Return to 472kHz WSPR

Since returning to 472kHz WSPR at teatime, 6 unique spots so far received this evening.  No new stations logging me but on the whole decent reports being received. I'll probably remain on 472kHz overnight, but go QRT again on 28MHz (10m) WSPR as I think I've missed any DX for today.  Still using the earth-electrode "antenna" and about 5mW ERP (or less).
Unique 472kHz WSPR spot in first 2 hrs this evening
UPDATE 2300z:  Now 12 unique spots of my 5mW WSPR this evening with best DX report from F59706  (560km).

50MHz UKAC this evening

Starting at 2000z, the monthly UK activity contest takes place on 6m. I only have a vertical for 6m and my voice is still poor.  However, I'll come on briefly to see what I can work before my voice says stop. I may be only able to give a few points out to the locals.

10m - too late?

I turned on my 10m 500mW WSPR beacon just after 1700z, but only local G4IKZ spotting me. If the band did open to the USA I missed it today!

40m WSPR

For the last day (nearly) I have been WSPRing on 40m using about 2-2.5W from the FT817 into the low Par triband 10/20/40m end fed antenna. On 40m this is far too low, although on 10m it is probably just high enough. Despite the low height on 40m I have received 31 unique spots with best DX being K3BXO (7190km). Since about 20 minutes ago I have gone back on 472kHz (earth-electrode "antenna") and 28MHz (10m) WSPR on the Par end-fed.
Unique WSPR spots on 40m today/yesterday


Sunspots and 10m

Sunspot number has fallen again to 44 and 10m propagation is "poor". For the first time since way back last year (summer?) I have NOT been on 10m today yet, as I needed the triband antenna for some 40m WSPR tests.

BTW, in the end I have ordered a 10m President Lincoln Mk2 (V3) from Nevada Radio here in the UK. The Pixie (40m) should be finished tomorrow as I had no opportunity yesterday and today. I also need to find my small rechargeable 12v battery and charge it. I suspect 50Hz hum would be a problem on the shack PSU.

President Lincoln Mk2 (V3) - 2 year warranty period

Not only has the price of this 10m transceiver dropped to £199, but John Gordon of Nevada has confirmed that the warranty period on these transceivers is 2 years. I am seriously tempted.

Sunspots and 10m

Sunspot number today is 49 and 10m propagation is described as "poor". Despite this, my little 10m 500mW WSPR beacon was being copied in W.Australia earlier this afternoon.

10m conditions are changing

This afternoon,VK6DF (13606km) in West Australia spotted my 500mW WSPR signal at 1404z. The band opened to the USA,WB5B (8248km) but very late at 1550z.

10m conditions do seem to be changing.

UPDATE 1844z:  The last USA station to spot my 500mW WSPR beacon was KD6RF (7547km) 1736z.

22 Feb 2015

QRT on 10m now, on 160m WSPR now and overnight

The 10m beacon has been turned off until after breakfast tomorrow, but the 160m WSPR station is still running and will remain on overnight.

Later tomorrow I will probably try a different band, most likely 40m on the Par end-fed triband antenna. It will be this antenna that my 40m Pixie will be tried on. On 40m this antenna is quite low so further WSPR tests will be useful.   As this triband antenna is also the antenna used on 10m I shall have to go QRT on 10m when I fire up on 40m.  This probably won't be until early evening Monday.

Pixie (40m) progress

40m Pixie kit
Pixie kit - being built
After carefully unpacking this kit today I checked all the parts were there and measured all values for correctness. The kit was very well packed and everything was there. Even at the price I paid ($10 with shipping by air included) it represents very good value.

The kit comes with a nice silk screened and well labelled PCB, crystal, all parts, schematic and a parts list. It would be hard to buy the bits for the price I paid. G1KQH paid even less!

I now realise that for close-up work I need better glasses!  Fortunately I have a small assembly aid that includes a magnifying glass. I am taking the build slowly and it is quite exhausting for me.  However, the actual assembly is going well. Last year, for me, this would have been impossible. I can still solder - big steps, HI.

Although the Pixie will be tested on the air, the important personal test is the building. It proves that, with some effort on my part, the world of experimental amateur radio is still there for me. You have no idea what this small step means to me.

Before too long I want to get out in the countryside and try again with my VLF and optical tests. It has been a long long long time.

Sunspots, 10m and transatlantic DX

Sunspot number today is 53 but 10m propagation remains "poor". At the moment here, conditions on 10m are better than yesterday. The 10m band is open to the USA.

UPDATE 1506z:  There are far more USA and Canadian stations copying my 500mW 10m WSPR beacon today than yesterday.

UPDATE 1946z:   The last USA station to spot me today was W8EMD (6211km) at 1840z. The first today was K9AN (6505km) at 1304z.

