10m WSPR - 2W ERP
After recent total disappointments on 6m - total blanks after 5 days attempts - I have returned to 10m WSPR at 2W ERP from my Par antenna. So far, results both given and received, are encouraging.
Sunspots and 10m
Sunspot number today is 96 and 10m daytime propagation is forecast to be "fair".
I am already copying RA3APW's 100mW WSPR beacon from Moscow, HS0ZKM (9485km) is also coming through via F2 on 10m WSPR. There are lots of Europeans coming through on 10m WSPR.

QSY down to 472kHz
At 2020z I QSYed back down to 472kHz WSPR and was immediately exchanging spots despite running just 5mW ERP from a very indifferent antenna and ground system.
472kHz is a most interesting band and I urge more people to give it a try, even if just on receive initially. Here, the FT817 is used directly on RX and certainly hears stations right across Europe. I am able to hear from LA to I to EA and right across the continent between.
UPDATE 2045z: M0PPP is putting in a massive -2dB S/N 472kHz WSPR signal currently. G8VDQ (93km) is a new station in the last 2 weeks copied here this evening.

Trying 6m WSPR again today
Well, I must be a masochist! I am yet again trying 6m WSPR in the hope of some GDX, Europeans or even some TEP. As yet, nothing at all - dead. I am using 30dBm ERP from my vertical V2000 VHF/UHF antenna.
UPDATE 1130z: So far on 6m it has been totally dead with not the slightest hint of signals - no MS pings, no aircraft Doppler from possible GDX - absolutely nothing seen at a.ll. It looks as if today will be as bad as the other recent days when I tried 6m WSPR. A pity, but I'll keep trying.
UPDATE 1404z: Still absolutely nothing at all on 6m WSPR. I'll keep going for this afternoon, but I really am getting nowhere on the band. It suggests the Europeans on 10m are probably F layer backscatter otherwise I might have expected some Europeans on 6m Es too.There are no stations at all copyable on 6m.
UPDATE 1635z: 6m still absolutely DEAD here still. Will continue to try until after tea time.
UPDATE 1715z: I have (reluctantly) concluded, again, that out of season 6m WSPR is a total waste of time. Today is the 5th day in recent weeks I have tried and not a single station has been seen on the screen (even those not decoding ) or spotted me. I think it is time to call it a day on 6m WSPR. Tomorrow iI shal try on a different band.
UPDATE 1930z: That's it then. After 5 DAYS of trying on 6m WSPR I am now going QRT as I have been spotted by no-one and no-one has spotted me. It was a dead loss and total wasted effort. QSYing shortly to MF.

Sunspots today
The sunspot number today is 107 and 10m daytime conditions are forecast to be "fair". If recent days are typical, this means 10m should be good for some F2 propagation, including North America after lunch.

Last spots of my 10m WSPR at 50mW in the USA
KU4QI (6406km) was the last to spot me today at 1648z. Since then, just local G4IKZ (18km) has been spotting me.
I think it is time to QSY to MF (472kHz) WSPR for the night.
UPDATE 2036z: have now QSYed to 472kHz WSPR. DK7FC (669km) is, as always, putting in a very decent signal here. Just G0LRD (25km) spotting my 5mW ERP so far.
UPDATE 2200z: 8 unique stations seen so far on 472kHz WSPR this evening so far. Several have been spotted many times.

W5OLF WSPR kit
Jay has been working on new versions of his little WSPR beacons. All being well I should receive a 10m 500mW out version in the next few weeks.
Jay is writing the manual(s) and has asked me for my feedback, which I shall, of course, provide. The new version is a single board (again) but transmits continuously, randomising the TX frequency on each TX burst to minimise interference to/from others. It needs several minutes to thermally stabilise but uses the uP to generate everything needed such as the WSPR tones, so no PC is needed. The transmission is started manually on the start of an even minute with a push button. The PA can be separately enabled.
This should be fun. I'll give more information when it arrives and I get a chance to try it on the air.

Plenty of stateside 10m WSPR spots at 50mW
I think the 10m band has now closed here for the day to the USA with 50mW on WSPR. In the end, there were plenty of USA spots at this power level. As I said yesterday, 500mW will seem like high power! 28 spots (if I counted right) since 1150z and I was only on 20% or less TX.
Tomorrow, I may try a different band completely for a change.

Inspecting antennas - by radio controlled quadcopter!
Some years ago I went to a BBQ where someone had a wi-fi controlled quadcopter remotely controlled from an iPad. It was very impressive with its on-board cameras for navigation and filming what was happening down below.
I see AE5X has a video showing the inspection of his antennas (from above) using one of these. My antenna farm is trivial by comparison and can be pretty well examined at ground level.

