Back to Par 3 band external antenna

Now the threat of storms has gone for the day I am going back on the external Par 10/20/40m end-fed wire antenna. This happened at 1515z.

Sunspot count today is zero (very low) with 20-30MHz propagation forecast to be just "fair". I shall be lucky to see F2 DX today on 10m. Es has been very good on the indoor loop.

UPDATE 1520z:   First 10m WSPR spot back on the external Par antenna was from SM6WZI (1007km)  at -1dB S/N for my 2W. This is a very good report. Again, the Es seems to be favouring more northern latitudes.

10m WSPR spots since going back to the Par wire antenna outdoors

UPDATE 1727z:  Still just the mix of EU Es stations since going back to the Par antenna.

UPDATE 1830z:  Just G8JNJ/A (184km) being spotted currently. All Es seems to have disappeared.

UPDATE 1940z:  Out of the blue pops OK2SAM (1283km) just detectable on 10m WSPR at -32dB S/N. So there is still ES about on 10m.

UPDATE 2140z:   Plenty of 10m Es this evening including spots from 3VSWL in Tunisia and DK0SC . I spotted I and EA.  As thunder storms may build overnight I shall be going QRT and disconnecting rig and antennas.

10m WSPR with Wander Wand Compact Loop

Averaging all the signals over the day so far on the Wander Wand Compact Loop indoors on 10m and comparing with the external end-fed Par 10/20/40m wire antenna, I believe the loop is perhaps just 2 S-points down or less. With Es and widely varying signal levels, it is quite hard to do the comparison. Also, the loop was not rotated, and it is possible the difference is slightly less.

On lower frequencies I think the difference will be slightly greater. Overall, I am impressed  with the indoor loop. Seeing how it is not positionally optimised (it just sits above the rigs and runs just over 2W), it does pretty well.

For future 10m WSPR use I think a 6mm or 10mm copper pipe (fixed tuned) loop will make a good external antenna. I suspect a thicker loop will be only be very little down on a 1/2 wave vertical or dipole at a similar height. The disadvantage of a loop, especially an efficient one, is the narrow bandwidth. This of course, helps on receive as the antenna rejects out of band interferers. Bandwidth should just about cover JT65/JT9-1, PSK and WSPR allocations 28.076-28.126kHz.

WSPR distances

LB9YE and I have exchanged WSPR spots several times today. When he spots me the distance is 1489km. When I spot him it is 1533km. I assume it is to do with where in the QTH square the measurement is taken from.

Storms to miss us?

According to the lightning map, it looks like the nasty thundery weather is tracking up west of us (Peterborough and Stamford area?)  and could miss us altogether. We'll see.  See http://www.lightningmaps.org/realtime?lang=en . For now, I shall keep on the Wonder Wand Compact indoor loop to see how it performs.

UPDATE 1127z:  Storms are dying out now. I think we'll miss them.

Wonderwand loop on HF

http://www.wonder-wand.co.uk/WonderWand/WW_Photos_files/TCL-ad01.jpg

Rather than go QRT because of the approaching storms, I decided to try my Wonder Wand Tunable Compact Loop antenna indoors on 20m WSPR. The loop is about 0.5m diameter. In my case, more for convenience, it goes to the rig via my Z817 ATU. SWR is perfect 1:1 on the tuned frequency. No TX spots seen yet at 2W, but no shortage of RX spots across Europe so far. The loop is just above the rigs in a far from ideal, indoors location.

WSPR spots so far today on 20m with the indoor Wonder Wand Compact Loop

UPDATE 0916z: My first TX spot on the indoor Wander Wand Compact Loop came from DJ6LB at -28dB S/N.

UPDATE 0944z:  Second TX spot was by DJ7KA at -26dB S/N.

