Cloudlog Station Diary Hub

Nice to see swallows in the yard for the first time this year. We first saw one about a mile away a week ago.

Pleased to find V85NPV on 17m CW this afternoon with a good signal. I've heard him on a few bands recently, but not made any headway in working him! It wasn't the easiest QSO this afternoon, but Didier pulled me out ok and that's a nice new country. I haven't worked Brunei often. I remember working it years ago as G4VXE when Nigel G3TXF went there and I'm sure a QSO or two with others, but that's about it.

My QRZ page says that I don't really do QSL cards which I don't. I get the odd card which I'm happy to reply to with a local postcard or something. One arrived today from F8IJV for a QSO on 10m FM about 3 years ago! Lovely note inside saying I was his only GW, so will sort that out in due course.

Conditions must have been a little better this morning as when I called Graeme VK5GG on 20m CW he could hear me. Not well, but well enough to swap reports and say a quick hello. Tuned down the band a bit and could hear ZL1HJ again, in conversation with a French station. ZL1HJ, interestingly, seemed a little weaker than yesterday, I heard him say he was beaming over the North Pole.

I must have been catching the band just right in the morning to hear the ZLs. This morning, just before we had to head out for our Welsh lesson, I heard ZL1HJ. I did try to give him a quick call around 0825z but perhaps fortunately, because we needed to go out, he didn't hear me.

By the afternoon, conditions certainly didn't seem that great, but as ever, it was nice to work Joe AI0Y from North Dakota on 17m. Things are bad if Joe's on 17! I often work him on 10 or 15m. V47EM was coming through on 15m, but decidedly weaker than yesterday.

It started off feeling like one of those mornings when no-one can hear you. I called Graeme VK5GG on 20m CW who didn't seem to be able to hear me at all today and then a couple of distant Russians who couldn't either. The morning was 'saved' by Drew VK3XU who was just down the band on 20 CW. We had a nice chat and I reminded him of his rhombic on 40m and the QSOs we used to have fairly soon after I was licensed.

Bit of a busy day! First thing we collected some bees and got those set up into their new hive behind the barn. After that it was PW VHF column morning - so nice to get that written and off to Don. We went to Lower Town for a walk in the afternoon, so it's 1530z and I haven't made a contact yet! A few minutes before I have to go out again.

From what I can see, HF conditions are poor again, with 10m all but silent - there's the odd weak PY about. This morning there seemed to be a little Es on 6m, with a few stations from France and Switzerland coming through.

Well, you know conditions aren't great when you tune across 15m at the weekend, with a contest going on and there's only one or two stations audible!

Back on 20m, there was more going on. Curiously, stations from E7 were very loud as were UA9s - and fairly little in between!

Solar flux at 98! That feels like it's the first time it's been under 100 in a long while. Maybe I'm wrong as until recently, I hadn't noted it each day - but it hasn't happened often.

Perhaps that will augur well for the Sporadic E season this year. Last year, in Practical Wireless, I explored the 'Old Wives' Tale' as Dave G4ASR called it, that high sunspot years were poor for Es. Yet, it felt to me that it was so. I thought back to, I think 1989, when we went to Porto Santo for 50MHz and 144MHz and operated as G4VXE/CT3 and it was a really tough Es year and it was around the peak of cycle 22. Since then, I've gently noticed a correlation. Last year, I asked Jim G3YLA about it and he felt that there was perhaps a 'loose correlation' on the basis that if there is a lot of solar disturbance, then Es struggles to form. Jim suggested that any day when the K was over 3 then the Es would struggle to form.

HF conditions haven't seen great today and also the bands have been noisy with strong winds affecting the overhead power lines.

Had a nice chat with Roger GW5NF on 80m. He reminded me that there is a CE0 expedition on at the moment. I ought to try and track them down. It's not a bad path from here. I remember my first QSO with Easter Island as G4VXE on 10m CW using an ex-CB aerial back in around 1983/1984.

Paul G4RRA messaged to say that he'd worked UT1FG/MM this morning but wasn't sure about the square. So far I've only seen one decode from Yuri, presumably by aircraft, so I'm not hopeful of a QSO at this point. On the other hand, it's a misty morning here, which can do wonders for tropo - so we'll see.

