I use a Tecsun Pl-880 I got used with an AN-80 antenna I hang in my room.
I've managed to get QSL cards from NHK-World on 6105, WWV on 1500, CHU on 7850, WINB on 9265, and Pop Shop Radio on 5950 (WRMI)
Sent reports to WWCR, WRMI, and Radio Havana Cuba
Also, I learned that Radio Romania and New Zealand no longer QSL.
I'm gonna QSL China, Exterior de Espana, Turkey, WTWW, Radio Rebelde, and World Christian Broadcasting
I recommend listening WRMI, since it has a diverse range of music, such as Cruisin' the Decades (UTC 2-3 Sun), The Mighty KBC, Encore/Radio Tumbril, Pop Shop Radio (UTC 1-2 Mon), Alt Universe Top 40, Imaginary Stations (when that comes on - seems kinda random to me idk), and DEFINITRLY Radio Catface (UTC 3 Mon), because it's the only indie-type music on shortwave that I can find so it's a really unique listen.
Also, the NHK-World (6105) Has a singing contest called "Nodo Jiman" late on night and some music.
I also listen to a lot of news reports, and if your trying to learn Japanese, most of their foreign language services have brief lessons at the end (the 6105 freq doesn't have this though from what I can tell)
Anyway, that's my overly long post. Have fun, glad your into this hobby. I've been doing for a few months and the world seems so much smaller and cooler now :)