UPDATE 1010z: I QSYed to 15m and am getting lots of spots on TX at just 2W.  Best DX report on 15m is from SM6WZI (1007km) at -6dB/-9dB S/N (i.e. strong) - it is amazing this tiny indoor antenna works so nicely. So far 6 TX spots of my 2W in just 8 minutes on 15m. Incredible. Sorry about the poor photo of the loop, but you get an idea of the set-up. It will work even better on 10m and 6m as the loop is larger electrically. Set-up is totally un-optimised: the loop just happens to be where it is.

UPDATE 1230z:  Now QSYed to 10m and the best DX on the Wonder Wand Compact Loop indoors is now LB9YE (1489km) at -25dB S/N with 2W.

 

10m WSPR spots with 2W today with indoor loop

Storms ever nearer

Currently, there are violent storms over North London and East Midlands, and they are moving towards us in East Anglia. Not sure of the pace yet, but looks like we could have storms within hours. For now, I shall keep antennas disconnected and the PSU disconnected from the mains, just in case. 10m and 6m can wait. Or I  may use an indoor wire loop instead?

See http://www.lightningmaps.org/realtime?lang=en  .

Approaching storms

Although the nearest electrical storms are some way off (West Country and over the Cherbourg Pennisula) they are likely to be here tomorrow. As a precaution, I shall disconnect all rigs and antennas before bedtime. Probably they won't be here until later in the day, but better to be safe than sorry.

See http://www.lightningmaps.org/realtime?lang=en .

SPAM comments WILL be deleted!

In the last 24 hours on both my blogs I have had SPAM comments from someone in India extolling the virtues of yoga and meditation. Nothing wrong in the right context, but the comments are totally out of context and therefore SPAM.  Both have been deleted as soon as noticed.

A word of warning to potential SPAMMERS: similar irrelevant and totally off topic comments will always be treated as SPAM and deleted.  Go away or expect such comments to be immediately deleted.

10m - evening Es

Quite out of the blue IK1WVQ (1084km) was spotted just now at -12dB S/N. Es just happens - sporadically. Also copied was G8JNJ/A (184km) by GDX. There have been watery, Doppler affected, signals visible for hours, without decodes.

HAARP - stay of execution?

It looks like the HAARP (supposedly auroral research) facility in Alaska may remain until May 2015 although non critical (movable) kit is already being moved out. It remains to be seen what happens after next year. HAARP is also known for its generation of ELF radio signals as a result of ionospheric heating. The peak power of the facility on HF was massive.

10m - tropo?

In the last few hours, I have spotted PB0AIC several times with low(ish) Doppler at 288km.  This is far too short for Es (unless the skip is extremely short, suggesting a 2m Es opening?) so I wonder if this is pure tropo? The distance exceeds most GDX  (usually possible with aircraft reflections) out to around 200km.  I have spotted PA stations before on 10m now.

Recent WSPR spots today

10m Es and GDX already

Since resyncing the clock and restarting the software around 0830z, G3JKV (123km) has been spotted several times as GDX and LA3JJ (993km) and I have exchanged WSPR spots once via Es. Strange how later in the Es season, it seems to favour more northerly latitudes.

Sunspot count today is just 11 (low) and 20-30MHz propagation described as "fair". We'll be lucky to catch any real DX by F2 today I think. This is the lowest sunspot count in a long time. Although there will still be good days, I think we are "on the slide" now and have passed the peak of this cycle.

As Es conditions worsen, I seem to be spending more time on 10m now than 6m. With patience, both bands will still be good for Es for some time yet.  Last summer I was still regularly working Es DX on 6m right into September.

I was in hospital from mid-Sept to January, so have no idea of 6m conditions during that period. In my current (wobbly) state of health, digital modes (no talking) are easier on my voice than SSB or FM.

UPDATE 0930z:  TF3HZ (1837km) in Iceland spotted at  -26dB S/N via Es.

10m - real F2 DX at teatime (and later)

LU8EX (11208km) running 5W was spotted at 1726z this evening on WSPR at -25dB S/N. This is clearly N-S F2 propagation, much to my surprise today. Even though the sunspot count was just 25, it goes to show there can still be very decent DX around. going N - S. I assume my lower power was buried in the local noise at his end. And/or there was no propagation when I was TXing.