Didn't get to the shack until later on as a busy morning with visitors and work here. Both Paul G4RRA and Andy GW0KZG had kindly messaged to say that Yuri UT1FG/MM was in IO22 on 2m FT8. Yuri is apparently running 20W as his amplifier is not working. I saw a few isolated decodes from him during the morning but gave him a random call when I got to the shack and somewhat unbelievably, he came back! Even better, it turned out that he was just crossing into IO23, so a few minutes later, I was able to work him from there as well.

Well it's my birthday! I was saying to Brian WB4IT last night that I've been licensed for 43 years now (I just checked and my first day on the air was 16th Feb 1983). I think I find it even more fascinating than I did then....

It's interesting being able to monitor 2m and 6m FT8 at the same time, one of the best things I did last year! For example this morning, I noticed a quick meteor burst on 2m at 0925z of F8PKC (JN38) while over on 6m, at 0924:45z the same burst produced F1PBZ (JN26) and G7TQB (JO00). Tying the two bands together make it clear that the propagation for all the decodes was meteor scatter, but individually, I don't think I would have known, particularly for G7TQB - I'd have assumed aircraft scatter (which of course, it could still be, but it seems unlikely).

Storm Dave went through last night, so I'd dropped the 80/40/15m mast down. Winds were normal this morning, so I've put it back up again. Still on the smaller vertical for HF. VHF conditions have moved away to the east now.

There's an SP contest on HF which I don't feel enthused about, so just been turning around on 17m this morning - a couple of Russian special event calls as well as EA8A.

Interestingly, I put the 6m rig on the vertical today, thinking that there might be some early Es around and having the vertical on means you can listen in all directions. Didn't hear any Es, but around 1910z I copied PY5CC and PP5ZP, probably the only stations I've heard outside the UK on 6m all day.

17m pretty quiet this evening, so popped onto 20m CW and worked Brian WB4IT in Alabama followed by Sandro I7ALE.

Checked 2m around 0625z as it had been good yesterday and sure enough CT9ACF was there, working G4KWQ. He seemed to go off pretty promptly after that QSO, so I didn't get a chance to call. Fortunately, by the time I'd showered and fed the chickens (and Duke the neighbour's horse), signals on 2m had improved and I was pleased to work Stevo. I wondered whether I might hear anything on 70cm and to my surprise, he was coming through there as well - so called him and was very pleased to work him - on the vertical of course.

Not my best DX on 70cm (EA8 is about 500km further) but a welcome new country and one I was hoping to work.

Got back from the tip at around 1030z and saw EA8CSB calling CQ on 2m FT8. Not too strong, but I have a recollection that like me he uses a vertical. Gave him a call and he responded, but unfortunately signals faded and we couldn't complete the QSO.

Got back from tip run number 2 around 1200z and could see I'd received one or two loud decodes from EA8CSB on 2m while I'd been out. Tried a CQ down that way which he heard well, but probably wasn't in the shack. Popped over to 70cm for a CQ or two (no replies) but when I went back to 2m, EA8CSB was calling me at a steady -10, so this time we were able to complete the QSO without any problems.

According to the Hepburn forecast, the propagation will move away from me this afternoon - but it was a good morning.

By the afternoon, the VHF/UHF propagation was moving off to the East. Had a little play with the automatic FT8 app on 17m, but fairly unsuccessful (conditions not software!). Bands seemed poor in the evening - did work W1AW/4 from NC on 17m, but little else doing.

Some 2m propagation down to CT3 this morning - around 1000z - CT9ACF made it to around -15 here. On the vertical of course, so he would have been a great signal on a 'proper aerial'. I wasn't in the shack at the time otherwise could have probably worked him.

You can see that here, we're on the edge of the propagation, at the moment at least. Around 1400z, GM0HBK was visible for a couple of periods on 2m.

Other than that, a fair bit of testing with the automatic FT8 QSOs on 18MHz, running 100W (under close supervision!). The software did well only requiring a little manual intervention. Will I be doing lots of this? I don't think so, but it's fun to get going as well as possible.

When you look at the solar data for the day and think....oh! I guess the transpolar paths may not be great today then.

