The Gaick Corbetts

Two days, five summits and a happy coincidence

Monday 30th June 2025
I had a motorsport meeting to attend in Kinross at 7pm. I decided to make a day (or two) of it. I left home at 0815 and arrived at the lovely Fife village of Falkland around 2 hours later. I set off on a round of the Lomond Hills. Until the day before, I thought there were two - West Lomond GM/SS-154 and East Lomond GM/SS-198, otherwise known as the Paps of Fife. It was only while leafing through my new favourite book, Scottish Hill Tracks, that I discovered that Bishop Hill GM/SS-187 is also a Lomond hill. There are still thankfully only two Paps though.


West Lomond

My route took me up through the delightful Maspie Den, then onto the moor leading to W. Lomond. From there, I headed south over moor and rough grazing to Bishop Hill. Finally, the long hike back east to East Lomond and the steep descent back to Falkland. It was an interesting, if long, amble among some nice landscapes. Very different from the usual for me. I activated all three summits on 2m FM, and had a bit of spare time on the last one for a spot of HF. Around 6.5 hours, 15 miles in total. Has anyone else done these three in a day, I wonder?


the long trek from Bishop hill to East Lomond

Alex @GM5ALX messaged me. He was planning on climbing the remote and rarely activated Munros of Carn an Fhidhleir (Carn Ealar) GM/CS-027 and An Sgarsoch GM/CS-024, and would I like to come. No was the answer, and not because I’d already done them twice, but because I was mulling over a possible Tuesday expedition of my own. You see; I had the Land Rover down in Fife with me, and that was for a reason. I had my bike in the back, and I had recently added “1 person camper” to its list of abilities.

All good, and on to the meeting. It was a post hill rally wash-up meeting and took for ever. It was 2215 when we all left the hotel. I jumped in the Landie and headed north. An hour and a bit later, I parked up at the last possible place it is possible to get off the A9 Perth to Inverness road before it ascends the Drumochter pass. I chucked my bike out of the back, rearranged a few things and settled down for the night. It rained heavily.


camp, above the letter ‘w’ of Snow

Tuesday 1st July
Up at 0715. Porridge, cereal bar, coffee + tea, packed and away by 0835. I’d camped at NN 72408 70183, so just had 200m to cycle to reach and then cross the A9 road. I was then on my way on the 5 mile/8km cycle up the ancient Gaick right of way and to the Corbetts of An Dun GM/CS-069 (827m) and A’Chaoirnich GM/CS-057 (875m). These hills had only seen three activations and the last one was 10 years ago.


the initial track. Gamekeeper viewing deer from his 110

The track was rideable all the way, undulating in places but never too steep. It followed the Edondon Water, crossing it a couple of times. After about an hour, I reached a deer fence and parked the bike. I was using a Walkhighlands route which did a big loop of the two hills, and this is where the return leg joined the outward one.


the Walkhighlands route goes clockwise from the south


closing in on my summits

From there it was a further km on the track and then continuation by path, with a bit of bog hopping. An Dun reared in front of me, a grassy castle, showing little weakness in its fortifications. I plodded up and aimed for grass, trying to avoid heather. I glanced up to see a hiker above me. Didn’t expect that. He’d found a path. Introductions done and we climbed together. It turns out he graduated in electronics a few years before me. We swapped stories about RF, solar flares and SOTA, and his work on the first Phillips CD players, silicon wafers and getting their IC rejection rate down from 78% to 35%.


An Dun GM/CS-069

All of this helped us both with the lung bursting climb. Suddenly it eased off and even more suddenly, we were at the cairn. He went back the way we’d ascended and I asked if he was going on to do the other one. Yes, was the answer but he was going to return to the valley and climb it from the south, rather than do the much longer loop to the north. That got me thinking. I’d tried to synch, my times with Alex, but I had a much longer (7km) hike to the next one, versus his 3.5km. A quick look at my map revealed that heading back the way I came would give me a 5km hike, albeit with a 340m drop, versus Alex’ 280m descent. Anyway, the numbers stacked up a lot better than my original plan.

