ICOM IC9700 (VHF/UHF/23cms)

This rig was announced in Japan in September. It will replace the IC910 and cover 2m, 70cm and 23cm. I have no idea about price. It looks like the same architecture as the IC7300. At the right price this looks an attractive radio, but I expect it will be too expensive. MLS is already taking £100 deposits.

Another rally in the UK

22 OCTOBER 2017 : GALASHIELS RALLY
The Volunteer Hall, Galashiels TD1 3JX

630m WSPR overnight

You may remember that I found the 2 radials across the lawn and an additional local ground made no difference and may have made my ERP lower. This surprised me.

Last night my 10mW ERP was spotted by 11 unique stations on 630m WSPR with best DX a spot from LA3EQ/MW (769km) and I spotted 10 unique stations on 630m WSPR.  This is, I think, the first time more stations spotted me than I spotted others.

Sunspots - Friday October 20th 2017

Solar flux is 74 today. Sunspot number is again zero. A=12  and K=2.

10m FT8 RX

After overnight on 630m WSPR transceive, I am again on 10m FT8 RX. Best DX spotted is 4Z5ML (3571km) in Israel. I assume this is F2 propagation. F1DLZ (362km) also copied in northern France which might be aircraft reflection.

I am still using WSJT-X V1.8.0 rc2. I really must upgrade later.

UPDATE 1105z: Lots of 10m Europeans and lots of DX on 10m FT8 today, despite a sunspot count of zero again. As they say, "FT8 cuts the mustard". Very impressive.

UPDATE 1312z:  Now spotting Mauritius - 3B8CW (9751km). Today has been a very good day on 10m FT8. I expect South Africa next, then South America.

UPDATE 1428z: There is no doubt that today is the very best day on 10m FT8 this autumn. So far, 9 North Americans spotted here as well as every continent except Antarctica.

UPDATE 1716z: Best DX today on 10m FT8 was LU8XAF (13413km) in southern Argentina.

19 Oct 2017

Moved to 630m WSPR

In the last 30 minutes I have moved from 10m FT8 RX to 630m WSPR transceive (10mW ERP). Quite a few spots of my signal on each transmission.

10m FT8 today

Already, I have spotted stations in 5 continents on 10m FT8 today: Australasia, Asia, Africa, Europe and South America. This with a low end-fed wire antenna - no big towers and beams here, HI.  I suspect there will be a few more South Americans in the next few hours. And all this is on a day with zero sunspots and when 10m is supposed to be "dead".

At the moment I am still using WSJT-X V1.8.0 rc2. There is a later version (rc3) too that I must download and use.

Many desert 10m. Stick with it, as you may be very surprised.

This autumn, 6 continents have been spotted on 10m FT8. A great band and FT8 is proving to be a great mode.

Catalonia - NOT amateur radio

Catalonia is quite a rich part of Spain. Spain cannot afford for it to break-away. It is hard to see how the EU would handle this. If Catalonia goes, surely the Basques will want to follow? This would leave Spain in a right mess. By comparison, BREXIT is quite simple and clear. Personally, I think this will grow into the EU crisis of 2018.

My memory - NOT amateur radio

I mentioned earlier that I go to a series of lectures on Samuel Pepys in Cambridge each Wednesday. So far, there have been 2. Let me recount an odd story.

The first talk was Wednesday last week. I travelled into Cambridge on the service bus that leaves at 9.49am. This should arrive at about 10.43am. It is a 10 minute walk from where the bus stops to where they hold the lectures. The lectures are from 11am -12noon.

In my mind I have a very clear picture of being the very first there and helping to set out chairs and the main table. I sat at the same spot yesterday, furthermost from the door. This memory is very, very, clear. However, to get in very early would have been impossible using this bus. I would have arrived shortly before the lecture started. I have absolutely no memory of arriving "just in time". I am still deeply puzzled: was this a dream? Only if I suddenly have a flash-back will this mystery be solved. In the meantime, I cannot be sure what is a dream and what is reality!

Some would say, "old age". Others might say, "your stroke". The truth is I just do not know what happened a week ago.

Autumn - NOT amateur radio

You can tell it's autumn! This was our nearest garden centre this morning.

At the other garden centre they had lots of Christmas things on sale. Well, it is October and profits are profits. Personally I think Christmas things should only be allowed for sale in December, but I am a grumpy old man!

Rain - NOT amateur radio

Yesterday it rained.