Played a bit of HF FT8 as I was testing an interface that Pete MM9SQL is building between WSJT-X and Cloudlog. Looking useful so far. Nice to catch Rene DL2JRM operating as UT/DL2JRM which must be a new WAFOCC country.

A bit more semi-automatic FT8 operation on 17m in the evening - not sure I want to do a lot of this, but it's quite interesting to get going!

Started off looking for T31TTT on 12m FT8. No sign - but did find TT1GD which was a nice one - I thought it was a new country but after logging it, I noticed I'd worked TT8XX on 10/12m before.

Another QSO today with RI0SP up in the Arctic, this time on 17m CW. He had a very fluttery signal, perhaps not surprising where he is, up in the polar zone.

Bit of a play in the 13z CWT. Hard going to North America on 20 earlier on, but improved later and 15m too - although only really hearing the East Coast. Jim K6AR audible on 20m, but couldn't attract his attention this week.

Nice chat with Roger GW5NF on 80m SSB this afternoon. Missed the 19z CWT as went out for a bite to eat with a friend, but tried a CQ call on 17m when I got back and was really surprised to be called by Dave AL7LO in Anchorage, Alaska - a very easy and enjoyable QSO. I *think* I've only worked Alaska on satellite from here before - and then a nice chat with John W8FJ to close out the day.

DX Chrono Desktop Running on Raspberry PI 5

I have been struggling a bit with Pygame on my Raspberry Pi 5 running Wayland, but last night I finally fixed the last couple of bugs, mostly related to the day/night terminator overlay and I have to say its working really well, currently running it in my shack and also on the shack tv at Charlie GM1TGYs so we shall test for a few days just to make sure its good before we start looking at public release

Spotted S21WD on 10m FT8 as I got into the shack with 4 streams. Getting nowhere as I write this and will probably head outside and work on the strawberry bed in a moment. As it turned out, they stopped transmitting - so I dropped down on to 20m CW and had a quick chat with Willy LY2PX. Lots of fading - whereas Willy is normally a great signal on 20m in the morning.

So far, I haven't written very much about VHF/UHF activity here. I suppose that's because it's been very quiet on those bands here lately. I got into the shack after we replanted the strawberry bed this morning to find a screen full of CQs on 2m FT8 from GM0HBK up in IO77. This is not entirely unusual and happens a few times a year. It's a good path up the Irish Sea and towards the Western Isles. When conditions are good, I can work 'HBK using 50W to the vertical and we've made it on 70cm as well.

I tried a CQ when I got back to the shack and although it was well heard, it wasn't heard up in IO77! Nice to see some better propagation on 2m though.

A nice QSO on 10m around lunchtime was RI0SP who seems to be up in the Arctic somewhere! There's a picture of a polar bear on his QRZ page! I gather both CY0S and XX9W are QRT now. Pleased to catch Red DL1BUG operating as TY5FR on 12m CW this afternoon.

Ten metres brightened up what seemed to be a fairly poor day for DX in spite of a half decent solar flux; XQ6CF, PY1AX, CX5FK and HH2K in the late afternoon.

Popped out for the evening and when I got back, I was pretty amazed to see this on my 6m screen! Only one decode and I'm sure it wouldn't have been possible to make a QSO. Even so, it looks like I was the only person in the UK to receive VP8LP this evening. He had plenty of spots in Southern Europe as well as North America.

Pleased to find the noise on HF reduced this morning - it's still there, but not as bad as last night. The wind's dropped and it's not as damp, which probably helps. Bands seem pretty quiet this morning though - activity wise.

Got back from a few errands in Fishguard to find Pete MM9SQL had implemented a widget for Cloudlog to show if you are on the air and what frequency you're on. That's on my QRZ page now. Also a message from Ed at RadCom asking if I'd be interested in reviewing the new Moonraker Luna transceiver - the answer of course is yes! The rig's sold out, so it maybe a little while before I get one to have a look at. It looks similar to the TYT copy of the Yaesu FT-8800 although not identical - so I'm guessing it's from a similar but not identical stable..

Had a few calls to try and work Andy 5X2VJ on 10m CW and also S21WD on 20m FT8. Similarly no luck. Time for lunch!