First 10m WSPR 50mW stateside reports today
At 1312z, W3CSW (5886km) and WG2Z (5600km) were the first USA stations to spot my 50mW WSPR signal today, at -26dB S/N and -21dB S/N respectively. Others are now following. KB9AMG (6300km) has spotted me twice now. At the moment there seem to be fewer USA spots with my 50mW on 10m WSPR than yesterday? Early in the day I guess. Things may change.
UPDATE 1536z: W3CSW is now copying my 50mW 10m WSPR at -19dB S/N, implying he would probably copy me on 5mW or even less if his noise floor is low.

10m WSPR 50mW
VK5MR (16144km) was still being copied on 10m WSPR this morning despite the 10dB pad in my antenna lead.
So far, the first USA station copied here was W3CSW (5886km) at 1220z.
Best DX spots of my 50mW on 10m WSPR this morning came from LZ1OI (2153km), CT1JTQ (1843km) and UR/SWL56 (2283km). Generally, running very low power results in fewer reports but not really fewer reporters. The active stations get you weaker and less often.

10 USA reports running 50mW on 10m WSPR
I think 10m has closed for me to the USA for the day. I'll leave 10m WSPR running a little longer just in case. At 2010z, 10 reports had been received, all at 50mW and all from stations in the USA. This was an interesting experiment as I know my antenna is not the best. 500mW seems almost like high power now!
The FT817 was set at 500mW and a good quality rotary attenuator (set to 10dB insertion loss) added as close as possible to the rig, therefore producing 50mW into the antenna lead and antenna. Because the cable will have some loss at 28MHz (1dB?) the actual radiated power will have been a little under 50mW.
UPDATE 2100z: The 10m band has definitely closed here to the USA. Only G4IKZ (local) spotting me now. at 50mW.

USA (again) on 10m WSPR and daytime MF
The first stateside station copied on 10m WSPR today was WG2Z (5600km) at a decent -10dB S/N at 1202z. I think this is a little earlier than yesterday?
UPDATE 1210z: I was on 472kHz until I QSYed to 10m WSPR. G3ZJO is a very decent signal now on MF. For example at 0922z he was around -15dB S/N. He has been even stronger, which for 10mW ERP is excellent.
UPDATE 1250z: The first USA spot of my 500mW today as by WG2Z at 1218z. Not long after I was spotted by KC2GMM at -17dB S/N at 1228z. USA stations spotting my 500mW WSPR regularly on 10m now.
UPDATE 1504z: Tomorrow I may try 10m WSPR with a 10dB pad in the antenna lead so ERP will be about 50mW, but RX 10dB deaf too. No I'll try it NOW! Looks like 5mW (or less) would be enough with W3CSW.
UPDATE 1754z: 8 USA reports, so far, of my 50mW and, even with a 10dB pad in the RX lead I still copied G0LRD (25km)'s 50mW and W7CNK's 5W (7458km).

54 stations on 472Hz WSPR
This evening (just now) there were 54 stations active on 472kHz WSPR. Several are shown as being on RX (including me!) but this may be because we've not been spotted on TX in the last 10 minutes.
UPDATE 2252z: IW4DXW (1190km) has just been spotted here on 472kHz WSPR.
UPDATE 2306z: Will be on 472kHz WSPR overnight.

472kHz WSPR
Since 1900z I have been back on 472kHz WSPR using 5mW ERP. So far, spots given and received, have been from the usual G stations. Let us hope for some new spotters tonight!
The Radio Hobbyist VE3CNU
See https://www.youtube.com/user/ve3cnu. It is always fun to take a peek into other people's radio shacks. This YouTube channel is hosted by Canadian VE3CNU. He has a nice shack and some nice gear.
I am amazed by how much money some people seem able to spend on the hobby. This is, of course, a very individual decision and I am not criticizing anyone. Some pay a lot more to play golf, for example.
What I would say though is the hobby can be enjoyed on a shoestring if you build simple QRP radios and/or buy good second hand rigs. My own approach has been a mix of some homebrew and a few commercial rigs.
Others prefer to buy their rigs new (often with long guarantees) and experiment with antennas and peripherals. This is a very individual hobby that can be enjoyed in a number of ways.
Others just enjoy chatting on the air.

ARRL 10m contest - mid December
As I have missed the CQWW SSB contest for 2 years now, I hope that I can be on for the ARRL 10m contest, Dec 13-14th. This contest lasts the full weekend and is all mode. As 10m is my favourite band of all, this should be a good one. As far as I know, we are free that weekend. I rarely enter contests to win. Rather, I enter HF contests to work new DXCC countries, or states and Canadian Provinces. I am no real DX chaser! My entry (if I remember and assuming I am free) will be strictly QRP as I have no gear capable of more than 5W pep.