10m WSPR spots today - Sun Feb 22nd 2015

The first spot of my 10m 500mW WSPR beacon from a USA station today was K9AN (6505km) at 1304z. Conditions on 10m do seem better than yesterday which was pretty dire.

21 Feb 2015

160m this evening so far

At the moment the best DX on WSPR TX ths evening using my FT817 (3 blobs) into the earth-electrode "antenna" in the garden is 853km to Denmark.

So far, since trying my earth-electrode "antenna" on 160m, I have received WSPR spots (reports) from 37 unique stations and results have well exceeded all expectations. Best TX DX the night before last was northern Spain.

Testing time - 40m Pixie

Tomorrow I am going to try to build my little 40m Pixie kit that I bought for just over £7 from China. This build is an attempt to see if I am "up to the job". I know the limited performance the Pixie is capable of and on 40m BC breakthrough may be a major issue here in the UK.

I really really miss doing real building and truly experimental amateur radio. This is a step on a long road. My health has been so poor in the last 16 months or so that there was no way I could have attempted this before. People have been very kind and offered me building help and help with antenna erection. These offers have come from all over the world - the world is filled with good and very kind people. There are far more good and kind people than evil ones.

By normal standards a little Pixie build would be trivial. For me it is a major step and test of my current abilities. I do so hope I can manage this! Please don't laugh - to me it is a major step.

10m USA spots today

It has been a "bad hair day" on 10m today.

The first USA station to spot my 500mW beacon was at 1610z (very late) by WG2Z (5600km). This reminds me of the brief 6m F2 openings to the USA many years ago. To be honest, I was beginning to think that an opening to the USA would not happen at all today. In a few months we'll be on the look-out for multi-hop Es across the Atlantic in the Es season.

UPDATE 1808z:   Only 2 USA stations have spotted my 500mW beacon today with K9AN (6505km) at 1754z.  I suspect conditions are changing.

UPDATE 1940z:   It now seems that the 1902z spot by K9AN of my 500mW 10m beacon was the last today by a station in the USA.  Since then, just local UK spots.

UPDATE 2010z:   Now going QRT on 10m.  Still active on 160m WSPR where I have received 36 unique spots using my earth-electrode "antenna".

President Lincoln Mk 2 (V3)?

As the price has dropped to £199 (a drop of £50) from Nevada I am now very tempted to buy one of these as 10m is my favourite band of all.  It is just coming up to the Es season too. Power output is ideal (for me) and it does all modes. I owned the original Lincoln President transceiver and it served me well for many years.  It worked all over the place on SSB and even on 10m AM.

This is basically a CB radio with bells and whistles, although as delivered it is 10m amateur band only. It covers CB bands with a simple, illegal in UK, mod.

Anyone any views?

Sunspots and 10m - Feb 21st 2015

Sunspot number has dropped back a bit. Today the number is 53. 10m propagation is expected to be "poor".

UPDATE 1202z:   Best DX on WSPR with  my 500mW beacon this morning was just now with YV7DX (7294km) copying me at 1156z.  Several spots earlier from LZ, SV4, SV9 and 4X1. Conditions on 10m don't look "poor" to me!  I am also being spotted by local G stations.

My little W5OLF WSPR-AXE-CW 10m beacon is just brilliant! I love it. So small and perfect.

31 unique 160m reports received

Since trying my earth-electrode "antenna" on 160m, I have received WSPR spots from 31 unique stations so far in just a couple of days and nights at 2-2.5W from the FT817 rig. Results have certainly exceeded my own expectations. It says a lot about how effective WSPR is.

More historic East Anglian churches

Isleham church
Today my wife and I  visited Isleham and Fordham churches. We have updated our other blog to include these. I am always amazed that there are so many fine churches in our region.  Many date back over 1000 years, when the population of England was just a few million.

Whether viewing these as historical buildings or places of worship, it is clear they were once of very great importance in their communities as so many people would have been involved in their construction. In East Anglia alone there are well over 1000 medieval churches!

See http://eachurches.blogspot.co.uk/ .

What will solar cycle 25 look like?

We now seem to be, on average, on the downward slope to the next solar minimum. Some are predicting that the next peak will be almost a non-event with the sunspot number peak of just 7. Of course no-one really knows, but I think it is true that most experts now think cycle 25 will be very poor. Conditions on LF/MF are likely to improve but decent F2 propagation on 10m is likely to be rare, except perhaps with N-S paths over the equator.  What is certain is no-one is really sure. Summer Es could well be the dominant DX mode on the higher HF bands.

UPDATE 2048z:  I have now gone QRT (for the night) on 10m but I will be on 160m now and overnight. Back on 10m tomorrow morning after breakfast.