10m unique WSPR spots today, so far - duplicates not shown

LU8EX is just NW of Buenos Aires, Argentina.  It is still possible other S.Americans will be seen before the day is over.

UPDATE 1925z:  LU8EX has now been spotted 5 times at up to -13dB S/N (strong),  No other S.Americans seen so far this evening. At this strength I am surprised not to have been heard in Argentina.  Maybe LU8EX has no WSPR RX capability or a very high noise floor?

UPDATE 2025z:  No further F2 sen here after 1902z (LU8EX).

10m - Es

At 0930z, 10m opened to Scandinavia with SM6WZI (1007km) copied. Later,, SI9AM (1503km) was copied 4 times. I will see if it opens again later.

UPDATE 1712z:  By teatime, the  10m band was pretty productive WRT WSPR via Es. Best Es DX spot was Z35BY (1956km) in Skopje. Also spots seen to/from Italy and some GDX.

10m - early GDX G8VDQ

This morning, I turned on 10m WSPR early at around 0615z. All was quiet until G8VDQ (93km) was successfully decoded a couple of times in the last hour. He is in IO91um square. There were a few weak and badly Dopplered signals (multiple aircraft reflections) copyable, but these were not decoded. Of course, some of the shift is my rig warming, but multiple aircraft reflections are clear to spot. He is using 5W (antenna not known) whereas my ERP is just 1W meaning I am probably below his noise floor. I use the FT817 (2.5W setting) via a length of lossy RG58 to a V2000 vertical.

Although early still, no Es seen yet today on 10m.

Sunspot count is low at just 25 but 20-30MHz propagation is forecast to be "normal". We'll be lucky to see N-S F2 propagation today I think, but 10m is a fickle band and you never quite know.

10m WSPR spots at last

G8JNJ/A (184km) has been spotted 3 times now. I had a partial decode hours ago (just the QTH locator IO90hx). Spotted between 2114z  and 2118z. No Es seen since turning the rig on. Today has been a very quiet day on 10m here.

FT817 - wrong setting!

Just realised that I had my FT817ND set to USB and not DIG, so I was not sending any modulation on WSPR TX! This has now been corrected, so I am hopeful of some spots this evening. This is the second time I have made this mistake. It remains to be seen if this was the reason for no spots earlier.

UPDATE 1820z:  Still no 10m spots!  Must be conditions. Will leave the rig on 10m this evening to see if things improve.

A quiet radio day

With physio this morning and gardening (as best I am currently able), the radio has only just been switched on to 10m. A few weak and watery signals are visible on the WSPR software with several Doppler shifted traces - obviously GDX - but none of it has yet decoded.

Sunspot count is 109 and 20-30MHz forecast is "normal" meaning some F2 DX may be possible. I see CX2ABP is being spotted over 8000km away in the USA.

No 10m Es seen here yet since I switched on about 1 hour ago. 

UPDATE 1745z:  Still no 10m WSPR decodes of anyone  - no locals no GDX, no Es and no F2. I was even wondering if the software had crashed, but it and the clock are spot-on. It's just a very quiet day on 10n here, so far.

14MHz to Australia - Adelaide

This evening, I went on 14MHz WSPR with a couple of watts and was rewarded with a spot by VK5AK (16224km) just outside Adelaide, Australia.  Apart from this spot and K9AN (6505km) the other spots, so far, have been from Europeans and of Europeans. I shall stick on 14MHz for a while longer.

14MHz WSPR this teatime (2W)

Semi sked 7MHz

This evening, I shall try again to work a local who is on the Isle of Arran in Scotland. Currently he is working in Glasgow but camping on Arran.

I have an S8 noise floor on 7MHz and am limited to 5W pep maximum. Although WSPR  On 7MHz at 2W WSPR is pretty easy, it is much harder work on SSB.

