Long Knoll G/SC-007 - decent condx on 10m

I’m currently in Wiltshire for family reasons, but brought my gear with me. There are only 1 pointers within reasonable driving distance of our base in Potterne and I selected SC-007 as being the closest. This has been activated many times but I noted from the reports that parking could be problematic, particularly from the East, so I decided to go up from the West, using the path that starts from a single track road called Coker’s Lane and did a scouting trip the day before to check things out.
As well as the small space beside the church in Kilmington, described in the recent report by M1MAJ/M3ZCB, I noted 2 other possibilities - one outside the house called Highlands and a small space by a field entrance just down the road from that one - see map below. While exploring though, I approached a local resident and asked about the possibility of parking on their property; while initially negative, as the conversation progressed, they relented and gave me permission as I wasn’t local and I promised it was a one-off and wouldn’t advertise it - excellent result.

Parking spots marked P in red; the one I actually used is not marked, in keeping with my agreement with the local resident.

Saturday 19th had a good weather break forecast between heavy rain days and so it proved. Nice and sunny all day with very little wind. The start of the path at Coker’s Lane is wayposted and from there it is a short walk across arable fields, through another gap in a hedge and then over a wooden stile next to a dead tree. Just before the stile there is a false track which leads nowhere, with an overgrown waypost next to it.

The Stile


It is then a short but steep grassy climb to the top, with the walk taking approx 30m in total.The area with the hill had a few cows in it.

Activation
KX3, Sotabeams 20/40m dipole, 2el yagi for 10m, Spiderbeam 7m mast, 6m al mast

Started on 40m at 1050 utc with M1DDD first in the log. Another 12 G and GW stations followed, with just one EU chaser HB9JOE. One of the Gs was Scout Jamboree station GB2CSG operated by Peter and I had exchanges with 3 scouts -Francesca, Michael and Alec.
Switched to 10m which was open to USA and picked up KC8QDQ in Ohio who was calling CQ. A spot then brought a short skip QSO with Robert GW0RQC in Cardiff, followed by SV2HJW, 2 East Coast US chasers, and then another short skip to Wales. Things went quiet, so I went down to 20m, first for a S2S with OK1MCS/P and then a spot run of 11 EU including 4 more S2S.
Another spot on 10m brought just 2 chasers, WY7N in Maine and a S2S with MW0LEP/P. Got another S2S on 20m and then had a short lunch break.
Going back to 10m at 1241 utc, the band started to open well to Stateside, with 7 US chasers incl Illinois, Michegan and Wisconsin. When things went quiet again, I browsed the band and found PX0FF the Fernando de Noronha DX-pedition and got them 2nd call - easily the most exotic DX of the day.
Another spot brought 3 more US chasers and 2 from Greece, including Dinos SV3IEG. I then got a S2S with AJ2I in New Jersey and then the best S2S of the day with K2CZH in Missouri, followed by Adele ZS5APT. Denis, MW0CBC called in at 59+ - really good skip to Wales it seems(altho he was running 800w to a 10el LPY) and we had a brief chat about his forthcoming trip to Scotland. Staying on 10m then got me another 7 NA, EA8 and 2 more from Greece, with VE3PQX being last in the log.
I packed up at 1415 utc with the threat of showers coming in but they bypassed Long Knoll and I could probably have stayed QRV longer.
65 itl for the day. I only saw one hill walker all day.

73 all.

Nice to have a proper QSO with you, Simon. Some good suggestions for my forthcoming Scottish trip next month and I’ve emailed Fraser as you suggested.

Have a safe trip home.

Cheers

Looks like you got the best of the weather, and some great contacts!

Next time you’ll have to persuade the locals to carry your gear up too :sweat_smile:

Great activation with numerous NA QSOs and even SA! Many thanks for the report and photos. If I activate that summit again I think I’ll look at a western approach. :slight_smile:

What Yagi are you using for 10m? Is it home-brewed or a commercial product?

Thanks for the S2S. Groundwave, I figure. For me, 10 metres was either very close or over 2000kms (so mostly trans-Atlantic). I was using a flowerpot vertical dipole for 10 metres. First outing it’s had, though I made it months and months ago…

Home-brew, based on the tent-pole yagi described by VA7BIX on his Hamjazz Youtube channel.

Groundwave
[/quote]. We were about 55 miles apart, which seems a bit far for groundwave according to Mr Google. All my close-in contacts were with S Wales at about the same distance, so possibly localised eS?

https://www.scadacore.com/tools/rf-path/rf-line-of-sight/ suggests it’s a simple line-of-sight path, so I doubt any ionospheric involvement. It’d probably have worked pretty much as well with a V/UHF HT.

Conversely, the radio paths for my contacts with 2W0ILQ and MW0SAW needed to find a way around some solid geography.

Yes, I guess that could work, although this profiler UK Radio Line of Sight Surface Elevation Profile Generator gives a rather more pessimistic view. Hopefully I’ll get another chance to get some short skip contacts on 10m from another hill in the area while I’m down here. Always interesting to find what works. I’ve had a few backscatter contacts in Scotland - could only hear weak G stations by beaming North.

I wasted a bit of time playing with HeyWhats that, and while G/SC-007 Long Knoll isn’t quite visible from GW/SW-025 Cefn Eglwysilan, Brimsdown Hill (not SOTA) not so far away is. I figure 10 metres RF would find a way without invoking anything ionospheric.
Take a look at HeyWhatsThat
The profile parameters allow you to try different frequencies over a selected path. (Sadly, the shareable link doesn’t remember things like the other end of a selected profile line, so you have to find Long Knoll all over again… :confused: )