USA 10m WSPR spots today

K8WW (6043km) was the last to spot my 10m 500mW WSPR beacon this evening at  1904z. The earliest USA spot today was by K4RCG (5995km) at 1256z.

Although about to go QRT on 10m, I'll remain on 160m overnight again.

160m success with the earth-electrode "antenna"

Since yesterday I have been using my FT817 (2-2.5W) into my 12m spaced earth-electrode "antenna" on 160m. Matching was via my ATU feeding a small 42mm diameter 3C90 step-up transformer. In all, 22 unique people spotted me with best DX being EA1FBU (1297km) on TX.  Best reception was 2533km of a station in Russia. The earth-electrode antenna may not be the best 160m antenna but the results prove it certainly works! To be honest, the results of this test surprised me. The current meter was barely moving and ERP must have been in the milliwatt region.

Sunspots and 10m propagation - Feb 20th 2015

Sunspot number today is a healthy 86 yet 10m propagation is expected to be "poor".

UPDATE 1245z:   Despite the "poor" 10m forecast I see that my 500mW 10m WSPR beacon has been copied by in West Australia by VK6XT (14719km) several times this morning, as well as being copied in Russia and Israel. Odd how when 10m is expected to be in poor shape I often find my tiny little beacon is copied on the far side of the globe!

Multiple RX responses on 160m?

I am not aware of this on other bands but on several stations I am giving WSPR reports to the same station at the same time but at several frequencies separated by 50Hz or 100Hz from the main response. I am not aware of this being an issue on other bands or an issue on TX.

Most recently I saw the issue with ON7KB and with G4BOO earlier. The issue seems to be with my end and not a TX fault.   It is not as if signals are that strong, for example the strongest from ON7KB was -13dB S/N.  As I have not seen this before and as I am a "transient" 160m visitor I am not keen to start pulling things apart.

Anyone else seen this?  I use a SignaLink USB to interface the FT817 to the PC. Maybe I have some RF getting into the heavy duty linear PSU  I am using and this only happens on 160m?

For example, I have never seen the issue on 630m (472kHz) WSPR with the same FT817, same PC interface via the same SignaLink USB.  Tonight I am not on 472kHz as I am using the kit on 160m WSPR.

I intend to stay on 160m overnight using the earth-electrode "antenna".

160m TX results so far with earth-electrode "antenna"

It is only 1805z but the results on TX with the earth-electrode "antenna" are encouraging so far.
Unique 160m WSPR TX results with 2W from 
FT817 into 12m spaced earth-electrodes in garden.

First 160m spots on earth-electrode "antenna"

PA3MET (325km) was the first station received on 160m today.  It is still daylight (will be for hours yet) so I assume this is normal daytime propagation.   S/N varied from -17dB at best to -28dB at worse. PA3MET was running 20W, which is high for WSPR.

As it is obviously working, I'll start 160m WSPR TX with 2.5W from the FT817 very shortly.

UPDATE 1405z:  GW0OAJ (240km) has just been spotted here on 160m WSPR RX at -28dB S/N. He is using 5W.

UPDATE 1430z:  G4FKK (106km) spotted.   He is running 100mW but not sure if this is ERP.  Have now turned on the 160m TX (20%).

UPDATE 1500z:   No spots yet of my 2.5W from the FT817 on 160m WSPR so far today.

UPDATE 1604z:  Apparently  G8LCO copied me at -28dB S/N but the WSPRnet database was down, so did not receive the report.  My best DX on RX so far is DF2JP (448km).

UPDATE 1612z:    Best DX on 160m WSPR RX today is now OZ7IT (853km). It is still daylight for another 2 hours here.

UPDATE 1712z:  I see that GW0OAJ (240km) and G8LCO (58km) both spotted me at 1650z, so the earth-electrodes work on 160m WSPR TX.

UPDATE 1750z:  I see now that  ON7KO (295km) is spotting me at -23dB S/N.   And it is only now getting dark!  So far, results on 160m with the earth-electrode "antenna" are encouraging.

UPDATE 1900z:   Best DX on 160m WSPR RX so far with the earth-electrode "antenna" is RX3DHR (2533km).

Mostly quiet so far on 10m

K3ZV (5600km) was the first USA station to spot my 10m 500mW WSPR beacon this afternoon at 1258z. Since then, a few other stateside spots have been received. This morning it was 10m locals apart from UR/SWL56  and one Italian. 10m seems to be "going off the boil" a bit.

 K9AN (6505km) appears to be the last USA station to spot me on 10m WSPR at 1736z.

160m WSPR with earth-electrode"antenna"

I have managed to match my earth-electrode "antenna" on 160m but the RX noise floor is S8 on the meter, which is much higher than on 630m. For now I am just on 160m RX. Nothing yet received.