10m WSPR this morning - good Es

Whilst cutting the rear lawn today, I have been on 10m WSPR. There is still plenty of Es around on 10m.

10m WSPR this morning

Cutting the grass is still challenging: I still get very giddy when on my feet, but stamina is slowly improving. It may be a while before doing the lawns becomes "easy" again.  Still, the fact I can do it at all is something that might not have been possible: the worst outcomes of my brain bleed would have been horrendous, possibly leaving me paralysed, deaf or blind. Overall. I was lucky.

Rear lawn

Sunspot count today is 102 (good) but with blackouts and 20-30MHz forecast is "good", so surprised not to have seen any F2 propagation (yet) on 10m. Es so far is all from N.Europe including Scandinavia.  Nothing yet seen here from S.Europe.

UPDATE 1600z:  The Es opening today seems to have favoured N.Europe and Scandinavia with no S.Europeans seen here all day.. The 20-30MHz propagation forecast is now only "fair". As yet, no F2 openings seen here today on 10m. In past years I have noticed more Es to Scandinavia and N. Europe in the later part of the season. There must be some good reason for this, but I don't know why this is.

Ultimate 3 kit - offers of help

Our community in Amateur Radio is truly wonderful.

Already, I have had three kind and generous offers to build and test my Ultimate-3 beacon kit, which is currently beyond my building skills because of my brain injury. I still hope to build this myself, but may wait a few more months until I'm less wobbly and clumsy.

This is not the first time I have been touched by the genuine kindness of others. It restores one's faith in humankind: there are some truly kind people around. Thank you all.

Sometimes we hear about all the bad things in this world. Believe me, the world has very many kind and caring people in it.

40m WSPR

Having (unsuccessfully) tried to work a station on the Isle of Arran (Scotland) on 40m SSB, I went on to WSPR and was rewarded with the following in a single 2 minute transmission at 2W to my low (for 40m) end-fed Par antenna.

WSPR really is a great mode. I remember back earlier in the year on 40m when my second spot (on this antenna) was by a VK.

CN8LI - 6m WSPR

So far (it is now 1425z)  CN8LI (2113km) and I have exchanged WSPR spots all morning since I first went on 6m. We have exchanged spots 14 times already. Es conditions between us are perfect. My TX is on about 16% of the time only.

Unless the storms get a lot closer - currently most are north of Norwich  - I shall stick with 6m all day. I can hear thunder, but it is very distant and moving further away currently.

UPDATE 1530z: The "pipe" to CN8LI has been disconnected since lunchtime. I wonder if it will come back at teatime? Es often has a second peak at teatime.

http://www.lightningmaps.org/realtime?lang=en

No storms?

According to the lightning map, the nearest storm is over Boston in Lincolnshire some 90 miles away. There are no very recent strikes. I'll keep an eye on which way it is moving, but things here look benign, for now.

Will leave the gear on 6m for the time being unless things change. That storm map is a very useful guide to what is brewing up and heading this way.

UPDATE 1255z: Can hear distant thunder, although nearest storm is now Attleborough, Norfolk some 60 miles east of this location.

10m, then 6m WSPR

After a brief outing on 10m WSPR, I've returned to 6m WSPR since 0900z. 10m was in good shape with lots of Es about from right across Europe.

Unique 10m WSPR spots early today (repeats not shown)

6m is good too with CN8LI (2113km) already in the logs early this morning along with local G4IKZ (18km).

UPDATE 0938z: CN8LI spotted for 3rd time already.  He is getting stronger  at+7dB S/N just like a local! He is also spotting me.

6m spots to 0942z today

UPDATE 1150z:  CN8LI and I have exchanged WSPR spots twelve times already. Amazing.

Closed down station - thunder storms close

As there is thunder/lightning around, I have decided to disconnect antennas and switch off the rigs. The storms are getting closer according to http://www.lightningmaps.org/realtime?lang=en .  As much as I'd like to continue to monitor on 6m, I think to go QRT is the right decision tonight. There will be plenty of other times to monitor 6m and 10m.

