Operating Ham radio from Costa Rica

I traveled to Costa Rica in 2023 with my portable antenna and got to operate from there. The pacific coast is a truly beautiful place with many different amazing things to do. This is one of the beautiful sights we got to visit.

Other than all that great stuff, I brought my radio equipment with me. I had my Yaesu FT-100 with me for HF operation and my Wouxon KG-Q10H for handheld operation.

I did manage to make one 2 meter contact using an external 5/8 wave antenna on my handheld. This was done via the repeater system in Costa Rica. This was done with the balcony using a mag mount antenna.

Originally I had booked a ground floor room, but got upgraded to almost the highest quality room in the resort I was at. This meant I could setup my antenna right out on the balcony. The balcony was actually enormous and shared with several other rooms. But I never saw anyone else using it so I had it all to myself to operate from.

So with this setup I was able to get the antenna working with a horizontal polarization far up above the coastline. The antenna is pointing almost directly south so the radiation pattern should be east-west with that configuration. I ended up mostly using the antenna on 15m & 40m. The antenna is far more efficient on 15m, but the lowest SWR I could get was about 1.8. I think the balcony was creating a bunch of capacitance to ground from the antenna that was making it difficult to tune on the higher bands. At night time, 40m was absolutely great however. I could run up to 100 watts on SSB and 40 watts on digital modes. The grid square for my location there is EJ79. I identified my call as KK4KYE/TI8, since I was in Costa Rica.

At one point while operating from the balcony I actually got to watch a mother humpback whale & her calf breaching in the ocean!

15 meters operation

On 15 meters I only used digital modes. It turns out FT8 frequencies are quite crowded nowadays. When I transmitted FT4 I actually got more signal reports on PSK reporter

Unsurpringly I had no issue working stations as far away as Japan without any problem.

40 meters operation

I only used 40 meters operation at night. I didn't realize this but Europe is reachable from Costa Rica almost entirely across open ocean. I pretty much immediately was able to use FT8 to contact Ukraine.

I made multiple contacts into Europe using FT8 or FT4 with no problem. I also use JS8 and had multiple long QSOs with Hams in the United States!

Surprisingly, 40 meters worked great on SSB as well. I made voice contact with Romania and Bulgaria no problem. OE3DIA, LZ2ZF & YO7MPD were all operating in group and gave me signal reports from 5-7 to 5-9. I received all of them at 5-9 or better.
