During ‘On-Air’ chats, members of WoSARS often hear me describe some of the fun that can be had on microwave frequencies; especially for myself 13cms (2.3/2.4GHz) whilst out Activating a SOTA summit.
These escapades evolved from the creation of the GM13 GROUP of likeminded amateurs in 2017.
Following the successful launch and operation of OSCAR 100 in 2018/19; this has opened up the opportunity to predictably work distant stations around Europe, Asia, Africa and even South America. Using the Satellite’s 13cms UP and 3cms (10GHz) DOWN translator; some of our hardy band of SOTA-microeers have put together kit to access this facility.
Andrew G4VFL was an early adopter of this challenge (see WoSARS Web March 2020 Article – HERE ) along with his ‘partner-in-crime’ Nick G0HIK; they have been progressively ‘knockin’ off summits in LD (Lake District) and SS (Southern Scotland).
Now not having quite the enthusiasm of the ‘twosomes’ as to lugging dishes up summits, I do however benefit from potential Summit-to-Summit’s S2S’s, utilising my 8 ele Bow-Tie and SG transverter (2W out) and the gain of the dishes at the other end.
Popping down to just below the 2.4GHz UP Oscar frequency (2399.950MHz), it is possible to work Point-to-Point (S2S) utilising the high gain of the dishes – with the majority of the contacts being made on FM (of course falling back on SSB/CW on marginal paths).
And Wednesday 19th (May) this week, saw us all heading out on a predetermined series of Activations; an LD for Nick (and Chris M0KPW), and SS’s for Andrew and myself.
So why not join us. Just bring along your kitchen microwave to a suitable top – you never know who you’ll work. 🙂
And I’ll leave the last word to Nick:
“……… Hi Guys,
Thanks for the contacts today, it was staggering how strong you both were. I think GM/SS-037 was 110km and GM/SS-142 was 99km. Sorry we could not stay around for your 2nd one Jack …………..”

Frontier-women conquers Summits – By Péter Váry O.
Women usually go to the hairdresser, go shopping, and usually do “feminine” things when they have time off. Éva Gajdó, a teacher of computer science at Tivadar Puskás Vocational High School, who teaches programming on CNC (computer-controlled) machines, does not like this. She climbs mountains. And up there on the summit, she transmits radio signals. It may seem a strange combination at first, but it is recognised as a sport. Established for less than a decade and a half, it is already gaining in popularity and Éva Gajdó has accomplished something very big in this sport in a short time. Her success is the envy of her fellow men, which as she is a Szekler, does not often happen. (The Székelys derive their name from a Hungarian expression meaning “frontier guards”.)
Éva Gajdó has been roaming the mountains since she was a child. She became a true lover of climbing when one of her teachers took her on an expedition. Then life sank into the ordinary course of events: she got married, the children came and there was little opportunity to conquer the peaks.
Several years ago however, talking about childhood dreams with a group of friends, Eve recalled that when she was sixteen, she was determined to climb Mont Blanc. But it seemed it would remain just a dream. Then, a few days later, a friend told her that the Szeklers were hiring amateur climbers and heading to Mont Blanc.”I didn’t think, I called Tulit Sombor, and applied,” says Eve.
Two months of tough training was unsurpringingly not enough to qualify for the team. She also found her gear was unsuitable. She hiked in velvet pants and her ancient boots caused problems; the two months were agonizing. But Sombor reassured her that she had all the skills and with a little training, could climb Mont Blanc. It became a passion and she has not missed a weekend in five years and even celebrated New Year’s Eve on top of a mountain.
She applied for another expedition, but unfortunately before her departure she sprained an ankle. She was able to climb this year, but couldn’t use the radio.
In order to understand why Eve should have been broadcasting radio signals from the highest peak in the Alps and what activation means we need to introduce the sport called SOTA. The acronym comes from ‘Summits on the Air’, this radio competition was launched in 2002 by radio amateurs who combined there passion with mountaineering.
The competition (Edit: SOTA is not a contest it is based on your own self fulfilment) consists of climbing the designated peaks – at least 150 meters above its surroundings – by hiking, and from the ‘summit’ the hiker must establish at least four radio links with other radio amateurs around the world (meaning activation).
