No mast? Want DX? No Problem!

A comedy of errors, or getting away with it

Alex @GM5ALX had planned a Friday day out. Nothing out of the ordinary, just knocking off half of GM/ES summits, as he does most Fridays. It didn’t take much for my brain to parallel process and calculate I was owed a half day, and I could nip up Kerloch GM/ES-057 to catch him on one of his summits.

Alex then suggested I try my new AliExpress Telescopic HF Whip. Ok, I said. I hadn’t even taken it out of the box at this point.

Friday 31st January 2025
I set off for work, with my SOTA bag in the Landie. Inside was my usual soft case containing the KX2, 41’ wire, 9:1, some pegs, velcro and other bits and pieces. I also carried the new whip, base, spike, and radials. No mast needed today!

The day started well. I was able to chase Alex from the work’s car park when he was on GM/ES-049 Ladylea Hill.

Later, I left work heading for Kerloch and was able to chase him on his second summit, GM/ES-053 Ben Newe, but only by driving in the wrong direction for 2km and finding then stopping on the only 4m stretch of the road where I could hear his signal. A metre either way and he was gone. All good, and I turned around, heading for the Kerloch car park.

The Ascent
Striding up the nice level and smooth gravel road, I passed several chaps from the model flying club, who were enjoying the still and sunny afternoon. It was one of those chilly days with a warm sun.

The track climbed up through plantation and then I needed to turn off up the hill path. Storm Arwen (2020) wrecked this path, eroding it badly, with many windblown trees.

Well, I was pleased to see that most of those trees had been cleared, only to be replaced by new ones. The path, however, had deteriorated further, with deep gullies and more large boulders than Number 5 Gully.

None the less, I made steady progress. And then I stopped in my tracks! Not because of any blockage, but because it suddenly dawned in me that I hadn’t brought any coax to connect the HF whip to my radio. I sent a WhatsApp to the group. I needed to qualify this on 2m. Chris @2M0RVZ had planned on going out but said he’d hang back. That helped.

I charged on, dancing over the boulders that protruded like islands, from the iced upper path. I exploded (literally) on to the summit, out of breath, but no cramp this time!

The FT-3d on my shoulder strap announced my presence via APRS. My activation weapon, however, was to be the Yaesu ft-60r, complete with VHF/UHF RH-770 telescopic whip, or so I thought…

Things went well – a summit to summit with Alex on GM/ES-047 Pressendye, followed by another S2S. Well, it was Alex again, but this time with the GM/ES Society club call GM0ESS. I worked @MM0RFN and only got 2/2, much weaker than usual from here. Chris @2M0RVZ was 41 and gave me a similar report. Simon @GM4JXP was strong, but he was pointing his ft857d-powered yagi straight at me.

I still had the ft-3d turned on. I could hear Chris work Alex and they both sounded much stronger, despite this radio just having a whip. Mmm…? I’d been on .550 and they were on .500. Sometimes 2m can be funny like that. I moved on…

With the summit qualified and with 30 minutes to kill, I took another look at the AliExpress HF whip. I wonder….

Five minutes later and I had the whip extended by a couple of metres, with the base stuck in a red bull can that was in the trig’s hole. The 41’ wire antenna was looped over the top just below the tip. I hooked the low saggy wire up to the KX2. Would it tune on 20m? Well, it had a wee think about it but produced a 1:1 match first try.

I put out a spot and hoped for the best. It didn’t just work; it worked exceptionally well. My new inverted V with vertical section brought on a pile up, with the frankentenna giving me stations in England, across EU and even Africa, thanks to @EC8ADS Alfredo, in Las Palmas!


22 on 20m SSB and 5 on 2m FM

Pile up subsided and time to pack up. I had to be in Banchory for the dentist at 1630. I was just under an hour on the descent, arriving back at the Landie around 1605. Ten minutes later I was pulling up to the dentist.

Aftermath

APRS Mystery
Only when I was driving home, did I notice an APRS message on the ftm-400 in the Landie (MM0EFI-9). It simply said “amateur,” which is our little jibe we use in the group when someone screws up. It gets sent almost daily, to be fair, usually via Whatsapp. It surprised me because I thought Alex would have sent it to the handheld (MM0EFI-7). A later conversation revealed that he did. His message was picked up and gated by MB7UAB, to the east of both of us. Neither of my Yaesu’s have TNC’s, so wouldn’t re-transmit a packet. The RAW message on the HT was brief, however, the one in the Landie mentioned MM0EFI-7 at the bottom of it. Answers on a postcard please?

