent results with long distances using earth probe antennas. These don't require very huge loading coils.
VLF amateur work requires dedication, although VLF earth-mode can give good results with quite simple kit. This is certainly one of the frontiers ripe for experiments.

Stone curlews - NOT amateur radio
Stone curlews (see the poor photo) are rare in the UK. Cavenham Heath where we walked yesterday is one of the best places to see them. Most migrate in October. We saw 12 yesterday.

10m FT8
It is now 0811z. A few moments ago my 4W to the indoor 10m loop was turned on in the hope of some Es. 2 Es spots on RX but no spots of me yet.
UPDATE 0917z: Now 9 Es spots of me already and 16 spots on 10m FT8 RX. Promising.
UPDATE 1235z: 23 spots of my 4W 10m FT8 to the indoor loop.
UPDATE 1807z: 24 stations spotted me today. On 10m FT8 RX the best DX spotted was PU5BOY (9961km). In all, 67 stations were spotted today.

Yesterday evening on 10m FT8
Yesterday evening I swapped from 6m FT8 to 10m FT8 with about 4W to the tiny indoor loop antenna. Quite a few Es spots of me and many southern European stations spotted on RX as well as a QSO via Es
IC-705 on the ICOM Japan website
The ICOM Japan website has more on the IC-705. Under "Optional Accessories" it mentions an antenna tuner at a later date (see yesterday's post).

IC-705 auto ATU?
According to the IC-705 Facebook page, ICOM is working on an auto-ATU to match the IC-705. They hope to release it this year. This is a stand alone external unit covering 1.8 to 50MHz.
Inter S51 QSO on 8m
Apparently the first QSO between stations in Slovenia has taken place on 8m. I hope we can all join in on 8m in the near future.
Cavenham Heath - NOT amateur radio
Cavenham Heath is about 15 miles from here. It is a national nature reserve and a great place to see rare stone curlews. We saw 12 but they were about 400m away. The heather will be at its best in about 2 weeks. There were damselflies (see photo) everywhere.

Rye - NOT amateur radio
In 2012 we went to Rye in Sussex. It's a delightful place with old houses and cobbled streets. We were fitter then!

10m WSPR
Since just before lunch I have been on 10m WSPR TX with the 500mW TX beacon. As yet (1342z) no spots so far.
6m FT8
Just before lunch my 10W and V2000 sending and receiving 6m FT8 were turned on. It is now 1326z. So far, 2 stations have spotted me today and I have spotted 6.
UPDATE 1500z: 7 stations have spotted me and I have spotted 14.

Reach Village - NOT amateur radio
Reach, shown in the photo, is a sleepy village some 9 miles from Cambridge. We like walking around here. In Roman times it was an important port. It is at the northern end of a defensive earthwork.

My antennas
For 6m, 2m and 70cm vertical I use a "white stick" vertical omni called the V2000. I have probably has this for at least 15 years! It is fed with low cost, CB, 50 ohm coax. On 70cm I could gain several dB if I replaced this with half decent coax. On 2m and 70cm SSB and FT8 I normally use the 2m big-wheel omni.
On the photo, the V2000 is on the left. The big-wheel is above my head and slightly right.
Not shown are the 10m loop (in the shack) and the earth-electrode "antenna" which gives me very good results on 630m WSPR. Norway is reached most nights despite the 10mW ERP on 630m.

Different PC
Since just before lunch I swapped the shack pc to a different one. It seems to be working fine on 10m FT8.
Perseids meteor shower
Many people like to make VHF contacts in meteor showers. Modes like FT4 and FT8 should be particularly effective I think. Signals are often strong, but short lived.
I see Southgate News has a link about this.

New blog editing interface - TOTALLY CRAP!!!! - NOT amateur radio
In the end I had to revert to the old interface to edit this blog as the new interface is unusable!
Like Bas yesterday, I have sent them my feedback. If you have a blogger.com blog please send them your feedback too. The more people the better.
The old interface is fine, whereas the new is painfully slow.

Zebra? - NOT amateur radio
Earlier, we saw this horse in a field on our walk. It had a coat on with zebra stripes. I think the owner must like zebras!
10m FT8
At about 0845z my 10m FT8 gear was turned on. As usual I was running about 4W to the tiny indoor loop antenna. So far, 10 stations spotted and 8 stations spotting me.
UPDATE 1147z: Already today I have been spotted by 28 stations despite the 4W and the indoor loop. On 10m FT8 RX 38stations have been received so LWfar today. I am amazed how strongly some people are receiving me despite the low power and indoor loop.
UPDATE 1702z: Amazingly, 67 stations have so far spotted my 4W 10m FT8 to the loop antenna. On 10m FT8 RX the best DX so far today is LW2DAF (11213km) in Argentina.
UPDATE 1950z: Now QRT. 233 stations spotted today on 10m FT8 RX and 75 stations spotted me on 10m FT8 TX today.