The peaks score between 1 and 10 according to their height and can be activated once per year.
The map provided by NASA to radio-operators in Romania has about two hundred SOTA peaks, of which 250-300 can be climbed under normal conditions, ie on a more or less well-marked path.
A walkie-talkie can achieve the necessary score if it is successfully activated, that is, it has been climbed and a minimum of four mandatory contacts made. After earning a thousand points, the title ‘Mountain Goat’ and trophy will be awarded to the competitor. Achieving a thousand points usually takes several years to complete. Eva did a special job here too.
Eve met a man in Jezer (Bosnia and Herzegovina) on a hike, while trying to establish a radio connection at the summit. He was interested in the subject, because there is a radio club at Puskás Tivadar Vocational School, Budapest, and he was wondering how to create something new and interesting for the students. At that time, he had no plans to start radioing himself, or that hiking would become a competitive climb. He asked a teacher at Transilvania University in Brasov, Csaba-Zoltán Kertész, if he would come and introduce SOTA to the children.
Since January last year, Csaba has gone to St. George every Tuesday, trying to infect students with the radio virus. Because amateur-radio amateur is well-suited to the younger generation, SOTA is becoming more and more popular, including foxhunting, but knowing the basics of radio is essential.
Eve had no childhood dream of becoming a radio amateur but her dedication to teaching led her there. Csaba Kertész enthusiastic for the Tuesday afternoon classes included taking the students on several trips, where they could experience “live” what walking radio was about.
Eva thought that if Csaba couldn’t come for some reason, it would be a good idea if someone could take care of the children. But to do that she needed a radio license.
– You have to take a very tough exam: electronics, knowledge of frequencies, first aid. You have to learn the phonetic alphabet that is used in radio, to know what phrases can be heard and what are not, so there are ethical rules as well.
She passed and received her radio callsign: YO6EVA. (YO = Romania ID, 6 represents the area, and EVA unique, individual)
I’ll do it in a year – As I had passed my exam, I went with Csaba to a SOTA marathon. It was staged in the Bihari Mountains, Romania, and was worth exactly one thousand (1000) points for someone who had done it for six or seven years. I told Csaba, as I go to the mountains, I could earn a thousand points in a year.
In the beginning it was really hard because I didn’t know anything about radio, I didn’t have any equipment, I borrowed a walkie-talkie, which had only 300 meters range I went up the mountain and couldn’t activate it. I persuaded Csaba to come with me to collect points, but the points accumulated very slowly. Finally, I bought a serious radio, and then the “party” started.
– Has a thousand points been reached in one year?
– Not easily, but it was. I went to Nagykő (Transylvania, Romania) alone and for the first time spoke on the radio and I was so scared I switched it off.
There was bad weather at Nagyhagymás, I went up four times, but never activated it; in minus ten (-10) degrees activating radio was not a lot of fun.
Disappointed I told Csaba it wouldn’t work for me, but with the support of friends, somehow I hung on and continued. The biggest challenge was to get to the summits that I would not have gone to otherwise, I had to cut through a sign or path like in the jungle. Finally a thousand points were reached, 131 different peaks in a year.
– 131 peaks in a year, one average every three days.
– Most were the four eight-point peaks in a single day, 40 kilometers of walking at 3500 meters.
With her unique performance, Eve has earned the envy of many of the male walkie-talkie operators, She reached a thousand points in May – since then, the number of activations in Romania has increased, with another SOTA marathon being organized by December 1, interest in the sport has revived..
Although Eve has achieved what she set herself to do, she does not intend to stop walking but not as intense as before. Also because all of the closest peaks have been activated and new ones are usually a two-day hike away – She would like to climb the highest peaks in Europe, but she would need to take another license before she could broadcast abroad.
Eve talks enthusiastically about everything, but when it comes to the mountains, her eyes shine the most. What does mountain climbing, mean to her?
Its an obsession with me, an addiction. The mountain has given me so much, I try to pass that on to the students. Everything revolves around the mountain, I don’t go to the beautician or to the shops, and my daughter says you have seven pairs of hiking pants, but you just don’t have anything to go to school. SOTA has exposed a whole new side of climbing and fox hunting.
