Summits on the Air Expeditions in Korea

서울 Seoul

Aftermarket Ansan Activation

The second Sunday of the month is always a special one. Well, by the reasoning I’m about to present, technically every Sunday of the month is always a special one. It’s hamfest day! The second Sunday of the month just happens to usually be just a tad bit bigger and more bustling than the others, since it’s the hamfest (termed junk 정크 in proper Konglish) in Seoul, in the baseball field at Yonsei University. I like to go when I can, to pander the program and get people interested in SOTA.

Additionally, after this month’s market (July 10, 2011) was a SOTA presentation at the university, which HL1FB so graciously helped to get a room with projector for hosting the event and showing a power point presentation about the program.

Not only was that going on, but also since the main audience was the 6K0FA 청룡 Scout Troop, we planned a hands-on activity with HL1WOU (and DS2NED to help out) to make portable slim-jim antennas with the students for the 2-meter band which they could take home and use on their own hikes when operating portable.

After the antenna activity was complete, the scouts had another engagement to move on to, so I decided to head up the hill behind the University, HL/SL-008 Ansan, for a quick activation before what looked to be rain later in the evening.

It’s a nice short hill, one of the lower summits in the Seoul area, in what amounts to a city park for many who live on its peripheries. I went via one of the back access roads of the university to later descend on the opposite side by the metro station.

When I got up to the top, with a large stone tower and a few people hanging out, I thought it better not to set up the good antenna with all the dark clouds about, so I HT‘ed it so I could get out quickly when it did start.

Even more fun is that 6K2HVZ contact I had–was actually one of the scouts that had been in the group this afternoon!

Good thing I didn’t set up everything, as when I was finishing up my fourth contact, the umbrella came out! Eh, activation complete–hopefully next time it’ll be nicer out for longer. Back to the bus station it was, get a ticket and some goat cheese. Don’t see much goat cheese down in Jeolla, but we do see some goats sometimes….


Seoul On The Air 20110702

(See 6k0fm.net for the bilingual wrap up of the event, click here)

Big weekend! Thanks to a spark from HL2OLP about a month back regarding an immediate goal of his to activate all 11 summits in the Seoul Metropolitan area (fairly reasonable), especially since after a year of SOTA in Korea they all haven’t been activated yet (one would think that region would be the first to be “ticked off the list” for most given the local demographic.

Me thought to myself that along the same lines why wouldn’t it be possible to stick an activator on each of those eleven summits for an afternoon and make some QRM? Well, the idea took off, and while we didn’t fill up the region 100% we did create quite a racket!

We lost a couple of activators at the very last minute due to a quick date change (rain was scheduled for Sunday the 3rd, so we moved back one day to beat it), but there were also a few random appearances on the hills (not necessarily all in Seoul) but welcome none the less.

Another fun facet of such an event is the points potential, for everybody, not only a wide selection of activators to work from home for the chasers but S2S galore–it was basically a big party on the air–hell, even the cops came! DS1DAT was asked to leave the premises by the military police on HL/SL-004 Inwangsan (military area, open to the public six days a week). That’s pretty much a crap-shoot–nobody bothered me last year when I set up a big honkin’ Yagi up there in the evening (delivered that very same afternoon by DAT himself!).

I chose from the leftovers HL/SL-003 용마산 to activate with F4AAR Laurent–a hill which I had had yet to visit, not terribly low (though low enough to bring full QRO gear). F4AAR brought his newly acquired toy, an SDR radio (a Flex 1500) to do some testing in a hopefully less noisy environment than his flat.

We did have a decent party going on up there, a bunch QSOs in three languages, loads of S2S action, a bottle of red, a freshly made liver mousse as well as some garlic flavored frischkaese. Even though the kit was QRO, the majority of contacts were QRP, thanks to the 5 segment colinnear, we were reaching over into Gangwon-do and down into Chungcheonnam-do.