UPDATE 2110z:  The worst of the storms missed us.  However, there is a lot of storm activity around still, so the rigs and antennas will remain off tonight.   Meanwhile I am watching Brazil getting beaten by Holland. Current score Brazil 0  Holland 2. Unless Brazil create some magic, they are doomed.

UPDATE 2207z: Would not like to be in the Brazilian national football team this evening.

6m - first Es WSPR today

At 1204z, the first 6m Es today was spotted here with  HB9TJM (764km) being spotted at -15dB S/N on WSPR.  A little later and he was spotting my 1W ERP at around -17dB S/N on WSPR.  No doubt there will be other 6m Es openings later. 6m Es is less common than Es on 10m. In turn 2m Es is far less common than 6m Es: the higher you go, the less frequent it gets. 10m is the easiest Es band (in my opinion) and you get F2 openings more frequently, especially N-S, than on 6m,where F2 openings are rare.

HB9TJM claims to be running 10W, which, if correct, is quite high power for 6m WSPR.  A more common power is 5W or less.

UPDATE 1427z:   CN8LI (2113km) has been spotted twice so far (by 1745z this was 4 times) on 6m this afternoon at 1340z and 1348z. On both occasions he was very strong indeed on WSPR.

The first 3 spots of CN8LI today on 6m WSPR

UPDATE 1440z:  G4IKZ (18km) must have his horizontal Moxon in just the right position as he has been giving me excellent reports all day. No further Es seen here since CN8LI earlier.

Ultimate 3 beacon - still unable to build it

I am still far too clumsy to build this kit. This morning I was going to start on the LPF but I am still far too wobbly and clumsy to do it. Before my brain bleed this would have been a piece of cake, but today it is too much for me. Damn. I shall wait another month to see if I feel better. Blogging and WSPR I can manage. Talking in contests is hard work, but I can just about manage it for short periods.

Maybe I have to conclude it is too much for me and call on the help to build and test the unit so kindly offered? I did check the full pack and the GPS module is definitely not there but a surplus relay board is. I shall have to contact Hans Summers and return the unwanted PCB and request the GPS module that I paid for but that has not been delivered. It is some months since the bits came. I resisted opening the package until I thought I could build it. I photographed the opening and was very careful.

On reflection, I wonder how much they would have charged to build and test the unit for me?

I hate being unable to do this sort of thing: it feels like I am past it. Please no.

6m WSPR this morning

Since 1026z, I QSYed back to 6m WSPR. So far here, just locals and GDX, no Es seen so far.

6m WSPR this morning - no Es so far today.

10m - early morning GDX and Es

The 10m WSPR kit ran overnight. WSPR spots of G6NHU (78km), G7EOB (76km)  and G8JNJ/A (184km) and Es early this morning from IK1WVQ (1084km) , EA6GF (1428km) , EA5CYA (1376km) .  Spanish Es was being received at 0722z - very early.

Will be QSYing up to 6m shortly.

UPDATE 0950z:  10m WSPR is mainly from stations in southern Europe by Es now.

10m - evening Es and F2

10m was open this evening for Es around Spain and N. Africa with WSPR spots exchanged with several stations in Spain and SWL reports from 3VSWL (1845km) in Tunisia.

Also audible at 2044z and 2130z was CX2ABP (11127km) in Montevideo - very late. These are the 9th and 10th spots of this station today. I just wonder if we are seeing an Es opening to Spain linking up with an F2 opening nearer to the equator? Or is this just pure F2?

UPDATE 2156z:  EA5CYA still being spotted here strongly at -10dB S/N on 10m WSPR.

UPDATE 2212z: Being spotted strongly by EA2CNU as late as 2204z. Just off to bed now.  I shall leave the 10m WSPR kit running overnight.

EA5CYA - teatime Es on 10m WSPR

Since 1626z EA5CYA has been coming in via Es at a reasonable level for his 200mW.  I suspect there will be further Es spots this evening. It has been rather quiet on 10m Es today so far.