I was QRV at 1050, so about 2 hours and 15 minutes after setting off, 40m was in decent shape (phew!) and I added 11 contacts to the log, before having a summit to summit with Alex on 2m FM. I was finishing my activation as he arrived to start his, aiming to give me more time to get across to A’Chaoirnich.

I set off down the ascent route, the narrow and faint path much easier to follow this time. For anyone planning this hike, aim for NN 71739 79430 on the way up. Below that is grassy and there is little evidence of a path.

The ground between me and the ascent of A’Chaoirnich was pretty boggy and broken, however the loch shore looked flat and more appealing, so that’s where I headed. I was only when I was half way around the loch shore that I made a discovery. There wasn’t any water flowing out of the loch to the south. The land to the right of me was the watershed and it drained into the loch. Loch an Duin actually drains north, and after a series of rivers and lochs, ends up in the River Spey.


lochside view

Anyway, I was aiming for a stalkers path that took a rising traverse south along the west face of A’Chaoirnich. A direct ascent looked ill-advised due to the steepness as well as a band of broken crags higher up. I gained the path and followed it south for around 500m. It wasn’t ascending as much as I wanted, and it was taking me away from the summit, so when I saw a gap in the crags above, I just went for it. A proper bit of technical heather climbing, with a few metres on the scree to see what that was like. It wasn’t good, so back to the heather. After 15 minutes I was out the top and onto the broad ridge. I headed back north, found a path and plodded up it.


up this. On reflection, not the best plan


at the top of the steep bit

After initial steepness, it eased off onto a massive plateau area, with the summit to the north end of this. When I arrived, Alex was already activating his second summit on HF. I set up my HF station and then posted a spot on 2m FM, with the only expectation being that I would work Alex. Well, it didn’t turn out as planned.


A’Chaoirnich GM/CS-057

The World’s smallest pile-up, with Gavin @GM0GAV and Jack @GM4COX calling at the same time! Then Alex from his summit, and finally Brian GM8PKL. Not bad, qualified the summit on 2m with just the Tidradio H8 and a telescopic whip. No further calls, so on to 40m. Again, the band was in good shape, with S2S to GW and DL. 20m had QSB but I still added a few more.


plenty of room up here!

Denis @MW0CBC whatsapped to say he was 20 minutes from his summit. I posted QRT but left the station set up and went off for a wander. A’Chaoirnich is one of those hills that has outstanding views, and I mean really outstanding. A 360° panorama of mountains. Not the best for photography, however, as the wide plateau takes up much of any shot. Still, a place to linger and soak up the scenery. Denis eventually sent me his frequency and we had an easy summit to summit to his peak Moel Llyfnant GW/NW-018.

I ate, lingered some more and then decided I’d really better head back. I’d been on top for about an hour. My descent followed the path until it ran out above a steepening, with bumps ahead of me and a ravine. Looking around, I found the top of the rising traverse path I’d used earlier, so I descended this, heading north again for a couple of hundred metres, before heading directly downhill towards the NE corner of a deer fence. This I followed west over some boggy bits and it took me back to the track. Knowing what I know now, this would be the best place to dump a bike, and it would have saved me the 1km of walking I did to get back to mine. NN 71731 78566 for reference.


panorama of my descent route through the glen

Bike and me reunited, I pedalled and free-wheeled back to the start in 30 minutes, arriving back at the Landie at 1545, so 7 hours in total. An hour or maybe 45 minutes could be shaved off of this due to time spent yapping to my new pal when I bumped into him a second time, and my extended stay on A’Chaoirnich.

Notes
Route - I think I got this mainly right. However, on my return to the glen for a final time, I could see that my scree and heather scramble probably didn’t save much time. The photo below shows the scree slope to the left, as well as the rising path, which ends up on the right at the bumpy ridge. It then doubles back up hill to pass near the top of the scree slope.

No 4G signal in the glen, but surprisingly good on top. However, I activated A’Chaoirnich from the southern end of the activation zone due to a faltering signal further north. I was prepared to spot via Iridium, but there was no need to.