Back on 10m WSPR since 1154z
Since returning from a small hospital operation, I have been running 500mW on 10m WSPR again. Best DX on TX is 4X1RF (3519km) at -20dB S/N at 1206z. On RX VK5MR (16144km) is the best DX so far.
I was in Addenbrookes Hospital, Cambridge, this morning, to have my stomach feed tube (PEG) removed. As I was sedated it was totally painless. My worry beforehand was totally unnecessary. I think I fell asleep as, apart for the initial things on the op trolley (being sedated by cannula into the back of my hand and insertion of my mouth guard) I was unaware of everything until I was recovering afterwards. Another stroke milestone for me. Still get giddy when walking, tired and speaking is hard work. Unthickened drinks are not easy. But I can eat most foods, all by mouth and, gradually, things are getting better.
UPDATE 1706z: 23 unique spots of my 500mW 10m WSPR signals, the majority being by stations in the USA with best DX KD6RF (7522km). It will so be time to QSY to a different band.

CQ WW SSB Contest last weekend - who forgot?
Darn it! Yet again I forgot this most excellent contest last weekend, although I would have been very restricted as we had our little grandchildren staying. They take priority. I must try next year. Last year I missed it as I was in Addenbrookes Hospital still very ill. The last time I caught it was 2012.
Although I do not much like contests, this one is always a good test and I often fill a few logbook pages with DX contacts. Exchanges are simple and quick. CQWW is usually a good way to increase the DXCC score. I always use real QRP power.
I dislike CW contests as they are too much like hard work. On SSB you can usually work stations, even with 2-5W QRP, especially later on when the big stations have already worked loads and are glad of extra points.

Stateside on 10m
The first stateside station was NU3E (5663km) at 1204z. My 500mW was first spotted in the USA at 1232z by KZ8C (6290km) at -28dB S/N. This is a little later than yesterday, but at least it continues a long run of stateside openings on 10m WSPR.
UPDATE 1315z: Spotted VK on 10m 3 times this morning. Best DX VK5ST (16214km).

10m and European stations
Looking at my 10m WSPR results, there seem to be as many Europeans spotting me and being spotted here as in the summer Es season. The traces don't look like backscatter, so I wonder if this is Es still? Whatever the mode of propagation, there is no shortage of Europeans on 10m.

10m 500mW WSPR since 1022z
I've just QSYed back to 10m WSPR and in the very first reception period CX2ABP (11127km), F4CWN and GM4EEY were all spotted.
In my first TX transmission at 500mW I was spotted by LZ1OI (2153km), UR/SWL56 (2283km) and UA3ARC (2436km) as well as by local G4IKZ. 10m seems in decent shape.
UPDATE 1037z: VK5MR (16144km) was spotted about 5 minutes ago.
UPDATE 1045z: Just noticed I was reporting the power on 10m I have now changed this to the correct 500mW although I'd been reporting that I was using 2W, wrong which was not right: it has been 500mW all day on 10m.

Early USA spot on 10m
WB1FIG (5304km) was spotting my 500mW very early on 10m WSPR today at 1116z. As far as I recall, this is the earliest so far this autumn. Conditions look pretty decent on 10m so far.
UPDATE 1547z: My best DX WSPR spot on 10m so far with 500mW from the FT817 is WB5B (8238km) at 1526z.

Back on 10m WSPR
Yesterday I remained on 472kHz WSPR all day, but today I have moved back to 28MHz (10m) during the day running 500mW from the FT817. So far it has been all Europeans spotting me, but the reports are coming in from right across the continent. On RX here, I am copying as far as Australia.

Sunspot count today has climbed back to 138 but daytime 10m conditions are again forecast to be just "fair". Nonetheless, I was copying VK2EMA (16558km) at 1016z on 10m so the band is certainly supporting long distance F2 propagation.

472kHz today.
Today I decided to stop on 472kHz all day and not QSY up to 10m. PA3ABK/2 (306km) is yet again a decent daytime signal with me at around -9/-10dB S/N. Spotting me so far it has just been the usual locals and semi-locals. This will change after dark when more distant Europeans should copy me.
In the last 2 weeks 27 different stations in 7 countries have copied my 5mW ERP on 472kHz WSPR. My all time list of reporters from this QTH on this band is even higher as GM4SLV (896km) is not included, and possibly others too.

Sunspot number dropping
Sunspot number dropped to 78 today and 10m daytime propagation is "fair". Checking on WSPRnet I see that 10m opened to the USA again today starting well before lunchtime for European stations, CX2ABP has also been copied in Europe. 10m is in decent shape yet again. I have not been on 10m today.