2차 was happening downtown at a nice charcoal grilled 닭갈비 place (friend’s resto) where propoganda and awards were given out to the top contact makers who showed up–a special edition SOTA hanji pencil cup designed and executed by N5ATY. DS1RDJ took the cake for the top activator (some might imply she has an unfair advantage, all the guys wanting to get a QSO with her….;) with HL1KFB coming in second of those at the restaurant.

After filling up there, we headed through a park and over to a beer joint for 3차, where the imbibing continued on well on after we had to go to catch our (almost last) bus back down to Iksan.

The consensus is that the event was a success, with a lot of people having a lot of fun, likewise with the meet-up afterwards to see all the various activators’ faces in person in one place. It’s safe to say that this will become an annual tradition every year in July for the HL SOTA Association’s birthday! See you next year on the air in Seoul! (Actually, probably much sooner than that…!)


20110618 HL/SL-002 관악산


What a full day! Taking the first and last buses to make three appointments around town, morning, noon and night–who says there isn’t any time to fit an activation in there, somewhere. Four hour window? No problem.

Taking the metro from 신도림 over to Seoul National University, I started on my merry little way, goal: HL/SL-002 Gwanaksan. This way takes you up the western slope, dotted with boulders, and on this dry day was actually quite fun to climb! I’m not sure I’d like to go down via the same route, but it was a fun ascent.

As it’s a bit less travelled, finding the trail head took a bit of a walk, but upon finding it there were no problems. It’s necessary to go almost all the way to the southern end of the campus, going up the Tal, seeing those college-esque sights so common on a Saturday afternoon–banners being painted, bands sound-checking for some performance that evening, though didn’t see any books cracked open on the quad. Those photographers must be very skilled to catch Homo studentis in that habitat…

Arriving at the summit, with weather radars and broadcasting equipment occupying the site, I had to search a bit to find an ideal transmitting location of my own “in the shade.” I finally settled upon a spot just 30 seconds down from the summit on the north side, off the path and under a big rock. QRM down below S3…good enough.

Travelling light and principally with other objectives for the day in mind, I only had an HT, but is certainly doable in the Seoul Metro area. I made seven contacts, easily enough, before realizing what the time was and starting my descent to meet my next rendez-vous for supper before finally heading back down to Jeonbuk. More interestingly, I’d be seeing three of those seven contacts in the upcoming weeks!

I thought I was descending towards the north where there was a subway station at the end of the ridge, but I actually was going east, going together with another group. The path was much wider and worn than that of the one I took up, I was at least halfway down before I needed auxiliary lighting to see, listening to the evening ceremony sounds of the temple on the opposing slope. This path took me right down to Gwacheon station, from which it’s a short ride with only one transfer to get to the Express Bus Terminal. Nice.


Namsan and the QRM monster

So, you say, he definitely didn’t get a full night’s sleep–it was after midnight when he arrived back in town, right? Then there was a taxi ride across the city from Seoul Station over to Dongdaemun, and a few hours snoozing on the floor in the motel room (we sqeeze all that we can in there!)…

Well, let’s just leave it that after getting up and out, bustling over to Central City terminal to lock up the bags for the day and get some tickets for back home, back over to Myeong-dong/Namdaemun market, this time, I was still itching to walk about the park instead of the market with nothing specific to buy this Memorial day holiday.


What’s there to do in the neighborhood? Grab a bottle of water and head up to HL/SL-009 Namsan, bypassing the crowds waiting for the cable car and jetting up the steps. After all, it’s been just about a year (minus a month) since I’d last been around on this one pointer.


Once on the “summit” there are crowds and whatever you’d expect to see on a weekend, so I went slightly to the east to have just a wee bit of space to make some contacts. I must mention at this point, one of the ulterior motives for this 미니산행 was that DS1SLM was up activating HL/SL-001 도봉산 so I thought I’d oblige, give him some points while gathering some of my own…


In coordinating with SLM getting the contact was proving to be on the difficult side, in fact he claimed he could copy me quite well, though I could just barely receive him (we were both operating via HT). After a while, it dawned on me that my receiver was being overloaded from the broadcast tower, which Namsan is. Proceed to find a better place downhill, behind some object to provide some RF “shade”…this was hard, I was putzing around behind trees, stone walls and the like, when almost giving up, I tried heading back up the hill to under the tower.