Wildlife - newts, beetles, mountaineering frogs, grouse fledglings, Ptarmigan, Curlew and Dotterel were all evident. No deer, although there must have been some higher up in the glen.

Terrain - good Land Rover track, rough grass and heather, with short cropped vegetation on the tops. Not much wet bog. Much steepness though.

Midges - evident on the tops but only when I was near to the ground, operating my radio. I was wearing a thin hooded top I’d bought in the USA, from REI. The idea of the top is to offer full sun protection. Great for midges too. A quick spray of Smidge on my face and hands kept them away for about half an hour, which is as good as can be expected.

Summary
A contrasting couple of days in the hills. The Lomond hills left me feeling more tired than the Gaick Corbetts. Not sure why? Also not sure why these two fine hills don’t get more activations. They are only 5 miles from the A9 road. I guess the road is lined with lower hanging fruit!

Several reasons… few activators in the area. It’s only the last few years yourself and the other NE crew have appeared. Other activators were the few Inverness and North or the marauding masses of myself and others who live down in the Central Belt. As it is a wee drive to this bit of the A9 from the either us in the Central Belt or down from Inverness way, low hanging fruit often offer more bang per buck.

As you know, we were discussing some cycle routes I have planned for when my kitchen extension is built and I can get my bike out of the shed! I never asked about this pair as they seemed straightforward enough and I did think they’re deserving of an activation. What do they say about great minds thinking alike…

EDIT:

I’ve a feeling I may know this person and possibly worked with them in the past!

So that’s what the view is!
My (one & only) activation there was in clag from about half way up - one of the most miserable days on a hill I ever had (except for An Dun where I had cramp all the way back to the A9)

You wouldn’t have had cramp if you’d used the mechanical machine of Lucifer (in your opinion) AKA a bicycle. :wink:

It’s in exactly the wrong place for me too. The choice last night was to drive south to Pitlochry, over to Kirkmichael and up Glenshee to Braemar, finishing up down Deeside.
Or
Drive north to Aviemore, Grantown-on-Spey, over to Tomintoul and over the lecht to Strathdon, finishing up over the hill to Deeside.
Only a few miles and a few minutes difference either way. I opted for Aviemore because I’ve seen more than enough of Glenshee these past few weeks. It took me 2 hours. From your house, it’s 10 miles longer and 20 minutes quicker, so get on yer :bike:. :grinning:

Lower hanging :grapes: available.

Hi Fraser,
Good to finally catch you on GM/SS-198 East Lomond. I was too early for West Lomond and too late for Bishop hill.
Thanks for the comprehensive report on the hills off the A9. I go up and down it a few times a year and I’m always looking for SOTA to do on the way. Those two look like they are an all day affair rather than a “flyby” activation.
Interestingly, I work with someone who spent a wee while at Phillips and met the man largely responsible for the development of the CD. He tells a story that the size of the hole in the middle is based on a Dutch coin and the initial 74 minute capacity was based on the designers favourite classical piece !

Sounds like everyone who worked for Phillips is laying claim to inventing the CD player!

Philips had a big division in Southampton and now for small world stuff. Two of my work colleagues up here GM worked there. One was from London, one from Bearsden. One of them was headhunted to work up in GM, he recruited the other guy (who wanted to come back to GM) and I ended up working with both of them at 2 diifferent companies here. Talking about work they’d done for Philips, it turns out a third guy they worked with in Southampton was someone I went to school with. I bumped into one of these two guys on the summit of Schiehallion GM/CS-005 and the other on Ben Cleuch GM/SS-059.

Not everyone worked on CD… there’s a whole shedload of software people who worked for Panasonic up here in Edinburgh who were involved in development of the DVD filesystems and authoring systems. Never come across anyone who worked on Laservision stuff!

Gosh it all seems so long ago. Well it is… I saw, touched and heard my first CD in 1983, 42 years ago. It was a Sony player through a tri-amped (Naim NAP250s) into a pair of Linn Isobariks. Sounded all right ISTR

With the Sony, Naim and Linn combo, I bet it did and probably still does!