Last 24hrs on 472kHz with earth-electrodes and 5mW ERP

In total, 11 different stations have received my 5mW ERP WSPR signals from my earth-electrode "antenna" in the last 24 hours with the best report being from F1AFJ (607km) at 2202z last night at -29dB S/N. In the same period I received 12 unique stations.
472kHz - unique spots in last 24 hours
If I can match the earth-electrode "antenna" I shall be trying 160m for a change this evening and overnight. G8LCO has suggested this. If the earth-electrode "antenna" acts as a loop in the ground, I'd predict poorer results at 160m as the loop would be smaller. On the other hand, the FT817 would be better on RX (greater sensitivity) and my ERP higher (I think). Not sure of the noise floor here on 160m, but it could be poorer on 160m than 630m. Proof will be in the results - that is the fun.

Sunspots and 10m - Thurs Feb 19th

Sunspot number has climbed to 95 today and 10m propagation has changed from "poor" to "fair". So far today just locals spotting my 10m 500mW  WSPR beacon but during last evening and overnight G4CUI was copying me I think via tropo and aircraft reflection on 10m WSPR at 172km.

UPDATE 1800z:   So far today 7 unique 10m spots of my 500mW WSPR beacon from the USA.  13 unique stations altogether on 10m today.

Lincoln President (MK11 v3) down in price

Steve G1KQH has seen thst Nevada has reduced its price for the latest Lincoln President rig for 10m (and CB illegally). It was £249 but now £199, a saving of £50.

472kHz

I have been on 472kHz WSPR all day. No new stations spotting me or being spotted but some decent DX with 5mW ERP from the earth-electrode "antenna".
Unique 472kHz WSPR spots today

No USA spots today

For the first time in a long time my 10m 500mW beacon was not copied at all in the USA today. The low power may not have helped and others may have been more successful. However, it may be a sign of things to come? The danger is falling conditions will see more people give up on 10m WSPR which would be a great pity. The next few years will be very interesting on 10m, especially outside the Es season.

AM on 28MHz and up

Much to my surprise, the RSGB actually published my recent letter to their "The Last Word" column in RadCom, together with a (pathetic) reply from their Spectrum Chair. At least my letter was printed.

The response did nothing to address my concerns. Although the RSGB claims not to be anti-AM, you'd find this hard to believe with a look at the most recent band plans. AM has its place on all bands from 28MHz upwards. I just wish the RSGB and other national organisations would simply acknowledge that this mode has its place. It may be a minority interest mode, but in my experience it is the simplest mode from a building viewpoint.

Flempton, Suffolk

This Suffolk church was open.  It is situated on the A1101 between Mildenhall and Bury St Edmunds.

It is famous for a window dedicated to the last lord of the manor. The parishes of Flempton and nearby Hengrave share the same vicar these days. See http://www.suffolkchurches.co.uk/flempton.htm . The parish dates back to Anglo-Saxon times.  The churchyard was fairly wild and rambling, but delightful nonetheless.

We ate next door (just behind the church) at The Greyhound pub where we enjoyed good, simple pub grub but with excellent service. Being right behind the church, I can recommend this pub. It looks nothing special but both the food and service were excellent.

I am afraid this post has nothing to do with amateur radio! I took no gear with me.  My wife and I just enjoyed the winter sunshine and temperatures of 10 degrees C.

See our blog about visits to East Anglian Churches .

Internet of Things (IoT) already here

 This morning I received this email from KK4HSX saying that (certainly in the USA) Amazon is already selling wifi connected slow cookers called "Crock Pots". Not sure if this is a stateside generic term.
It's already here. Behold,the Crock Pot you can monitor and control with you phone.

Falling sunspots

Yet again, sunspot number has fallen , this time to 40 with "poor" 10m conditions expected. I wonder if we'll see 10m open to the USA after lunch?

UPDATE 1100z: So far just G3YAC (12km) and G4IKZ (18km) spotting my 500mW WSPR on 10m this morning with no DX from even Europe or Russia in evidence.

Landwade

Landwade was the site of my first "over the horizon" optical tests. The tests were successful, but predate my stroke by some time. I remember well being surprised at the reception when "on beam".

We go here each year about this time for a delightful walk of about 1.5km calling at the small private church (locked these days). The church is surrounded by seas of snowdrops and aconites at this time of year. Landwade is very quiet at all times. It is in Suffolk but was in Cambridgeshire until 1994. It has been occupied since Roman times, but consists of a few farms, a hall and the odd cottage these days.

I have updated one of my other blogs.
See http://eachurches.blogspot.co.uk/ .

Sunspots and 10m WSPR

Sunspot number has fallen yet again to 44 today.  We are definitely on the way down now. 10m propagation is expected to be "poor".

The 10m band did open to the USA yet again.