Last year, without thinking, we simply sat down in the shade with some cold drinks (thanks, Zoom!) in the terrace café under the N-Tower, overlooking the city, the river, up to HL/SL-002 관악산, etc. Duh, we were perfectly in RF shade, directly under the antenna firing out horizontally. QRM was at peak S3, but mostly S0.


It was from this QTH that I had my final activating QSO with DS1PRD, across the river, discovering that he’s actually from the Iksan area! After that, I gave a few more CQs at 1W with no response before the battery was fully dead (remember that ultra-long hike yesterday?).

I’ve never really had the time to piddle around Namsan Park (still haven’t), so decided I’d descend via a different route, going more to the east to take the rubberized road down (the first time I took it, I went the wrong way). To this point, I still haven’t figured it out, actually. It’s not straight up or down, there are maps prominently posted along the way, but half of them in braille, not even any Korean side by side. In the end, I took a nice “short cut” of wooden stairs cutting through a ravine leading down through the trees.


This wasn’t before first paying a visit to the geographical center of Seoul, conveniently located smack-dab on top of the city’s mountain. Depending on who you ask, it could very well be the center of the universe ;p



In addition to the cable car, another means of transportation to the top is a fleet of electric buses which happen to have a charging station located a few hundred meters down summit.

Alas, a good way to unwind the rest of the way at the end of a three day weekend. Though, in all seriousness, my recommendation to future activators is just to chill on the terrace in the shade for a leisurely “armchair activation.”



Another new activator in HL!


At the last hamfest at Yonsei University I had the chance to meet HL2OLP, a new activator out in the hills of Korea. He’s been primarily activating on HF and CW in the Gyeonggi area around Seoul and Incheon.

He’s been making the rounds at HL/GG-094 삼성산 (Samseongsan), HL/IN-021 철마산 (Cheolmasan), HL/IN-006 계양산 (Gyeyangsan) and most recently HL/GG-015 북한산 (Bukhansan (Baekundae)) on April 20. Speaking of Bukhansan: DS2SHC will be operating from 백운대 on April 30 (this upcoming Saturday)–you can listen for him on 144.840 FM after 11 AM.

Chang-shin Kim(HL2OLP, 김창신) has so far contacted Korean stations as well as ops abroad, including: , , , , , , , , , , , , , , , , , , and .

I look forward to having a S2S QSO with him in the near future! Good luck, Chang-shin!



SL-004 Inwangsan on 20100710

Here’s a more “real” activation (still only 1 point, but the fact there wasn’t a rubberized two lane road going to the top somehow changes things!) on Inwangsan (인왕산) (Wikipedia reference)

Just barely squeaked by with 4 QSOs (it was at dinnertime and my antenna was polarized the wrong way)…it was a trial for the new antenna I just received that afternoon from DS1DAT made by DS1DFK.



I also discovered that there’s a fortress wall on top of this mountain, as well as a mini-military installation.  Emphasis on the mini.  Obviously no photos of that.  However, we do have some shots of the fortress renovations underway…


In the self portrait of me above you’ll note the “old” summit marker (“old” dates back to 1994, in this case).  New is, well, new, as in 2010.  Take note of the RFID component…


Good to know:  The mountain is more or less “closed” on Mondays and days following holidays to protect the nature and let it rest (and to kick out the partyers who overstay their welcome).  There is military there, so don’t be put off by the fences, barbed wire and cameras…That’s on the approach from Gyeongbukgung Station (which seems to be the main approach, but not that evident) as opposed to Muakjae Station (shorter ascent, harder to find trail head).


There will be a video in the future, of course.

HL/SL-009 남산 운용 –20100710

truly extreme SOTA here--out in the elementsSaturday morning stroll up Namsan–to make a leisurely 6 QSOs via HT with one S2S with DS1DAT who was with DS1DFK activating HL/SL-002 Gwanaksan. Namsan is popularly known as the site of the N-Tower.

A video will be uploaded shortly–stay tuned!