I started activating CS-039 then walked to An Dun (horrendous down & up) then had to walk back to where we had parked the car off the A9. Cramp in both thighs all the way across the plateau and descending to the car. If my son hadn’t been with me it would have been a MR job.

Still wouldn’t have used a devil’s contraption for that route

I remember a Uni trip to the Linn Factory where we were suitably impressed with the sounds. It was probably about 1984 as Linn had just recorded “The Blue Nile”. As part of the tour / sales pitch we listened to the sounds with and without watches on. It is probably just a placebo effect but I did think that the 80’s watch with a pizo alarm probably did ring slightly and affect the sound, but I might have just been impressed with the combination of the Sondek and Isobaric speakers… having got that sound test out the way we tried the next combination … a comparison between the “New” CD (A Sony player I think) and a well cut record played with the Sondek and I’m afraid I was in the minority that preferred the sound of the CD… Unfortunately my decision to go into a career in education and to continue to eat food meant that was the closest I got to a pair of Isobariks …

PS Frazer 40m wasn’t playing for the relatively shortish skip to NE England, I heard a whisper of you (22?) but nothing workable.

Lovely report Fraser for a lovely day out. I had a few options of which summits I’d do, and decided upon these two, GM/CS-024 and GM/CS-027, as some new summits for me, and not too much driving.


My route was straight forward, starting with a cycle from Linn of Dee past the redhouse bothy, over the Geldie burn, and to the ruined lodge. I did end up cycling beyond the ruined lodge, you could cycle to where the loop starts, but I’d had enough of the bike by then. I think doing Carn Ealar, the most westerly summit, first makes for a good route, if nothing more than it’s shorter to get back home once you’re done on the second!



The path is reasonable until you cross Allt a’Chaorainn stream at the low point before climbing Carn Ealar. This is a tramp across bog and heather until you reach the ridge and a path appears.


It was overcast but the clouds were high, and the air was still, so the views were excellent and summits were very comfortable. A few midge did make an appearance on Carn Ealar but not on An Sgarsoch.

As Fraser said, our timings worked out very well for some easy 2m S2Ss, so a good choice on his part for the change of route! I enjoyed similar conditions on 2m and HF. I did try 15m but only managed another QSO with Chris, F4WBN, who told me the band was dead for him. Brian, GM8PKL, asked me where I was. I did a terrible job of trying to explain and left it as “in the middle of nowhere”. I could hear Skye and Lewis on 2m having a chat with each other, but only managed a QSO with Gordon in Mallaig, GM4OAS, but I was just using the 5W HT and RH770.



Views from both summits were amazing, but An Sgarsoch, with a bit more height, was the winner. 360 views of all the cairngorm, and well beyond, summits, too many to name but definitely down to Ben Lawers, across to Ben Alder, and looking back east to Lochnagar and Morven. Morrone, and it’s communication towers, stood out and looked like a little hill from up here.

The walk back to the bike was a similar bog and heather bash, but at least downhill. A remarkably coloured rock looked like my bike and helmet in the distance, and that caused me to spend 15 minutes pacing back and forth looking for it, only then to find it much further down the path.

I’d cycled across two of the streams on the way out, and thought I’d try a third on the way back…well I managed 90% of it! :sweat_drops:

Whilst it’s a long way in total, 44 km, much of it was the cycle (around 30km worth) and that is a pleasant one. There’s only 170m of elevation over 15km on the way to the summits, so not too much work, and then the way back as a slight downhill to help you along. The hiking part is a good length and not overly steep. Those that do the whole thing on foot have more mental strength than I could manage!

Potentially, I’ll be back this way, next time going beyond Carn Ealar to the remote Corbett of Beinn Bhreac (GM/CS-045) and even less activated summit. Unless I combine it with Beinn Dearg from the south.

Off topic OM report :cd:

Off topic but seemingly relevant:nerd_face:

On a whim, I recently bought a CD, well three, in the form of the 40th anniversary edition of Brothers in Arms. Digging through emails I worked out that it was almost exactly 20 years since I last bought a CD, having given all that nonsense up for the amazing world of streaming music. Now actually listening to a whole album, I realise there are songs I’ve never heard but I actually really like. I’d put One World in my top 10 Dire Straits songs now, having only just heard it, even though it’s been around 40 years.

