I realize Costa Rica is no Heard Island but if anyone needs this as a DXCC entity I’ll be down in TI7 land operating at TI7/W6PNG Thursday Feb 28 - Sunday Mar 3rd with a couple of friends.
Main event is the ARRL DX SSB contest where hopefully our 100 watts and a bit of flimsy wire makes us a workable US target.
Contact me if interested in trying to organize a sched.
It is no a Heard Island, but there are only about 100 active amateurs. There is a lack of CW operators. My suggestion is to operate from Casa Talamanca at Plata del Coco. Gunter (TI7WGI) has antenna towers, and you only need to bring your radio.
