Return to 472kHz WSPR

For the first time in many months I have returned to 472kHz WSPR using 10mW ERP from the earth-electrode "antenna" in the ground using my transverter driven with the FT817ND. G1GKN (99km) is a good signal. So far, I have only been copied by G0VQH (15km).

UPDATE 2015z: Best DX on 472kHz WSPR RX is DL7NN (873km).

UPDATE 2120z: The following unique stations have been spotted:

Best DX on 472kHz WSPR RX is LA8AV (1035km).

UPDATE 2138z: Although I am not that hopeful, I shall stop on 472kHz WSPR overnight. It is still summer and the noise levels will be high, preventing many stations from copying my QRPP signal.

Thunder and Lightning

At the moment we have thunder and lightning, so everything in the shack has been disconnected for now.

6m FT8

A recent 6m FT8 CQ was spotted by 6 stations with best DX being OZ9QV (861km). On RX not a single spot yet.

Stations spotted so far today 

on 6m FT8 RX (to 1252z)

UPDATE 1156z: Plenty of stations (64) now coming through, many by Es, today on 6m FT8 RX.

UPDATE 1252z: 74 stations from all over Europe spotted in the last 12 hours in 6m FT8 RX. Who said the Es season is over?

UPDATE  1610z: When the storms "stopped play" 96 stations spotted with best DX on 6m FT8 RX being 4X1SK (3566km) in Israel.

UPDATE 1705z: The storm seems to have moved westwards, so everything was reconnected. I called CQ on 6m FT8 and worked a YO2. The best DX of me on 6m FT8 TX was 9H1PI (2130km) on Malta. Now 125 stations spotted here today in the last 12 hours on 6m FT8 RX with the V2000 vertical omni antenna.

UPDATE 2020z: When I eventually "pulled the plug" because of storms (again) 146 stations were spotted on 6m FT8 RX. I have since QSYed to MF WSPR.

The arrow of time - NOT amateur radio

One of the things we take for granted is that the future is the future and the past is the past. Of course time itself could be an illusion. Our limited brains may make this hard to conceive.

If I recall my quantum mechanics correctly, everything can be represented as a wave function in all time and all space. Tunnel diodes only work on the basis of this "probabilistic" world view. They work!

Codar AT5 TX

How times change!

When I was first interested in the hobby we had horrendous noise at the top of 160m from Loran. In recent years we have noise all over the band from switch mode PSUs and other man made noise sources.

In the late 1960s 160m was the main mobile band, using AM of course. A popular TX was the AT5 paired with a T28 RX. The AT5 covered 160m and 80m and produced about 12W output. In its day it was a good radio from the car or at the home QTH. I always wanted one.

6m MSK144 RX

Overnight, I was monitoring the 6m MS "watering hole" on 50.280MHz MSK144. Certainly now and maybe for some time the Internet has been off, so reports to PSKreporter will not have got through.

UPDATE 0615z: As I was concerned that my internet connection was off, I checked the PC to see what 6m MSK144 signals were received overnight - nothing! This makes me wonder if something was wrong .

Oscar 100 - is activity increasing?

Last night at about 2022z I took a peak at the activity on the wideband transponder of Oscar 100, the geosynchronous amateur satellite. Perhaps I was lucky but there were 10 active SSB stations, most in QSOs. Now, maybe I chanced on a good time, but this is the busiest I have ever seen on Oscar 100.

Chester town crier - NOT amateur radio

Last week we were in Chester.

In the photo, the town crier is in good voice. I think he makes a good tourist attraction these days.

6m FT8

As I am home again, I am on 6m FT8. Only 2 stations spotted here so far on 6m FT8 RX (Denmark and Switzerland), but I got 9 spots of my CQ call on 6m FT8 TX with the best being OY1OF (1163km) in the Faroe Is.

UPDATE 1600z: With just 4 stations spotted I think many are now leaving 6m thinking the Es season has ended.

UPDATE 1633z: In the last 25 minutes I called CQ on 6m FT8 TX. 25 spots from all over Europe (as the map shows) indicating the Es season is far from over. No QSOs resulted, which tells me many are still monitoring, but fewer are on TX.

UPDATE 1856z: Another recent 6m FT8 TX CQ call was spotted by 12 stations.

UPDATE 2012z: A recent 6m FT8 TX CQ was spotted by 6 stations right across Europe. I am convinced that many who would be on TX think the Es season is over.

Chester - NOT amateur radio

Chester is a fine city not far from Liverpool, UK.

It has many sorts of architecture and the old centre is quite compact, so easy to walk around.

It is enclosed by old city walls that one can walk around. It also has a fine cathedral.