CX2ABP - 7 times so far this afternoon

CX2ABP (11127km) has been spotted here seven times since lunch so far. Rodolpho is using 2W but is a very consistent signal with me. He has one of the best signals from South America. Not sure what antenna he uses?

UPDATE 1645z: CX2ABP has now been spotted 9 times this afternoon. Conditions N-S on 10m are good today.

10m F2 propagation this morning. GDX this afternoon

FR1GZ (9724km) was spotted several times on 10m WSPR around 0930-1000z this morning.

Sunspot count is 159 (good) and 20-30MHz propagation "good",which is probably why FR1GZ was putting in an appearance today.   

EA5CYA was spotted (by Es) at 1118z and LB9YE at 1156z.

Also spotted were local G4KPX and more distant G6NHU (78km).

In terms of GDX, 10m seems better than 6m. Es is also better on 10m and there is still F2 around on 10m, which is all but absent, from here at least, on 6m. If I had to choose between the two bands, 10m would be my favourite. At the moment I am enjoying both bands.

UPDATE  1445z:  Best DX spot is of CX2ABP (11127km) by F2. Best GDX spot is of G8JNJ/A (184km). The best spot of my 2W ERP is from G3JKV (123km). Lots of spots exchanged with local Richard G4KPX (14km). who lives in Ely.

10m GDX and Es

My PC was doing odd things again earlier - said WSPR was TXing when it was not - but restarted WSPR software and all OK now.

G8JNJ/A (184km) GDX and EA5CYA (1376km) via Es (twice)  seen here in last hour.  The long F2 DX to South America seems to have gone now?  I love 10m -  a band of true variety and not hard in any way. My antenna is a 3 band Par end-fed 10/20/40m just strung to a nearby tree and not that high. On 10m I am currently using 2.5W from the FT817. The cable loss take this down to about 2W (max) at the antenna. This seems to get out fine. I am sure with a more efficient antenna just a few mW would be enough, although 5mW to this antenna has got spots from Israel and 100mW from the USA. Maybe it is somewhat directional?

At the moment my TX is only active 6% of the time on 10m. I am mostly on RX.

UPDATE 2030z:  Nothing further heard from CX2ABP in Montevideo since late afternoon.  He is using 10W, so if the 10m band is open, I would expect to copy him.  G8JNJ/A (184km GDX) has now been copied several times already this evening at up to -22dB S/N. Not strong, but there.

UPDATE 2112z:  G6NHU (78km 100mW) has been copied at -24dB S/N from JO01ou. Just a local and GDX currently.

UPDATE 2128z: Just when you think that is it for the evening up pops EA5CYA at 2118z at -21dB S/N and again at 2126z. So there is still Es around. even this late. I shall reset the software and clock and leave the kit running on 10m overnight.

UPDATE 2204z: G6NHU and EA5CYA are still being spotted.

10m WSPR

As 6m was looking pretty quiet, I decided to QSY down to 10m at around 1500z. Within a few minutes CX2ABP (11127km) was being spotted (F2 propagation) at -22dB S/N. 10m is in decent shape. So far, CX2ABP has been spotted 5 times in the last hour. Best report is -15dB S/N with his 10W.  He has yet to spot me, as has anyone else on 10m.

6m this morning

A quiet morning so far on 6m with a little GDX but no Es seen yet. M0EMM (192km) has exchanged spots with me around 1118z. Also local G4IKZ (18km). Otherwise quiet.

Conditions 20-30MHz are described as "good" with sunspots 183 with blackouts. Maybe I'll QSY to 10m later unless 6m improves?

6m - Es today

The 2 spots of me by 9H5G (2116km) on 6m WSPR mid-afternoon appear to be the only Es seen on 6m here today. There may have been Es earlier but I was out and did not have the rigs turned on. Since 1544z, I have been copied by local G4IKZ (18km) only.  My best reception was of G4NRG (58km).

Do I stick with 6m WSPR tonight?