So the CD arrives…now what? My 3rd previous home server does have a DVD drive in it, and we have a bluray player in the lounge, but they’re no good. So A random USB HP DVDRW that was on sale for £13 arrives and a journey into EAC software begins.

But I don’t want to sit on the computer to listen to music…

Other people have made this very easy. Take off the back, and replace the innards with easily purchasable parts, and now you have a lighter, larger storage, long battery life music player. Custom firmware is available but I like the simplicity of the stock one.

But I have the CD

Given it was ÂŁ10, and supposedly works, I bought this Sony CDP-40 from 1988, yet to arrive.

It did start me down a very deep rabbit hole of CD players of years gone by, and reading about the Philips TDA1541 DAC - what the internet says you should get but unfortunately pushes up the prices of players with it. This rabbit hole is just next to the one that says just buy any recent CD/DVD player with optical out and a modern DAC and the sound quality will be considerably better, and you won’t be operating an old CD tray. Oh, but does the optical link truly carry the audio unaltered? :thinking: Maybe it’s better to modify your CD player if it’s real audio you want… :hole::rabbit2:

Oh, so much to comment on your wonderful report:

That’s the most accurate description of those two hills. The sense of isolation is unmatched. The fact that Carn Ealar is a source for three of Scotland’s major rivers affirms it is in the middle, at least. Did you see anyone?

Assume the heat had got to you? Top tip - waypoint it next time you leave it in the middle of nowhere on your way to the middle of nowhere.

Guy buys 1 CD, then goes down several rabbit holes, eventually spending a grand on hi-fi equipment to play aforementioned disc. The man maths on this checks out OK and it’s definitely something I would do. :grinning:

Brian’s QTH in Edinburgh is such that he is LOS to Ben Macdui and some other Cairngorm summits.

Some cyclists packing up at the redhouse, and walkers near white bridge, but not a soul near the summits. Linn of Dee car park was rammed when I got back.

Usually I can see my historical gps tracks where I’ve come off the path to stash the bike. The problem this time was that it was much further away and so not on my screen at the time. The mirage was so convincing, and I thought about walking straight to it, but decided to stick to the path, then went back and forth thinking it must’ve been hidden by a ridge or something. Uncertain, I kept walking back to the ruins.

it can’t be this far.

Narrator: It was.

I’m terrible for this sort of thing. Invent a problem, research it to death, spend a fortune to solve the problem. Realise it was never a problem.

However, I have only spent £60 so far and ordered some more CDs at least. The 1988 CD player is probably crap (on the audiophile scale of things) but I can live in ignorant bliss…until I get some new headphones and and and …:sweat_smile:

Whilst I know the sensible option is to use the iPod I’ve just spent £50 on, or maybe even the £10 (non TDA1541) CD player will be fine enough, but for completeness what model might that be?

Cairn Toul is his summit, with claim to fame being working a guy on CT, whilst Brian used a dipole on the floor that he was resting his feet on!

Brian is a great guy on 2m. Likes a yap. I hadn’t worked him for ages, but I think I worked him on my last half a dozen summits!
As for the Cairngorms, he told me he can see Cairn Toul from Edinburgh on around 20 days a year. He also told me he sometimes works his pal in Tain on Ĺłw, due to refraction over Ben Macdui.

He ran the 3cm beacon RX and used to stream the audio. The TX was at Chris GM3WOJ’s QTH just above Tain and ran around 1W. Just recently Brian has been in a few of my 2m SOTA operations, very useful last week as I was testing out a Flowerpot antenna on 2m.

Philips CD160. I think that was the first to use the TDA1541 and offer 4x oversampling.

I didn’t realise the 1541 had gained mythical status nowadays. Back in the mid/late 90s when I was toying with buying a Mazrantz CD63SE mkII everyone was trying to dump 1541 based players for Burr Brown equipped devices!