This is a view of Rose Crescent, Cambridge, looking towards the Market Square. If it rains in Cambridge, we are quite unlucky as rainy days are quite rare. We get them, but it rains far less in the SE of the UK than in the west.

10m FT8

Since breakfast, I have been on 10m FT8. As yet, no spots.

UPDATE 1124z: Several DX stations to the east spotted on 10m FT8 including VK9VKL (11970km) on Christmas Island. He appears to have been widely spotted, so he looks genuine. This is my first VK this autumn.

Food - NOT amateur radio

Every Tuesday and Wednesday I travel into Cambridge for University of the Third Age lectures.

On Tuesdays it is, "Weather and Climate" and on Wednesdays, "Samuel Pepys". We are very lucky in Cambridge having a huge variety of courses.

Afterwards, my wife joined me for lunch.

630m WSPR overnight

Spots of my 10mW 630m WSPR overnight
For last night's test I removed the radials across the lawn (2) and a local ground quite close to the shack. If anything results were better! On TX I was spotted by 9 unique stations (10mW ERP) and on RX I spotted 12 unique stations. I was spotted in Wales for the first time this autumn on 630m and G0KTN was another new one this season. My conclusion is, in my case, the radials made no difference and actually may have made things worse. I guess this says my ground is actually more effective than I thought. The actual antenna needs improving if I am to up my ERP.

Sunspots - Thursday October 19th 2017

Solar flux is 72 today and the sunspot number zero.  A=5 and K=3.

18 Oct 2017

Now on 630m WSPR (no radials)

At 1750z, I switched to 630m without my radials and additional ground outside of the shack. Antenna current is the same.

UPDATE 1804z: Initial indications are that the radials made no difference at all. This suggests my ground connection was already pretty good and that only a better antenna would make a real difference to my ERP.

Switched to 10m FT8 RX

A few minutes ago, I switched from 10m WSPR TX to 10m FT8 RX. As yet, no spots. Later, I shall go onto 630m WSPR having removed the radials and additional ground, that were of questionable benefit.

UPDATE 1750z:  No spots. Now switched to 630m WSPR.

UK pound versus euro exchange rate - NOT amateur radio

Some time ago I predicted that the pound would appreciate against the euro before the year end. Well, it is mid October and, if anything, it is losing value! I guess BREXIT uncertainty is the main reason. Fundamentally, the euro still has issues, although I think my end of year may be out.

10m WSPR

As the 10m antenna was not being used, I have been on 10m WSPR TX (500mW) since just after breakfast. OZ9QV (864km) is the only spot so far. This was at 1322z.

630m WSPR - not convinced of improvements

Overnight, I was on 630m WSPR (10mW ERP). In all, I gave out spots to 12 unique stations and received spots from 6 unique stations. I am not convinced that adding my 2 radials across the lawn and an additional earth near the shack has made any improvements. This suggests my mains ground is actually quite good.

6m FT8 RX

Since breakfast, I have been in 6m FT8 RX again. No spots as yet. Yesterday surprised me with several UK spots plus a German on 6m.

UPDATE 1542z: No 6m spots all day.

Sunspots - Wednesday October 18th 2017

Solar flux is 72 today and the sunspot number again zero. A=6 and K=2.

17 Oct 2017

Back on 630m WSPR

About 5 minutes ago I returned to 630m WSPR. My ERP is about 10mW. I am interested to know if my extra earth and radials help. Last night was inconclusive.

UPDATE 2122z: Well, things are still inconclusive! I am getting a similar number of spots of my 630m WSPR signal as I am giving out. What does that tell me?

10m WSPR TX (500mW)

About 30 minutes ago I turned on the 500mW 10m WSPR beacon. As yet, no spots.

UPDATE 1304z: Still no spots.

6m FT8

A few minutes ago, I switched to 6m FT8. As the 10m antenna is unused, I may go on 10m WSPR TX at the same time.

UPDATE 1002z: No spots.

UPDATE 1300z: 3 UK spots so far on 6m FT8.  Best DX is MW0LGE (229km) in South Wales. By the way, this is with WSJT-X V1.8.0 rc2 and a V2000 vertical omni.

UPDATE 1750z: Best 6m FT8 DX today is DK1QG (645km) near the Danish border.

Sunspots - Tuesday October 17th 2017

Solar flux is 70 today and the sunspot number remains 12.  A=9 and K=2.

10m FT8 RX and FT8 rc3

As usual, I switched to 10m FT8 RX at breakfast. No spots as yet. Apparently WSJT-X v1.8.0 rc2 has been out for a month and now rc3 is available. There may be a proper release of V1.8 as early as next week. K1JT has been busy with neutron stars!