Poor Signal Reports on VHF
1900h and I’m back in the bothy unpacking my stuff. I pull out the ft-60, still attached to the RH-770. Except it looks strange. It doesn’t look like an RH-770. Closer inspection reveals it is not an RH-770. No, it is a 27MHz whip.

I am, indeed, an amateur.

Great results with your new top-fed vertical?

As we know, a 20m inv-vee with the apex around 20ft has a polar pattern much like the shape of an orange. As the height approaches 30ft, the pattern changes towards the more-familiar broadside figure of 8.

But most SOTA 20m inv-vees are likely closer to 20 than 30 ft high, so it’s the orange.

We also know that NVIS propagation works on frequencies up to around 30m, but it’s not something associated with 20m.

As such, with our 20m inv-vee at 20ft, where does all the radiation at elevation angles above 45-50 degrees go?

Up to the ionosphere no doubt, but is any of this reflected back, or taking a chordal-hop to places far away?

Probably not … ?

On balance, one could be tempted to conclude that a significant proportion of the transmit power going into a low 20m inv-vee is lost / wasted?

Perhaps, that’s why the ‘auxiliary vertical’ worked so well?

RF has got to go somewhere…what a fun day… amateur :crazy_face:

My day was surprisingly straight forward with no issues or anything…well perhaps one. I did have some concerns when driving to Ladylea and droves of tweed men with hounds were scratching around with shotguns looking for turkeys or something. Luckily they were a couple of hills over and I wasn’t going to get shot.

It seems anything west of Morven was covered with snow and Ladylea was one of those. The main concern was parking, and not being able to get the car out once I returned to it. So I just parked on the verge pointing downhill, even though there is a nice off road parking area.

Both Ladylea (GM/ES-049) and Ben Newe (GM/ES-053) are short ascents along straight forward paths to the top.

There was no wind whatsoever and the wire didn’t even flinch on the mast. Whilst it was chilly it was very pleasant in the sun. The clouds were over the high peaks and it gradually moved east during the day. I kept mostly ahead of the cloud but by Pressendye it was no long the brilliant blue skies with me. Fraser was still okay being further east still.


I decided just to do 40m and 2m today and both were active at an easy pace.

In the way down from Ladylea a path leading straight down was too tempting as a shortcut - especially as I still had two more to go. I looked at the map and whilst the path didn’t return to the road, there was just a short stretch of forest to walk through.



Scooting under a gap in the fence and then over and under endless fallen trees until finally coming out into clear forest. Not sure if it really did save any time. Off the Ben Newe.

There had been a couple of jets flying around this morning, especially when I didn’t have my camera ready. This was the best shot. I’ll leave you to find the jet.

Ben Newe has a nice summit with trig and bench seating. I kept hearing 2m squelch break but no one was there. Eventually Fraser appeared but he couldn’t hear me when I replied. Eventually we got there and then he was off to Kerloch. I still had HF to setup, work, dismantle, descend and drive to Tarland, if I wanted to coincide with him!


Off to Tarland, or a parking spot just north of the Douneside Hotel, following random tiny roads Google Maps was taking me down. Fraser had already setup and whilst his route was slightly longer than mine, I was feeling the pressure to catch up and absolutely legged it up the hill. :face_exhaling::hot_face: Also managed to get lost in the mountain bike trails and having to just tramp across the middle of it.

Managed to the top and called CQ just as Fraser was setting up. After 4 on 2m I decided that was enough and headed back home, I needed to pick up the kids from swimming etc and would be nice to have a cup of tea and get changed first.


A good 15 points, three new GM/ES summits and a complete for me.

Plus a good laugh at a friend’s expense.

Dave, Thanks for sweating this one out for me. Except, it was a 41’ or 12.5m "random, with the apex ⅔ along from the feedpoint.

I’d like to think that the close coupling (no electrical contact due to insulated wire) contributed to the DX. :blush:

Ah, that eureka moment when you realised the whip could be used as a pole… a much better solution than the ground-mounted antenna that I suggested. Not sure what you should have written on your tee-shirt for that one… “Amateur No More”?

Well done on the activation. It was a pity I had to go out on transport duty and missed the action on 20m. Hopefully next time you are on a summit.

73, Gerald

Oh, that’s a good result then!

Re: the 27Mhz whip. I just chucked it on my antenna analyser to find the SWR at 145Mhz.

Thanks for the excellent story, Fraser. Well done on your resourcefulness. It’s always good to be reminded that all may not be lost when we have that “Oh ****!” moment

One of the best!
