Summits on the Air Expeditions in Korea

낏대봉 no-namer & the 5단GP


Today we had some business to take care of in Jeonju, me picking up a book, my XYL learning some hanji techniques. What a perfect opportunity to tackle a nice short summit nearby…I can be in and out in just the afternoon. HL/JB-155, a no-namer with no precise altitude known was a prime candidate, to find out some answers.

Mistake number one: just because it’s a lowly no-name one pointer doesn’t mean it’s going to be a nice, quick outing! Getting out there was easy enough, it’s not even a five minute drive from the Hanok Village in Jeonju, where turning off the 17 before it meets the 21 to go up a small valley I stopped to ask some locals that were hanging out just what is that there hill called? Ggitdaebong was the answer. Big help that is, as it’s one of the generic hill names that one can often encounter in Korea. Whatever, I’ll find out better, perhaps, if there’s a marker on the summit or something. (none of this info is on any maps I could find, and the summit height isn’t marked, but some other arbitrary summit height is marked, etc)

I continued up the road past the smallish reservoir as far as I could go, ending up at one of a few grave sites. Normally there are trails in these areas, and there in fact were. I took one that led to one of the other sites, trying to go up as quickly as possible and avoiding detours, as I had gotten pretty close (~700m lateral distance) to where the summit was. (Mistake #2, the closest start point isn’t necessarily the easiest or quickest).

Heading upwards on the trail which was, in fact, going in the complete opposite direction of my goal, I turned off onto another track leading directly up. Just barely a track. Luckily the undergrowth hadn’t started in quite yet, but the ground wasn’t terribly firm. After some ways, I did hit what looked to be a main trail, especially since it ran along the ridge line. This kind of trail would’ve been more convenient to have found at the bottom (wherever that may be, still being unknown at this present time).

Progress now was much more quickly paced, until I got within 50m altitude of the AZ and a junction, the choice to go towards the highest summit (and descend to get there) or up to this particular summit. I chose the former, though now I wonder if the trail would’ve been better if I had gone by way of the latter….the trail itself wasn’t an incline rather ran along a steep incline so it was a foot track barely one body wide, easily eroded, and not very clear. To make a long story short, at some point I had to scramble up to the ridge to get back on top of things, displacing more topsoil than I really felt was appropriate.

Afterwards, I was back on the fast track, walking along something definitely more worn, even passing a junction that I believe goes down to the temple on the north side of the hill. Then I found the summit, even going to the next mini-bong to make sure that it was the real summit. Surprise, surprise, the actual height of the summit is higher than our original estimate that went into the database, clocking in at around 502-504m ASL. Following that nasty-ish hike up, it was a rather pleasing discovery as I feel if someone were to make all that effort to get to the top and only claim one point it would be wrong. So, when the next ARM update comes out, the scoring, name, as well as lat & long for HL/JB-155 will be adjusted accordingly.


Seeing as one of the goals of this particular trip was also to test out my newly built 5 segment collinear antenna (5단GP) for 2m designed by M0GIA (ex. M3FVB). His design was originally for a 4 segment antenna, but figuring I had a ten-meter pole with which to raise it I could lengthen it by one segment, also as I wanted to construct it from one single wire and the length I could get my hands on was 10m long, it was just long enough for five radiating elements and four phasing segments.

As the wire wasn’t very stiff, I formed the phasing elements with plastic from some cat litter containers (the green portions in the photo above of the antenna). The matching section is made of two segments of threaded stainless stock to allow for easily fixing the contacts after tuning. The wire itself is .75mm2 stranded copper (~20 gauge?).


I set up the 5 segment antenna alongside the 2 segment Diamond NL22 (8dB gain, no ground plane mobile whip), for comparison (additionally I had an extra HT for reference.) Like I said, I was expecting an easy hike and for the testing wanted to put forth all possible conditions, otherwise I wouldn’t have brought three rigs! ㅋㅋㅋ

At first CQ I started swapping things around while talking with DS4OVT in Gimje, though honestly he wasn’t paying too much attention to my outgoing signal and was more distracted by the differences in how the different rigs’ mics sounded (once again, the VX-170 gets dissed😦 though that was in comparison to the FT-857’s stock mic (just wait until I set up the base station with an SM57!) however in some of the operating conditions it sees I’m not going to mod that mic and decrease its water-proofed-ness). I’ll have to have somebody on the receiving end record throughout testing next time to see with my own eyes what’s going on.

Post Script Edit:

The following Monday (May 16) I took the 5단 GP to HL/JB-168 for a spin, with only 5W DS3OMA was receiving me 52 (and I he 55 with his 10W) in Daejeon, 45km away. However, just the other week, June 15, using the Diamond 2 segment mobile whip, I was receiving him 51 (no changes in his system), and he I at 52, yes, still the same report for my signal but I was putting 50W into that antenna! In the first case, I did stretch my legs in testing with him up to 50W which he says did peak at 59, so that must indicate something done correctly with that antenna!

Anyways, between making some more QSOs on 2m, and then some on 20m (with a 100-anny Taiwan station, not my first, not my last!) and back on 2m again, I made a contact to remember with DS4GOD on HL/GJ-001 무등산. The kicker is this: normally the top 200m or so is closed off, being a military installation and all, so unless you’ve got connections, activating is out of the question. Well, today, for the first time in 46 years, during a six-hour window, the general public was allowed to reach the summit and it was at this time that I had a contact with DS4GOD as he was on top of this mountain. I’m so jealous–had I known ahead of time, I would’ve gone down there myself to activate! Either way, I caught some “SOTA DX” thanks to him!

I packed everything up while waiting for DS1SED/p4 to reach the summit of HL/JB-017 운장산 (I had already heard from him on his way up) to make a S2S before heading down on my own. We had our final contact, agreeing to meet later on in the evening as he’d scooter on back to Jeonju quickly enough after he activated (a last minute affair, on his part).

Playing it safe, I decided to take the beaten path down (knowing there are cliffs if I were to attempt a “direct descent” bee-lining to the car. Heading east, around the rim, it wasn’t too bad, nor was I worried with the adequate lighting I had on hand. It was more a matter of not taking too much time to be back in town to, like, eat, and stuff. Well, after making my way down, going under the newly constructed 27 expressway (Wanju-Suncheon) I arrived at the village just to the south of where I originally drove through to get to the trail head. As chance would have it, there was an old guy walking out of his house, heading right on over to that next village to have dinner at his son’s house. Well, ahem, he just couldn’t keep his hands to himself–groping towards my privvy-parts and asking me if all “Americans” were this “well endowed.” I dealt with this for about the five minutes it took to get back up to the other road with which I was familiar, discreetly fanning him away, listening to him explain how his son studied abroad, how he’s the same age as me (not the old guy!), etc. I did make it back to the car, and headed back into Jeonju to a schnitzel joint to dine with my XYL and some Parisians she met at the hanji shop.

2차 was meeting DS1SED to hang in a 휴게실 out in 효자동 for some beers and squid (outside of which was that tree converted lamp post you see up and to the left). It had been a while since last meeting, so was enjoyable. Going back home we took the 나티 대리운전 service which was more comfortable than the normal joe’s you call to grind your gears and get speeding tickets for you.