I may try 6m FT8 RX later. 10m FT8 seems to work a dream.

Last night on 630m WSPR

Overnight I was keen to see if the addition of 2 radials and an additional ground outside the shack improved my results on 630m WSPR. Well, I am not sure. Overall I got spots from 10 unique stations (my highest yet) and I spotted 10 unique stations. Clearly some new stations copied me, but I am not sure if this is my system or just that they have recently returned to 630m. Certainly my reports of "regulars" on RX seem no better. At the moment, I am doubtful of any improvement, although it needs a few more nights to get a better picture.

16 Oct 2017

630m "improvements"

My 630m radiating system has been altered with a couple of radials across the grass and an additional ground outside the shack. Measured antenna current is no higher, which surprised me. This evening and overnight we'll see if there are any improvements in reality.

USA on 10m FT8

Not long ago, WB2REM (7017km) in Florida was spotted on 10m FT8. There are South Americans and the Falkland Is coming through. Earlier Burkina Faso and South Africa were spotted on 10m FT8.

630m WSPR overnight

The big question for me was, "did the additional earth make any difference?". Well, with 6 spots of my QRPP 630m WSPR I think the answer is, " yes probably". It may have only raised the ERP a dB or so, but this could be the difference between being detected and not.

The next thing to try is some better grounds near the shack and some radials down the garden that can be rolled up when grass cutting.

UPDATE 1220z: 13 unique stations spotted on 630m WSPR last night.

10m FT8

Since breakfast, I have been on 10m FT8 RX. So far, the only spot was of PA0O (440km) near Groningen about 30 minutes ago. Aircraft reflection?

UPDATE 1210z: Lots of Europeans spotted on 10m FT8 rc2. I am told that WSJT-X V1.8.0 rc3 will be available soon.

UPDATE 1246z:  At the last count, 20 unique Europeans spotted on 10m FT8. This mode really is good.

UPDATE 1327z: XT2AW (4446km) in Burkina Faso (W.Africa) is currently the most distant station spotted today on 10m FT8. I have lost count of the Europeans! Maybe tomorrow I should give 6m a go on FT8?

UPDATE 1356z: Now the best DX is ZS2CR (9893km) in S.Africa.

Sunspots - Monday October 16th 2017

At last some sunspots!

Solar flux is 70 and the sunspot number 12. A=26 and K=3.

15 Oct 2017

Switched to 630m WSPR

Even though 10m FT8 is still good, I have switched to 630m WSPR. So far just G4GIR (53km) spotted at -14dB S/N. I am keen to see if I can see any differences since I changed the grounding.

UPDATE  1838z:  Initial indications are things are better. Already I have had 4 unique spots of my QRPP 630m WSPR signal.

630m ground improvements

Just before lunch I made a "temporary" fix to my earth-electrode "antenna". I have still to solder the joints. My secondary antenna current went from 17uA to 22uA. It remains to be seen if this makes any difference in real use. I'll try it tonight.

UPDATE 1304z:  I have now soldered the joints, so the repair is permanent.

UPDATE  1530z: Any slight improvement might be seen tonight. I am not expecting much.

North America (and more) on 10m FT8

A few minutes ago VO1NE (3898km) was spotted on 10m FT8. This is my first North American spotted on 10m this autumn. WSJT-X V1.8.0 rc2 was loaded this morning.

UPDATE 1238z: Not sure if WSJT-X V1.8.0 rc2 made a difference, but lots of 10m FT8 spots from Europe. It is supposed to be more sensitive.

UPDATE 1305z: I notice a spot from an FR5 that was not uploaded to PSK Reporter Maps.

UPDAT.E 1358z: First South American on 10m FT8 today was PY5JAP (9903km) a few minutes ago.

UPDATE 1532z: 14 South Americans spotted on 10m FT8 so far.

UPDATE 1712z: Now over 30 unique 10m FT8 spots of South Americans.

UPDATE 1830z: 41 unique 10m FT8 spots of South Americans today when I went QRT on 10m.

630m WSPR overnight

In all 3 unique stations copied my QRPP WSPR signal (about 10mW ERP) overnight.

I managed to spot 10 unique stations including a couple of LAs. Best DX spotted overnight on 630m WSPR was IW4DXW (1190km).

Sunspots - Sunday October 15th 2017

Solar flux is 68 today and the sunspot number remains zero. A= 31 and K=5.