I did catch Andy after lunch once the pileup had run down a bit. It was tough knowing where to call as the pileup was inaudible here. Spent a little time over lunch looking at the pictures from Nigel G3TXF and Ian G3WVG from their operation as 3B8XF and 3B8VV respectively. Looks nice!

Finished some work in the house and came up to the shack with a cuppa and was pleased to find new FOC member, Randy, K5ZD operating from V4 - I managed to sneak a QSO in just before he went QRT. I enjoy working SOTA and POTA portables and working portables from North America is a real thrill. Mike WB2FUV is a regular operator and I've worked him a good few times now. Had a QSO with Mike on 18MHz this afternoon - signals were really marginal today - but we managed to swap reports ok.

CY0S and S21WD expeditions busy on 20m CW after 2030z. Managed to work S21WD which I thought was a new country but apparently isn't! Also nice to catch VK2GR, not as loud as sometimes, but an easy QSO. CY0S had an operator change and Sean G3ESE had posted his QSX frequency on the cluster - tried there and they came back first call. Nice to get CY0 on 20m CW as well as FT8.

Been a fairly productive few days on the Cloudlog dev branch, mostly focused on performance, usability, and a few long-overdue features.

On Air Widgets (Finally)One of the nicer additions this week is a proper embeddable “on air” status.

There are now two options:

/widgets/on_air/YOURCALL → iframe-style widget/widgets/on_air_image/YOURCALL → SVG badgeThe SVG version is probably the most useful. It’s lightweight, updates automatically, and can be dropped into QRZ pages, blogs, or wherever.

It shows:

ON AIR / QRTFrequency + mode (or SAT if applicable)Also spent a bit of time making sure it behaves nicely:

Sensible caching (not too aggressive)Dynamic sizing so it doesn’t look awful with longer textProper sanitisation so nothing explodes in SVG landDX Highlighting – Much Smarter NowThis has been bugging me for a while.

Previously, Cloudlog would only highlight DX properly if the distance was already stored, which meant perfectly valid QSOs could get ignored.

That’s now fixed.

We now:

Fall back to gridsquares (and VUCC grids)Calculate the distance if it’s missingPick the actual furthest QSO rather than “first one that matches”Result: more accurate DX highlighting without relying on perfect data.

DX Cluster ImprovementsQuite a bit of work went into the cluster side, too.

UI & BehaviourStatus is now a proper badge (instead of boring text)Handles connection states better (connecting, reconnecting, etc.)Tooltips now actually make senseFilteringAdded mode filterAdded “New DXCC” filterImproved how spots are held until worked status is knownRBN FixesTightened up RBN detection so it stops misclassifying random spots as skimmers.

(That regex was… optimistic.)

Track BandNew option to track the radio band automatically, or turn it off if you prefer manual control.

DX Cluster in the QSO ScreenThis is probably the biggest user-facing change.

You can now enable a DX Cluster tab directly inside the QSO interface.

Live WebSocket feedClick a spot → fills the QSO formOptional auto-QSY to your radioIt basically removes the need to bounce between pages.

QSO Form – Faster & Less ChattyMoved a bunch of calculations client-side:

DistanceBearingLocator handlingThis removes a load of AJAX calls and makes the form feel much more responsive.

Same logic as before, just running in the browser now.

FT8 / FT4 + Band LogicUpdated frequency lists and tightened up band/mode detection.

Should now be a lot more accurate when Cloudlog tries to guess:

Mode from frequencyCorrect band segmentsParticularly noticeable on VHF/UHF and some of the edge cases.

General UI / QoLA mix of smaller improvements:

Pagination no longer resets every time the table redraws (finally…)Per-user control over QSO fields & tabsCleaner contest UI with statsBetter handling of manual mode inputFewer JS errors when things aren’t initialised properlyUnder the HoodBit of housekeeping too:

Centralised DXCC checks (less duplication)Removed some questionable direct $_GET usageReduced unnecessary redraws and DOM workGeneral performance tweaks across the boardFinal ThoughtsThis release isn’t about one big flashy feature — it’s more about:

Making things fasterMaking things more accurateAnd removing a bunch of small annoyancesThe dev branch is looking pretty solid now, so aiming to get this rolled into a stable release soon™.

More tweaks incoming as always.

