Thanks for the contacts this morning on 80m Tom. In answer to Brian’s query, I checked the Chilton ionogram before Tom fired up & 60m would have been marginal at best, but might just have worked towards the end of the activation. I think the FofF2 was about 4.75 MHz so 60m would have been on the change by around 6:20z
Tom, I know we have worked on 40m CW before but I also know that at times we haven’t, but I will be listening anyway.
I’d have expected the figures to be the other way round with many more people working it on HF than VHF due to the greater range potential. But due to the good VHF takeoff over a high population density area, many people just treat it as a 2m FM only summit. Their success seems to lead to people ignoring it on HF when it looks like there are probably a lot of chasers looking for it but can’t hear it on VHF.
It is true that NW-044 is good VHF take off over a high population density area, but the fact that a number of Sota regulars also have used the hill during VHF contests such as the Backpackers slightly warps the numbers (something to do with stopping all day?). This is probably the case with a number of hills in the program. It is also a very busy hill and I personally would avoid doing HF at the weekend when the crowds might make HF dipoles more of a hazard, which is when we tend to get more HF contacts.
Hopefully there’s always going to be someone who has yet to work a common summit, because the popularity of SOTA is growing and will continue to do so.
Oops! I must admit I didn’t look that far back. I have certainly never heard you when I’ve been at IO92BA.
You did well in the AL
this week Walt. Would you not have been BP qualifying?
Thanks. That’s the first time I have ever operated /P on 50 MHz. I slung together the GW7AAV Delta Loop just a couple of hours before the contest. I was amazed how far I could get with 5 watts on the band. The stations in GI and Cornwall couldn’t hear me, though, despite the fact that they were good signals with me.
Actually, I packed up at 21:10 UTC because it was getting dark and cold. With hindsight, if I had stuck it out until 21:30, I might have beaten LZE!
No, I was not BP qualifying … I was operating from the car. I don’t like backpacking in the dark!
I am a case in point. I only work HF SSB since I have no VHF/UHF capability. Tom’s activation this morning on 80m SSB provided me with a unique and I have been involved as a chaser since Jan 2010. Thank you Tom. 73 Tony G8BVJ
Very strange conditions this morning, Tom was 59+20 here on CW & was the same on SSB over a distance of 70 Kms. I have tried to work Tom before on 40m & not mananged to, but today is the strongest I have heard him on the band.
The Chilton ionogram is not giving a reading at the moment but checking other sources I am baffled at the propagation between me & Tom being so good.
The band is obviously open for more distant contacts as Tom worked several EU stations, but he was the strongest signal I could hear on the band this morning.
Hi Mark, You were 59++ with me. Perhaps the skip was all wrong. It is a pity since I have never worked the Cloud on 40m SSB and I don’t have CW. 73 Tony, G8BVJ
I’ve come to the conclusion that the path between me & Tom was via Sporadic E,or more accurately E layer NVIS, if there is such a thing,hence the very strong signal over such a short path. It will not have been via the F2 layer otherwise you would have heard Tom as well as I did.
Friday 27th May 2011 saw my fifth daily consecutive Cloud activation of the working week. Another successful early get-up meant that I was QRV on 40m CW by 0550z. Ten stations were worked before things went quiet and I switched up 30kHz to 7.062MHz SSB. The next contact - with Mark G0VOF - was extraordinary, almost like a fully quietening 2m FM QSO with a station in the same town. It was then a pleasure to speak for the first time with David EC2DM, who I have worked several times on CW, including in that segment of my operation earlier.
Back on 7.032MHz CW, three more stations were worked, bringing the QSO count to 15 and the DXCC count to 10 - CT, DL, EA, F, G, HA, I, LA, OK and S5. My SLAB was flat, and I was working on 500mW by the end. I had a listen on 15m and heard a DX station working a pile-up - A7 I think it was. However, I just didn’t have enough juice left in the SLAB to call him or call CQ, so I packed up.
At this point the light rain became heavy rain, so I wasted no time in scuttling back down the hill. It was cold and wet, and my car heater was used on my drive to work. May? Ha!

MWIS is reporting temps of 1 to 2C at 900m and snow above 800m for Sunday. May indeed!
This mornings conditions on 40m were indeed very strange. As in my earlier post I can only assume there was some enhanced E layer propagation involved. I have worked you on G/SP-015 on many bands, but today was the strongest I have heard you, possibly with the exception of on 2m SSB when we are beaming directly at each other. For HF, with only 5 Watts at your end this morning was very unusual.
With the reports from Tony & Brian, & what I gleaned from the Chilton Ionogram & other sources, I think what must have been happenning is as follows.
Our signals, both ways were being reflected back from both the E layer & F2 layer & arriving back at our locations in phase, hence the their unusually high strength. At that time the E layer was just above 100Kms AGL & effectivly reflecting frequencies up to 10 MHz.
For Tony & Brian, the signal from your location could have been reflected/refracted by both the E & F2 layers but arriving at their locations out of phase, thereby cancelling each other out.
As I was further North from all stations, & running 100 Watts against 5 Watts, my signal would have arrived at Tony’s location via a slightly different path, where the phase difference was not enough to cancel out my signal, & any such phase difference would have been at least partially offset by the higher power I was using.
I may be wrong, but that is the most logical explanation I can think of.
In any case very strange, but very easy QSO’s on both CW & SSB this morning between G/SP-015 & Blackburn.