YO6EVA Eva Kelemen Gajdo reached a thousand points in May 2018 becoming the first YL Mountain Goat in Romania. An admirable achievement, showing great dedication and a nice example to follow. What is truly amazing, that she achieved this goal in just under a year after obtaining her HAM license, learning all about what it takes to operate a radio while hiking around the summits of Romania, whatever the conditions or difficulties. Hail, the rain, bad propagation could not deter her in achieving her target.
Romanian yl Éva YO6EVA active on Argentina Mountain
yl from Romania – YO6EVA Éva Gajdo and Csaba YO6PIB with colleagues from SOTA Mendoza, Argentina, activated SOTA (LUM/PC-004) Jan. 2020.
Éva Gajdó YO6EVA and Csaba-Zoltán Kertész YO6PIB came to climb and activate Aconcagua during the first two weeks of January 2020. Aconcagua (LUM/PH-001) is the highest summit in the SOTA programme, altitude. 6960m.
However they could not reach the summit due to very high winds. They began their descent as per schedule feeling very disappointed, especially regarding the Mendoza radioclub friends who had supported the expedition, prepared to ‘chase’ (on air) and even to make ‘summit-to-summit’ contacts. They made 2 attempts and spent 3 nights at over 6000m.
On their arrival back in Mendoza, Eva and Csabone had one day left before catching their plane home to Romania. Tthe Argentina SOTA group was also disappointed and it was decided to activate another summit where they could communicate in VHF and HF as originally planned.
The route was chosen so that Eva and Csaba could enjoy seeing animals from the local Villavicencio reserve, mostly guanacos. The group was also lucky enough to see several condors flying over the activated peak in the Paramillos area.
The group were surprised by the number of active stations that made contact. Many operators were keen to communicate their enthusiasm at contacting the visitors and to wish them a safe journey back to Romania. Unfortunately propagation conditions for HF were not good, although some contacts were achieved.
The Argentinians were happy that Eva and Csaba had managed to activate an Argentine summit and although it was not Aconcagua, that they had enjoyed the local hospitality of Mendoza.
LUM/PC-004, Paramillos 3356m This peak is not well known and does not have a name, near Termas Villavicencio, Mendoza (Argentina). Value 8 SOTA points,

Aconcagua [32°39’12.35″S – 70° 0’40.00″W]
Aconcagua is a mountain in the Principal Cordillera of the Andes mountain range, in Mendoza Province,. east of Argentina’s border with Chile. Aconcagua is the highest mountain outside Asia, at 6,961 meters (22,838 feet)
The mountain and its surroundings are part of the Aconcagua Provincial Park. Aconcagua Provincial Park is 185 km away from the city of Mendoza, near the border with Chile.
The mountain has a number of glaciers. Aconcagua is arguably the highest non-technical mountain in the world, since the northern route does not absolutely require ropes, axes, and pins. around 3,500 climbers tackle Aconcagua each year with a success rate of about 60%. Aconcagua has one of the highest death tolls of the world’s highest peaks.
There are severe winds and low temperatures, but it’s Aconcagua’s altitude that presents the greatest problem. Every year sees several deaths on Aconcagua – mainly people who underestimated the task and help may take several hours to arrive. Climbing the mountain will require on average of around 21 days.
The official visiting season is from November 15 to March 15. During the summer, the temperature at night above 5,000 meters (16,400 feet) is about -20°C (-4°F), and the usual temperature at the summit is -30°C (-22°F). In the rain shadow of the Andean crest, the park is one of the most barren parts of the Andes, with only a discontinuous cover of prostrate shrubs and grasses. At the highest altitudes, it is almost pure scree and snow.
I was working Andrew – G(M)4VFL on GM/SS-056 on 13cms (2.3GHz) FM last week and he happened to mention that earlier in the week he had worked VU (India) to activate G/LD-030. I was intrigued – of course via OCAR 100 – HERE . 13cms Up & 3cms down.
I asked him if he had a picture, and indeed he has forwarded a nice shot.
Now does anybody fancy working out the path distances? 🙂