Clocks went forward this morning and an early start owing to have to medicate Cedric the cockerel at 0815 meant I was in the shack early. Found FO/F6BCW on 20m CW but didn't seem to get anywhere with the pileup. T31TTT was on 20m FT8 coming through with about 6 streams. They came back about 2nd call which was very pleasing for a new country.

Bands didn't seem that exciting during the day. By the evening, there was a lot of noise on the bands (damp and the overhead power lines no doubt) but CY0S were strong enough to be heard on 17m and had a minimal pileup, so it was nice to work them on CW for a new band country.

Spent a little time playing with a nice radio control package called Wfview which talks to the TS-590SG. I'd hoped that it might work as a remote control package, but it seems their client/server setup only works for Icom radios at the moment. Looks promising for the future though.

BW QSO Party today - and Julie's birthday! So, I didn't plan too much activity as we were heading to Tenby.

Made a few QSOs in the morning and then a few on our return in the evening. particularly on 20m; VK7BO, VK2GR, TY5FR and Andy 5Z4VJ operating as 5X2VJ.

Last weekend saw the annual BARTG RTTY Contest. Like last year, I took part with Charlie GM1TGY operating as GM5G in the M/S High Power category, one radio. In the same category last year, we came #3, so I had some hope that we might have been able to improve on that, but it wasn't to be.

2 am Saturday, and on the shack's TV running DXChrono, I could see that the aurora was pretty much sitting on top of us. The result was that 80/40m was really slow going. I think most of the night we were on 80m.

Plot of all the QSOs

We knew Saturday morning we would have to go QRT as we had just replaced the SPID RAK rotator that turns the EAntenna 59+. It was, for some reason, binding, so tower over. Found the issue: a jubilee clamp was getting caught, stopping full rotation (doh). So we made some modifications and got back on the air around 16:00z. I was optimistic that 15/10m would be open, but the aurora hadn't really shifted. Hence, I ended up sitting on 20m running with a very good rate, but as night drew in and the aurora conditions dived again.

In the end we had run out of people to work around 01:00z so decided to call it and get some sleep rather than work nothing however we was back on air before sunrise around 06:00z the rate however was slow and it was just a matter of jumping between 20/40m looking for QSOs when the rates dropped 15m opened up briefly on Sunday and on 10m I worked just 3V8LL.

As Sunday afternoon progressed, conditions worsened, with more auroral flutter and distorted signals, followed by periods of the bands just going totally dead with no signals to be seen. It stayed in this pattern up until the very end.

That said, the shack was working perfectly, using a Kenwood TS890S (FSK keying), Gemini 1200 amp and our usual selection of antennas

EAntenna 59+ (20-10m)2el Phase for 40m40m Dipole80m Quarter-wave Vertical80m DipoleK9AY for RXWe finished the contest early at midnight after running out of callers, spent over 40 minutes on 80m calling CQ to myself, but we ended up with 534 QSOs, not including Dupes.

Contest Summary

Maybe next year will be better

Solar flux heading up today although conditions still don't seem that great, although we're probably starting to see seasonal decline kick in! Last year I pretty much abandoned HF except for SOTA chasing between April and September. Hoping it'll be a bit more interesting this year..

15m brightened up around 1330z, with contacts to FG/F5HRY, PJ7AA and AI0Y. Even caught 10m open to W5ZR in Louisiana around 1600z although the band was fading by then. Worked XQ6CF on 10m CW around sunset. Saw a DX spot that T31TTT were on 10m FT8. I could see their US pileup, but sadly, not them....

EX0T was a nice one on 10MHz around 1900z. Bob's DU7ET as well - always in interesting places.

Wind had dropped so I put the DX Commander Signature 9 back up.

Picked up CY0S on 10MHz CW and shortly after on 14MHz FT8 (new band country). More locally, nice to work Declan EI6FR/P out on the hills in Ireland,

I've heard XX9W on CW a bit this morning but not strong enough to have a go at. Unfortunately TX5EU went QRT while I was away, so I won't be working them :-)

Got home from Haverfordwest and Justin messaged to remind me about the 80m SSB contest. Worked him and about 4 others.

CY0S coming through well on 40m CW, but a few calls didn't work, so I gave up as I'd worked the slot already!