Something for the weekend

Every weekend MLS, a UK dealer, does a promotion of some kind. This weekend, they are focusing on Yaesu.  As far as I can tell, there are no special discounts. Check their website for more details.

Perseids Meteor Shower

Southgate News reports on the Perseids Meteor Shower that reaches its peak soon.

DXing with crystal sets

Shortwave broadcasting has changed a lot in recent years as more switch to the internet to get their message across. The internet is lower cost and generally much higher quality.

Having said that you may be amazed just what can be heard on a humble crystal set on HF. A few years ago I had quite a bit of success.

There are bigger schematics and photos on the webpage below. Remember all the power comes from the TX end.

UK power outages - NOT amateur radio

All the public pronouncements have been that the recent UK power outages are from unexpected generator failures.

I hope this is the truth and that this isn't as a result of some malign foreign power or terrorists acting with ill intent on the software.  It seems odd (to me) that we have a major computer failure at a major airline a few days ago and now this. It will be interesting to see if a government COBRA meeting is held.

Perhaps I am being paranoid.

Most photographed clock in England? - NOT amateur radio

As Big Ben is shrouded in scaffolding, this clock in Chester is supposed to be the most photographed clock in the country.

Liverpool dockside - NOT amateur radio

In recent years Liverpool dockside has been made into a very attractive area. When I was there as a student in the late 1960s it was very run down. The photo shows the skyline today.

Life after death? - NOT amateur radio

Sorry to bring this up again.

When we die our brain cells die and logically we cease to exist any more.

However, we know so little about everything we experience that there is some doubt. The simple answer is no-one can be really sure. In some ways it is perhaps better that death is the end.

A blast from the past on 2m SSB/CW

Back in the 1970s, in the early days of 2m SSB, the most popular rig was the Belcom Liner-2.

Hot on its heals a few years later came the IC202 from ICOM. I had one of these and even used it on 10m with a Microwave Modules transverter. With internal batteries it could be used portable and even handheld. Some great DX was worked with it on 2m SSB and on 10m SSB using that transverter.

See https://sites.google.com/site/g3xbmqrp3/vuhf/ic202

Roses - NOT amateur radio

These fine roses are in a neighbour's drive. They are keen gardeners. They have a big garden that needs a lot of attention. The hedges alone must be 200m long. It's a good job they enjoy it!

First FT8 160m QSO with new rig

160m FT8 log 
(stations that spotted me)

Earlier I worked G0BLB (211km) in IO81 in daylight on 160m FT8. This my first 160m QSO with the new radio. So, I think I have solved the mystery with the rig on HF and FT8. This was on the earth-electrode "antenna" in the ground. Hopefully after dark some Europeans will be spotted.

UPDATE 2030z: My brief 160m FT8 CQ to the earth-electrode "antenna" in the ground resulted in 9 spots. The best was a spot by DJ9PC (821km). On RX my best spot on 160m FT8 RX is R2AL (2417km) near Moscow.

160m FT8 spots this 

evening of my CQ calls

UPDATE 2102z: A recent 160m FT8 CQ call (no QSOs resulted) was spotted by 15 stations with the best spot being by OL7M (1126km).

160m FT8 tonight

All being well, I intend to be on 160m FT8 this evening. I will be using the earth-electrode "antenna" in the ground with about 10W from the FT991A. As for the ERP, probably low mW!

On WSPR this (with even lower power) has got me to Sweden with this "antenna".

The 160m FT8 frequency is 1.840MHz USB digital. I have not tried FT8 yet on 160m.

UPDATE 1625z: I put out a couple of CQ calls, but no spots. I guess this is far too early as it will be light for hours yet.

FT8 issue fixed?

Yesterday I reported that I was struggling on FT8 RX on 20m, and other bands like 70cm RX. I knew the PC settings were right as these worked on 6m and 2m, so the issue had to be with the rig settings.

It appeared that the bandwidth settings on bands other than 6m and 2m was 500Hz. Setting this to 3000Hz seems to have fixed the issues. I am now receiving stations on 20m FT8 on 14.074MHz USB digital with the loop on the back of the rig. I have no idea why these settings were as they were. Maybe I can try 160m FT8 with the earth-electrode "antenna" tonight?

On TX with 8W I have not had any spots yet, but at least there are now RX spots from all over Europe on just the tiny loop.

UPDATE 1342z: Best DX on the tiny loop on 20m FT8 RX is RA1OD (2920km). Another CQ call got no spots.

80m QRP - the XBM80-2 transceiver

About 7 years ago I designed this ultra-simple QRP transceiver for 80m. It managed some local QSOs. These days, following my stroke, designing and building things is hard.

There is a YouTube video too shown here.
